I am looking for a Motor sport movie?

i know there are thousands of motor sport movies but this one is about either champ cars, f1 car, or indycars (i was young when i saw the movie and it looked liked f1 cars but every open wheel race car looks like them when you are little) like most teams there were two drivers one much older one that in his introduction drive round the circuit humming and dropping coins that he later picks up on his rear tire. they also drive through the city in there cars at night. that is all i can remember but i really want to find out the name of the movie
