Renault has become the first manufacturer to unveil its all-new power unit for the 2014 Formula One World Championship.

The powerplant embraces the FIA’s new rules that come into effect next season, which will see the cars switch from a 2.4-litre naturally aspirated V8 to a turbocharged 1.6-litre V6 supported by an electric motor in the pursuit of improved efficiency and reduced fuel consumption.

The new direct-injection 1.6-litre Renault engine, which features a single turbocharger and a single exhaust outlet, has a rev limit of 15,000rpm (3000rpm lower than the outgoing V8) and will produce around 600hp (447kW).


While that’s down roughly 100kW on the output of today’s V8s, an additional 120kW is delivered by the electric motor, officially dubbed ‘MGU-K’ (motor generator unit kinetic).  It is connected to the crankshaft and accesses kinetic and thermal energy from an energy store and another MGU that is connected to the turbocharger.

Compared with the KERS of the current 2013 cars, the energy recovery system (ERS) of the 2014 power unit has twice the power and a performance effect 10 times greater.

The new rules will see cars limited to just 100kg of fuel per race, expected to reduce fuel consumption by an average of 35 per cent, while a new fuel-flow limit of 100kg/h will see a reduction of roughly 40 per cent.


The power units will also need to be more durable than their predecessors, with drivers permitted just five per year compared with eight in 2013.

Renault began designing its new power unit more than two years ago, first testing single engine cylinders before developing the ERS and this month running the complete power unit on a dyno for the first time.

The power unit will hit the track for testing in January ahead of its debut in the first round of the 2014 Formula One World Championship in March.

    The technology is great but the sound not so much. Will have to wait and hear a full field of them in Melbourne next year before passing final judgement.

    • Frostie

      I agree. In fact, that was my first concern with the new engine layout.
      I wish they’d chosen a straight-6 layout instead of a V6.

    I guess this is the year i finally stop watching F1. Turbo’s should never be allowed into the World’s Premiere Motorsport category, no matter how much extra power they generate or what effect they have on fuel efficiency.

    • Disqussor

      Why not Turbo Power? Alot of vehicle manufacturers are going that way to improve the performance whilst achieving economy benefits…Also the latest Hypercars are using electrical energy systems as well… Hasn’t F1 always been the testbed for future tech in road cars…? F1 will become More relevent now they’ve ditched the NA V8…

      • Shak

        I don’t think there is anything wrong with manufacturers going turbo as they make road cars which most of us use for the daily drive. F1 cars are meant to embody everything that makes ICE technology exciting and great, including sound. We all know that no matter how well a turbo engine is made it will always lose out on sound to a well designed NA engine NA simply sounds better, and for racing that’s the way things should stay.

    • Pav

      you do know that f1 have used turbo engines before? Many people argue it was the greatest era of f1 with the most brutally powerful cars and brave drivers.

        Except they were chasing absolute power; not efficiency.

      • Shak

        Refer to what Josh Kong said.

    emissions and fuel cons, its racing FFS!

  • F1orce

    Bad news.

    Why ruin a good thing? political correctness gone crazy..

    • Norm

      I know…we should have stuck to the horse and cart.

  • F1orce

    Might aswell have a big tag on the side of the new F1 written ‘HYBRID’

    • Pav

      F1 is already ‘hybrid’

  • Doctor

    Just 5 engines per team in the first year is a big ask, especially for Renault who have a reputation for “hand grenades”.

    • John

      Renault is in fact the most reliable engine supplier in F1. For them to win 3 constructors championships the last 3 years in a row is testimony to that. Not even Ferrari or Merc can challenge that.

  • Rocket

    The switch to a turbo V6 hybrid may not excite many but if the lap times don’t suffer and we still see plenty of overtaking I will still watch. Will they sound as good?? There is still NASCAR and V8 Supercars if a V8 is a must.

  • marc

    I’m sure F1 ran 1.5 litre V6 turbos in the mid 1980s. It was quicker than 3.4? V8s that immediately followed.

    • marc

      Just read in 1985 the 1.5t were producing 1100bhp in qualifiying trim and about 900bhp in race. No doubt there will be limitations in 2014. The v8s were 3.0L.

      • guest

        In the race, the Techniques d’Avant Garde TAG-P01 engines of McLaren were pushing out nearly 910hp – and in qualifying they could do just about 1060hp – down on the more peaky Honda, but the TAG-P01 was a better responding engine later on in its life as they sorted it out properly. The starting troubles at high altitude tracks early on its life certainly didn’t help, nor did the stuttering Motronic (until it was fixed).

        The ’86 turbo engines were the craziest.

        The turbos had a lot of power, but the response wasn’t the best.

        These modern Turbo engines won’t be the same beasts as we had in the old days. They won’t let them reach 900hp or more.
