76-554: The series was established under the Argentine Automobile Club as the "Campeonato Argentino de Velocidad" in 1937 and re-named Turismo Carretera two years later, however its' roots can be traced back to the loosely-organised Grands Prix de Carretera of the 1910s. Events were held on open roads, across asphalt and dirt surfaces, and were held as both circuit and rally-style stage races. Competitors used lightly-modified production coupés, and employed navigators due to

152-503: A 9,500km stage race from Buenos Aires to Caracas . In the 1960s, competitors began to further experiment with modifications as the coupés gave way to prototype versions of locally-made sedans; examples of such include the 1967 and 1969-winning Liebre Torinos (breaking Ford and Chevrolet's duopoly on championships) and the 1968-winning Trueno Naranja . In 1970, the championship was split into two classes – one for road races, and another for events on permanent circuits – however only for

228-708: A competitor to Championship Auto Racing Teams (CART). In 2008, the IndyCar Series merged with CART's successor, the Champ Car World Series and the history and statistics of both series, as well as those from its predecessors, were unified. The series' premier event is the Indianapolis 500 , which was first held in 1911. Historically, open-wheel racing was the most popular form of U.S. motorsport nationwide. However, an acrimonious schism (often referred to by many as "The Split") in 1994 between

304-414: A consortium of ethanol producers that advocate the increased use of ethanol . EPIC was anxious to address public concerns of that era that ethanol use led to engine damage and poor performance when used in road cars. As a marketing effort, it was believed that sponsoring an IndyCar could be used as a tool to promote education and awareness of ethanol use and to curb the spread of erroneous information. Dana

380-437: A crash at Comodoro Rivadavia led to a ban on navigators – a practice which, by that point, had largely been kept purely on the grounds of tradition. In 2008, a NASCAR-style "Chase" championship format was introduced (see below). In 2015, the category introduced modernised multi-valve engines . In the late-2010s and early-2020s, the championship was dominated by Agustín Canapino of Chevrolet and Mariano Werner of Ford ,

456-406: A first-ever Dallara DW12 facelift. The kits, while increasing speeds and offering a clear distinction between the two manufacturers, did lead to significant cost increases. Further, Chevrolet's aero kit was the more dominant with Honda only able to mount a competitive charge on ovals due to having slightly better engine power. While Honda was able to make gains in 2016, after two years of development

532-565: A foot protection bulkhead, and cockpit padding. From the 2020 season onwards, the IndyCar Series implemented a cockpit protection system. This consists of a combination of the Halo mandated in Formula One and a reinforced windscreen dubbed the "aeroscreen", provided by Red Bull Advanced Technologies, to lessen the probability of traumatic head injuries from flying debris. All IndyCar Series cars carry an Electronic Control Unit. Live telemetry

608-493: A platform for manufacturers to advertise their light commercial trucks – however, this category has resulted in the Argentine equivalent of "Buschwhacking" with Turismo Carretera regulars and former champions dominating events; in 2022, all but one of the eleven Finals were won by current or former TC drivers. Since 2008, Turismo Carretera has held a NASCAR -style "playoff" format alongside its regular championship to decide

684-429: A pneumatic clutch with semi-automatic activation, supplied by Xtrac Limited since the 2008 season. All current IndyCar transmissions use pneumatic actuation for the shifting and clutch, so the clutch is therefore only needed for launching the car from a standstill, and the clutch isn't required for gear shifting. From 1996 to 2007, all IndyCar Series cars used a hand-shifted 6-speed sequential manual transmission with

760-592: A practice crash. Riley & Scott produced IndyCar chassis from 1997 to 2000. Their initial effort, the Mark V, was introduced late in the 1997 season, severely limiting its potential market. It also proved to be uncompetitive. After Riley & Scott was purchased by Reynard, an all-new model, the Mark VII, was introduced for the 2000 season. It won in Phoenix, the second race of the season (driven by Buddy Lazier), but

836-516: A rivalry which was only broken by Canapino briefly moving to IndyCar and a title for José Manuel Urcera in 2022 – the first for a Torino in 51 years. That same year, Toyota entered the category with a modern Camry , leading to the introduction of new models based on American pony cars two years later. There are currently four tiers on the Turismo Carretera ladder. The top rung is Turismo Carretera itself, followed by TC Pista as

