The Renault RS27 engine has been used in Formula 1 since the 2007 season. The V8, normally aspirated, 90° configuration unit is now capable of delivering up to 750bhp throughout its life.
The unit was recognised as one of the most reliable in the grid in 2011, able to complete over 3,000km with little power drop off.

Engine regulations for 2012
The V8, normally aspirated, 90° configuration with 18,000rpm output and 95kg weight limit has been applicable from the start of the 2007 season, but changes are permitted to improve chassis installation, to solve reliability issues or for ‘fair and equitable reasons’.
KERS is permitted but not obligatory. One fully charged unit can deliver up to 400kJ to give a max power equivalent to 60kW. This gives a powerboost of approximately 80bhp for between six and seven seconds per lap.
Eight engines are permitted per driver per season, even with 20 races on the calendar, one more than 2011.
Engine torque may only be generated through the steady application of the accelerator by the driver, and not through engine mapping or pre-programmed specific points along the accelerator pedal travel range.
This ‘accelerator pedal shaping map’ can only be used to fine tune the balance to the type of tyres fitted to the car, ie. the only changes permitted will be related to ‘dry’ or ‘wet’ settings.
So the engine is run in the most efficient way possible, any additional exhaust blowing will be prohibited this year.
Engine control must not be influenced by clutch position, movement or operation.
The idle speed control target may not exceed 5,000rpm.
Ignition, fuelling and throttle may not be used to artificially control the engine speed or alter the engine response in a rev range more than 1,000rpm below the final rev limit.
Engine exhaust systems may incorporate no more than two exits, both of which must be rearward facing tailpipes, through which all exhaust gases must pass.
The engine must be run in either an 8 or 4 cylinder mode. Any other patterns are no longer permitted.
About our partners
Red Bull Racing
Drivers: Sebastian Vettel & Mark Webber
The Red Bull Racing-Renault partnership started in 2007 and has since grown into one of the most successful engine-chassis partnerships in the history of the championship, with 27 wins and 38 pole positions so far and the double constructors’ and drivers’ titles in 2010 and 2011. Red Bull Racing and Renault Sport F1 announced a five-year extension of its partnership at the 2011 Italian Grand Prix. The two will work together until at least the end of the 2016 season, with the establishment of a technical joint venture to collaborate on the new engine regulations due to be introduced from 2014.
Lotus F1 Team
Drivers: Kimi Raikkonen & Romain Grosjean
Renault has a long and successful connection with the Enstone team. The relationship started in 1995 when Renault supplied engines to the then Benetton team, led at the time by Michael Schumacher. In the first year of the partnership Schumacher took the drivers’ crown and the team the constructors’ title. After withdrawing from official engine supply at the end of 1997, Renault returned to the fore at Enstone in 2002, taking control from Benetton and creating the Renault F1 Team. Enstone was the UK base for the chassis operations while Viry-Châtillon remained the hub for engine activities. Under the Renault banner, the team re-emerged as a dominant force, with Fernando Alonso taking back to back world titles in 2005 and 2006. A decision to re-centre F1 activities around engine supply led to a minority shareholding being sold to Genii Capital in 2009 before the Luxembourg-based group purchased 100% control at the end of 2010.
Williams F1 Team
Drivers: Pastor Maldonado & Bruno Senna
2012 sees the return of the historic Williams-Renault partnership to the grid. The duo originally teamed up in 1989, with success rapidly following. Nigel Mansell secured the partnership’s first double title in dominant form in 1992, with Prost retaining the crowns in 1993. Damon Hill and Jacques Villeneuve secured drivers’ titles in 1996 and 1997 respectively, while the constructors’ championships were secured in 1994 and 1996 – 1997 before Renault’s withdrawal from F1. Over the nine years of the partnership, the duo secured 63 wins, four drivers’ titles and five constructors’ wins. The partnership was revived for 2012.
Caterham F1 Team
Drivers: Heikki Kovalainen & Jarno Trulli
The Anglo-Malaysian squad entered 2011, its second season of competition in F1, powered by the Renault RS27 engine. Over the course of the year the partnership went from strength to strength and saw the team mix with the midfield in the second part of the season. Now equipped with the jointly developed Red Bull-Renault KERS package, the partnership should start to pay dividends this season.
