SAO PAULO (AP) -- The Formula One season ends this weekend with champion Sebastian Vettel looking to set more records to cap an already impressive year.
At the Brazilian Grand Prix on Sunday, the Red Bull driver can equal Michael Schumacher's record of 13 victories in a year and match the nine consecutive wins of Alberto Ascari in the 1952 and '53 seasons.
Also, Mark Webber will bid farewell to F1. It's the final race before a series of driver changes at other top teams such as Ferrari, McLaren, Lotus and Williams.
The Brazilian GP will be the last race before significant engine changes revamp the series next year, meaning there's a chance the days of dominance of Vettel and Red Bull could be over.
