61-604: The European Formula 5000 Championship was a motor racing series for Formula 5000 cars held annually from 1969 to 1975. It was organized in the United Kingdom by the British Racing and Sports Car Club with each championship also including rounds held at European circuits. The championship was first run in 1969 as the Guards Formula 5000 Championship. Various sponsorship and name changes followed, with

122-569: A collision with Jim Clark 's Lotus sent von Trips' car airborne and into the barriers at the approach to the Parabolica. Although the accident did not occur on the oval section of the track, the high speeds were deemed unsafe and F1 use of the oval was ended. Another attempt was made to use the combined circuit for the 1963 race, but the extremely bumpy nature and poor overall quality of the concrete banking saw some cars suffer mechanically. The teams protested and threatened to leave unless only

183-509: A decayed state in the years since the last race, escaping demolition in the 1990s. It is used once a year for the Monza Rally, which served part of the 2021 World Rally Championship , which was the first FIA championship event since 1969. The banked oval was used several times for record breaking until the late 1960s, although the severe bumping was a major suspension and tyre test for the production cars attempting endurance records, such as

244-591: A driver up for an overtaking move into Variante Ascari . The downhill straight down to Variante Ascari is very bumpy under the bridge. Variante Ascari is a very tricky sequence of corners and is key to the lap time. The final challenge is the Curva Parabolica Alboreto : approaching at 335 km/h (208 mph) in eighth gear, cars quickly dance around the corner, apexing in sixth gear at 229 km/h (142 mph) and exiting in sixth gear at 285 km/h (177 mph), accelerating onto

305-487: A new lap record of 1:41.745 and his speed was captured at more than 330 km/h (210 mph). In late 2016, work was planned on a new first bend, which would have bypassed the first chicane and the Curva Grande. Drivers were to go through a fast right hand kink and into a new, faster chicane. Work was planned for to be completed by 2017 in hopes of a renewed contract for Formula 1. Gravel would have also returned to

366-602: A popular historic category in Australia and New Zealand with the Tasman Revival Series running races in both countries. The S5000 Australian Drivers' Championship is marketed as a modern interpretation of Formula 5000, featuring a modern European-built open wheeler chassis fitted with a large-capacity V8 engine. The South African Formula One Championship was opened to Formula 5000 cars in 1968, with these racing against Formula One and Formula Two cars until

427-573: A significant number of continental drivers. The weak pound (a result of the energy crisis) and the increasing cost of importing Chevrolet V8 engines caused some concern and engine regulations for European F5000 were revised to permit engines other than the 5.0 litre pushrod V8s - the DOHC Cosworth GA V6 (based on a unit used in Group 2 Capris was permitted to race at a capacity of 3500cc. March 75A and Chevron B30 cars were successful with

488-613: A tribute to Formula 5000 in 2008. At that time, the Wine Country Classic was a sister event to the popular Monterey Historic Automobile Races held at Mazda Raceway Laguna Seca in Monterey, California . In 2014, the Rolex Monterey Reunion featured Formula 5000 cars as a featured race to conclude the weekend and the 2015 get together included Formula 5000 cars as well. 1971 SCCA Formula A Champion

549-410: Is blind, entered at 273 km/h (170 mph) in sixth gear, apexing at 217 km/h (135 mph), and has a slight banking. The second is a seventh gear entry at 278 km/h (173 mph), apexing in fifth gear at 203.5 km/h (126.4 mph), and it is very important that all the kerb is used. A mistake at one of these corners will result in a spin into the gravel, while good exits can set

610-470: Is just under the bridge. The kerbs are brutal and it is very easy for a car to become unbalanced and a driver to lose control, as Kimi Räikkönen did in 2005. This chicane is probably the best overtaking chance on the lap, as it is the only one with the "slow corner, long straight, slow corner"; one of the characteristics of modern circuits. The Curve di Lesmo are two corners that are not as fast as they used to be, but are still challenging corners. The first

671-610: Is the scene of many first-lap accidents. Higher kerbs were installed at the first two chicanes in 2009 to prevent cutting. Good traction out of the first corner is imperative for a quick lap. Conservation of speed through the first chicane is made possible by driving the straightest line, as a small mistake here can result in a lot of time being lost through the Curva Grande down to the Variante della Roggia chicane in eighth gear, at 330 km/h (210 mph). The braking point

