There isn’t one fixed worldwide number, because “car racing divisions” can mean different things depending on how you count them. A practical answer is that there are at least 9 major divisions commonly recognized in auto racing, including Formula/open-wheel, sports car, stock car, touring car, drag racing, production-car, off-road, rally, and IndyCar-style open-wheel racing.

Why the number changes

Different sources split the sport differently. Some treat Formula and IndyCar as separate divisions, while others group them both under open-wheel racing; some also separate production-car racing from touring car racing, while others combine them.

Common major divisions

  • Formula/open-wheel racing.
  • Sports car racing.
  • Stock car racing.
  • Touring car racing.
  • Drag racing.
  • Production-car racing.
  • Off-road racing.
  • Rally racing.
  • IndyCar/open-wheel racing.

Quick takeaway

So the best short answer is: about 9 major car-racing divisions worldwide, but the exact count depends on how broadly you define “division.”
