While they are all motorsports, Formula 1 is different to IndyCar and NASCAR. While IndyCar and Formula 1 are somewhat similar (both are single-seater, open wheel racing), Formula 1 operates on a stricter team basis. There is a lot of co-operation between teammates, the pit crew, and team principles. NASCAR is quite different to F1 and IndyCar as it is a stock car racing series. NASCAR tracks are generally oval-shaped and many more cars compete in the race than in F1 or IndyCar.