912-810: A set of regulations designed to create parity between the various manufacturers involved. Since the 1970s, four manufacturers have been concurrently represented in Turismo Carretera using Argentine-built models – Chevrolet with the Nova , Dodge with the GTX , Ford with the Falcon , and Industrias Kaiser Argentina with the Torino ; Toyota joined in 2022 with the Camry XV70 . The Dodge GTX and IKA Torino were originally equipped with Slant Six and Tornado engines respectively, but both moved to Chrysler Cherokee engines in

988-501: A shift stick lever, supplied also by Xtrac since 2000 season until 2007. The clutches of all IndyCar Series cars are carbon with steel housing 3-plate clutch operated by foot-pedal in 1996–2011 later hand-paddle steering wheel clutch in 2012–present and provided by AP Racing . Mechanical limited-slip differentials are also allowed and constant velocity joint tripod driveshafts are also used. All IndyCar Series car drivetrains are currently rear mid-engine with rear-wheel-drive layout . Since

1064-538: A single set of specifications is used, based upon the configuration and speed of the track, as well as having the right rear tire diameter constructed to be slightly larger than the left rear, (also known as stagger) to aid in high speed cornering. The suspension of all IndyCar Series cars is double A-arm, pushrod, with third spring and anti-roll bar configuration multilink. All NTT IndyCar Series cars use carbon-fiber shell driver's seats with 6-point safety restraints. The cars' steering wheels are designed by Cosworth with

1140-556: A system of buttons that allow the drivers to make adjustments to their cars mid-race. All IndyCar Series cars were equipped with Pi Research Sigma Wheel to Display data display units from 2001–2017 until they were replaced by Cosworth's Configurable Display Unit 4.3 display from 2018 onwards (although in 2018 some smaller low-budget IndyCar Series teams still utilized old Pi Research Sigma Wheel instead of new Cosworth Configurable Display Unit 4.3 due to cost reasons). The cockpits of all IndyCar Series cars are still open but protected by zylon,

1216-572: A universal bodywork kit. Digital renderings for the common bodywork kit, referred to as the 'IR18' car, were released in early May 2017 as a second facelift of Dallara DW12 . The car was officially unveiled in late July, and the universal aero kit became known as the UAK18 bodywork. The bodywork is inspired by CART 's 1990s and 2000s designs, with a more streamlined appearance. The redesigned aero kit reduces both aerodynamic downforce and team and manufacturer design development costs. The universal Aero Kit

1292-463: A well-funded team, was brought on to develop the engine with team owner Eddie Cheever expanding the team to two cars and bringing on his brother Ross Cheever as a test driver. By 2000, the engine had improved markedly and Cheever captured the marque's first win at Pikes Peak International Raceway . However, despite the improved success, few teams made the switch to the Infiniti and the company left

1368-775: Is used only for television broadcasts, but the data can be recorded from the ECU to the computer if the car is in the garage tents and not on the track. Since 2007 McLaren supplied its Engine Control Unit (ECU) system for few IndyCar Series teams and later promoted to standard Engine Control Unit (ECU) systems from 2010 season onwards. Previously Motorola supplied IndyCar Series ECU in 2003–2009 for Honda -powered cars, also Denso supplied IndyCar Series ECU in 2003–2005 for Toyota -powered cars and also Zytek supplied IndyCar Series ECU in 2002–2005 for Chevrolet -powered cars. Rearview mirrors for all IndyCar Series cars are fully mandated to easily enable viewing opponents behind. At its inception,

1444-566: The CART chassis and turbocharged engines that had been the mainstay of the Indianapolis 500 since the late 1970s. Starting with the 2003 season, the series rules were changed to require chassis manufacturers to be approved by the league before they could build cars. Prior to that, any interested party could build a car, provided it met the rules and was made available to customers at the league-mandated price. In total, four manufacturers have built IndyCar chassis. Dallara began producing Indycars for

