Newly-crowned world champion Sebastian Vettel resumed normal service as he topped the second practice session for the Abu Dhabi Grand Prix.
Once again, the Red Bulls were able to shave a couple more tenths off their lap times than their competitors when it came to running the soft compound tyres and Vettel finished the session 0.155s ahead of team-mate Mark Webber. Lewis Hamilton was Vettel's closest non-Red Bull rival with a time 0.355s off Vettel and just a fraction ahead of Kimi Raikkonen in fourth. Nico Rosberg was 0.432s shy of Vettel's best lap, while FP1 pacesetter Romain Grosjean failed to set a representative time due to a problem with his car.
Midway through the session, Grosjean ran straight on at one of the chicanes before reporting over the radio that he had a problem with his Lotus. When he returned to the pits the team set to work on his front-right brake, but Grosjean brought the car back to the pits again before the end of the session, missing out on roughly 20 laps of running.
He was not the only one to have car issues after a bit of Max Chilton's Marussia fell off around Turns 11, 12 and 13 and both Paul di Resta and Jenson Button suffered punctures. Di Resta had a front-left puncture while Button had a slow puncture on his right rear. Hamilton also complained of a funny feeling in his Mercedes before the session was out.
McLaren's recent improved form looks as though it has carried over to Abu Dhabi as Sergio Perez went sixth fastest and Button was seventh. Both were quicker than Fernando Alonso in eighth place as Ferrari looks set for another tricky weekend. Nico Hulkenberg and Felipe Massa rounded out the top ten.
While Red Bull was strongest on high fuel too, the worry for Ferrari will be its long run pace. McLaren's improvement put it on a par with the Mercedes and Lotus, but Ferrari was slightly off those times.
