McLaren - In a very good position, the car's good in a straight line and has a downforce advantage over the Red Bull, they're in a good position to fight for the title.
Red Bull - Need to work on qualifying pace, not far off in the race but may struggle at tracks where downforce is needed, compared to the McLaren.
Ferrari - Will struggle even more at Malaysia, just doesn't have the rear downforce of the McLaren, Red Bull, Mercedes or Lotus, Williams and Sauber will be right on them I'd expect.
Lotus - Can fight Red Bull if they hook everything up, a good qualifying at Malaysia could well mean a podium finish.
Sauber - Not far off Lotus, a great job by Perez after starting last shows that the car is there or there abouts, we'll have a better idea of their pace at Sepang.
Williams - Nip and tuck with Ferrari, would expect them to be fighting for 7th and 8th at Malaysia.
Toro Rosso - Should be fighting Sauber
Force India - Might just sneak ahead of Williams and Ferrari in the hands of Nico Hulkenberg.
Mercedes - A good qualifying car with the "super DRS" but it's eating its rear tyres, the harder compounds at Malaysia may favour them, but they've got work to do if they want to challenge for wins.
Catherham - A bit of a push and they could be closer to the midfield, but the gap between the midfield teams means its unlikely Caterham will luck into a point.
Marussia - A solid base, but not expecting them to challenge Caterham.
HRT - Hopeless.
