Vettel fastest in final practice

Hamilton spun off at Turn Eight

Red Bull's Sebastian Vettel was quickest in the final practice session for the Turkish Grand Prix.

The German set a time of one minute 27.086 seconds, 0.273secs clear of Mercedes's Nico Rosberg in second.

McLaren's Lewis Hamilton was third quickest with the other Red Bull of Mark Webber fourth fastest.

Vettel, Webber, Hamilton and Ferrari's Fernando Alonso all lost control on the Istanbul Park track as they tested their cars' limits before qualifying.

Hamilton's spin off Turn Eight was the most spectacular and the 2008 champion had to return to the pits to replace his damaged tyres.

Webber, who was also pushing his Red Bull hard on the Turkish circuit, suffered problems with his throttle earlier in the session and had to coast into the pits for repairs.

But despite those problems and veering off the track on occasions, the Australian joint leader of the championship returned to post a quick time.

His team-mate Vettel, who shares the lead, will go into qualifying later on Saturday looking for his seventh straight pole position.

The German set the quickest time late in the practice session, closely followed by compatriot Rosberg who sneaked in a fast lap and trumped his Mercedes team-mate Michael Schumacher, who was seventh.

Alonso was sixth fastest with fellow Ferrari driver Felipe Massa, who has won in Turkey on three consecutive occasions, ninth.

Robert Kubica impressed in the Renault to claim the fifth fastest time with his team-mate Vitaly Petrov, who also lost control in the session, 10th quickest.
