I did a bit of research and realised something quite interesting: 2011 could be the first season in the history of formula one where only world champions won races. Vettel (8), Button (2), Hamilton (2) and Alonso (1) have won this year, and if they manage to win the remaining races (and Schumacher can as well) it will be the first time ever this has happened.
Something similar happened in 1963 and 1993, where the only drivers to win races were world champions, but there’s one difference – in 1963 Surtees won, but he wasn’t a world champion yet – same goes for Clark. In 1993 it’s the same for Schumacher and Hill.
1950 and 1953 were only won by world champions if you exclude the Indy 500, though again, Fangio and Hawthorn respectively were yet to win a title (and Farina in 1950).
Back to 2011, Webber is probably the only driver who can do something about that, perhaps Massa and Rosberg as well. If Vettel, Button, Hamilton and Alonso win the remaining races it’ll be pretty special. Even more so as it’s the longest season in the history.
And with the top 5 in the Italian GP being only champions (first time ever), it arguably shows what a quality grid we have.
