The Car of Tomorrow, sometimes called CoT or "Car of Today", is the car style for the NASCAR Sprint Cup Series. Larger and boxier than the design it replaced, the Car of Tomorrow is safer, costs less to maintain, and was intended to make for closer competition.^{[citation needed]}

The car was introduced in the 2007 Cup season at the Food City 500 on March 25 and ran a partial schedule of 16 races. The plan was to require all teams to use the new car in 2009, but NASCAR officials moved the date up to the 2008 season as a cost-saving measure.

On January 11, 2006, NASCAR announced the Car of Tomorrow after a seven-year design program sparked mainly by the death of Dale Earnhardt Sr. in a final-lap crash during the 2001 Daytona 500. The then-current cars were based on a design by Holman Moody first used for the 1966 Ford Fairlane. The primary design considerations were "safety innovations, performance and competition, and cost efficiency for teams."

The CoT has improved safety over the older car. The driver's seat has been moved four inches toward the center, the roll cage has been shifted three inches to the rear, and the car is two inches taller and four inches wider. Larger crumple zones are built into the car on both sides. The splitter is a piece of fiber-reinforced plastic (FRP, "fiberglass") used on the bottom front of the car to produce downforce, replacing the valance. The car's exhaust exits on the right side, which diverts heat from the driver. The fuel cell is stronger, and has a smaller capacity 17.75 US gallons (67.2 L), down from 22 US gallons (83 L), which as of 2007 has become standard in all cars.

Brett Bodine (born January 11, 1959) is a former NASCAR Winston Cup Series driver and is the current driver of the pace car in Sprint Cup events. Brett is the younger brother of 1986 Daytona 500 winner Geoff Bodine and the older brother of 2006 Craftsman Truck Series champion Todd Bodine. He was born in Chemung, New York.

Bodine attended Alfred State College and received an associate's degree in mechanical engineering before he became a professional race car driver. Growing up watching his brother Geoff race in the modifieds, Brett decided to embark on a racing career on his own. He began in hobby stock races at the track owned by his parents in 1977 before moving up to the modifieds in 1979. That year he finished 33rd in the season long points race. In the 1980 season he moved up to 24th overall. The 1983 season was Brett’s most successful in the modifieds as he recorded 56 starts, 6 wins, 20 top fives, and 30 top tens in route to 7th in the overall standings. He also won his first NASCAR Modified National Championship event, the Stafford 200. 1984 was the last full season of modified driving duties for Bodine. He started 39 events, winning 3 with 19 top fives and 29 top tens while finishing 12th in the overall standings. He also won another National Championship event, this time at Oxford Maine.
