203-636: The Audi R18 is a Le Mans Prototype (LMP) racing car constructed by the German car manufacturer Audi AG . It is the successor to the Audi R15 TDI . Like its predecessor, the R18 uses a TDI turbocharged diesel engine but with a reduced capacity of 3.7 litres and in a V6 configuration. For the first time since the 1999 R8C , the Audi Le Mans prototype used a closed cockpit design. The R18

406-505: A continuously variable transmission (CVT). The CPC-KERS is similar as it also forms part of the driveline assembly. However, the whole mechanism including the flywheel sits entirely in the vehicle's hub (looking like a drum brake ). In the CPC-KERS, a differential replaces the CVT and transfers torque between the flywheel, drive wheel and road wheel. The first of these systems to be revealed

609-494: A lithium-ion battery with scalable capacity or a flywheel, a four to eight kilogram electric motor (with a maximum power level of 60 kW (81 hp)), as well as the KERS controller for power and battery management. Bosch also offers a range of electric hybrid systems for commercial and light-duty applications. Several automakers have been testing KERS systems. At the 2008 1000 km of Silverstone , Peugeot Sport unveiled

812-421: A 1:39.201 to lead the field, and the #8 had the third-fastest time. Repeating the result from the first practice, the #7 ended up back on top at the end of a dry second practice. The #8 finished fourth. During the last practice, Porsche set the fastest laps of any of the practice sessions and took the top two spots. The #8 and #7 finished third and fourth respectively, decreasing on their times in comparison to

1015-434: A 4.2-litre naturally-aspirated V8. In seasons 2017 through 2020, the engine produced about 600  bhp . Dallara , Onroak Automotive (Ligier), Oreca and the joint-venture Riley Tech / Multimatic were selected by FIA as the four exclusive chassis constructors, which must be closed-cockpit designs. Before the start of the 2021 season LMP2 cars have been slowed down to ensure the necessary lap time difference between

Two minor incidents were reported during testing of various KERS systems in 2008 . The first occurred when the Red Bull Racing team tested their KERS battery for

1421-727: A V engine exhausting outwards to their respective turbochargers. For 2012, Audi introduced an evolution of the original car called the R18 ultra and R18 e-tron quattro , which won Le Mans. Both the Ultra and e-tron quattro R18 were run at the 2012 24 Hours of Le Mans . In addition to the changes required by the regulations (reduced air intake restrictor and 60 litre fuel tank) the car was completely reworked to reduce weight. These changes included Xtrac sequential electrically activated 6-speed racing gearbox with gearbox housing made of new carbon-fiber composite with titanium inserts, carbon clutch, changes to

1624-593: A battery system, in contrast to the previous Porsche 911 GT3 R Hybrid that used a flywheel system. A KERS using a carbon fibre flywheel, originally developed for the Williams Formula One racing team, has been modified for retrofitting to existing London double-decker buses . 500 buses from the Go-Ahead Group will be fitted with this technology from 2014 to 2016, anticipated to improve fuel efficiency by approximately 20%. The team who developed

1827-460: A brand new car, dubbed by the simple name of 'Audi R18' was fully revealed in its final competition design in March 2016. Mostly every peripheral within the design element of the 2016 car was fundamentally different from its predecessors. The front end and overall vehicle length changed, with the nose of the car becoming slimmer than ever before. At the front end of the car, the airflow is directed to

2030-418: A broken throttle linkage, placing it behind four laps, eighteenth place overall. They would need to mount a rapid comeback to get ahead of the two Toyota TS040 Hybrids to reach the minimum position needed to secure the drivers' championship (assuming the #7 Audi wins). A full course yellow, gave the two Audis the advantage over the lone Porsche in front, leading to the #8 and #7 placing first and second by

2233-400: A failure of the gathering of energy to the front axle of the car. Having to be wary of the time it was losing to the #1 Toyota, the #17 Porsche team decided to send the car back out onto the track without it front axle energy storage system active, with only the exhaust energy recovery system functioning. At the conclusion of the race, #18 Porsche was able to hold off the #7 Audi by over

2436-530: A flywheel on a bike frame and connecting it with a CVT to the back wheel. By shifting the gear, 20% of the kinetic energy can be stored in the flywheel, ready to give an acceleration boost by reshifting the gear. Automobile Club de l'Ouest , the organizer behind the annual 24 Hours of Le Mans event and the Le Mans Series , has promoted the use of kinetic energy recovery systems in the LMP1 class since

2639-462: A half seconds over the second place #18 Porsche . In third was the #1 Toyota , about fifteen seconds back. The #8 Audi finished fifth place, three laps down. After securing a hard-fought win in Silverstone , the championship moved onto Spa-Francorchamps for the 6 Hours of Spa-Francorchamps . The first practice was run under wet conditions, and it slowed the pace of the track greatly, as

2842-413: A high strength CFRP with an aluminum honeycomb core. The hybrid system is encased in a high voltage protection system. The car was first tested in late 2015 ahead of the 2016 season. Audi's regular season car numbers did not change from last year, as the main two cars still sported the #7 and #8. The driver lineup consisted with the same driver lineup as last year, assigned to the same car numbers, with

3045-465: A higher MJ class reduces the fuel capacity to 49.9 liters in exchange for a higher engine power output of over 390 kW (520 hp). The foundation of the V6 TDI engine still revolves around the variable geometry turbocharger , with a 120-degree cylinder bank angle, and torque output of 850 Newton meters, in use since 2011, but now consumes 32.4 percent less fuel in 2016 in contrast to 2011. Much like

3248-463: A lap being trapped in the gravel while the leading Audis lapped them. The Toyota hybrids were able to continue after being rescued by safety marshals. By the end of the third hour, the Porsche trailing the lead Audi in hour two led the race. Between the end of the third hour and fifth, the Porsche continued to lead, and the #2 switched positions with the #1 going into the final hour, as Audi

3451-520: A lengthy pit stop that included a driver change for the #7. Not much later, the #7 would have a spin, resulting in the #2 Porsche passing it for second place. Chaos ensued for the #1 Porsche at the end of the hour, with a crash involving a GT AM car. The incident would prove terminal for both car's chances to complete the race. Trouble would also be in store for the #8, as the car stopped off track with MGU problems. A full course yellow would be deployed to clean up both incidents. The #2 Porsche gained

