People have been talking about the difference between Vettel and Bourdais. I have to say that I’ve been vastly more impressed by Vettel’s performance this year.

But several commentators have suggested that this is only because Vettel has more experience than Bourdais.

Is this really true? Vettel has been in more F1 races than Bourdais. 8 more. But Bourdais has actually been racing in professional single seaters for many more years.

How many champ car seasons is the equivalent of an F1 race?