732-550: The 2006 Italian Grand Prix or Nico Rosberg in the 2015 Italian Grand Prix . Drivers are on full throttle for most of the lap due to its long straights and fast corners, and is usually the scenario in which the open-wheeled Formula One cars show the raw speed of which they are capable: 372 km/h (231 mph) during the mid-2000s V10 engine formula, although in 2012 with the 2.4L V8 engines , top speeds in Formula One rarely reached over 340 km/h (210 mph);

793-639: The Blancpain GT Series Endurance Cup , International GT Open and Euroformula Open Championship , as well as various local championships such as the TCR Italian Series , Italian GT Championship , Porsche Carrera Cup Italia and Italian F4 Championship , as well as the Monza Rally Show . In 2020, Monza hosted the 2020 World Rally Championship final round, ACI Rally Monza , with the circuit hosting 10 of

854-539: The Ford Corsair GT which in 1964 captured 13 records. Both car and Grand Prix motorcycle racing were regular attractions at Monza. These races involved drivers constantly slipstreaming competing cars, which produced several close finishes, such as in 1967 , 1969 , and 1971 . As the speed of the machines increased, two chicanes were added in 1972 to reduce racing speeds – the Variante del Rettifilo at

915-652: The IMSA GT Championship in 1981, the old F5000 were now clumsy and slow compared to the new cars . In the UK, the arrival of the Cosworth DFV engine meant that many teams could now afford to build their own chassis around a good engine/transmission package, so Cooper , Lotus and Brabham stopped the production of customer Formula 1 cars. Unfortunately, smaller privateer teams and drivers that entered Britain's non-championship F1 events were left behind, and

976-688: The RAC quickly adopted the American F5000 regulations. A European championship was first run in 1969 as the Guards Formula 5000 Championship. This was renamed to Guards European Formula 5000 Championship in 1970, to Rothmans European Formula 5000 Championship in 1971 and then to ShellSport European Formula 5000 Championship in 1975. Unlike the American series, the European championship didn't attract many star names from Formula 1 and sports cars, and

1037-539: The Variante Ascari and the Curva Alboreto (formerly Curva Parabolica ). The high speed curve, Curva Grande, is located after the Variante del Rettifilo which is located at the end of the front straight or Rettifilo Tribune , and is usually taken flat out by Formula One cars. In addition to Formula One, the circuit previously hosted the 1,000 km Monza , an endurance sports car race held as part of

1098-561: The Vialone was remade in 1974, the other, Curva Grande in 1976, and a third also added in 1976 before the Lesmo , with extended run-off areas. The Grand Prix lap after these alterations was increased to 5.800 km (3.604 mi) long. With technology still increasing vehicle speeds the track was modified again in 1979 with added safety measures such as new kerbs, extended run-off areas and tyre-barriers to improve safety for drivers off

1159-675: The World Sportscar Championship and the Le Mans Series . Monza also featured the unique Race of Two Worlds events, which attempted to run Formula One and USAC National Championship cars against each other. The racetrack also previously held rounds of the Grand Prix motorcycle racing ( Italian motorcycle Grand Prix ), WTCC , TCR International Series , Superbike World Championship , Formula Renault 3.5 Series and Auto GP . Monza currently hosts rounds of

1220-483: The 1.6L turbocharged hybrid V6 engine , reduced- downforce formula of 2014 displayed top speeds of up to 360 km/h (220 mph). The circuit is generally flat, but has a gradual gradient from the second Lesmos to the Variante Ascari. Due to the low aerodynamic profile needed, with its resulting low downforce , the grip is very low; understeer is a more serious issue than at other circuits; however,

1281-522: The 16 rally stages. Monza also hosts cycling and running events, most notably the Monza 12h Cycling Marathon and Monza 21 Half Marathon. The venue was also selected by Nike scientists for the Breaking2 event, where three runners attempted to break the 2-hour barrier for the marathon . Eliud Kipchoge ran 2:00:25. A very fast circuit, Monza has been the site of many fatal accidents , especially in

