Renault has unveiled the new turbo-charged engine that it will provide to teams for the 2014 F1 season.

The French manufacturer revealed the new unit at the Paris Air Show at Le Bourget, with the engine being named as the Energy F1 in reference to the sport's move towards more environmentally friendly engines featuring energy recovery systems.

The maximum power of the new engine will exceed the output of current V8 F1 engines but with improved fuel efficiency, with teams set to use 35 per cent less fuel than with the engines currently being used.

Red Bull and Caterham will both retain their engine deals with Renault for the new season, while Toro Rosso has also inked a deal that will see it switch from Ferrari.

Lotus has yet to announce its plans for 2014 but is expected by many to stick with Renault for another year.

"From next year, one of greatest challenges in F1 will be to maximize energy efficiency and fuel economy while maintaining the power output and performance expected of F1 cars," Jean-Michel Jalinier, President of Renault Sport F1, said. "Renault has pioneered this technology in its road car engine range with the Energy series.

"Naming the Power Unit Energy F1 creates an unbroken range, from the Clio through to our competition department."
