Sebastian Vettel cruised to victory at the Turkish Grand Prix after leading from the start to the chequered flag.
Red Bull Racing team-mate Mark Webber and Ferrari's Fernando Alonso completed the podium after an action-packed race where the leader board seemed to change by the second.
Alongside Vettel on the podium were Mark Webber and Fernando Alonso. Alonso also put in a solid performance and initially seemed to have the measure of Webber. But Webber then hit back over the last few laps to reclaim the second place he had surrendered to Nico Rosberg in the first 100 metres of the race.
Rosberg meanwhile had a rollercoaster race, finishing in fifth place behind Lewis Hamilton. The Mercedes initially struggled for race pace and Rosberg was losing position after position. He changed to hard tyres early in the proceedings and then switched back to soft for the final stint when his closest competitors had gone onto the hard 'primes'. This enabled him to claw his way back up the field.
Hamilton had his work cut out. As well as fighting a sequence of remarkable duels with Felipe Massa, Jenson Button and Rosberg, he also had to cope with the loss of around 15 seconds on a botched pit stop. Jenson Button was one of only a few in the leading group to try a three-stop strategy. In the end, though, there was a price to pay as Hamilton and Rosberg on their four-stop strategies sailed past to consign him to a P6 finish.
The other Top Ten points-scoring positions were filled by Nick Heidfeld, Vitaly Petrov and Sebastien Buemi, plus Kamui Kobayashi who had started from the back. Petrov was in the thick of the action on two occasions, first when he clipped Michael Schumacher's front wing and later when he almost forced team-mate Nick Heidfeld into the pit lane. Schumacher's race was severely compromised by the pit stop to change the nosecone, but he kept battling away. The former champion was overtaken on several occasions as the tyres began to degrade, but then he began to turn the screw himself.
Schumacher ultimately crossed the line in twelfth position behind Felipe Massa. Sergio Perez came twelfth after also having to stop for an unscheduled nose job and was followed by Adrian Sutil, Rubens Barrichello and Jaime Alguersuari. Pastor Maldonado finished 17th, marking another mediocre Sunday outing for Williams. The also-rans were Jarno Trulli, Heikki Kovalainen, Jerome D'Ambrosio, Narain Karthikeyan and Tonio Liuzzi. Paul di Resta had to retire from the race and Timo Glock failed to start because of a gearbox problem.
