The Mercedes, McLaren, Force India have looked quick with Kubica's Renault, the Red Bulls and Ferrari not too far behind. This season looks to be pretty exciting as refuelling has been banned (cars will have to overtake on track instead of in the pits as a consequence of this
), new teams have entered (return of Lotus & Sauber 
, Virgin F1 have entered alongside Hispania F1 aka Campos who have Bruno Senna) and there are a few wacky aero packages (notably McLaren). Anyway it promises to be a stellar season, so enjoy!
Vettel's brakes break whilst he was leading. Button won by making a brave early pit stop and looking after his tyres. Hamilton got into 3rd but then made a second stop, which put him back into 5th but made him faster than the cars in front. But he was struggling to get past Alonso in 4th place, and then Webber ran into the back of him on the penultimate lap. He managed to get to the finishing line in 6th, but wasn't happy with his team for bringing him in for the extra change.