3654-411: A lithium-ion battery was used instead of a capacitor to store and supply energy. For the opening practice session of the season, Porsche was able to secure the first two positions, both a second and a half clear of the next best LMP1 runner, their best time a 1:42.182. The two Audi cars, the #8 in fourth and the #7 in sixth were separated by two and a half seconds with the #8 running a 1:43.917. In

3857-403: A mechanical problem, and would lose three laps by the end of the hour, placing it fourth, between the #7 which was one lap down in third and the #8 three laps down in fifth. The #7 Audi driven by André Lotterer at the time set a new race lap record ( at the time, which was eventually broken in 2019 ) of 3 minutes and 17.476 seconds. When the race concluded, the #19 Porsche won the race, and

4060-462: A minute to win the race. The duo of Toyotas finished third and fourth, both three laps down, and the #17 car finished fifth, nine laps down. The #8 rounded off the LMP-H category, eleven laps down. The #17 Porsche was still able to earn the drivers championship by a mere five points to the #7 Audi , 166 to 161. With plans to reclaim the manufacturers' title which Audi have not won since 2013 ,

4263-492: A race lap record on the Sarthe circuit of a 3-minute and 17.647 lap, and the pace continued to place himself second by the end of the hour with the #7 behind. As the sun began to set over the track in the seventh hour, the #9 was able to pass the #17 Porsche on raw pace after a pit stop, and the #7 followed in third. By the end of hour ten, the Porsche would regain the lead over the #7 and #9 in second and third places. Entering

4466-505: A revised V6 TDI engine with an electric turbocharger, upgrades to the flywheel accumulator system and an exhaust heat recovery system . The system captures the thermal energy from the exhaust and can add power to either the turbocharger or the flywheel accumulator system. Audi later opted not to race with the second Energy Retrieval System, which is known as a Motor Generator Unit-Heat [MGU-H] in Formula One, because it did not result in

4669-466: A role in determining the outcome of the race. Although the #7 was passed by the #18 on the Kemmel Straight with forty-five minutes to go, the Porsche soon took a pit stop for fuel only. Audi would react to the pit stop by leaving the #7 out for a few more laps until pitting in on lap 164 for fuel only, with the gap between the #7 and the #18 at fifty seconds. The #7 Audi would go onto win

4872-463: A season that Audi won as a result of fast race pace and good consistency. Audi would evolve the R18 e-tron quattro into an entirely new and different looking car from its revised 2013 predecessor to adapt to the changes that the new LMP1 regulations (for hybrids) presented. A larger 4.0 L engine (producing over 400 kW (540 bhp)) would power the rear of the car and one MGU hybrid system (producing over 170 kW (230 hp)) would operate in

5075-424: A second within each other taking the first three spots. They were a second over a duo of Toyota TS030 Hybrid cars, one being 2013-spec and the other 2012. The race would show Audi's strong pace, but it was neutralized by Toyota's better fuel consumption in its 2013-spec car, making for a very tight race for Audi. However, a mechanical problem in the closest challenging Toyota provided Audi with an easy 1–2–3 finish as

5278-513: A single Garrett ( Honeywell Turbo Technologies ) TR30R VGT turbocharger, as opposed to the twin TR30R configuration of both the Peugeot 908 HDi FAP and the previous Audi R15 TDI . The R18's V6 engine exhausts inwards between the cylinder banks, where the turbocharger is placed. This is called a 'hot valley' configuration and is opposed to the traditional configuration with each cylinder bank of

5481-546: Is 875 kilograms. Audi upgraded the R18 to the 6 MJ class, and for the new car, an electrochemical battery storage system will accumulate energy in the hybrid system instead of a flywheel, which will be located in the monocoque. The MGU (motor generated unit) at the front axle will gather kinetic energy through the rotation of the wheels until braking and disperse to help the car accelerate. The MGU can store and output more than 355 kW (476 hp) (limited to 304 kW (408 hp) at Le Mans). Consequently, switching to

5684-520: Is also the first racing car from Audi to feature hybrid power. Although Audi have previously given each new developed model of endurance racing car a distinct model number, the head of Audi Sport, Wolfgang Ullrich , suggested the R18 designation for Audi endurance racing cars could be used for the foreseeable future. There were five further evolutions of R18 until Audi quit the FIA World Endurance Championship in 2016. As

5887-452: Is used to supply power needed by vehicle electrical systems. When used in conjunction with Mazda's start-stop system , i-Stop, the company claims fuel savings of up to 10%. Bosch and PSA Peugeot Citroën have developed a hybrid system that uses hydraulics as a way to transfer energy to and from a compressed nitrogen tank. An up to 45% reduction in fuel consumption is claimed, corresponding to 2.9 L/100 km (81 mpg, 69 g CO 2 /km) on

6090-566: The 6 Hours of Silverstone . Toyota had brought a revised version of the successful TS040 Hybrid that won them both the drivers' and manufacturers' championships in the 2014 FIA WEC season . Porsche , newcomers to the FIA WEC in 2014, have also updated their prototype, most notably moving their prototype to the 8MJ class. In the first practice, the Audi #8 topped the time sheets setting 1 minute 42.121 second lap. The other Audi , #7 finished

6293-403: The 6 hours of Bahrain , and Audi would not dominate as they did for the majority of the season. The #1 car started the race in third and the #2 in fourth. The #1 would finish second place and the #2 would retire due to mechanical issues. Despite the result, Audi would still win the manufacturer's title by sixty-four and a half points. The season for Audi's R18 e-tron quattro would be defined as

6496-516: The Audis , allowing it to leap both the #7 and the #8 by the end of the race. The final standings were the #17 and #18 Porsches finishing first and second while the #7 and #8 were third and fourth. Porsche claimed the manufacturers' titles with the first and second-place finish. Porsche would also have the opportunity to clinch the drivers' (with the #17 Porsche driver lineup) with a fourth-place finish or better next round. The #7 Audi driver lineup

