In NASCAR, drivers need sponsors to race, and those sponsorships often create iconic partnerships that become synonymous with the driver and their brand. Richard Petty was always driving the 43 STP car, Dale Earnhardt was the driver of the number 3 Goodwrench Chevrolet, and Jeff Gordon drove the 24 Dupont car. While it is fairly rare to see a sponsor work with a driver for a full season these days, there are still some pretty iconic partnerships in NASCAR.
