Sebastian Vettel headed the timing sheets of the third free practice session ahead of the Abu Dhabi grand prix.

The newly crowned four time world champion was followed by teammate Mark Webber as Red Bull again locked out the top two positions in the standings. The session got underway with a track temperature of 47 degrees Celcius; three degrees warmer than Friday’s first free practice session.

Several drivers including Lotus’ Romain Grosjean and Ferrari’s Fernando Alonso endured several off track excursions during the session but sustained no damage. Marussia’s Jules Bianchi was as fortunate as contact with the barrier brought a slightly premature end to his session. However, the Ferrari of Alonso looked a handful as the Spaniard was shown sawing away at the wheel of the car as the coaxed it through the corners around Yas Marina circuit.

Pastor Maldonado and Valterri Bottas ran the Williams with a revised exhaust system and both driver’s provided encouraging feedback. The system is a reversion to an ‘old-style’ system which sees the exhaust exit to top of the body work.

The qualifying simulation, run on the yellow walled soft tyres, revealed an average gain of 1,7 seconds but several drivers were able to gain more than two seconds during their run. Nevertheless, we are of course unaware of the different fuel levels that are being run by teams in practice sessions.

The Mercedes pairing of Nico Rosberg and Lewis Hamilton appeared as the best of the rest behind the Red Bulls. Interestingly, Mark Webber set the quickest first and second sector while Vettel came out tops in the final sector of the lap. Abu Dhabi has never been a happy hunting ground for the Aussie but Webber may yet prove Vettel’s stiffest competition in qualifying later on this afternoon.