6699-509: The FIA allowed the use of 60 kW (82 PS; 80 bhp) KERS in the regulations for the 2009 Formula One season . Teams began testing systems in 2008: energy can either be stored as mechanical energy (as in a flywheel) or as electrical energy (as in a battery or supercapacitor ). With the introduction of KERS in the 2009 season, only four teams used it at some point in the season: Ferrari , Renault , BMW and McLaren . Eventually, during

6902-519: The LM GTE's and Prototype racers. In qualifying, the #7 Audi , after being mostly at the bottom of the LMP1-H standings for both of the free practice sessions, the #7 was able to rebound to earn a pole for the race. Following averaging a tenth behind was the #8, which snapped an 11-race streak starting from pole for Porsche . The race got under way with the air temperature at 9 °C (48 °F) and

7105-402: The LMP1 class was altered, and as a consequence, the e-tron quattro received an additional 0.5 kg/h of fuel flow to its V6 engine powerplant and a 0.5-litre reduction in fuel tank capacity from 53.7 to 54.2 litres. The first practice session of the race week was affected by weather in the area. That did not stop Audi from setting the pace during the first session of the week. The #7 set

7308-400: The LMP1 grid. In the race, Audi would find pace, particularly with their #2 car, as Lotterer set the best lap in the first hour at 1 minute 46.388 seconds, positioned in fourth place by the conclusion of the first hour. The second hour would see the lap time lower to a 1-minute and 46.126-second lap by the #2 car as well as a position gain by one position, to third. The #1 car's position

The system is claimed to be much more affordable than competing electric and flywheel systems and was expected on road cars by 2016 but was abandoned in 2015. In 2020, FIAT launched the series of the FIAT Panda mild-hybrid with KERS technology. KTM racing boss Harald Bartol revealed that the factory raced with a secret kinetic energy recovery system fitted to Tomoyoshi Koyama 's motorcycle during

7714-513: The Peugeot 908 HY , a hybrid electric variant of the diesel 908, with KERS. Peugeot planned to campaign the car in the 2009 Le Mans Series season , although it was not allowed to score championship points. McLaren began testing of their KERS system in September 2008 at Jerez in preparation for the 2009 F1 season , although at that time it was not yet known if they would be operating an electrical or mechanical system. In November 2008, it

Two of Toyota's drivers, Anthony Davidson and Sébastien Buemi in

8120-473: The Porsches . By the end of the first hour, the #7 sat in second and the #8 sat in fourth, both cars behind Porsches . By the beginning of the second hour, Audi would struggle to match the Porsche's pace and the #7 dropped back to third and the #8 still in fourth. As the hour went on the Audi cars would pickup more and more consistent speed. By the end of the third hour, Audi would make up ground and

8323-608: The Toyota in second. At the end of hour 4, the #2 would slip back to second, but would eventually battle back to win the race, twenty-three seconds ahead of their rival Toyota . The 6 hours of Fuji in the 2013 season would be the shortest race in FIA WEC history. Despite Audi qualifying the #1 car on pole and #2 car in fourth position, the race would only last eight total green flag laps, which started under safety car due to heavy rain. The Audi #1 would pit for service in response to

The new gearbox was electrically controlled instead of pneumatically controlled, saving weight by eliminating the pneumatic system. Despite the capacity reduction, the 3.7L V6 is claimed to develop more than 397 kilowatts (532 bhp) of power, less than the outgoing R15. The new engine has

8729-458: The #1 Toyota in fourth place. In the fourth hour, the #7 slipped back to second after having to deal with a faulty wheel nut, and by consequence, the #7 Audi had to take an extra stop to change a wheel. In the fifth hour, the #8 had a three-minute stop and hold penalty after the #8 crew fitted the car with the wrong front tires, requiring an additional stop, taking the team over their maximum allocation of thirty-four tires. The #17 Porsche had

8932-525: The #1 car's chances of finishing the race. That left the #2 Audi to survive the remaining five hours, in fourth place, one lap down behind two Toyotas and a Porsche in that order. By the end of hour two, the #2 Audi had slipped behind the Rebellion Racing , entry three laps down. The car would pass the Rebellion by the end of hour three. By the end of hour 4, the #2 would be completely out of

In the first two of the practice sessions, Toyota led and in

9541-419: The #1, which followed behind three tenths off the pace. The race would prove to be a worthy challenge for Audi by their rivals Toyota. By the end of hour 1, the #2 car sat in second place behind the lone Toyota machine and the #1 car in fourth behind the Rebellion Racing entry, one lap down from the lead. However, during hour two until the end of three, the #2 car regained the lead, being followed closely by

9744-479: The #1. Toyota would finish the season not only with the drivers title, but with the manufacturers' title as the Toyota TS040 Hybrid proved to be the best overall LMP1-H during the season, combining speed, reliability, and solid fuel efficiency to consistently produce good results for the majority of the rounds. Audi would revise their R18 e-tron quattro. Audi chose to upgrade the prototype to

9947-490: The #17 finishing second. The #7 would be the only Audi on the podium, finishing third, two laps down. The #8 and #9 would complete the race as well, in fourth, three laps down and seventh, eight laps down. The result would place Porsche in the lead in the manufacturers' points championship, with a lead of sixteen points over Audi . For the 6 Hours of Nürburgring , the EoT (Equivalence of Technology) in regards to fuel flow for

10150-421: The #2 Porsche, placing the car in sixth after the issues were resolved. The #8 Audi would move up to second place and try to catch the leading Porsche , but around forty minutes into the hour, the #5 Toyota was able get by the #8 Audi and eventually to the lead past the #1 Porsche , with the #7 Audi behind in fourth place. In the second hour, the #1 Porsche would suffer from two tire punctures, dropping

10353-434: The #2 after the end of hour three, but would eventually regain the lead again by the end of hour five, thanks to a solid stint by McNish and the lack of hybrid drive in the #1 car. The #2 car would win the race after battling with its sister car throughout the race, winning an entire lap over Toyota . The addition of a third entry was prepared by Audi prior to the 6 hours of Spa-Francorchamps . The #3 car would be driven by

