Query: When was the Silverstone Circuit built?
Silverstone Circuit is built on the site of a World War II Royal Air Force bomber station, RAF Silverstone, which opened in 1943. The airfield's three runways, in classic WWII triangle format, lie within the outline of the present track. Since its first use in the 1940s, the circuit has undergone several changes.
1985 was to see Keke Rosberg set the all-time Formula 1 qualifying lap record for 17 years after posting fastest qualifying time for the race with an average speed of 258.983 km/h (160.92 mph). Silverstone, which was already a very fast circuit, was becoming faster and faster and the cars were lapping the circuit in the low 1-minute range. The race was an exciting one with Brazilian rising star Ayrton Senna making a great start from 4th and taking the lead by the first corner. He led until late in the race, when his car was running out of fuel while Prost was pushing him hard; Senna eventually ran out of fuel and Prost went on to take victory. 1986 saw a huge crowd thanks to Mansell being a favourite to win; his newly found fame and place in a competitive team would help the British Grand Prix to see huge crowds for several years. This race saw 42-year-old Jacques Laffite get involved in a first corner accident and slam head-on into the barriers, breaking both his legs and ending his Formula One career. Nigel Mansell, whose car broke at the start of the first race, got into his teammate Piquet's spare car and won the race; although this was the last F1 race at Brands Hatch. A number of people had concerns about the speeds of the cars on the small track; particularly the European Grand Prix held at Brands Hatch the previous year. The southern English circuit was getting to be very fast- now with these 1,000+ hp, 1,180 pound cars, pole sitter Piquet's average qualifying speed was 140.483 mph (227.583 km/h) and his lap time was in the 1 minute 6-second range, compared to the 1 minute 20-second range in 1976. But Brands Hatch's demise was for political reasons- the international motorsports governing body at the time, FISA, had instituted a policy of long-term contracts for one circuit per Grand Prix. Brands Hatch was perceived as a poorer facility, and considering most of the track was located in a very old forest it did have very little run-off and room to expand, something Silverstone had in acres. Silverstone and the BRDC had signed a seven-year contract with Formula 1 and FISA at some point in 1986, to run from 1987 to 1993.
The Le Mans Classic is a biennial vintage sports car event held on the grounds of the 24 Hours of Le Mans, create by Peter Auto and Richard Mille, and associated with Automobile Club de l'Ouest (ACO). It began in 2002 and runs every two years in July on the full 13.65 km circuit also used for the annual modern day 24 Hours of Le Mans. The Le Mans Classic event of 2002 was the first time since 1923 that the full 24-hour Circuit, part of which is public road the rest of the year, was closed specifically for an event other than the annual running of the "24 heures du Mans" with contemporary sportcars and prototypes, thus allowing car owners and gentleman drivers to experience what it must have been to race these cars on this circuit.
The Australian Grand Prix, which was one of the world's oldest Grands Prix having first run in 1928, was added to the Formula One World Championship for the first time in 1985. The race was held in Adelaide, South Australia on a street circuit on 3 November as the last race of the season. The Adelaide Street Circuit was praised by the Formula One fraternity, most of whom arrived down under fully expecting another bad street circuit like Las Vegas, Detroit and Dallas, but instead found a fast, open circuit with a 900-metre long straight where the faster cars reached over . The 50th running of the Australian Grand Prix won the Formula One Promotional Trophy for Race Promoter as the best race meeting of the year. FOCA boss and Brabham team owner Bernie Ecclestone shocked a press conference when he declared that he believed that the standard of the organisation and the circuit itself was bad news for Formula One. He then explained to the shocked media that Adelaide had raised the standards of what would be expected in the future and that several tracks in Europe already on the calendar, or hoping to be, would have to lift their own games in order to match it.
Built in the Magdalena Mixhuca public park in 1959, the circuit hosted its first Formula One Grand Prix in 1962, as a non-Championship race. The following year the Mexican Grand Prix became a full World Championship event. The circuit remained part of the F1 calendar through 1970, when spectator overcrowding caused unsafe conditions. When the track re-opened in 1986, the circuit boasted a new pit complex, as well as improved safety all around. In 2001 CIE and Forsythe Racing tasked D3 Motorsport Development with revamping the circuit. A redesign to include the Foro and a complete upgrade of the circuit was done. It saw a record crowd of 402,413 people attend a round of the CART Championship in 2002. As of 2018, the Autódromo Hermanos Rodríguez has been the only venue for the F1 Mexican Grand Prix.