1520-497: The Firestone Indy Lights machines. After the withdrawal of factory support from Panoz Auto Development , they are the only supplier of new chassis. The G Force chassis was introduced in 1997 and won the 1997 and 2000 Indy 500 races. In 2002, Élan Motorsport Technologies bought G Force, and the chassis was renamed "Panoz G Force", and then shortened to "Panoz" in 2005. In 2003 a new model was introduced, and it won

1596-653: The NTT IndyCar Series under sponsorship , is the highest class of American open-wheel car racing in the United States, which has been conducted under the auspices of various sanctioning bodies since 1920 after two initial attempts in 1905 and 1916. The series is self-sanctioned by its parent company, IndyCar, LLC ., which began in 1996 as the Indy Racing League (IRL) and was created by then Indianapolis Motor Speedway owner Tony George as

1672-591: The Oldsmobile Aurora label) and Nissan (badged as Infiniti). Per IRL rules, the engines sold for no more than $ 80,000 (with an exception of full-works IndyCar Series teams that usually received free engines due to direct partnership with an each engine manufacturer), and were rev-limited to over 10,000 rpm and weighed up to 280  lb (127  kg ) (excl. headers, clutch, ECU, spark box or filters). They produced around 600–700 hp (450–520 kW). These engines utilized 90° crankshafts , and while

1748-581: The TC2000 Championship . Héctor Gradassi and Juan María Traverso were the first to find success in the new formula – centred around Chevrolet , Ford , Dodge and IKA Torino – before a feud between the governing bodies ACA and CADAD led to the prolonging of the 1979 season and the formation of the ACTC in 1981; an independent body that runs the competition to this day. The 1980s saw the rise of Dodge through their new GTX model , claiming 8 of

1824-476: The 10 championships that decade – four of coming via Roberto Mouras . In 1989, Chevrolet and Ford were given concessions related to engine compression, putting them at a significant technical advantage to the Dodge and now-outdated IKA Torino models; this was only rectified in 1995, when competitor abandonment of the Dodge and Torino led to the homologation of Jeep Cherokee engines to keep them competitive. Following

1900-470: The 1997 season. The Dallara and G Force chassis were relatively evenly matched over their first few seasons, but eventually, the Dallara began to win more races. This caused more teams to switch to the Dallara, further increasing their success. As of 2017, a Dallara chassis has been used by 17 Indy 500 winners, although there have not been any competing manufacturers since 2008. Dallara was also tapped to build

1976-511: The 2008 Toyota Grand Prix of Long Beach . In 2010, IndyCar announced that it would officially adopt a single-make chassis formula, beginning in 2012 among a selection of proposals from interested parties, and set up the ICONIC (Innovative, Competitive, Open-Wheel, New, Industry-Relevant, Cost-Effective) Advisory Committee to make a final recommendation. Proposals were submitted and announced by BAT Engineering, Dallara , Lola , Swift , as well as

2052-763: The Heats, followed by their race position and then their race time. In addition, there can be up to four "special races" ( carreras especiales ) held in the regular season before the playoffs. In 2023, three special races were held: one with a mandatory pitstop for refueling in La Pampa , the Carrera de los Milliones in Rafaela with a special monetary prize for the winner, and the Desafío de las Estrellas in Villicum where

2128-512: The IRL used methanol racing fuel, which had been the de facto standard in American open-wheel racing since the 1964 Indianapolis 500 Eddie Sachs – Dave MacDonald crash. Methanol had long provided a safer alternative to gasoline. It had a higher flash point, was easily extinguishable with water, and burned invisible. With the IRL's introduction of night races in 1997, the burning of methanol fuel

2204-560: The IRL, a major point of contention for CART management, to whom Ford-Cosworth was an official engine supplier. The Ilmor Mercedes V-8 engine, also a mainstay CART powerplant, was permitted, but the only time it was used as a one-off at the 1996 Indy 500 by Galles Racing . Starting in 1997, IRL cars were powered by 4.0-litre V8 , four-stroke piston, Otto cycle methanol -burning, production prototype-based, naturally-aspirated internal combustion engines and electronic indirect multi-point port fuel injection, produced by General Motors (under