By the end of the second hour, both Audi cars moved back a position each, the #2 car in fourth and the #1 in fifth. At the end of hour three, both cars were lapped by the fast-paced Toyota , and, in the end, the #2 car could not catch the Porsche in third position, who was on the same lap. The #2 kept losing time to

10759-418: The #2 car remained in sixth. By the end of the fifth hour, both cars moved up the order, the #1 in third and the #2 in fourth. The finale of the season concluded with the #1 car taking a podium position in third and the #2 car settle back to fifth. Porsche won the race, their first of the season. All throughout the race Audi brought a significant challenge to get both of their cars on the podium, particularly

10962-426: The #2 for fourth respectively. The race would play out as the tale of two halves, with #1 and #2 both by the end of the third hour being one lap down to the leader. However, by the end of hour five, the #1 made back a lap and found itself 30 seconds off the lead. The #1 car's pace would pay off at the end and resulted in a fifteen-second victory over the second-place Toyota TS030 hybrid . The season would conclude with

11165-510: The #2, and the #1 being behind the #2 and the second of the Toyotas in sixth. The race got underway in hot, dry and clear conditions. As the Toyota built a lengthy lead in the first hour, both the Audi cars would make moves, passing both the Porsche 919 Hybrids . Weather would soon take its toll on a particular part of the track (turn 11) and the drivers in the second hour, and pit strategy played an important role in who would come out of

11368-464: The #7 Audi. In the third free practice, the #7 Audi was briefly on top early, but by the end a very fast lap by one of the Porsches would put it well ahead of the #7 Audi by two and a half seconds. The #8 Audi made contact with a LMP2 car during the session, damaging the car enough take it out for the remainder of the session. The car placed sixth. Qualifying would favor the Porsches, as they took

11571-510: The #7 being the better of the Audis but almost two seconds off the pace of the Porsche, which was leading at the end. The second practice session would only see one of the Audis take part, that being the #7. The #7 would place fifth overall. The #8 was receiving repairs to its front axle drivetrain. The duo of Toyotas led the way, the fastest of the two lapping over a second and a half clear of

The 2016 season began at Silverstone Circuit as it did for all the years of the FIA WEC seasons. Defending champions Porsche brought a new version of the 919 Hybrid , redesigned to be lighter to counter the regulation of electrical power and fuel capacity. The foundation of

11977-416: The #7 finished second and #8 finished third. The next round was the 6 Hours of Fuji . Audi chose to race with a revised chassis package for this race. The #7 was the fastest during the first practice and the #8 finished third fastest in the opening practice. The Porsche would rebound in the second practice, edging out the #7 Audi by about four-tenths. The #8 placed fourth. In the third practice session,

12180-427: The #7 held off both of the rival Porsches until it pitted with 3 hours and 45 minutes to go. By the end of the third hour, the #7 placed second and the #8 placed fourth. As the race was nearing the end of the fourth hour, the #7 was overtaken by one of the rival Porsches and its sister car, the #8, after trying to gamble unsuccessfully on slicks. The consequence was a pit stop to change back to wet tires, and rejoining

12383-414: The #7 in second and #8 in third with the #18 Porsche in fourth. In the last hour, the #18 Porsche made gains to get ahead of both the Audis. Both the Porsche and Audi cars would take one more stop before the race ended, and ultimately, it would determine the finishing order of the #18 Porsche and Audis #7 and #8. After the #7 and #8 pitted, the #18 would pit, and would get out the pit quicker than

12586-481: The #7 in third and the #8 in fourth. The 6 Hours of Circuit of the Americas was the next race on the calendar and the first race in North America for the season. The first free practice session was battled out at record-setting paces for both Audi and Porsche . The fastest time for a LMP1 around the track was set in the first practice session by Porsche , setting a 1:47.231 (at the time). The #8 finished

12789-428: The #7 lead the race, and the #8 was situated in fifth, five laps down. The standings with two hours and fifteen minutes to go had the #7 Audi still leading the field with a Toyota and the #18 Porsche behind it. The #8 Audi was still in fifth place, four laps down. Heading into the last hour, the #7 and #18 battled it out once again, before being separated with the Porsche pitting. With fifteen minutes to go in

12992-415: The #7 placed third and the #8 placed fourth, with the #8 spending most of the time in the garage with a gearbox issue. During the qualifying session, the #7 settled in the third slot. The #8 sat about two tenths away from the #7 car in fourth place. The race got underway in wet conditions, with the safety car leading the field when the race timer started. The track temperature was at 17 °C (63 °F) and

13195-426: The #7 reached second place, the #8 was following behind in third, and the #9 car gained two positions and was now up to fifth. The third hour would again feature the #18 Porsche and the #7 Audi setting fast laps at the front of the field. However, the #18 would start to increase its lead as the third hour continued. The #9 was in an intense battle with the #2 Toyota for fourth position. The third hour ended with

13398-400: The #7 still chasing down the #18 Porsche in second place followed by the #8 in third. The #9 was in seventh, one lap down. When hour five concluded, the #7 Audi was leading the race, with the #18 Porsche only eight seconds off the lead.

13601-429: The #7 would find itself in second place and the #8 in third. This position for both the Audis would last until the end of hour five, with the second of the Porsches racing the #8 hard to gain third. Going into the last hour is where Audi began to lose its advantage of the two podium spots it claimed, as the pace of the Porsches increased, and the second of the Porsches got second place. The race would finish with

13804-452: The #8 Toyota TS040 Hybrid had the ability to clinch the drivers' championship with a position of fifth place or better or the #2 Audi finishing lower than first place. The #2 car's driver crew was second place, and they would need a very solid finish and the #8 car to finish last in the LMP1-H standings after the race concluded. The first practice result had both of the Audi cars toward

14007-420: The #8 in fourth. Both the Audis had already taken three pit stops in contrast to both Porsche's two, using their slicks and drying line forming on the track to catch the Porsches , who were trying to conserve their wet tires over the race session. The standings would stay this way until the end of the fifth hour, where both Audi's and Porsche's cars were all even at five pit stops, the #17 Porsche leading

14210-428: The #8 in third and the #7 in fourth. The result from the final practice would follow into the qualifying session, with the #8 and #7 placing third and fourth on the starting grid. The race was a hot one, with track temperatures at 41 °C (106 °F) and 34 °C (93 °F). From the first to the end of the third hour of the first hour, #8 and #7 remained in the same positions they started in, third and fourth. In

14413-443: The #8 placing third and the #7 placing fourth on the grid for the race. The #8 was about seven and a half tenths off the leading Porsche's time.

