Energy F1-2014 will be as powerful as last year's engine yet more fuel efficient
Renault just released the images and full specification of their 2014 Formula One engine. The 1.6-liter V6 turbocharged unit has been named Energy F1-2014 to highlight the focus on efficiency and renewable energy by adding energy recovery systems (ERS) in next year’s Formula One regulations.
The new 1.6-liter V6 turbocharged power units rev to a maximum of 15,000rpm and will produce 760hp, similar to last year’s engine. Two motor generator units (MGU): MGU-H (H stands for Heat) is an exhaust energy recovery system while the MGU-K (K stands for Kinetic) harvests energy during breaking.
Renault is predicting that the new engines will use 35 percent less fuel than their predecessors - important as fuel will be limited to 100kg per race next season.
With engine sound being a vital part of each and every F1 race, engineers made sure that the engine’s performance would still be audible.
“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 neighbors 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," said Rob White, Renault’s deputy managing director (technical)
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.
