Renault R31 exhaust, Valencia, 2011

Renault’s radical front exit exhausts pictured

2011 F1 testingPosted on | Author Keith Collantine

The Renault R31 has been pictured sporting a radical exhaust arrangement.

The R31’s exhausts point out of the front of the sidepods, directing hot air underneath the car to improve the performance of the diffuser.

See Craig Scarborough’s article on his site for an explanation of how the exhaust works.

  1. Hey guys, i was just thinking…usually when engine catches fire, flames come out from exhaust, right?
    So, basically, now it will fire around the cockpit area in such case making it really unsafe for the driver?

    1. That’s a concern I share.

  2. Greta to see all the discussion regarding how this exhaust performs when the car is moving, but my question is regarding when the car is stationary for periods of time. When they are held for the longer times on the grid are exhaust fumes going in the driver’s face. Also the new location of this heat source. Is it going to make the Renault struggle more than the other cars. Will more heat be reaching the radiators?

  3. Pitstop is bit of a concern as well. Exhaust now routed almost directly to rear wheels crew. I’m beginning to think that this tech is far off from being straightforward benefit. And giving some conspiracy theories voiced here a thought too.

  4. Word is, McLaren has done the same thing with their exhausts!

      That would mean that it HAS TO give a serious performance boost.

        Oh, and I have read somewhere that Red Bull is said to be also built in a way that could suggest they will have FEE, but they’re not revealing it yet.
        Looking forward to see them all in Bahrain, hopefully LRGP will be up in front with BRB and Mclaren this year.

  5. the car it’s gonna bee the best now

  6. seems that radical word is common from 2009 brawn GP,
    but i can see their exhaust length and layout will backfire because of heat problem

    Soooo, has anyone actually got any video footage with it on track? I wonder how much different it sounds.

  8. there was some video in the comments elsewhere on this site. can’t remember where exactly, sorry.
    it doesn’t sounds really different, a bit rougher though