2280-838: The Indianapolis 500 and the series title. However, Toyota had just one podium in the last seven races of 2004, and only Penske Racing fielded competitive Toyota-powered cars in 2005, while Honda became the dominant engine manufacturer within the series. In November 2005, Toyota company officials announced the company's withdrawal from American open-wheel racing and the immediate discontinuation of its IRL program, coinciding with its entrance into NASCAR's Craftsman Truck Series in 2004, and its discontinuation of its IMSA program. After Chevrolet and Toyota elected to shut down their IRL involvement after 2005 season ( Chevrolet temporarily hiatus from IndyCar Series for six years while Toyota USA elected to focus on NASCAR involvement), Honda became

2356-556: The Indy 500 in 2003–2004 and finished second in 2005. It fell out of favor starting in 2006, and by then, only one had finished in the top ten at Indy. Little factory support was given to IndyCar teams by Panoz after that point, as they had concentrated on their DP01 chassis for the rival Champ Car World Series. By 2008, only one Panoz saw track time, an aborted second-weekend effort at Indy, that resulted in Phil Giebler being injured in

2432-489: The U.S. government's demand that the alcohol is unfit for human consumption and add visible color in case of fire. However, 2010 São Paulo Indy 300 , held in Brazil –outside of the U.S. regulations– utilized a full E100 mixture, the first instance in the sport. To compensate for the loss of power due to the use of ethanol, the displacement was increased back to 3.5 liters. Since ethanol gets better fuel mileage than methanol,

2508-498: The cars were unique, being designed specifically for oval racing; for example, the oil and cooling systems were asymmetrical to account for the pull of liquids to the right side of the cars. Later cars were designed to accommodate the added requirements of road racing. Because of a schedule conflict, the Champ Car World Series spec Panoz DP01 , with a Cosworth engine, was run in an IndyCar Series points event in

The top twelve drivers in the championship after the final round before the playoffs make the cut. All drivers start on zero points, however the championship leader will receive a bonus 15 starting points, and every driver that won an event 'Final' (see below) will receive an additional 8 starting points per win.

However, after a series of safety concerns during practice for the 2015 Indianapolis 500 with the Chevrolet aero kit package, this did not come about. The 2017 season was the third and final year contested with the Chevrolet and Honda aero kits outfitted to the Dallara DW12 chassis. Beginning in 2018, all DW12 Safety Cell chassis have been fitted with

2812-496: The engine blocks were to be production-based, they were not "stock blocks" like the Buick or Menard engines of the 1980s and 1990s. They were purpose-built racing engines. The engine formula was changed with the 2000–2004 formula. The displacement was dropped down from 4.0 to 3.5 litres (244 to 214 cubic inches ), and the requirement for the block to be production-based was dropped. The engines also switched to 180° crankshafts , and

2888-443: The engines were moderately de-tuned. The engines proved themselves to be quite durable — there had been no engine failures at Indy from 2006 to 2010, which also lowered the number of crashes. Most of the engines, including those used for the Indy 500, are used for multiple races and were intended to last 1,200 miles (1,931 kilometres ) between rebuilds. The Honda engines were only available via lease arrangement from Honda, which, for

2964-472: The existing engine blocks to curb top speeds (started from the 2004 Indianapolis 500 ). Infiniti's engines, though reliable, were significantly down on power compared to the Auroras in 1997, leading many of the teams that had initially opted for the Infiniti to switch. By the end of the 1998 season, only a handful of low-budget teams were using the Infiniti. However, early in the 1999 season, Cheever Racing ,

3040-439: The final round of the season, the top three drivers in the regular standings that did not qualify for the playoffs will be admitted along with the points they scored over the previous four rounds (two in 2020). No bonus points will be awarded to these "last chance qualifiers". Drivers that qualify for the Copa de Oro are differentiated from regular competitors by running gold numbers on the rear-passenger windows and gold paint on

3116-459: The first three positions on the grid, in order of fastest to slowest race time. This process is then followed for the rest of the grid, with the order determined by first a drivers' heat position and then their race time. Drivers who did not finish on the lead lap in their heat race will be moved to the rear of the field for the Final, and their order will be determined by how many laps they complete in

