The Renault RS10 was a Formula 1 car developed to compete in the 1979 Formula One season , which became the first turbocharged F1 car to win a Grand Prix . This changed the framework of F1 as this car spurred the development of the 1,300 bhp (970 kW) turbocharged cars of the 1980s and rang the death knell for normally aspirated engines. This car, along with its predecessor, the Renault RS01 , was one of the most revolutionary Grand Prix cars of all time.
24-406: The RS10 was designed and developed by François Castaing, Michel Têtu and Marcel Hubert and was developed from the much-maligned RS01. The RS01 was conceived alongside Renault's effort to build a turbocharged Le Mans winning car. The RS01 was no more than a development mule for the 1.5-litre turbocharged engine. Jean-Pierre Jabouille with his engineering degree, mechanical aptitude and driving skill
48-722: A 3.7 liter V6 producing approximately 330 hp, and a 6-speed manual transmission. It will be homologated to FIA E II-SH regulation. More details are to be released in September 2018, and it is expected to go on sale in November 2018 at a price of €89,000. The Ligier model line currently consists of the JS50 line of mini cars, the X-Pro line of small commercial vehicles, and the Be Up/Be Two line of open-air, roadster-type vehicles. The company also produces
72-467: A line of quad bikes and off-road utility vehicles sold as the Be Pro, Be Four, and Be Truck. The JS50, Ixo, Xtoo, Nova or Ambra are about two and a half meters long and have two seats. They are front-engined. Power units include two 2-cylinder four-stroke diesels of about half a liter displacement and feature a CVT for power transfer. The Ligier vehicle that's gained the most attention, is EZ10 EasyMile ,
96-518: A mid-engined sports car for the road initially powered by a Ford V6 and from 1971 by the same Maserati V6 engine as the Citroën SM . The JS2 was considered by many as a well-designed car with a very good power-to-weight ratio . The Ligier motorcars were all designated with the prefix "JS" in honour of Ligier's great friend and cohort Jo Schlesser who was killed in the 1968 French Grand Prix while driving for Honda . The final SMs were also produced in
120-607: A self-driving shuttle bus for light city transit. EasyMile SAS develops and markets the autonomous vehicles, and is a joint venture formed in June 2014 by Ligier and Robosoft Technology PTE Ltd (France). The joint venture is the result of the CityMobil2 project co-funded by the European Union's Seventh Framework Programme for research and technological development (FP7). One EZ10 minibus can take between 8–10 passengers, and its speed
144-503: A serious contender with a Renault Gordini twin-turbo 1.5-litre V6. Where the RS10 differed from the RS01, however, was that it incorporated twin-turbochargers, a 6-speed transmission and a completely new ground effect chassis. The RS10 was introduced a third of the way through the 1979 season at the 1979 Spanish Grand Prix . Initially only one car was available for Jean-Pierre Jabouille and it retained
168-415: A turbo program in the 1980s, soon to be joined by the likes of McLaren ( TAG - Porsche ) and Williams ( Honda ). The other major manufactures did so as well as the turbo cars began to gain power and reliability. Soon all the major teams had forced-induction power. The smaller, mainly British teams (most notably Tyrrell who were the last major team to turn to turbo power, Renault no less, in 1985 ) lacked
192-514: Is a French engineer best known as a designer of racing sports cars and Formula 1 (F1) cars for marques such as Ligier , Alfa Romeo , and Renault . Têtu was born in Châteauroux , France, in the department of Indre . He graduated from l'École des Techniques Aéronautiques et de Conception Automobile (ETACA), which became l' École supérieure des techniques aéronautiques et de construction automobile (ESTACA) in 1978. He also took classes with
216-697: Is up to 40 km/h (25 mph). In 2017, EZ-10 was introduced on the grounds of National Taiwan University in Taipei, and in Tallinn , Estonia . In conjunction with Estonia's presidency of the EU Council, the minibus was presented in Tallinn on 14 July 2017 by EasyMile, and the tech companies in Estonia that co-financed the month-and-a-half-long project to bring the shuttle bus to the country. The buses will serve one line, including
240-644: The 1975 World Championship for makes . In 1976, Têtu was contacted by Gérard Larrousse , then with Renault, about the possibility of him joining the company for a special project. Têtu returned to France and began working for Renault Sport in Dieppe. He became one of the lead engineers on Renault's Projet 822, which was released as the Renault 5 Turbo . He was asked to drive the prototype on its first outing. Têtu's other projects at this time included preparing Alpine A310s for Group 4 competition. He also developed
264-633: The Ligier JS3 sports racing barquette, and then the Ligier JS2 sports coupé. He then joined Alfa Romeo's Autodelta competition division. He had been brought in to consult on the aerodynamics of the T33/2 Daytona coupé. When he arrived in 1972, Têtu was put in charge of the eight-cylinder Tipo 33s, which were near the end of their development life. He also drew the shape of the Alfa Tipo 33 TT 12 that won

