LONDON Nov 19 Renault's radical approach
to the design of this year's Formula One car has been a failure,
according to technical director James Allison.
"I regard it as a bold, but ultimately failed experiment,"
he said when asked about the R31 car in a team preview for next
week's season-ending Brazilian Grand Prix.
"We were the only team to adopt a forward exhaust layout,
and we did so with high hopes, buoyed by very strong wind tunnel
"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. The season which followed has been
difficult for everyone at Enstone.
"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."
Renault started the campaign after impressive pre-season
testing with Vitaly Petrov taking a third place in Australia and
Nick Heidfeld doing likewise in the second race in Malaysia.
The season then tailed off, with German veteran Heidfeld
departing in August.
Petrov has not scored in his last three races while
Brazilian Bruno Senna, Heidfeld's replacement since Belgium, has
managed just two points from seven starts.
Renault are fifth overall with 72 points and well behind
fourth placed Mercedes on 159.
The aerodynamic rules are changing for next year and Allison
hoped for an improvement.
"We look forward to moving on in 2012 with all-new exhaust
rules and a chance to wipe the slate clean," he said.