The Circuit de Barcelona-Catalunya was built in 1991 and began hosting the Spanish Grand Prix that same year. Construction also coincided with the Olympic Games scheduled to take place in Barcelona the next year, where the circuit acted as the start and finish line for the road team time trial cycling event. The Circuit de Barcelona-Catalunya should not be confused with the Montjuïc circuit, which hosted the Spanish Grand Prix four times between 1969 and 1975 and, unlike the Circuit de Barcelona-Catalunya, is actually located within the city of Barcelona.
The 1964 British Grand Prix was a Formula One motor race held at Brands Hatch on 11 July 1964. The event was also designated as the European Grand Prix. It was race 5 of 10 in both the 1964 World Championship of Drivers and the 1964 International Cup for Formula One Manufacturers. The first of twelve British Grands Prix to be held at the southern England circuit, it would alternate with Silverstone until 1987. The race was won by Jim Clark driving a Lotus 25.
The 18th BRDC International Trophy was a motor race, run to Formula One rules, held on 14 May 1966 at the Silverstone Circuit, England. The race was run over 35 laps of the Silverstone Grand Prix circuit, and was won by Australian Jack Brabham in the Brabham-Repco BT19. With no Race of Champions in 1966, the International Trophy formed the first major race of the European season, being run just a week before the start of the FIA World Championship in Monaco. The 1966 season was significant, as changes to the F1 formula had allowed an increase in engine capacity from 1.5L to 3L. This then was the first opportunity for many teams to test their new cars against top-line opposition.
The Circuit de Spa-Francorchamps is a race track that is 7.004 kilometres (4.352 mi) long and has twenty corners. Endurance racing events were first held at the Circuit de Spa-Francorchamps in 1924 with the Spa 24 Hours. Thirty-nine years later, the track began holding World Sportscar Championship races which later expanded to . It was cancelled after the 1975 running because of modern safety concerns. It was resurrected in 1982 on the reconfigured Spa-Francorchamps track layout and remained on the calendar until 1990. Spa-Francorchamps again began holding endurance sports car races from 1999, and the 6 Hour event was made part of the FIA World Endurance Championship in 2012. The race is considered by many as a final preparation event for the 24 Hours of Le Mans.
In earlier years, the European Grand Prix was not a race in its own right, but an honorific title given to one of the national Grands Prix in Europe. The first race to be so named was the 1923 Italian Grand Prix, held at Monza, and the last was the 1977 British Grand Prix at Silverstone.
The 1968 South African Grand Prix was a Formula One motor race held at Kyalami Circuit on Monday 1 January 1968. It was race 1 of 12 in both the 1968 World Championship of Drivers and the 1968 International Cup for Formula One Manufacturers. The 80-lap race was won by two time World Drivers' Champion and 1965 Indianapolis 500 winner Jim Clark for Lotus-Ford after starting from pole position. The race is significant as not only the last Formula One race to be won by Clark, but also the last in which he ever competed, due to his fatal crash at the Hockenheimring in Germany three months later. At this race Team Gunston became the first Formula One team to paint their cars in the livery of their sponsors when they entered a private Brabham for John Love.
Work on the Circuit de Barcelona-Catalunya was underway in Barcelona thanks to the support of the Spanish government, and in 1991, the event moved to this new track, where it has remained since. The 1992 event was advertised as the Grand Prix of the Olympic Games. Since that race the race has been held in early season, usually in late April or early May.
The European Grand Prix was a filler race – Grands Prix in New York City and Rome did not materialize and were cancelled; this race came 3 weeks after the Belgian event. This race was held at the fast southern English Brands Hatch circuit, normally used for the British Grand Prix on even numbered years. This race was a very exciting one: Senna took his 6th pole position at an average speed of more than 140 mph (228 km/h). There had been some concerns about racing these very powerful cars at the small, very fast Brands Hatch circuit: Niki Lauda and a few other drivers felt the cars were too fast for a short circuit like Brands, and if the power of the engines increased over time, the circuit would have to be modified in order to accommodate the cars.
Senna led from pole position and was harried by Rosberg. Going into Surtees Rosberg tried to get past Senna, but Senna took his line forcefully and Rosberg spun to avoid contact. Piquet hit Rosberg and retired, but Rosberg was able to get to the pits and returned to the track right in front of Senna who was then being harried by Mansell. Rosberg then held Senna up whilst going into Surtees, which enabled Mansell to overtake into the lead.
