- Jerez Test, Day Four
I'd be worried at Red Bull - Massa
Felipe Massa says he would be worried if he was in Red Bull's position by the end of the first week of testing in Jerez.
Red Bull completed just 21 laps over the course of the four days, while Williams managed 173 - of which 86 were completed by Massa on the final day. He said he would not be feeling as happy if he had been in the position of the world champions on Friday.
"I'd be worried," said Massa. "But at least they have some problems this year and are not two seconds a lap quicker like they were at some place this year! They are having some trouble and some issues and if you don't see the Red Bull winning all the time it can be positive for everybody."
Massa set the fastest time in damp and cold conditions on Friday that made the car particularly hard to handle, but said he was pleased with Williams progress.
"Being first is always nice," he said. "It's a long time since I finished a test first, but this is still the first test and there are many cars missing so it is still not enough. It's always good and it's always positive, making some more laps than we were doing before and still other teams doing more laps than us.
"There's also teams that were a little bit more prepared than us. Mercedes is one company [engine and chassis] so they had everything ready and they knew it worked before us, Ferrari as well. We just changed the engine and so many people inside, so making the car working straight away is not easy."
However, he said he still needed to get used to the new electronic brake-by-wire system, which is on the rear of all cars this year, as well as the extra torque from the turbo engines this season.
"The brakes work in a different way. They are electronic brakes, this famous brake-by-wire. I still need to improve a lot the way I'm braking because it's different and a little bit strange this time. I still need to understand the engine, you have a lot of wheelspin and a lot less downforce than last year. The engine is strong, but with less downforce it makes it difficult to drive and it's important to understand how we need to use the gearshift and the engine. For sure there is a lot to improve."
