Soon in it will be a case of; the 2.4 litre V8 is dead, long live the 1.6 litre V6 turbo.

The pinnacle of motorsport will enter a new era next year, when, after three years of planning and development, the most significant technical change to hit the sport in more than two decades will be 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.

Fuel quantity for the race will be limited to 100 kg initially (-35% from now - currently unlimited).

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 of fuel permitted for the race, the new units will use 35% less fuel than their predecessors.

Renault is one of F1 engine maker that is pleased about the change and has released details about the new power unit it has created to meet the coming challenge.

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

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.

Five Power Units will be allowed per driver per season in 2014, reducing to 4 in subsequent years

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.

The new engine has a strong focus on improved vehicle fuel efficiency / reduced fuel consumption

Jean-Michel Jalinier, President of Renault Sport F1 said:“From next year, one of greatest challenges in F1 will be to maximise 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.”

Since entering their first Grand Prix, Renault-powered cars have won 11 Constructors’ world championships. Only Ferrari has a better record, with sixteen titles.
