F1 2013 Which is the best car in the career mode

[Feras Fadel]

we all know that in the game F1 2012 the Mclarens were the best car (the fastest a nd the easiest to drive)
but in the F1 2013 i can't really tell which is the best in the career mode..
i have been playing in a career mode and i noticed that Vetel in the red bull has the best times ,and Hamilton in the Merc comes second, but i really con not tell as i have been driving the Williams ,which was very slobby in races .. and i was promoted to the mclaren which is very easy to drive and feels great ..but my team mate Button has slow timings and comes 8th or 9th in qualifying..
so can u help me

I guess Ferrari is the faster together with Mercedes and REd bull even too, but the Ferrari seems a little step on them.
