Sebastian Vettel Red Bull 2011 Japanese Grand PrixSebastian Vettel has added yet another accolade by being voted as the best Formula 1 driver of the year in AUTOSPORT's team principals' top 10 rankings.

In the annual poll, Vettel emerged as a clear winner ahead of Jenson Button, with last year's winner Fernando Alonso dropping two places down to third.

The annual team principals' verdict is compiled by getting the top 10 driver rankings of every boss, which are kept secret, and then converting their rankings into the F1 points' system (25-18-15-12-10-8-6-4-2-1). The final scores are added up to discover which driver the team bosses overall believed had done the best job throughout the campaign.

Vettel is the first World Champion since Lewis Hamilton in 2008 to earn the top place in the drivers' rankings.

Red Bull Racing team principal Christian Horner said that it would have been wrong for any driver other than Vettel to have come out on top on the back of his dominant campaign.

"It would have been a surprise if any driver other than Sebastian would have been voted as the driver of the year, after the season he's had in 2011," Horner said. "He won 11 races, finished second in five, third in one, had a fourth place and one DNF which is quite a remarkable run of results.

"On top of which, he scored a season record of 15 pole positions to secure his second consecutive World Championship title. Therefore he fully deserves to have been recognized as the outstanding driver of 2011."

Paul di Resta was the leading rookie driver, earning 44 points to take seventh place, while Heikki Kovalainen's efforts for Team Lotus were rewarded with ninth place.

This year's voters were: Horner, Martin Whitmarsh, Stefano Domenicali, Ross Brawn, Eric Boullier, Frank Williams, Vijay Mallya, Peter Sauber, Tony Fernandes, Colin Kolles and John Booth. Scuderia Toro Rosso declined to take part.