Mansell led the rest of the race distance, while Marc Surer in a Brabham-BMW got up to 2nd, but retired at Stirling's corner after a fire broke out on the back of his car. Meanwhile, Alboreto's car failed and caught fire; he drove it back to the Ferrari pit while up in flames, in an effort to get the message across to his team about his car's most recent unreliability that cost him the championship. Prost, however, made a very bad start, dropped to 15th and finished in 4th, which was enough for him to become world Drivers' Champion for the first time. He finished behind Mansell, Senna, and Rosberg, who drove a storming race to finish 3rd.
A type of hybrid between the purism of open-wheelers and the familiarity of touring car racing, this style is often associated with the annual Le Mans 24 Hours endurance race. First run in 1923, Le Mans is one of the oldest motor races still in existence. Other classic but now defunct sports car races include the Italian classics, the Targa Florio (1906–1977) and Mille Miglia (1927–1957), and the Mexican Carrera Panamericana (1950-1954). Most top class sports car races emphasize endurance (typically between 2.5–24 hours), reliability, and strategy, over pure speed. Longer races usually involve complex pit strategy and regular driver changes. As a result, sports car racing is seen more as a team endeavor than an individual sport, with team managers such as John Wyer, Tom Walkinshaw, driver-turned-constructor Henri Pescarolo, Peter Sauber and Reinhold Joest becoming almost as famous as some of their drivers.
It was the 21st Spanish Grand Prix since the race was first held in 1913. It was the fourth, and last, Grand Prix to be held on the Montjuïc street circuit. The race was shortened to 29 of its scheduled 75 laps, a race distance of 109 kilometres. The race was won by German driver Jochen Mass driving a McLaren M23. It would be the only Formula One win of his career. Mass had just a second lead over the Lotus 72E of Belgian driver Jacky Ickx when the race was declared. Argentine racer Carlos Reutemann was declared third in his Brabham BT44B, a lap behind the race leaders after a penalty was given to Jean-Pierre Jarier. This was the final win by a German driver until Michael Schumacher won the 1992 Belgian Grand Prix.
One of the oldest existing purpose-built automobile racing circuits in the United States, still in use, is the 2.5-mile (4.02 km)-long Indianapolis Motor Speedway in Speedway, Indiana, built from March to August 1909, when it first opened for racing. It is the largest capacity sports venue of any variety worldwide, with a top capacity of some 257,000+ seated spectators. The oldest asphalt-paved oval track in the United States is Thompson Speedway Motorsports Park in Thompson, Connecticut, once known as the "Indianapolis of the East."
"Gran Turismo 6" was announced on May 15, 2013, when Sony Computer Entertainment Europe hosted a celebration of the 15th anniversary of Gran Turismo at Silverstone Circuit in the United Kingdom. Kazunori Yamauchi said at the official announcement, "Gran Turismo 6" will feature 71 layouts of 33 tracks, 1200 cars, a new flexible rendering engine that features adaptive tessellation, and a redesigned simpler menu interface with faster loading times. An early build of Gran Turismo 6's updated physics was shown to the public when GT Academy 2013 was released on the PlayStation Store on July 2, 2013.
On July 10, 2013, game developers announced that the Goodwood Festival of Speed hill climb course will be included on the game. The 1.16 mile strip of road that runs through the Earl of March's family home's grounds hosts the annual Festival of Speed and current Formula One, Moto GP, World Rally Championship cars and racers as well as other famous drivers and cars from all ages and aspects of motor sport. This gave the game developers the idea to base a track here due to the wide variety of vehicles that use the hill climb in front of 185,000 spectators. Yamauchi said "I have always been a huge admirer of the Festival of Speed and what Lord March has achieved, I love the incredible range of cars on display – from the priceless, rare and exotic, to the latest family hatchback and full on racing cars – I love the challenge of the Hill Climb and the rally stage. Goodwood represents every type of motoring and motor sport which very much mirrors what we aim to achieve with Gran Turismo and so it is very special that we have forged this partnership. There will be no better feedback than that provided by the Goodwood fans to tell me if we are heading in the right direction with "Gran Turismo 6"!" A demo of GT6 was made available at the Festival, to give spectators the chance to challenge Nick Heidfeld's 41.6-second course record set in 1999 in a Formula 1 car.
