Sebastian Vettel has won the final grand prix of the 2013 Formula 1 season at the Interlagos circuit in Brazil.
The Red Bull ace led from lap two, eventually finishing ahead of team-mate Mark Webber, and Ferrari's Fernando Alonso in third.
The race in Brazil not only marks the end of the F1 calendar for this year, but also the end of Webber's F1 career. The Australian driver will now move to Porsche to compete in Le Mans prototype racing.
Webber started in fourth position on the grid, with Alonso and Mercedes' Nico Rosberg lining up ahead of him, and Vettel once again taking pole position.
Vettel got a poor start off the line, however, meaning it was Rosberg who led the field into the first corner. Further down the pack, Lewis Hamilton was forced to go defensive as Alonso filled his mirrors, eventually being demoted to fourth position as the Spaniard sped past. Meanwhile, at the very front of the field, Vettel was able to successfully overtake Rosberg to re-claim the lead into lap two.
It was a short race for Romain Grosjean, whose Lotus exploded in a cloud of smoke on lap four, forcing the Frenchman to limp back to the pits.
By lap six, Alonso had continued his pace through the field, passing Rosberg to take second place. Vettel had opened up a huge lead, however, and was running unopposed with 4.9 seconds seperating himself and Alonso. Rosberg's race continued to deteriorate as he came under attack from Hamilton, prompting concerns that his tyres may be suffering excess wear. A radio message from the Mercedes garage to Rosberg said: "If you have problems with the tyres, then don't hold up Lewis. If they're coming back, then push."
