Red Bull Racing's Sebastian Vettel has conceded his off in free practice two today at Abu Dhabi's Yas Marina Circuit was his own fault, as he just went too far on to the kerb.

Vettel went off when he lost control at turn one and slid sideways into the barrier. Although he was unable to extricate the RB7 from the wall, the double world champion was able to resume his session once the Red Bull mechanics had returned the car to the pits.

Having been fourth fastest this morning in FP1, Vettel eventually ended the day sixth on the timesheets, his best lap a 1 minute 40.132 seconds, 0.546 seconds off the pace.

"I had an incident in P2. It wasn't too much, I lost the car on the entrance to Turn 1. I think I was too wide and too far on to the kerb, so I lost the rear and couldn't catch the car anymore," he explained.

"I was lucky to get out again at the end of P2; there wasn't much damage apart from the front wing. If you just touch the kerb there, then it's fine, but I went too far on to it. Looking to the car, we are there or thereabouts - but it will be tight tomorrow I think."

Team-mate Mark Webber meanwhile was second in FP1 and fifth in FP2, his quickest lap a 1m 40.104s.

"It looks easy to get it wrong on Turn 1, when you see guys of the calibre of [Fernando] Alonso and Vettel getting out of shape, then you give a bit of a margin and come back up to it," Webber said.

"All in all, it was a pretty good afternoon and night for us and we got all the laps done that we needed to. I won't predict anything, as we know on Sunday that things can change, but we're going pretty well and I feel happy with the car," he added.