As of these two practices, the Porsche 919 Hybrid's finished leading both sessions by the end. The third practice, however, would be dry, and that's when Audi took advantage of a faster racetrack. The #7 ended the third practice on top with a 1-minute a.nd 57.368 second lap time. The #8 car

14819-399: The #9 qualified eighth. On race day, the rain held up to a temperature of 13 °C (55 °F), and out the rolling start formation, the positioning of the LMP1-H field changed quickly. The #7 Audi would get as high as third place on the first lap. The #8 would lose a position to the #2 Toyota , but soon regain the position back. Thirty minutes into the first hour, and reminiscent of

15022-512: The 125cc race of the 2008 Valencian Community motorcycle Grand Prix . Koyama finished 7th. The system was later ruled illegal and thus was banned. The Lit C-1 electric motorcycle will also use a KERS as a regenerative braking system. KERS is also possible on a bicycle. The EPA , working with students from the University of Michigan, developed the hydraulic Regenerative Brake Launch Assist (RBLA) This has also been demonstrated by mounting

15225-415: The 2011 season. Use of KERS was still optional as in the 2009 season; and at the start of the 2011 season three teams chose not to use it. WilliamsF1 developed their own flywheel-based KERS system but decided not to use it in their F1 cars due to packaging issues, and have instead developed their own electrical KERS system. However, they set up Williams Hybrid Power to sell their developments. In 2012 it

15428-540: The 2015 season. Audi would have to compete with one more new competitor in Nissan Motorsports , who, after months of delay, had brought a trio of LMP1-H cars. However, they would prove to be largely ineffective at challenging any of the LMP1 field, due to a failed hybrid system. The #9 car in testing set the fastest lap of all the Audi prototypes during the first test day of a 3-minute and 22.307-second lap to be on pace for second place, three tenths off

15631-822: The 2015–2019 first-generation ruleset were the Ginetta-Juno P3 , Ligier JS P3 , Norma M30 , ADESS-03 , and the Ave-Riley AR-02. The cars were eligible in a number of series, such as the Asian Le Mans Series, the European Le Mans Series, as well as the V de V Endurance Series and the IMSA Prototype Challenge . A number of championships for the class have also been created, such as the FRD LMP3 series and

15834-427: The 2016 R18 had also been changed from a flywheel system to a lithium-ion battery , and had been upgraded from the 4  MJ class to the 6  MJ class for additional boost. The engine remained the same 4.0 L turbodiesel V6. Audi dropped the e-tron quattro name badge for the 2016 season. Audi raced two R18s all across the 2016 WEC season. They finished first at Silverstone; however, an irregularity concerning

16037-444: The 4 MJ hybrid output class from the 2 MJ. Although the 2015-spec car is a car that resembles the previous year's model, the aerodynamics been altered. The new aerodynamic package allowed for airflow through and around the front end, through the side panels, and at the rear of the car with the diffuser. The monocoque remains unchanged from last year, but except for a modified sidepod airflow with new radiator configurations in

16240-818: The British LMP3 Cup. First-generation cars were powered by a 5.0-litre normally-aspirated Nissan VK50 V8 engine , producing 310 kW (420 hp). A 2nd Generation ruleset was introduced for 2020, with new cars introduced: the Ginetta G61-LT-P3 , Ligier JS P320 , Duqueine D-08 , and the ADESS-03 Evo. These cars can be built from its predecessors using an upgrade kit. The new LMP3 prototypes are used in Asian Le Mans Series, Michelin Le Mans Cup , IMSA VP Racing SportsCar Challenge , European Le Mans Series, and Prototype Cup Germany. For

16443-510: The FIA World Endurance Championship (WEC) and in the 24 Hours of Le Mans from the 2021 season . Non-hybrid LMP1 cars were eligible to be "grandfathered" for two more seasons and compete alongside the new class for the 2021 to 2022 seasons. Starting from the 2023 season of WEC and IMSA SportsCar Championship, Le Mans Hypercars are joined by Le Mans Daytona h (LMDh) cars. These two kinds of prototypes will form

16646-632: The GT class regulations, forcing the ACO to promote them as prototypes. In 2000, changes were made to the LMP regulations, as the ACO once again split the open-cockpit LMP class. The two new classes became known as "LMP900" and "LMP675", with the numbers denoting the minimum weight requirements (in kilograms) for each class. The LMP900s were to be more powerful and faster in top speed, but also heavier and more cumbersome. The LMP675s were to be smaller and more nimble, yet lack

16849-519: The Group C cars with Le Mans Prototypes . Two classes were created, with LMP1s running large displacement custom-built engines that were usually turbocharged, and LMP2s using the smaller displacement production-based engines. Both classes were required to have open cockpits. However, LMP1 cars that year were just former Group C cars, some still with closed cockpits ( Toyota 94C-V , Courage C32 , Kremer K8 Spyder , Porsche 962C GTI , ALD C289 and Alpa LM). At

17052-741: The Hypercar category, a single aero kit has been made mandatory across the whole season and is limited to the Le Mans specification in the WEC; the ELMS teams have retained the right to switch between the aero kits. LMP3 is an entry-level prototype class intended for introducing young drivers and new teams to endurance racing before they progress to the higher classes of prototype racing, LMP2 and ultimately Hypercar. LMP3 uses closed-cockpit chassis, which can be built by any licensed constructor. Cars eligible for

17255-596: The LMP2 and a new class—Hypercar. In the original version of the new ruleset, revealed in November 2020, only the power of the Gibson engine has been reduced—to 560 bhp. Right before the start of the season, the cars were further weakened, by trimming an additional 20 bhp to a total of 540 bhp. The minimum weight of the cars has also been increased by 20 kg and has been set at 950 kg. Furthermore, mirroring

17458-402: The R18 did not enter the 2011 12 Hours of Sebring ; however, two evolved R18s (chassis numbers 101 and 102) were tested. In the 2011 24 Hours of Le Mans , Allan McNish (car #3) and Mike Rockenfeller 's (#1) cars were involved in collisions. The remaining Audi R18 (#2 of Marcel Fässler , André Lotterer and Benoît Tréluyer ) went on to win the race by 13.854 seconds. This was the 11th win in

17661-504: The R18 ultra, with a 500 kJ flywheel accumulator system designed by Williams Hybrid Power , two 74 kW; 100 hp (101 PS) Bosch Motor Generator Units driving the front wheels with water-cooled integrated power electronics, providing the car with four wheel drive (quattro), and a smaller 58-litre fuel tank.