1342-829: The 1970s Formula One had become more commercial and the Grand Prix stars no longer took part. The Tasman Series had become a competitive Australian/New Zealand local championship leaving the field to be dominated by the cream of "Down Under" drivers such as Frank Matich , Frank Gardner , Kevin Bartlett , Vern Schuppan , Graeme McRae , Graeme Lawrence , Warwick Brown , Johnnie Walker , John McCormack , Alan Jones , John Goss , Larry Perkins , John Bowe and Garrie Cooper racing against European and American drivers such as David Hobbs , Teddy Pilette , Mike Hailwood , Sam Posey , Richard Attwood and Peter Gethin . The four Australian Formula 5000 Tasman races continued (separate from

1403-717: The F1 calendar to ensure the lowest level of drag on the straights. There are only 6 corner complexes at Monza: the first two chicanes, the two Lesmos , the Ascari complex and the Parabolica . Thus cars are set up for maximum performance on the straights. Cars approach the first corner at 340 km/h (210 mph) in eighth gear, and brake at about 120 m (130 yd) before the first chicane—the Variante del Rettifilo —entering at 86 km/h (53 mph) in second gear, and exiting at 72 km/h (45 mph) in second gear. This

1464-625: The Italian Grand Prix was not held again until 1931; in the meantime the 1930 Monza Grand Prix was held on the high speed ring only, while in 1930 Vincenzo Florio introduced the Florio Circuit. The 1933 Italian Grand Prix was held on the original complete layout but it was marred by the deaths of three drivers ( Giuseppe Campari , Baconin Borzacchini and Stanisław Czaykowski ) in the supporting Monza Grand Prix held on

1525-578: The Milan Automobile Club – which created the Società Incremento Automobilismo e Sport (SIAS) (English: Motoring and Sport Encouragement Company ) to run the track. The initial form was a 3.4 square kilometres (1.31 sq mi) site with 10.000 km (6.214 mi) of macadamised road – comprising a 4.490 km (2.790 mi) loop track, and a 5.500 km (3.418 mi) road track. The track

1586-767: The New Zealand races) as the Rothmans International Series from 1976 until 1979. Formula 5000 was also the main component of Australian Formula 1 from 1971 to 1981 and this formula was the primary category contesting the Australian Drivers' Championship during those years and the Australian Grand Prix until 1980. Although still called Australian Formula 1 until 1983, F5000 was replaced by Formula Pacific and Formula Mondial after 1981. While European cars such as

1647-700: The V6, the March in particular being little more than a 751 Formula One car with minor modifications for the new engine. However, the same problem that befell US F5000 happened in Europe, and in 1976 the European F5000 Championship evolved into the Shellsport Group 8 Championship. This was a British-based series for Formula 1 , Formula 2 , Formula 5000 and Formula Atlantic cars, forming

1708-703: The basis of what would become the Aurora F1 Championship in 1978. The F1 Championship was open to Formula 1 and Formula 2 cars only, with Formula 5000 cars no longer eligible. Older F5000 cars continued to be used in the British Sprint Championship and were common in Formula Libre races well into the 1980s. In Australia and New Zealand, the Tasman Formula, defining cars eligible for the annual Tasman Series ,

1769-595: The bumpy Monza surface, but the Maseratis' steering was badly affected by the larger-than-usual tyre size, leading to the Modena -based team withdrawal. Ecurie Ecosse's three Jaguar D-type sports cars used their Le Mans -specification tyres with no ill-effects, but since they raced at less than their practice speeds to conserve their tyres, they were completely outpaced. Two heats in 1957 were won by Jimmy Bryan in his Kuzma - Offenhauser Dean Van Lines Special , and

1830-417: The curves, with the track layout changing the next year to incorporate permanent chicanes before the banked curves – extending the track length by 100 m (110 yd). The combined circuit held its last major race in 1969 with the 1000 km of Monza, the event moving solely to the road circuit the next year; the banking has never been used again for any major races. The banking still exists, albeit in