3192-451: The first time since 2011. The fuel cell for all current IndyCar Series cars are made of rubber and are covered with a Kevlar-fitted blanket for extra protection in side impacts. Since 2012 the capacity has been 18.5 US gallons (70 litres ). Previous capacities were 22 US gallons (83 litres ) in 2007–2011, 30 US gallons (114 litres ) in 2004–2006, and 35 US gallons (132 litres ) in 1997–2003. The initial 1996 IRL season, as well as

3268-451: The first two races of the 1996–97 season, featured engines with specifications leftover from the rival CART series competition. Those chassis/engine combinations were essentially under the same rules utilized by teams that participated in the 1995 Indianapolis 500 , which was sanctioned by USAC. V-8 powerplants were allowed the typical 45 inHg (1.5 bar; 22.1 psi) of pressure boost. The Menard-Buick V6 engine used in 1996, however,

The thicker steel brake rotors with 6-pot brake calipers and carbon pads were introduced in 2005 for road and street course races for stronger braking while approaching sharper turns even hairpins. From 2012 onwards, IndyCar Series ditched

3420-636: The front and 14 in × 15 in (356 mm × 381 mm) on the rear since 1996; this size will be used until at least the 2022 season. 18-inch wheel rims will be adopted if the Dallara DW12 's successor comes out for the 2023 season onward. Firestone has been a tire supplier for the series since the 1996 season and sole tire supplier since 2000 season. Previously, Goodyear also supplied tires from 1996 to 1999 for several teams before withdrawing their support. The IndyCar Series has run bespoke compounds since 1996 which were re-profiled in 2003. The front tire sizes are 305/45-R15 (10.0/25.8-R15) and

3496-485: The front undertray. In modern Turismo Carretera, there are "normal races" and "special races" in each season. The "normal races" have a format of one qualifying session (held on Saturday) and four races (held on Sunday) per weekend. The first three races – called Series (Heats) – split the field into three separate groups, which are formed from the results of qualifying. The fastest qualifier occupies first place in Heat 1,

3572-453: The fuel tanks in the car were decreased. Compared to methanol, human contact with the current ICS fuel is much less harsh, and the fumes much less irritating. The fumes are often compared with the sweet smell of apple cider or apple cobbler. Unlike methanol, ethanol is not caustic and does not cause chemical burns when it comes in contact with the skin. It also is less polluting when spilled compared to methanol. In May 2010, Sunoco became

3648-430: The grid is determined by a lottery and there are two mandatory stops to change tyres and refuel. Additionally, there is a Special Races Tournament ( Torneo de Carreras Especiales ) that gives the winner the opportunity to qualify for the playoffs if they have not made it through via their position the regular season standings. The circuits in 2023: Turismo Carretera cars are built by individual teams and constructors to

3724-480: The kits were frozen for 2017, and starting in 2018 all cars ran the same aero package again. To further help reduce costs, IndyCar allowed teams to shop for competitively priced non-safety-related parts such as brakes instead of mandating parts from specific suppliers. IndyCar had hoped to set a new speed record at the Indianapolis Motor Speedway by 2016 with the introduction of aero kits and

3800-529: The mid-1990s – the Toyota has exclusively run with a Cherokee engine since its original homologation in 2022. In 2024, the vehicles were upgraded to their modern counterparts with a focus on retaining OEM styling; the previous cars had all evolved to look very similar. Chevrolet, Dodge and Ford switched to American pony cars in the form of the Camaro , Challenger and Mustang respectively, whilst Toyota retained

3876-403: The nature of the races. Future Formula One World Champion Juan Manuel Fangio was among the first drivers to find success in the category, winning back-to-back titles in the early-1940s, before the brothers Gálvez ( Oscar and Juan ) shared fourteen out of fifteen titles in a row in the post- World War II period. The most infamous event during this time was the 1948 South American Grand Prix ,

3952-521: The official fuel of the series starting in mid-2010 with an immediate effect, running through 2018. For the 2012 season, the ethanol fuel blend rate was reduced to 85% blend in a reference of road car relevance. Speedway LLC took over as series official fuel supplier beginning from 2019 season onwards, but the E85 formula still retained until at 2022. From 2023 onwards Shell USA (North American division of Shell plc ) will supply 100% Ethanol-sourced fuel for