17864-513: The Spaniard Marc Gené , Oliver Jarvis , and young Brazilian Lucas Di Grassi . The car would be only eligible to earn manufacturer points in Le Mans. Audi determined to use this car for its Le Mans effort, using the race at Spa as a test bed for both the #3 car and team. A damp practice session would be dominated by the e-tron quattro's and would continue into the dry qualifying session, with cars #1, #3, and #2 (in that order) qualifying

18067-579: The Tokachi 24-Hour endurance race in July 2007. This Supra became the first hybrid car in the history of motorsport to win such a race. At the NAIAS 2011 , Porsche unveiled a RSR variant of their Porsche 918 concept car which uses a flywheel-based KERS that sits beside the driver in the passenger compartment and boosts the dual electric motors driving the front wheels and the 565 BHP V8 gasoline engine driving

18270-540: The Ultra finishing in third and fifth. The leading car covered 5151.8 km, making 33 pit stops. Audi intended to run one of each model for the remaining five races in the season. Audi has instead run two e-tron Quattros since Bahrain . The 2013 season would see Audi utilize the hybrid system completely; retiring the non-hybrid turbodiesel R18 Ultra. The #1 car would be piloted by André Lotterer , Benoît Tréluyer , and Marcel Fässler . The #2 entry would be raced by Tom Kristensen , Allan McNish , and Loïc Duval . Round 1

Meanwhile, the #7 Audi would suffer from floor damage after running over a curb, resulting in a visit to the garage. The car would drop in the order to seventeenth overall. At the conclusion of the third hour, the #7 would move up to fourteenth place, but continued to lose laps after a pit stop to clean

19488-415: The car. More than ever, the new R18 directs airflow more efficiently to the underfloor to escape via the rear diffuser, which helps create a downforce to assist the car in cornering. The monocoque is 4,560 millimeters in length (which is the maximum length per the regulations). The regulations also called for larger openings in the front wheel arches to keep the car grounded. The high torsional stiffness of

19691-677: The car. As of 2023, there are two classes within Le Mans Prototypes, designated LMP2 and LMP3 . While not as fast as open-wheel Formula One cars around a track, the LMP1s were the fastest closed-wheel racing cars used in circuit racing. Le Mans Prototypes are considered a class above production-based grand tourer cars, which compete alongside them in sports car racing . Later, LMP1 designs included hybrid cars that use electric motors to assist acceleration. The Le Mans Prototype LMP1 class has been replaced by Le Mans Hypercars in

19894-474: The car. Finally, there are numerous smaller upgrades to vision and ergonomics to improve drivability. On 29 November 2015, Audi Sport debuted the redesigned R18 that the team planned to race in the 2016 FIA World Endurance Championship season. The new R18 featured significantly altered aerodynamics, including a raised nose similar to pre-2014 Formula One nose designs, air scoops above the front fenders, integrated mirrors, and other body modifications.

20300-401: The cars in the race pitted, the battle between the two resumed for the overall lead. The battle would continue to rage on throughout the race, with clean and professional racing between the two rival prototypes and back markers along the way. While the battle between the #7 and #18 continued, the #8 gained time on the two upfront as it aimed to get back on the lead lap. By the end of hour four,

20503-470: The chassis build has been built around the drive shaft for the hybrid system, with new mounting points for the front wishbone suspension . The spring damper elements are activated through pushrods at the front and pull rods at the rear. The transmission was optimized to be a lighter, six-speed gear unit. The car uses a high-pressure central hydraulics system to reduce weight while still actuating braking, transmission, and engine operations. The vehicle weight

20706-479: The chassis was carried over from 2015, with a few revised aerodynamic changes. Coming of the rather flat 2015 season that saw the defending champs uncompetitive to the likes of their German rivals, Toyota came with a brand new model, the TS050 Hybrid , which most notable change was the implementation of a smaller 2.4 liter, twin-turbocharged V6 engine. The powerplant of the hybrid system was also of note, as

20909-569: The classic Can-Am (CA) name for their prototypes. Since 2004, most series have switched to referring to these cars as Le Mans Prototypes . The American Le Mans Series , the successor to the IMSA GT Championship and the predecessor of the TUDOR United SportsCar Championship, officially referred to the cars simply as Prototypes (P1, P2, or PC). An LMP is commonly referred to as a Le Mans car in

21112-504: The competition presented by Toyota and their brand new car, the TS040 Hybrid , and Audi's sister company Porsche returned to prototype racing with the 919 Hybrid prototype racer. For practice one, Audi respectively sat in second and fourth, but by the second practice session the #1 and #2 car led the entire field, with the #1 ahead of the #2 by four-tenths flat and the #2 ahead of the nearest competitor by five-tenths. However, by

21315-538: The costs, FIA introduced a new set of LMP2 regulations, which will be locked in through 2020, aiming for a significant power increase, to the range of 150 horsepower (which is expected to lead to a four-second decrease in lap time at Le Mans). Gibson Technology is the exclusive engine supplier for LMP2, producing a four-litre normally-aspirated V8. Biofuels , specifically petrol with 10% ethanol and biodiesel ( BTL ), are allowed in both LMP1 and LMP2 categories. The fuel tank size and minimum weight for non-hybrid cars

21518-405: The ducts to prevent overheating after a piece of rubber clogged a portion of the air duct. By the end of the fourth hour, the #8 would drop a lap to the leading #5 Toyota , but remain in second place. The #7 Audi would move up to seventh overall, seven laps down. The race would have a completely different look by the end of the fifth hour that would favor Audi . The #8 would gain the lead with

21721-445: The eleventh hour, the gap between the #19 Porsche and #7 would come down after the #19 Porsche pitted and by lap 161, they were nose to tail.

