Sebastian Vettel drove 35 flawless laps in the second practice session Friday to edge Red Bull teammate Mark Webber for the quickest time ahead of Sunday’s Indian Grand Prix.
Vettel recorded 1 minute, 25.722 seconds on soft tires for his best lap on the Buddh International Circuit, .289 faster than Webber and almost a second quicker than his time of 1:26.683 in the first session.
Vettel, who has won both previous Indian GP races from pole, can win his fourth straight world title by placing fifth or better on Sunday.
Ferrari driver Fernando Alonso overcame gearbox problems in the morning session to finish the day fifth fastest, ahead of Nico Rosberg’s Mercedes and teammate Felipe Massa.
The second session was marred by handling problems as most drivers came to terms with the smooth, warming track and the softer compound Pirelli tires.
Kimi Raikkonen, who finished 17th in the morning session, appeared to be fighting a losing battle for control of his Lotus and had difficulties taking the tighter turns. He improved to eighth fastest, but looked far from comfortable ahead of Friday’s qualifying.
Pastor Maldonado had wheel problems again. The Williams driver who lost a wheel in practice for this month’s Japanese GP was forced to park at the entrance to pit lane Friday when he lost a wheel nut and eventually punctured his front right tire after 23 laps of the second session.
Weather at the track was hot and dry, with similar conditions forecast for Sunday.
Tire supplier Pirelli has dropped the more durable hard compound tires for the Indian surface, instead opting for soft and medium options. While the soft tires proved to be considerably faster, drivers complained of a lack of durability.
Alonso had a frustrating start to the first practice, completing only six laps before being forced into the pits with a gearbox issue and ending the morning with the 12th-fastest time. Ferrari repaired the problem in time for the second session, without the need to replace the gearbox.
