Formula Renault are classes of formula racing popular in Europe and elsewhere. Regarded as an entry-level series to motor racing, it was founded in 1971, and was a respected series where drivers can learn advanced racecraft before moving on to higher formulas.
Renault now backs the French F4 Championship and Formula Regional European Championship. The World Series by Renault once included Formula Renault 3.5 before becoming World Series Formula V8 3.5 in 2016, then folding in 2017.
Formula Renault 3.5L
The most senior "Formula Renault" was the Formula Renault V6 Eurocup started by Renault to run as part of Eurosport's Super Racing Weekends (ETCC and FIA GT Championship). Only two seasons were run between 2003 and 2004 before Renault left Super Racing Weekends and merged the series with the similar World Series by Nissan to create the Formula Renault 3.5 Series as part of the World Series by Renault in 2005. In 2016 the series became the World Series Formula V8 3.5, which folded in 2017.
Formula V6 Asia started in 2006 in Asia and ran at Asian Festival of Speed Weekends (Touring Car, Formula BMW and Porsche Carrera Cup Asia).
The old Eurocup and current Asian formulas use Tatuus chassis, while the World Series uses Dallara cars. Michelin is the tyre supplier.

A Pan Am Formula Renault V6 series was planned to take place in 2005 but it never occurred.
Formula Renault 2.0
Formula Renault 2.0 descended from Formula France created in 1968. Its predecessors used 1.3L (1968–1971), 1.6L (1972–1981), 1.6L turbo (1982–1988) and later 1,721 cc (1989–1994), then 2l 8V (1995–1999) engines in single-seater chassis. The series evolved in 2000 into a 2L 16V series using one-make cars from Italian manufacturer Tatuus. The series was introduced into the UK in 1989 and even after the 1721 cc cars had been replaced at the top level a club-level series for them continued in parallel with the more ambitious 2.0 series. This is seen as one of the key steps in a driver's career before Formula Three.
The most notable recent graduate of the formula is Kimi Räikkönen, who moved straight into Formula One after winning the British Formula Renault championship.
The cars
1995–1999
The Formula Renault 95 used multiple chassis, production 2.0-litre 8V 165 hp engines and Hewland five-speed manual gearboxes. Manufacturers were able to build cars around spec components such as the engine, bellhousing, gearbox, brakes, wheels and ECU. Chassis were steel space frame with fibreglass bodies. Manufacturers included Mygale, Martini, Swift, Tatuus, and Ermolli. The car was last used in 1999.
2000–2009
The Formula Renault 2000 had a Tatuus-made chassis running 2.0 L Renault Clio engines attached to a Sadev gearbox. The engine originally had a maximum output of 185 hp, and was upgraded to 210 hp in 2006. They are capable of accelerating from 0 to 100 km/h (0-62 mph) in 4.85 seconds and braking from 200km/h (124 mph) to a stop in 4.60 seconds. The Tatuus Formula Renault car is the most successful single seater ever, with 10 years of service and nearly 1000 sold. The car has produced many current Formula One stars, with 11 of the 25 drivers in the 2009 Formula One season using the car in the infancy of their careers.
For the 2010 season, a new car developed by Barazi-Epsilon, will be used in most major championships, with the old car still being used in minor championships such as Formula Renault BARC in the UK.
