Renault F1 turbo engine designated the Energy F1-2014

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.”

    Sound like a lazy wasp in a hairdryer. So weak and flat. No roaring and screaming, just hmmm hmmm hmm.

    And no, it won’t sound that different when it’s on the car with bodywork and exhaust. Just listen to the engine sound of the current v8 on Youtube clips in the same environment and on the car, very similar.

  • DRK

    looks funny lol..

    I just can’t get it out of my head that, compared to the current V8, the new engine:
    * costs more than twice as much
    * produces less power in the internal combustion engine (600 vs 730) and less power overall (750 vs 810) with (K)ERS
    * requires more cooling
    * is much heavier overall

    Not to mention the noise. Hope this doesn’t kill F1.

    Nevertheless, looks like another Renault little gem, I want one for my Beemer K75S!

    You neubees stop whining about the turbos, which in reality will add another dimension to the drivers skills or lack there of, who will need to be more precise on power on exit. That unless these floks use my electric turbo concept which winds the turbo until full exhaust pressure is reached then runs on exhaust alone. Some AH gringo stole it in college and went on to design flucking ugly volvos. It does not matter because later I slept with his ugly wife and made her a baby.
    whom he is not aware is mine.

    It’s a tamer sound, and will not be as shrill or high pitched. Nothing can be done for it. 8 cylinders revving to 18,000RPM produces a 72 KHz frequency, while 6 cylinders revving to 17,000RPM produces only 51 KHz. On top of that, turbo’s tend to muffle exhaust tone, creating a deader, less lively sound. For some, this won’t matter a whit. To others, who though the screaming 20,000RPM V10s or the Ferrari V12’s were the ultimate F1 sound, the V6 will be a serious turn off. I’m not a fan of it, but can live with it. Unfortunately, its just one more brick in the wall, between V6, DRS and KERS, plus stricter innovation restrictions and junk tires, it’s only a matter of time before F1 is nothing more than a humorous caricature of itself – all show and less go…

  • Spartacus

    All of this nonsense could easily have been avoided.

    Firstly, regulate the type of engine. V8, 2.4l max.

    Next, measure the amount of fuel the average team uses for each race.

    Finally, limit the amount of fuel each team can use per car to 10% less. Or even lower amounts.

    Result, more efficient engines. No artificial nonsense.

    That Renault unit only revs to 11K for now. I read it somewhere a couple of weeks ago.

  • =El Presidente=

    @kevinW @butterfly :

    Yeah i read that also somewhere.
    I agree that F1 is getting more and more show, and less go, it is a bloody shame..

    And as said, turbo’s make a different noise
    On that part i appreciate the indy-series, because they don’t pretend. everyone knows and excepts that a big part is show, and that concessions are made for that.

    sounds bad,, really bad, its not formula 1 anymore

    Let’s just hope the development program will add 50+ horsepower to these engines over the next give years. Plus, I think the FIA said they could add a second turbo in the future if the need arises.

    I bet the 2014 cars will be under-powered, even if the Ferrari will probably have the most powerful engine.

  • Butterfly 2.0

    “I bet the 2014 cars will be under-powered, even if the Ferrari will probably have the most powerful engine.”

    Are you suggesting that Ferrari will cheat to get the most powerful engine? I can’t see how, although I wouldn’t put it past them.

    Typically Ferrari design good engines, but need more fuel per race for any given performance. Their engineers are top quality; hence why they’ve often got the fastest car on the grid. They just need better race management and desperately a better lead driver.

    Engine development is allowed until 2018.

  • megatron

    Are you paid by Ecclestone or CVC to make such silly and nonsense comments?? This new Renault Energy F1 engine is a masterpiece of engineering, it´s intricate and sophisticated like never before in F1 history. Even an idiot should know about that. To get along with it and the rules you will have to be a very intelligent and tactical skilled driver. This is no “show”, it´s class-A technology. Bloody show is the technical irrelevant V8 dentist drills (who wreck ones nervous system) as background noise for CVC´s 1001 palace racetracks-business.

  • gary c

    the turbo feeds on high revs. can the power stay throghout .or do they scream the nuts of it throgh the gears

  • Jooles

    Unfortunately successive restrictions, such as reduced displacement and limiting rpm’s, are making f1 less and less interesting. If you watch a re run of a race 10 years ago you see drivers really struggling to keep their cars on the road. How often now do you see someone spin off other than because of mechanical failure? Hardly ever. I for one will be attending the BOSS series instead this year
