who is the best debutant this year

Lewis Hamilton has shown from the start that he has the potential to upset the established drivers, and is definitely one to be watched this season.

Lewis Hamilton is definitely the best rookie. After every race he finished on the winning podium and he shares the #1 spot with Alonso in standings. In my opinion, he is the next big thing in the world of Formula 1. Heikki Kovalainen didn't adapt very well yet, but I think he's also very talented, but not as close as Hamilton.

Yeah there is no doubt about it, Lewis Hamilton is one of the most exciting drivers to come into Formula1 racing for many years. He has worked very hard to get where he is today and i have no doubt he will be a future world champion.

must be lewis hamilton, he has shown that he can drive verry fast continious lap times, and can drive well under pressure of a 2 times world champion team mate (not that alonso deserved those titles, but that's another discussion.) heikki kovalainen made too manny mistakes in his debut race, it's too early to give some commentary on him I guess, we will see how he performs within 4-5 races. although, it's gonna be a great season!
