There was no stopping Sebastian Vettel at the Buddh circuit on Friday afternoon as he set the pace on the medium and soft tyres ahead of Mark Webber...
The drivers were quickly into the action with Kimi Raikkonen leading the early running with a 1:28.419, comfortably ahead of Daniel Ricciardo and Nico Hulkenberg. The Finn lost out to his team-mate Romain Grosjean while Lewis Hamilton slotted into second ahead of the two Ferraris.
However, it was all-change when Sebastian Vettel, who last year claimed the P1 slot in all three practices, qualifying and the race came out for his first run of the afternoon and immediately went quickest. It was a 1:27.059 for the German.
Moments later the Red Bull racer was informed over his team radio that KERS issues. However, the team was confident they could fix it and Vettel headed into the pits.
With Vettel in the pits, Mark Webber went quickest with a 1:27.011 only to be pipped by Nico Rosberg by 0.001s!
The duo soon joined Vettel in the pits, swapping their medium tyres for the soft Pirellis.
Vettel was the first to improve, upping his pace to a 1:25.722, which was 1.233s up on his medium tyre best. Webber put up a challenge and was ahead of Vettel through the first sector but lost time in the final two. His soft tyre run was 0.289s off Vettel's.
Rosberg slotted into third behind the Bulls but was eight-tenths down while Kimi Raikkonen put his Lotus up to fourth ahead of Sergio Perez.
However, that all changed when Romain Grosjean, who had a brilliant race in Japan, came out for his soft tyre run and climbed to third place, 0.498s down. Lewis Hamilton was one of the last to swap and went fourth ahead of Fernando Alonso, Rosberg, Felipe Massa and Raikkonen.
Swapping to longer runs, many drivers complained about the left front tyres, which suffered serious graining. "That looks bad," was Nico Hulkenberg's assessment when he pulled into the pits while McLaren called the option tyre "pretty fragile."
It couldn't be more so though than for Pastor Maldonado who lost a wheel nut which resulted in his tyre rubbing against the car and suffering a failure. He was forced to park it on the side of the track, the only driver not to see the chequered flag in FP2.
Back in the action, the Red Bulls were looking strong on both the soft and medium tyres on the long runs with both Vettel and Webber's last laps on the mediums clocking inside the early 1:30s. Alonso was in the 1:33s on the soft tyres as was Raikkonen while on the mediums Rosberg was bouncing between 1:35s and 1:31s which was a worry for the team.