A win at Le Mans placed Audi in prime position to overtake Toyota in Austin, at the 6 hours of Circuit of the Americas . The first practice session took place in overcast and cool weather. The #2 finished

22127-420: The end of qualifying practice the #1 and #2 were in the same places that they finished by the end of the first practice, the #1 in second and the #2 in fourth. The rainy weather would play a significant role in the result of the race, and it did not favor Audi . Di Grassi 's #1 lost traction and crashed in the first hour while leading the race at Woodcote, resulting in suspension damage that would be terminal to

22330-415: The end of the field. The #7 and #8 finished off the hour second and third. During the second hour, Audi's decision to race on intermediate tires, resulted in an extra pit stop over the run to the end of the second hour, placing the #8 Audi in third and the #7 Audi in fourth. The #18 Porsche was able to reclaim its starting position rather quickly. By the end of the third hour, the #7 sat in seventh and

22533-407: The end of the first hour. This positioning would last until the end of the third hour, until a brake disc failure knocked the leading Audi #8 out of first place in eighth place. When the car returned to the track, it was eight laps down on the leader, which happened to be the #7 Audi , which was threatening for the drivers' title. Meanwhile, the #17 Porsche was up to fifth place, two laps behind

22736-420: The fastest Audi being the #7 setting a lap in the 3 minute and 19 second range. The pace would significantly decrease for qualifying practice two, as the #7 Audi set a lap of a 3-minute and 20.561-second lap to place second behind the leading Porsche by a difference of 1 second and sixth tenths. The #8 and #9 would place fifth and sixth. For the final qualifying practice, two of the Audis were able to top

With the pole position at Bahrain, Porsche earned pole position spots for each for each round of the championship. The #7 finished

23751-468: The first driver to take pole position with a KERS car, his teammate, Heikki Kovalainen qualifying second. This was also the first instance of an all KERS front row. On August 30, 2009, Kimi Räikkönen won the Belgian Grand Prix with his KERS equipped Ferrari. It was the first time that KERS contributed directly to a race victory, with second placed Giancarlo Fisichella claiming "Actually, I

23954-473: The first hour it was very close amongst Audi and its rivals Toyota and Porsche . By the end of the first hour, the #2 and #1 stood in the middle of the LMP1 fray, third and fourth respectively, with the #3 car hanging onto sixth position. During hour two, rivals Toyota leaped two positions to take fourth and third away from the Audis . The #1 car also passed the #2. By the end of hour two cars #1, #2, and #3 stood in positions fourth, fifth, and sixth. By

24157-453: The first hour, the #7 was in fourth and the #8 was in fifth. During the second hour, the #8 car sustained rear chassis damage from a GTE AM car, which resulted in a lost lap in the pits for repair, dropping from third place to fifth. With four hours and twenty-six minutes to go, the #7 and the rival leading Porsche #18 were battling for overall lead of the race. The battle was briefly halted by both cars pitting in for service, but after all

24360-468: The first hour, the #7, #8, #9 were able to get by the #19 Porsche that started third. Twenty minutes into the race, with the aid of slower cars, the #8 and #7 were both able to reach the second place #18 Porsche and challenge for the position. Meanwhile, the #9 fell behind the #19 Porsche . By the end of the first hour, Audi had positions third through fifth, and all top six runners were separated by no more than eight seconds. A safety car came out at

Now holding the manufacturers lead, Audi hoped to continue the success and fight it showed in Austin . The first two practice sessions got

25375-422: The first two practices. Porsche did not waste any time setting pace within the qualifying session, with both cars times being in the low 1:36 range. Audi could only manage laps in the 1:37 range and just as the third practice, the #8 was third and the #7 was fourth. The race day was hot and humid, with a track temperatures of 37 °C (99 °F) and air temperatures of 29 °C (84 °F). The start of

25578-420: The fourth hour, the #8 went to second place briefly before a pit stop infringement pushed the car back to fourth, and the #7 car was promoted to second by the end of the fourth hour. At the end of the fifth hour, the #8 and #7 were in third and fourth, but were down a lap off the lead Porsches . In the last hour, the #7 passed the #8 and a garage visit by one of the Porsches moved both Audis up one position and

25781-451: The front axle of the car. A flywheel capable of storing over 600 kJ of energy would be inside the car as well. An ERS-K (to store kinetic energy) and ERS-H (to store energy generated from heat) would also be included within the platform of the electric turbocharged engine. As for the aerodynamics, Audi switched the chassis constructor from Dallara to YCOM. The car became smaller in width and taller in height. The newly built monocoque

25984-401: The grid for the race. The best lap for each car during each of the qualifying sessions would average to determine each car's starting position. In the first qualifying practice, the Porsches locked out the top three positions, with the best Porsche , #18 setting a 3-minute and 16.887 lap. All the Audi prototypes would be seconds back off the pace, sitting in positions fourth through sixth,

26187-472: The last hour, the last pit stop for the Audi brought its advantage over Porsche to seven seconds. With the aid of lap traffic, the Audi was able to keep the lead. A late pit stop by the #2 Porsche sealed the race victory for Audi. However, the celebration for Audi would be short lived, due to a post-race scrutineering infringement, with the thickness of the skid block not complying with the regulations. With

26390-432: The last practice, Porsche led. For the qualifying session, Audi found themselves at the back of the hybrid starting grid, the #1 being fifth place and #2 sitting in sixth. The start of the race would be dry and in comparison to the previous practices and qualifying sessions, there would not be rain in the forecast for the remainder of the six-hour session. The first hour would see both the Audis be very competitive, with

26593-440: The last round, the #7 Audi and #18 Porsche battled again, this time for second place up to this point in the race. However, a mistake by the #7 sent the car spinning at the bus stop chicane, dropping the #7 to fourth place behind the #8. The #9 car would be in seventh place. This was how the positioning for first hour would end for the Audis . By the end of the second hour, Audi would press on and promote their positions, as

26796-423: The late 2000s. Peugeot was the first manufacturer to unveil a fully functioning LMP1 car in the form of the 908 HY at the 2008 Autosport 1000 km race at Silverstone.