1891-497: The deaths of Ayrton Senna and Roland Ratzenberger in 1994 at the Imola circuit , the three main long curves were "squeezed" in order to install larger gravel traps, shortening the lap to 5.770 km (3.585 mi). In 1997 the stands were reworked to expand capacity to 51,000. In 2000 , the chicane on the main straight was altered, changing from a double left-right chicane to a single right-left chicane in an attempt to reduce

1952-452: The early years of the Formula One world championship, and has claimed the lives of 52 drivers and 35 spectators. Track modifications have continuously occurred, to improve spectator safety and reduce curve speeds, but it is still criticised by the current drivers for its lack of run-off areas , most notoriously at the chicane that cuts the Variante della Roggia . The first track was built from May to July 1922 by 3,500 workers, financed by

2013-455: The end of the start/finish straight. They experience a maximum g-force of 4.50 during deceleration, and the track has many dramatic high to low speed transitions. Lewis Hamilton recorded the fastest pole position lap at Monza in 2020 , when he lapped in 1:18.887 at an average speed of 264.362 km/h (164.267 mph) – the fastest average lap speed recorded in qualifying for a World Championship event. The official race lap record for

2074-435: The few alterations it has received, and is currently the fastest track on the Formula One calendar and has been so since 1991. Monza consists of very long straights and tight chicanes, putting a premium on good braking stability and traction. The 5.793 km (3.600 mi) circuit is very hard on engines; Formula 1 engines are at full throttle for nearly 80% of the lap, with engine failures common, notably Fernando Alonso in

2135-497: The first American to win a Formula One race. The combined circuit was not used for 3 years because during the 1956 event the Ferraris and Maseratis were suffering mechanically on the banking, and the combined circuit was used again in 1960 because Ferrari's main strength that year was straight-line speed and the organizers wanted to maximise this advantage. The 1961 race saw the death of Wolfgang von Trips and fifteen spectators when

2196-599: The formula quickly lost its appeal after 1975. Older cars continued to be used in the SCCA national races, but the most competitive teams reconverted their cars with sports car bodyworks, in the resurrected Can-Am championship, starting in 1977. The formula worked initially, with a number of European drivers crossing the Atlantic to attend the SCCA-run championship, but when IMSA introduced the new GTP prototype regulations for

2257-464: The frequent accidents at the starts due to the conformation of the braking area, although it is still deemed unsafe in terms of motorcycle racing. The second chicane was also re-profiled. In the Formula 1 Grand Prix of the same year , the first to use these new chicanes, a fire marshal, Paolo Gislimberti, was killed by flying debris after a big pileup at the second chicane. In 2007, the run-off area at

2318-621: The last by Troy Ruttman in the Watson - Offenhauser John Zink Special . In 1958 Jaguar , Ferrari and Maserati teams appeared alongside the Indy roadsters, but once again the American cars dominated the event and Jim Rathmann won the three races in a Watson - Offenhauser car. Formula One used the 10.000 km (6.214 mi) high speed track in the 1955 , 1956 , 1960 and 1961 Grands Prix. Stirling Moss and Phil Hill both won twice in this period, with Hill's win at Monza making him

2379-437: The main start/finish straight. A good exit and slipstream off a fellow driver along the main straight can produce an overtaking opportunity under heavy braking into Variante del Rettifilo ; however, it is difficult to follow a leading car closely through the Parabolica as the tow will reduce downforce and cornering speed. The maximum speed recorded in a 2024 Formula One car was 357.1 km/h (221.9 mph), established at

2440-511: The middle of the start/finish straight, and the Variante Ascari . This resulted in a new circuit length of 5.755 km (3.576 mi). Grand Prix motorcycles continued to use the un-slowed road track until two serious accidents resulted in five deaths, including Renzo Pasolini and Jarno Saarinen , in 1973, and motorcycle racing did not return to Monza until 1981. The 1972 chicanes were soon seen to be ineffective at slowing cars;

2501-530: The oldest in mainland Europe . The circuit's biggest event is the Italian Grand Prix . With the exception of the 1980 running when the track was closed while undergoing refurbishment, the race has been hosted there since 1949 . The circuit is also known as "The Temple of Speed" due to its long straights and high-speed corners. Built in the Royal Villa of Monza park in a woodland setting,