The Detroit street circuit's place in Formula One history was assured when Italian Michele Alboreto won the 1983 race driving a Tyrrell 011. It was the last ever of 155 grand prix wins for the 3.0L Cosworth DFV V8 engine which had made its debut back in 1967 when legendary Team Lotus boss Colin Chapman matched his Lotus 49 with the engine. The DFV had won on debut at the 1967 Dutch Grand Prix in the hands of dual World Champion Jim Clark. It was also the last of 23 Formula One race wins for Tyrrell, who had won their first grand prix as a constructor at the 1971 Spanish Grand Prix with that year's World Champion Jackie Stewart driving the Tyrrell 003.
The race was won by Mike Hawthorn driving a Ferrari; it was his first Formula One victory since the 1954 Spanish Grand Prix and would prove to be his last. It was also the last Formula One race for five-time World Champion Juan Manuel Fangio. On the final lap, Hawthorn eased up to let Fangio, running fifth at the time, finish on the lead lap of his last race. This turned out to be a blessing, as Peter Collins crashed on the final lap, allowing Fangio to secure fourth.
After this first race, the track fell into financial difficulties, and the organisers had to look for another venue. In 1926, the Spanish Grand Prix moved to the 11-mile Circuito Lasarte on the northern coast near Bilbao, home of the main race in Spain during the 1920s—the San Sebastián Grand Prix. The 1927 Spanish Grand Prix was part of the AIACR World Manufacturers' Championship, but the race was still not established and in 1928 and 1929 was run to sports car regulations. The 1930 Spanish Grand Prix for sports cars, scheduled for 27 July, was cancelled due to the bad economic situation following the Wall Street crash in October 1929. The 1931 and 1932 Spanish Grands Prix were also announced, only to be cancelled due to political and economic difficulties. Finally, in 1933 the Spanish Grand Prix was revived at Lasarte with government backing. Following the 1935 race, Spain descended into civil war and racing stopped. In 1946, racing returned to Spain in the form of the Penya Rhin Grand Prix at the Pedralbes street circuit in Barcelona.
The 80-lap race was won by Peter Revson, driving a McLaren M23, after starting from second on the grid. This turned out to be Revson's last victory and podium finish in Formula One. As of the conclusion of the 2018 Formula One World Championship, this is the last Grand Prix to be won by an American-born driver. Emerson Fittipaldi took second position for Team Lotus, while Jackie Oliver took third in a Shadow, his first podium in five years and his last of all.
On 20 June 2009 Bernie Ecclestone stated that there would be a British Grand Prix at Silverstone in 2010 if Donington was not ready to host it. When asked why he had moved from his previous "Donington or nothing" standpoint he cited changes in the structure of the BRDC meaning there was a better way of negotiating with them over future commercial rights. Furthermore during an interview with the BBC about the Formula One Teams Association threatening to break away and form their own series, FIA president Max Mosley said it was "highly likely" the 2010 British Grand Prix would return to Silverstone. On 24 October 2009, BBC News reported that Donington had failed to raise the £135 million needed to stage a British Grand Prix, that Donington's bid 'looks over' and that Bernie Ecclestone had offered the race to Silverstone, but that the terms appeared to be the same as those that the Circuit rejected the first time around.
On 1 March 2011, Silverstone Circuits confirmed that the Bridge section of the track had been decommissioned and would not be used again. Large scale earthworks are currently taking place to open up this area for spectators. ""The old Bridge section of the circuit has been decommissioned and this has been sanctioned by the BRDC – however please note that the tarmac will still remain intact and not be removed. This decision was not taken lightly but with the development of The Silverstone Wing and the new pit lane exit, the Bridge section of the Grand Prix Circuit has been made redundant. The banked area that you have shown in your photo will open up the track at Luffield and will become a new spectator area bringing fans closer to the action.""
1964 saw the first Formula One race at the southern English circuit known as Brands Hatch, located in Kent, just outside London. The track was built in the early 1950s and had been extended in 1960. Silverstone hosted the British Grand Prix in odd-numbered years and Brands Hatch in even-numbered years. Like Silverstone, the circuit was popular with drivers, and unlike the flat Northamptonshire circuit and Aintree, Brands Hatch had many cambered corners and lots of elevation change. Like the year before at Silverstone, Clark won the 1964 race, and the next year's race. 1967 saw Clark take yet another dominant win, and 1968 saw a monumental battle between Swiss Jo Siffert in a Lotus and New Zealander Chris Amon in a Ferrari; Siffert won the race, his first of two victories in F1 on the circuit where he would lose his life in a non-championship race 3 years later.
On 7 December 2009, Silverstone was awarded the rights to host the British Grand Prix for the next 17 years. Part of the deal was for a new pit lane to be built.
