In terms of how they get paid, NASCAR drivers are different from athletes in team sports.
Whereas NFL and NBA players receive the bulk of their 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.
One of the sport's all-time greats, Jeff Gordon, turns 50 on Aug. 4 -- and the racing legend is worth a cool $200 million. Let's mark the occasion with a challenge: Can you guess how rich each of these current NASCAR drivers is?
Last updated: Aug. 4, 2021
Denny Hamlin, 40, is a three-time Daytona 500 winner, including back-to-back victories in 2019 and 2020.
The Joe Gibbs Racing star has 44 career Cup victories. Despite leading the NASCAR point standings in 2021, he has yet to win a race as the regular season nears its close.
Hamlin has plenty of endorsements, including with Domino's and FedEx. Check out his total net worth here.
At 45, Kevin Harvick already has compiled a Hall of Fame-worthy NASCAR career. He won the 2014 NASCAR Cup Series championship and the 2020 regular-season title, as well as the 2007 Daytona 500.
Harvick has 58 career NASCAR Cup Series victories and 119 across all NASCAR race series.
Off the track, he has served as a race broadcaster for Fox, formed his own scholarship foundation and endorsed Jimmy John's, Mobil 1 and more.
Kyle Busch, 36, is a two-time NASCAR Cup Series champion (2015 and 2019), with 59 race victories.
The younger brother of Kurt Busch, Kyle is the all-time leader in NASCAR Xfinity Series victories with 102. He has 222 career wins across all three NASCAR series.
Known as "Candy Man" for his longtime association with candy manufacturer Mars Wrigley, Kyle drives a car with M&M decals.
Kurt Busch, 43, has dropped hints recently that he might retire after this NASCAR season. If he does, he will wrap up a stellar career, highlighted by the 2004 NASCAR Cup Series championship and the 2017 Daytona 500.
The versatile driver also won the 2003 IROC championship and raced in the Indianapolis 500, 24 Hours of Daytona and NHRA events.
Busch, known for feuds with other NASCAR drivers earlier in his career, has a big sponsorship with Monster Energy.
One of the greatest NASCAR drivers of all time, Jimmie Johnson has seven Cup Series championships and 83 career victories.
Known as "Seven-Time" for his record-tying seven championships, Johnson dominated NASCAR for most of the 2000s. Although he is semi-retired, he still drives occasionally for Chip Ganassi Racing and will participate in the IndyCar Series.
Johnson, 45, has been featured in video games and music videos, and he was sponsored for years by Lowe's.
Chase Elliott, 25, is the defending NASCAR Cup Series champion.
The son of former champion and NASCAR legend Bill Elliott, Chase first made his name by winning a Nationwide Series championship as a rookie in 2014.
He has 13 victories in Cup races, and he has a variety of off-course accomplishments, including the voice of character Chase Racelott in "Cars 3."
Bubba Wallace has the fewest race accomplishments of any driver on this list, with no Cup Series victories and a high finish of 22nd 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.
