Costa, meanwhile, addressed perhaps the biggest unknown facing the teams this season, as Bridgestone prepares to unveil a new range of tyres for the top flight following mandated changes in dimensions of the front wheels.
“As far as the tyres are concerned, it hasn't happened very often that we came to the first test with a new car with tyres we've never seen before, never used and never tested," the Scuderia's technical director noted, "This year, we're racing after only four tests. We're confident that Bridgestone has done some excellent work, but with changing the compound four tests might not be enough.
“Bridgestone is very interested in the tyre tests and they will analyse their behaviour after the long runs. More weight on the tyres has changed the single-seaters structure, and it's very unusual to start in that sense.”
Meanwhile, Luca Marmorini, who debuts as head of engines and electronics this season, explained how the team hopes to recover performance with engines that can't be modified.
“Nobody ever went beyond a certain level with the engines," he pointed out, "This year, we won't have any refuelling and the motor mechanics went to use the engines in ranges they hadn't thought of before. That's an interesting challenge in terms of performance research in the light of the 2010 rules. The motor mechanic's intervention can be found in the engine's use, because the rules don't allow modifications of internal parts, so it will be really interesting to see the results.”