This chassis was intended to support multiple aerodynamic kits, but introduction of these was delayed until 2015, with teams citing costs. After the events of the 2011 IZOD IndyCar World Championships the chassis was nicknamed DW12 in honor of Dan Wheldon . In 2015, teams began running aero kits developed by their engine manufacturers as

4180-533: The primary series, CART, and Tony George led to the formation of the Indy Racing League, which launched the rival IndyCar Series in 1996. From that point on, the popularity of open wheel racing in the U.S. declined dramatically. The feud was settled in 2008 with an agreement to merge the two series under the IndyCar banner, but enormous damage had already been done to the sport. Post-merger, IndyCar continues to run with slight viewership gains per year. For 1996–1997,

On November 4, 2004, Chevrolet stated that it would be ending its IRL engine program effective with the end of the 2005 season, citing costs that exceeded value, according to then GM Racing Director Doug Duchardt, "The investment did not meet our objectives." Toyota won its first race in Miami, as well as

4332-486: The radical DeltaWing design that was penned by Ben Bowlby and financed by Chip Ganassi . In July 2010, IndyCar announced that Dallara had won the contract to remain as the series' single chassis supplier. In 2012 the series adopted the Dallara IR-12 chassis as a cost control method, and IndyCar negotiated a price of $ 349,000 per chassis. The new specification also improved safety, the most obvious feature being

4408-549: The rear tire sizes are 415/40-R15 (14.5/28.0-R15). The compounds and construction of IndyCar Series tires unique to each mounting position on the race car. For road/street events, there are unique primary and alternative specifications for dry conditions, along with specially designed full-rain tires for all rain conditions but, unlike in Formula One which has intermediate rain tires for light rain conditions only, no intermediate rain tires due to additional costs. For oval racing,

4484-422: The rev limits were adjusted from time to time. These engines made 675 hp (503 kW), ran on 109- octane methanol racing fuel, and revved to 10,300 rpm, all while weighing only 280 lb (130 kg). This formula was used through 2003. In 2004, in the wake of several crashes including the fatal crash of Tony Renna and the severe crash of Kenny Bräck , the displacement was reduced to 3.0-liters using

4560-444: The same chassis. Currently, Dallara provides a specification chassis to all teams, with Honda and Chevrolet providing teams different engines. In the series' first season ( 1996 ), 1992 to 1995 model year CART chassis built by Lola and Reynard were used. The first new Indycar came into being in 1997. Tony George specified new technical rules for less expensive cars and production-based engines. The move effectively outlawed

The fourth-fastest driver in qualifying occupies second place on the grid in Heat 1, and so on until the entire field is divided into three. Each heat race is a five-lap sprint and defines the grid positions for the final race (or Final ), usually held over 25 laps held in the afternoon. The winners of the three heats occupy

4788-550: The series after the 2002 season to focus on powering the league's new Infiniti Pro Series (now Firestone Indy Lights). As part of General Motors' discontinuance of the Oldsmobile name, the Olds engine was rebadged as the Chevrolet starting with the 2002 season. However, the effort would lack in competitiveness against Toyota and Honda, which came to the IRL in 2003 from the rival CART series. In August 2003, Chevrolet announced to

4864-512: The series to ensure future continuity. The Honda Indy V8 engine was partnered and co-developed by Ilmor , which is part owned by Roger Penske for tune-up, engine maintenance, arrangement and trackside support. The engine displacement was reverted from 3.0 to 3.5 litres (183 to 214 cubic inches ) beginning from 2007 season. During that time, since the IndyCar Series had only one engine manufacturer, Honda focused on minimizing engine failure and minimizing costs instead of defeating rivals. As such,

4940-422: The series was now legally entitled to use it due to the expiration of a 1996 legal settlement with Championship Auto Racing Teams (CART). The series began to progressively downplay the former IRL name, changing its name to simply IndyCar for the 2008 season. The company was similarly renamed in 2011. Izod signed a six-year deal to become the series title sponsor beginning on November 5, 2009, through 2014, but

5016-645: The series was simply referred to as the Indy Racing League. For 1998–1999, the series garnered its first title sponsor, and was advertised as the Pep Boys Indy Racing League . In 2000, the series sold its naming rights to Internet search engine Northern Light , and the series was named the Indy Racing Northern Light Series . The name IndyCar Series was officially adopted beginning in 2003, as

