Lewis Hamilton led a McLaren 1-2 at the Turkish Grand Prix on Sunday after a run-in between teammates Mark Webber and Sebastian Vettel denied Red Bull a sweep.
The Red Bull pair touched as Vettel looked to pass along the Istanbul Park Circuit's fastest section, causing the German driver to spin out of the race. Webber, who had led for the entire 40 laps to that point, recovered for third behind Jenson Button as Red Bull's pit-lane team looked on in astonishment.
The McLaren team also tensed up near the end as its drivers exchanged the lead but Hamilton eventually earned his first win of the season by 2.6 seconds after rain had sprinkled the circuit. "It was quite an exciting race," said Hamilton, the 2008 champion.
Webber leads Formula One's driver standings with 93 points, while Button moved into second with 88 points - four more than Hamilton. Fernando Alonso of Ferrari finished eighth to improve to 79 points and Vettel stayed on 78.
Webber had won the last two races from pole but finished 24.2 seconds back this time.
While the two leading teams battled for podium order, Mercedes, Ferrari and Renault fought behind them as Alonso worked his way up from 12th. Adrian Sutil of Force India was ninth while Kamui Kobayashi picked up Sauber's first points of the season with a 10th-place finish.