32480-425: The retirement of the #8 car during the event and the exclusion of the #7 with the failure to comply to regulations, Audi would receive one point (from winning pole position) for Silverstone and would sit last in the manufacturer standings below Porsche and Toyota . Spa-Francorchamps would be the second race on the calendar . At the end of the first free practice, the Audi prototypes were placed fourth and sixth,

32683-456: The same class structure as the 24 Hours of Le Mans, meaning it was the first championship to use the LMP name. At the same time, the ACO greatly altered their LMP classes. The smaller LMP2 class were briefly eliminated, while a new class of closed-cockpit prototypes was allowed in, known as "LMGTP" (Le Mans grand touring prototype). These cars were evolutions of production-based road cars that the ACO considered too advanced and too fast to fall under

32886-422: The same time, the IMSA GT Championship announced the end of their closed cockpit GTP and Lights classes, deciding as well to replace them with a single open-cockpit class of World Sports Cars equivalent to LMP1. This formula continued up to 1996, with many manufacturers embracing the LMP and WSC classes, including Ferrari , Porsche , and Mazda . In 1997, the first European series based around Le Mans Prototypes

The championship would stay in Asia for

35525-507: The top class of endurance racing: Hypercar in WEC and Grand Touring Prototype (GTP) in IMSA. Le Mans Prototypes have used various names depending on the series in which they compete. The FIA 's equivalent cars were referred to as Sports Racers (SR) or Sports Racing Prototypes (SRP). The American IMSA GT Championship termed their cars World Sports Cars (WSC), while the short-lived United States Road Racing Championship (USRRC) used

35728-404: The top of the car and between the wheel well outlets. This, in turn, enters the cooling ducts through the body hull and travels to the underfloor. To avoid vortices and turbulent airflow, which creates a loss of energy in the airflow (an increase in air resistance), Audi created a smaller monocoque space within the chassis structure, to allow high energy air to flow with ease through the chassis of

35931-535: The top speed of the larger class. Both classes were intended to be able to compete for overall wins. Audi , Chrysler , Cadillac , and Panoz opted to use the LMP900 formula, while MG were the only major manufacturer to attempt the LMP675 class. The LMGTP class also continued, with Bentley being the only manufacturer to build a closed-cockpit prototype after the regulation changes in 2000. In 2017, in order to limit

36134-543: The top two positions. The #1 Porsche would have the best lap time of the weekend, setting a 1:55.691.

By the end of the thirteenth hour, four cars were on the lead lap, and that included the #7 in second and #9 in third. In the sixteenth hour, on the run to the Ford Chicane, the #7 lost its engine cover, and by

37149-400: The two Audis in the first two positions. The #8 and #7 placed in third and fourth, with the first Audi about eight tenths off the lead. In the final practice, The results from the second practice still held for the manufacturer positioning, except the #7 finished the practice ahead of the #8 in third place. Qualifying had much of the same result seen in the last two practice sessions, with

37352-403: The two ran much of the race in the same lap until the latter stages when the #3 car fell behind pace of the #2 and made contact with another car, causing a lengthy final pit stop for nose repair (besides the refuel). The #1 of the 2011 Le Mans-winning team finished 16th overall and 5th among WEC LMP1 competitors (310); the car was less reliable than the other two, marred by a gearbox issue midway in

37555-613: The underbody of the winning car resulted in post-race disqualification; Audi decided not to dispute this decision. They won at Spa-Francorchamps and Bahrain, and finished third at Le Mans. They finished second in the Manufacturers' Championship. The R18 TDI made its race debut at the 2011 1000 km of Spa round of the Intercontinental Le Mans Cup in May, finishing 3rd. Due to developmental and logistic reasons,

37758-545: The vehicle, coupled to a 60,000 rpm flywheel. Audi and Toyota both developed LMP1 cars with kinetic energy recovery systems for the 2012 and 2013 24 Hours of Le Mans. The Audi R18 e-tron quattro uses a flywheel -based system, while the Toyota TS030 Hybrid uses a supercapacitor -based system. When Porsche announced its return to Le Mans in 2014, it also unveiled an LMP1 car with a kinetic energy recovery system. The Porsche 919 Hybrid , introduced in 2014, uses

37961-417: The weather, and in turn Toyota passed it and led until the race was stopped and called. However, the #2 car would finish third. The championship would then visit China for the 6 hours of Shanghai . The practice sessions would be very competitive, and although the Audi prototypes lead both practices, they were being closely matched for pace by Toyota . In qualifying, the #1 car would settle for second and

38164-446: Was subject to adjustment to reduce the difference in performance between hybrid and non-hybrid cars. There were no limits on the number of cylinders for any type of engine. Bodywork was required to cover all mechanical elements of the car, so that they couldn't be visible when the car is viewed directly from the front, side, or top. The LMP1 cars were generally the most powerful, with higher straight-line speeds. The LMP1 category

38367-414: Was announced that Freescale Semiconductor would collaborate with McLaren Electronic Systems to further develop its KERS for McLaren's Formula One cars from 2010 onwards.

Consequently, they clashed, however, the Audi #7 was able to stay the course and not lose too much time, gaining a position to second place while the Porsche fell behind to

40194-499: Was quicker than Kimi. He only took me because of KERS at the beginning". Although KERS was still legal in F1 in the 2010 season, all the teams had agreed not to use it. New rules for the 2011 F1 season which raised the minimum weight limit of the car and driver by 20 kg to 640 kg, along with the FOTA teams agreeing to the use of KERS devices once more, meant that KERS returned for

40397-429: Was retired at the end of the 2020 season, replaced by a new top class of the endurance racing: Hypercar . From 2017, in order to limit the costs, FIA introduced a new set of regulations, which will be locked in through 2025. The rules allow a significant power increase (150 horsepower) which is expected to lead to a four-second decrease in lap time at Le Mans. Gibson Technology is the exclusive engine supplier, producing