While there he was involved with the Le Mans cars, initially the Panhard-engined LM64 , and later the Peugeot-powered SP66. Têtu moved to Ligier in 1969. His first three major designs included Ligier's debut model, the Ligier JS1 sports coupé, followed by
336-722: The Ligier factory in Vichy . The 1973 energy crisis caused such a decline in the market for the JS2 that production ceased soon after, and the firm changed its focus to microcars , beginning with the 1980 moped -powered Ligier JS4 . One of the world's first experimental prototypes of automatic parallel parking was developed on a Ligier electric car at INRIA in the mid-1990s. In September 2008, Ligier Automobiles completed its acquisition of Beneteau Group's Microcar division, with financing provided by 21 Investimenti Partners . Phillipe Ligier, son of

After the announcement of the creation of the new category LMP3 by the ACO, Ligier and Martini associated with Onroak Automotive (the manufacturer department of OAK Racing ) to offer a full range of prototypes ( CN , LMP3 , LMP1 and LMP2 ). The firm entered the automobile business with the Ligier JS2 ,
384-567: The Renault 5 Alpine Group 2 rally car, which finished second and third at the 1978 Monte Carlo Rally . At the 1978 24 Hours of Le Mans , Têtu was the race engineer for the winning team of Jean-Pierre Jaussaud and Didier Pironi and their Renault Alpine A442 . In 1978 Têtu moved to the Renault Formula 1 team full time. He designed Renault's first ground effect F1 car, the RE10 (also called

The merger creates Europe's second largest microcar manufacturer (after Daimler's Smart unit , if one considers that a microcar), and largest manufacturer of drivers license-exempt vehicles. In August 2018, Ligier teased a new road-going sports car to celebrate their 50th anniversary. The car will be built in collaboration with Onroak. It will feature
432-469: The engine troubles. Jabouille in particular saw his hard work hardly rewarded thanks to the new engine technology. His win in Dijon though, in front of home fans with an all French car, engine, tyres and even French fuel (Elf), was his prize for three hard years of no results. The car and team that began as a joke quickly had the paddock scrambling. Ferrari and Brabham (using BMW engines) quickly put together

In an attempt to limit soaring engine power outputs (by 1986 , the 4cyl BMW engine was reportedly producing around 1,400 hp (1,044 kW) in qualifying, with the Renault's output quoted at around 1,300 hp (969 kW)), and
504-535: The single turbocharger of its predecessor. At the Monaco Grand Prix a second car became available for René Arnoux and twin turbochargers were used for the first time. Though reliability issues still plagued the new twin-turbo, its pace made the paddock finally take notice. Through the final eight races of the season the RS10 scored five poles and one memorable home win at the 1979 French Grand Prix at Dijon-Prenois . More wins would surely have followed if not for

The Renault turbo effort was a joke along the paddock as the RS01 earned the moniker "Yellow Teapot" as its race would often end with the yellow car smoking and parked. It would not be long however, before the jokes and laughs along the grid turned to panic. The RS10 was finally built in 1979 as
