Renault had planned to have Robert Kubica as teammate to Petrov, but Kubica got injured while testing a rally car. 'It is very busy right now, but the intensity of the new car will build steadily to insane levels as January approaches,' he added.The R31 was unveiled at the Circuit Ricardo Tormo in Valencia, Spain on 31 January 2011, where Vitaly Petrov was first to drive it. Next season brings a ban on blown diffusers thanks to new rules which limit the positioning of a car's exhausts and Allison said that work on Renault's 2012 design is well advanced.

'We look forward to moving on in 2012 with all-new exhaust rules and a chance to wipe the slate clean.' Intensity 'The layout which had promised so much and which, had it delivered, would have been almost impossible to copy, proved very tricky to develop and had a fundamental weakness in slow corners that has been an albatross around our neck all year. 'The season which followed has been difficult for everyone at Enstone. 'We came out of the blocks adequately well, although it was clear from the first test that the delivered downforce was not as high as we had expected. 'We were the only team to adopt a forward exhaust layout, and we did so with high hopes, buoyed by very strong wind tunnel numbers. It worked to an extent, however the car's traction suffered as a result out of slower corners, with its performance notably poor at tracks like Monaco, Hungary, Singapore as well as Abu Dhabi's Yas Marina Circuit.Īsked for his verdict on Renault's R31, Allison said: 'I regard it as a bold, but ultimately failed experiment. Unlike the blown diffusers used by rivals, the intention was for the R31 to develop more grip towards the middle of the car.

Renault took a bold step with a unique forward-facing exhaust on their car. They picked up a total of 66 points in the first half of the season but have managed to score just six since then, with Vitaly Petrov forced to apologise after the recent Abu Dhabi Grand Prix where, having finished one lap down in 13th place, he criticised the team in a post-race interview.
