Four

Four is a track in.

As the name implies, this track is shaped like a '4'. There is one large crossroad in the middle of the '4' where there's a ton of carnage. Getting points is very easy as a result, but the chance of being wrecked is also very high.

In Wreckin' Racing mode, you must score 2200 points to win the race, and completing this track unlocks the fourth bonus cars: Taxi Cab.

Trivia

 * On one end of the track, there's a pole with a Lightning without wheels on it. On another end there's another pole with a purple car attached to it, which looks like a Chevrolet Corvette (C2).
