Newey: RB 10 over-heating at Jerez was a result of aggressive packaging
17 February, 2014
Adrian Newey has admitted that one of the issues that afflicted the Red Bull RB10, during Jerez testing last month, was down to overheating caused by the aggressive aero packaging, not helped by the Renault V6 turbo’s propensity to run extremely hot, as we reported in the aftermath of Jerez testing [here].
Speaking to about 200 guests at the RAC’s Annual Motoring Dinner, Newey revealed, “What stopped us at Jerez was a problem where the bodywork local to the exhaust was catching fire.”
“Hands up on our side because that was a Red Bull problem. It was, you could argue, a result of aggressive packaging. We felt that we needed to take a few risks to try to get a good package that would minimise the aerodynamic damage of this very large cooling requirement.”
“It is a problem which hopefully we can get on top of [in time] for Bahrain. It was really a lack of time…it was something that we could have proved out on the dyno if we’d managed to get everything together earlier.”
“Renault have been up against it in terms of their use of the dyno, we have been up against it making the parts in time. I think had we been a couple of weeks further ahead then that could all have been done in private on the dyno, but unfortunately it was done in public.”
The overheating problem was not exclusive to Red Bull. The other two Renault powered teams present in Spain, Caterham and Toro Rosso, also experienced problems which also caused limited running, way off the pace.
Newey explained, “The Renault seems to have a particularly large cooling requirement. Everybody of the three engine manufacturers will have a different target for how hot their charge air is going back into the plenum and Renault have given us a fairly challenging target, with all sorts of advantages if we can get there, but it is not easy to achieve.”
Red Bull and the rest of the Formula 1 contenders begin the second chapter of 2014 pres-eason testing at Bahrain International Circuit starting on 19 February (GP247)