2562-412: The opposite effect, oversteer , is also present in the second sector, requiring the use of a very distinctive opposite lock technique. Since both maximum power and minimal drag are keys for speed on the straights, only competitors with enough power or aerodynamic efficiency at their disposal are able to challenge for the top places. Formula One cars are set up with one of the smallest wing angles on

2623-576: The oval at the end of June in 1957 and 1958, with three 63 lap 267.67 kilometres (166.32 mi) heat races each year, races which colloquially became known as the Monzanapolis series. Concerns were raised among the European drivers that flat-out racing on the banking would be too dangerous, so ultimately only Ecurie Ecosse and Maserati represented European racing at the first running. The American teams had brought special Firestone tyres with them, reinforced to withstand high-speed running on

2684-453: The road circuit was used, which is ultimately what happened. Future Grands Prix were held on the shorter road circuit, with the banking appearing one last time in the film Grand Prix . New safety walls, rails and fences were added before the next race and the refuelling area was moved further from the track. Chicanes were added before both bankings in 1966, and another fatality in the 1968 1000 km Monza race led to run-off areas added to

2745-805: The run-off area at the Parabolica bend. However, plans for the track's change were suspended due to the track being in the historic Monza Park . Ahead of the 2024 Italian Grand Prix , the Monza Circuit underwent significant changes. This forced WEC to abandon the 6 Hours of Monza , moving it to the Imola Circuit . In addition to facility improvements, changes included a resurfacing of the entire track. Monza, throughout its long and storied history has been known for its high-speed, simplistic nature (compared to "harder" circuits such as Singapore or Monaco , which are tight, unforgiving street circuits with lots of corners) thanks to its 1920s design and

2806-500: The same day - which became known as the "Black Day of Monza" - over the shorter oval circuit and the Grand Prix layout was changed: in 1934 a short circuit with two lanes of the straight line joined by a hairpin, Curva Sud of the banking (with a double chicane) driven in the opposite direction than usual, the "Florio link" and the Curva Sud (with a small chicane). This configuration was considered too slow and in 1935 Florio Circuit

2867-490: The second chicane was changed from gravel to asphalt. The length of the track in its current configuration is 5.793 km (3.600 mi). At the 2010 Monza Superbike World Championship round , Italian rider Max Biaggi set the fastest ever motorcycle lap of Monza when he rode his Aprilia RSV4 1000 F to pole position in a time of 1:42.121. In the Superpole qualification for the 2011 race, he improved on this lap time, for

2928-941: The series run as the Guards European Formula 5000 Championship in 1970, the Rothmans F5000 European Championship in 1971 and 1972, the Rothmans 5000 European Championship in 1973 and 1974 and finally as the ShellSport 5000 European Championship in 1975. The series was replaced by the Shellsport International Series in 1976 with Formula One , Formula Two and Formula Atlantic cars also eligible to compete. Formula 5000 In its declining years in North America Formula 5000

2989-543: The series switched to Formula Atlantic from 1976 onwards. The category was revived in the late 2000s in New Zealand as an amateur historic racing category. In 2009/2010, a five round race series was held, the final round as a support race for the 2010 Australian Grand Prix in Melbourne, Australia. The annual Wine Country Classic, a historic automobile racing event held at Infineon Raceway in Sonoma, California , had

3050-453: The site has three tracks – the 5.793 km (3.600 mi) Grand Prix track, the 2.405 km (1.494 mi) Junior track, and a 4.250 km (2.641 mi) high speed oval track with steep bankings, which was left unused for decades and had been decaying until it was restored in the 2010s. The major features of the main Grand Prix track include the Curva Grande , the Curva di Lesmo ,

3111-455: The track was suspended until 1948 and parts of the circuit degraded due to the lack of maintenance and military use. Monza was renovated over a period of two months at the beginning of 1948 and a Grand Prix was held on 17 October 1948. In 1954, work began to entirely revamp the circuit, resulting in a 5.750 km (3.573 mi) course, and a new 4.250 km (2.641 mi) high-speed oval with banked sopraelevata curves (the southern one