5092-447: The single season. In 1973, Nasif Estéfano became the series' first and only posthumous champion having died in a crash in the third-to-last event of the season. As the decade progressed, the prototypes were abandoned in favour of regulations that brought the series closer to its' production-based roots whilst retaining the domestically-built cars; a spin-off series for the prototypes was created, but slowly died out and later morphed into

5168-515: The sponsorship was terminated at the end of the 2013 season. In 2014, Verizon Communications became title sponsor of the series through 2018. In January 2019, it was announced that Japanese communications company NTT would become title sponsor and official technology partner of the IndyCar Series. In 2023, IndyCar announced that NTT had extended their title sponsorship, for an unreported length. The IndyCar Series allows manufacturers to develop different types of engines, while every team uses

5244-737: The steel brake discs in favor of carbon brake rotors on all types of tracks but the caliper configuration remained the same as 1996–2011. PFC currently supplying brake packages for all IndyCar Series cars since 2017 season (disc only) and later increased their involvement from the 2018 season (supplying the calipers and rest of other brake packages). Previously Brembo supplied the brake packages in 2012–2016 (full brake package), 2017 (caliper only), and Alcon in 2003–2011. BBS and O.Z. Racing have been supplying forged wheels since 1996. The wheel rims for all IndyCar Series cars are made of aluminum alloy. The size of IndyCar Series wheel rims have been 10 in × 15 in (254 mm × 381 mm) on

5320-599: The still-new Camry but redesigned the front end; a concept Torino was created as IKA went out of business in 1975.

5396-478: The track and expenses from repairs. The "aeroscreen" cockpit protection was added in time for the 2020 season, and some minor modifications were eventually conducted to reduce the intense heat caused by stagnant air on the drivers. For the transmission gearboxes, all IndyCar Series cars currently use an electronically actuated AGS ( Assisted Gearchange System ) 6-speed semi-automatic sequential gearbox with an electro-pneumatically operated paddle-shift system and

5472-611: Was an updated powerplant from the 1995 version. In addition, the V-6 stock block engines (Buick-Menard) were allowed 55 inHg (1.9 bar; 27.0 psi) of boost at all races, instead of just at Indianapolis. During the CART era, V-6 stock blocks were only allowed 45 inHg (1.5 bar; 22.1 psi) at all races outside of Indy, which was a decided disadvantage and left the engine out of favor. Ford-Cosworth reluctantly provided support to teams wishing to run their older-spec engines in

5548-470: Was designed without the wheel guards of the DW12 chassis, which were deemed ineffective and proved prone to breaking. The IR-18 also lacks an air inlet above the cockpit, a first for an IndyCar Series chassis (most Champ Car chassis had been designed that way). The new Aero Kit also has fewer small aerodynamic pieces that can become broken or dislodged, with the intent to reduce the amount of debris that ends up on

5624-431: Was killed in a crash in 2006, but the IRL had already begun a transition to ethanol fuel . For the 2006 season the fuel was a 90%/10% mixture of methanol and ethanol . Starting in 2007, the league advertised " 100% Fuel Grade Ethanol ," the first competitive series to utilize renewable fuel. The mixture was actually 98% ethanol and 2% gasoline, provided by Lifeline Foods of Saint Joseph, Missouri . The additives satisfy

5700-495: Was off the pace at Indy and was quickly dropped by its teams. Falcon Cars were founded by Michael Kranefuss and Ken Anderson in 2002 as the third approved chassis supplier for the 2003 season. One rolling chassis was completed and shown, but it was never fitted with a working engine and never ran. No orders were ever filled. Superficially, IndyCar machines closely resemble those of other open-wheeled formula racing cars, with front and rear wings and prominent airboxes . Originally,

5776-468: Was visible for the first time, seen with a light blue haze. With this in mind, in an effort to make it more visible in case of fire during daylight hours, additional mixtures were placed in the fuel. As a safety feature, the methanol would burn with color. In 2005, the driver Paul Dana brought the sponsorship of the Ethanol Promotion and Information Council (EPIC) to his IndyCar team. EPIC is
