“We have a lot of new parts. Hopefully it's going to work well, but you never know before you try them. We have no testing, so we have tried to be as prepared as possible but it's always a big question whether everything you put on the car is going to work. We're quite confident, but we will see what happens in practice,” said Buemi to reporters in Barcelona.
As BMW Sauber, the Faenza based outfit didn't bring any notable revisions to the STR4 during the first 4 races this season, targeting a major upgrade for their European debut in Catalonia. While aware of the fact that other teams have also improved (aerodynamically speaking, of course), Buemi can't think of other possibility than making another easy Q2 appearance.
“This aero package is the biggest thing since the beginning of the season. We don't know how much the others are going to improve, but I am confident. Without any mistakes, we should make it into Q2. In China, we made it really easily into Q2 and then into Q3. It's so close that two tenths either way can make the difference between it being easy and out,” added the Swiss rookie.
Toro Rosso will not benefit from a double diffuser in Barcelona, as their development of the rear part is strictly related to the work conducted by “big brothers” at Red Bull Racing. Since Christian Horner – team principal of the Milton Keyned based outfit – revealed they will not have a new diffuser ready by the Spanish Grand Prix, Toro Rosso can only wait.
