Practice Two - Button on top in Turkey 28 May 2010
Jenson Button turned the tables on McLaren team mate Lewis Hamilton on Friday afternoon when, despite a bobble in Turn Eight on his best lap, he set the fastest time with 1m 28.280s. This time, however, the Red Bulls of Mark Webber and Sebastian Vettel separated the silver cars.
The Australian lapped in 1m 28.378s, the German 1m 28.590s. Both had problems, however. Vettel reported loss of water pressure at one stage, and Webber stopped with five minutes to go with smoke emanating from the rear of his RB6. He later confirmed his high-mileage engine had failed.
Behind them, Hamilton was fourth on 1m 28.672s from Ferraris Fernando Alonso on 1m 28.725s, and the Mercedes duo of Nico Rosberg and Michael Schumacher on 1m 28.914s and 1m 28.974s respectively.
Robert Kubica took eighth for Renault with 1m 29.225s, with team mate Vitaly Petrov again impressing with 1m 29.501s for ninth. An unhappy Felipe Massa completed the top 10 for Ferrari. The Brazilian twice went off road in Turn Eight; on the second occasion he got sideways and seriously flat-spotted his only set of soft tyres, so was unable to improve upon 1m 29.620s.
After his gaffe this morning Adrian Sutil responded with a strong lap of 1m 29.629s in the lead Force ndia, while Nico Hulkenberg improved to 1m 29.987s once a hydraulic issue had been solved on his Williams.
Kamui Kobayashi and Pedro de la Rosa were evenly matched in their BMW Saubers, taking 13th and 14th with 1m 30.053s and 1m 30.176s respectively, ahead of Sebastien Buemi in the second Toro Rosso on 1m 30.386s, Vitantonio Liuzzi in the second Force ndia on 1m 30.627s, Rubens Barrichello in the second Williams on 1m 30.766s and Jaime Alguersuari in the second Toro Rosso on 1m 30.933s.
Heikki Kovalainen was again comfortably the best of the new team runners with 1m 31.610s in his Lotus, but Virgin had a better handle on things with Lucas di Grassi on 1m 33.013s ahead of the second Lotus of Jarno Trulli, who had problems with third gear on his way to 1m 33.081s. Timo Glock was 22nd in his Virgin on 1m 33.312s, then came the HRTs of Bruno Senna and Karun Chandhok on 1m 33.420s and 1m 33.740 respectively.
Besides Massa, Kobayashi was a spinner, early on in Turn Eight, where Liuzzi also ran wide. Senna went off three times in Turn One and once in Turn Five, Schumacher got Turn One wrong, and Chandhok was off the road in Turns Three and 12.
