If a car is given a score out of ten, with the only real way to judge it being to compare it to the cars around it and assuming that the RB7 is perfect, which I'm happy to say it is, then technically and after being rounded off to the nearest half, this is how the cars should score:
(don't take my word for it though - I just scraped my way through maths at school )
Red Bull RB7 - 10
McLaren MP4-26 - 9
Ferrari 150 Italia - 8
Mercedes MGP W02 - 7.5
Renault R31 - 6.5
Force India VJM04 - 6
Sauber C30 - 5
Toro Rosso STR6 - 4
Williams FW33 - 3
Lotus T128 - 2.5
HRT F111 - 1.5
Virgin MVR02 - 1
If you look at it that way then McLaren built a really good car for 2011, it just wasn't good enough!
Mercedes didn't do too badly either, for their 2nd year, building a car that's a 7 and a half out of ten.
