Renault unveil their F1 turbo engine for 2014 and beyond

Renault F1 Sport have distributed photos and details of their 2014 Formula 1 engine. The 1.6-litre V6 turbocharged unit has been named Energy F1-2014,highlighting the added importance of energy recovery systems (ERS) in next year’s Formula 1 regulations governing power units.

In 2014 the current 2.4-litre V8 engines, which rev to a maximum of 18,000rpm, will be replaced by 1.6-litre V6 turbocharged power units revving to a maximum of 15,000rpm.

The new engines will produce around 600bhp, but that will be complemented by a powerful ERS producing around an additional 160bhp and dramatically increasing powertrain efficiency by harvesting energy dissipated as heat in the exhaust or brakes.

Whilst the maximum power of the new units will exceed the output of current V8 engines, fuel efficiency will be radically improved with Renault predicting that the new powerplants will use 35 percent less fuel than their predecessors – important as fuel will be limited to 100kg per race next season.

As expected, the sound of the new unit will also be different to its predecessor as Rob White, Renault’s deputy managing director (technical), explained: “The engines remain high-revving, ultra-high output competition engines. Fundamentally the engine noise will still be loud.

“It will wake you from sleep, and circuit neighbours will still complain. The engine noise is just a turbocharged noise rather than a normally-aspirated noise: you can just hear the turbo when the driver lifts off the throttle and the engine speed drops.

“I am sure some people will be nostalgic for the sound of engines from previous eras, including the preceding V8, but the sound of the new generation power units is just different. It’s like asking whether you like Motorhead or AC/DC. Ultimately it is a matter of personal taste. Both in concert are still pretty loud.”

Renault will continue their world championship-winning relationship with Red Bull next season and the French firm will also replace Ferrari as engine suppliers to Toro Rosso. The two other teams Renault currently supply, Lotus and Caterham, have yet to officially confirm their 2014 engine plans.

Renault Press Release

In 2014 Formula 1 will enter a new era. After three years of planning and development, the most significant technical change to hit the sport in more than two decades is introduced. Engine regulations form the major part of the coming revolution, with the introduction of a new generation of Power Units that combine a 1.6 litre V6 turbocharged engine with energy recovery systems that will dramatically increase efficiency by harvesting energy dissipated as heat in the exhaust or brakes.

The maximum power of the new Power Unit will exceed the output of current V8 F1 engines however fuel efficiency will be radically improved. With only 100kg permitted for the race, the new units will use 35% less fuel than their predecessors.

Alain Prost, Renault ambassador and four-times Formula 1 World Champion, “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.”

For several years, Renault has used its racing know-how to develop fuel efficient engines for road cars, notably its Energy range. The objectives are clear: maintain or improve driving pleasure, vitality and acceleration with downsized engines to achieve lower fuel consumption and CO2 emissions.

Renault has employed these principles in developing the F1 Power Unit, creating a complete, and genuine, circular development process between road and track.

For these reasons, Renault has named the F1 Power Unit series ‘Energy F1’; clearly illustrating that the F1 Power Unit shares the same DNA as its road-going cousins.

Jean-Michel Jalinier, President of Renault Sport F1: “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. 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.”