3172-447: The track. The infrastructure was also improved, with pits able to accommodate 46 cars, and an upgraded paddock and scrutineering facilities. These changes encouraged world championship motorcycling to return in 1981, but further safety work was undertaken through the 1980s. Also in the 1980s the podium, paddock and pits complex, stands, and camp site were either rebuilt or improved. As motorsport became more safety conscious following

3233-594: The various Lolas , McLarens and Chevrons were popular, locally made cars from Matich (Matich A50, A51, A52 and A53), Elfin ( Elfin MR5 , MR6, MR8 and the MR9, the only ground effects F5000 ever built) and McRae were also successful. The most popular engine used was the 5.0 L Chevrolet V8 , with the Australian made Repco Holden , based on the 5.0 L Holden V8 engine , also popular and successful. Formula 5000 remains

Autodromo Nazionale Monza The Monza Circuit ( Italian : Autodromo Nazionale di Monza ; lit.   ' Monza National Racetrack ' ) is a 5.793 km (3.600 mi) race track near the city of Monza , north of Milan , in Italy. Built in 1922, it was the world's third purpose-built motor racing circuit after Brooklands and Indianapolis and

3355-492: Was dominated by drivers that were usually seen in Formula 2 or at the back of F1's World Championship grids. Peter Gethin managed to launch his F1 career thanks to his F5000 championship titles. While it was based in the United Kingdom, the series managed to spread across Europe, with races held at many international circuits, including Monza (Italy), Hockenheim (Germany) and Zandvoort (Netherlands), and attracted

3416-467: Was extended in 1970 to include Formula 5000 cars as well as the existing 2.5 litre cars. The Tasman Series ran during the Formula One off season in the European winter, and in the 1960s it had attracted the attention of the greatest names in Grand Prix racing, from locals Jack Brabham , Denny Hulme , Bruce McLaren and Chris Amon , to foreigners like Graham Hill , Jim Clark , Jackie Stewart , Phil Hill , Piers Courage and Jochen Rindt . However, by

3477-611: Was inspired by the success of the Can-Am Series, which featured unlimited formula sports cars fitted with very powerful engines derived from American V8s ; the idea was to replicate the concept using open wheel racing cars. F5000 enjoyed popularity in the early 1970s in the U.S. and featured drivers such as Mario Andretti , Al Unser , Bobby Unser , James Hunt , Jody Scheckter , Brian Redman , David Hobbs , Tony Adamowicz , Sam Posey , Ian Ashley , John Cannon and Eppie Wietzes . Increasing costs and Lola domination meant

3538-580: Was modified into a closed wheel, but still single-seat sports car racing category. Formula 5000 was introduced in 1968 as a class within SCCA Formula A races, a series where single seaters from different origins were allowed to compete, but which rapidly came to be dominated by the cars equipped with production-based American V8s. The engines used were generally 5 litre, fuel injected Chevrolet engines with about 500 horsepower (370 kW) at 8000 rpm, although other makes were also used. The concept

3599-594: Was moved slightly north). The two circuits could be combined to re-create the former 10 kilometres (6.214 mi) long circuit, with cars running parallel on the main straight. The first Lesmo curve was modified to be made faster, and the track infrastructure and facilities were also updated and improved to better accommodate the teams and spectators. The Automobile Club of Italy held 500 mi (800 km) Race of Two Worlds exhibition competitions, intended to pit United States Auto Club IndyCars against European Formula One and sports cars. The races were held on

3660-400: Was officially opened on 3 September 1922, with the maiden race the second Italian Grand Prix held on 10 September 1922. In 1928, the most serious Italian racing accident to date ended in the death of driver Emilio Materassi and 27 spectators at that year's Italian Grand Prix . The accident led to further Grand Prix races' confinement to the high-speed loop until 1932. For these reasons

3721-495: Was used again, this time with four temporary chicanes and another one permanent (along the Curva Sud of the banking). In 1938 only the last one was used. There was major rebuilding in 1938–39, constructing new stands and entrances, resurfacing the track, removing the high speed ring and adding two new bends on the southern part of the circuit. The resulting layout gave a Grand Prix lap of 6.300 km (3.915 mi), in use until 1954. The outbreak of World War II meant racing at
