F1 2012 Online Cars - Differences?

[Doc-Ric]

Being in a racing league, we are looking into differences in online cars (set to equal performance) to decide if some should be ruled out (like Lotus and Ferrari seemed slower in F1 2011..)
Taking into account different driving styles, we're thinking that Sauber (and possibly Williams) offer more power/top speed, I'm wondering if anyone has noticed these and possibly other differences.

(additionally, it seems some cars have slightly lower tyre degratation, but it seems offset by a slower tyre warm-up, so it could be a nice addition instead of a league-breaker )
