saw some good results at a few races. In 1981, the Ferrari 126C Formula One car used a turbocharged V6 engine. Ferrari won the Formula One constructors' championship with turbocharged V6 engines in 1982 and 1983. Initial versions used a 120 degree V-angle, before switching to a 90 degree V-angle for the 1987 Ferrari F1/87 racing car. Other successful turbocharged V6 Formula One cars in the era of 1982-1988 were the McLaren MP4/2, McLaren MP4/3, McLaren MP4/4, Williams FW10, Williams FW11, Williams FW12, Lotus 95T, Lotus 97T, Lotus 98T, Lotus 99T and Lotus 100T. The Nissan GTP ZX-Turbo and Nissan NPT-90 competed in the IMSA sports car prototype category from 1985 to 1994 and used a turbocharged V6 engine loosely based on the Nissan VG30ET production car engine. The Nissan 300ZX used a similar engine to compete in the 1996-1997 All Japan Grand Touring Car Championship (now known as the 'Super GT' championship). Downsizing to V6 engines in open-wheeler racing became more common: the IndyCar Series switched to turbocharged V6 engines in 2012. the GP3 Series switched to naturally aspirated V6 engines in 2013. the Formula One World Championship switched to turbocharged V6 engines in 2014. the FIA Formula 2 Championship (formerly known as the GP2 Series) switched to turbocharged V6 engines in 2018. the FIA Formula 3 Championship (created from the merger of the GP3 Series and the FIA Formula 3 European Championship) began using naturally aspirated V6 engines from 2019. Use in marine vessels and railway engines V6 engines are popular powerplants in medium to large outboard motors. The first V6 engine to reach production was built from 1908 to 1913 by the Deutz Gasmotoren Fabrik in Germany. These V6 engines were used as the generator for gasoline-electric railway engines. Use in motorcycles The Laverda V6 was a racing motorcycle which was unveiled at the 1977 Milan show. It entered the 1978 Bol d'Or 24 hour endurance race, however it retired with mechanical issues after approximately 8 hours. Horex has produced road motorcycles with VR6 engines since 2012.
