Renault unveil 2014 V6 Formula 1 engine

With the British Grand Prix around the corner, Renault have unveiled their 2014 turbocharged Formula 1 engine.

The new engine has been named as Energy F1. It is also Renault's first design for the sport's new turbocharged, energy-recovery technology era.

Four-time world champion turned Renault ambassador Alain Prost said, "From 2014 we will bring engines to the fore and redress the balance in F1. An engine is the heart of a car, from next year it returns to the heart of our sport."

According to the deal, Renault will continue supplying their title-winning works partner Red Bull next year, as well as the RBR's sister team Toro Rosso, which have so far used Ferrari power.

However, the French firm will continue to power Caterham.
