These are the Formula 1 cars that are going to be racing in Singapore coming September. Found them while doing my research.
I can't really differentiate between them though.
These cars are the ultimate business marketing machines. Just look at the number of company logos on them.
BMW Sauber F1.08
Red Bull Racing RB03/04
Toro Rosso STR02
Force India VJM01
For more information on the team and drivers, just head on to the official website for the Singapore Grand Prix.
