"It would be unjust to say that I'm 100 per cent confident we have done enough," White conceded. "We've got what is obviously a short-term plan for this weekend and in parallel we've got a longer-term look to see if we can do a more robust job for the future."
White added his thanks to Renault
Sport's partners, including parts suppliers and the F1 teams.
"We've had great support from Red Bull
and Lotus who suffered the failures and from Williams
and Caterham who didn't but have identical pieces on the car," he said. "Also from all the suppliers in the supply chain."
Lotus F1 team technical director James Allison seemed happy with Renault's response to the problem that emerged at Valencia.
"We just work with Renault
Sport ... We all just muck in together and try to get it fixed," he said. "I think it's probably just that the alternator was very near to the limit of what it could do. There's always a scattering components and one fell just the wrong side of the line."
And Adrian Newey said that while he was happy to work with Renault
to address the problem, there was little in practice for him or the Red Bull
team so do at this point. "It's a component failure that we'll work together to get on top of," he said.
