Where an NFL or NBA player receives the bulk of his income from a signed contract with a team, a NASCAR driver's money comes from a combination of salary, purse winnings from races and endorsements.

Bubba Wallace
Bubba Wallace has the fewest race accomplishments of any driver on this list, with no Cup Series victories and a high finish of 20th in the Cup standings in 2020.
But off the track, Wallace's accomplishments rank with the best in the sport. The 27-year-old is the only African American in NASCAR, and he was at the forefront of helping the racing circuit confront racism. Wallace drove a car with a special paint scheme to honor Black Lives Matter, and his fellow NASCAR drivers walked with him in solidarity after a noose was found in his garage.
Wallace now drives for a team owned by NBA legend Michael Jordan.
