Sebastian Vettel, who also now holds the record of being the youngest ever F1 world champion. Vettel had been in the hunt all year, but had never lead the championship until his win on the last race of the year. His closest rivals, which included his teammate Mark Webber and Ferrari-ace Fernando Alonso, had an unusually bad race, which just played in favor of the young German.
With many technical changes planned for the 2011 F1 season, it will be interesting to watch which team will get their package right next year. I just hope Michael Schumacher will have a better year.
