Four different teams have won the 15 races so far this year (Lotus, Red Bull, Ferrari, Mercedes).
Triple champion Vettel has nine wins in 2013. Ferrariís Fernando Alonso and Mercedesís Nico Rosberg have won two races each. Lotusís Raikkonen and Mercedesís Lewis Hamilton have each won one. Vettel has won the last five races.
Vettel has 35 career wins, Alonso 32, Hamilton 22, Raikkonen 20 and McLarenís Jenson Button 15.
Ferrari have won 221 races since the championship started in 1950, McLaren 182, Williams 114 and Red Bull 43.
Red Bull can win both the driversí and constructorsí titles in India.
Vettel has a 90-point lead with 100 points still available to be won. If Alonso wins the race on Sunday, Vettel need only finish fifth to clinch his fourth successive title.
Alonso must finish in the top two to have any chance of keeping the championship alive to Abu Dhabi.
If Alonso finishes third and Vettel fails to score, the Germanís lead would be cut to 75 points with 75 still to be won. However, Vettel would take the championship on race wins since Alonso cannot match his tally even if he wins the last three.
If Alonso retires from the race, Vettel will instantly win the title regardless of whether he finishes or not.
At 26, Vettel will be the youngest quadruple champion.
Only three other drivers have won four titles: Germanyís Michael Schumacher (seven), Argentinaís Juan Manuel Fangio (five) and Frenchman Alain Prost (four). Schumacher and Fangio are the only ones to have won four in a row.
In the constructorsí championship, Red Bull have 445 points to Ferrariís 297 with a maximum of 172 still to be won.
Mercedes have been on pole eight times in 15 races. Vettel has taken six and team mate Mark Webber one.
Vettel has 42 poles to his credit and is third in the all-time list
