2018 NASCAR Cup Series (Simpsonverse)

The 2018 Monster Energy NASCAR Cup Series was the 70th season of NASCAR professional stock car racing in the United States, and the 47th modern-era Cup series season. The season began at Daytona International Speedway with the Advance Auto Parts Clash, the Can-Am Duel qualifying races and the 60th running of the Daytona 500, and ended with the Ford EcoBoost 400 at Homestead-Miami Speedway on November 18, 2018.

The season marked the debut of the Chevrolet Camaro ZL1, which replaced the outgoing Chevrolet SS and became the first coupe-based Chevrolet stock car since the Monte Carlo SS was discontinued in 2007. This was also the last season for Kasey Kahne, who announced his intention to retire from racing at the end of the season and was forced to step away in early October 2018 after not being medically cleared to continue, as well as BK Racing who sold its equipment to Front Row Motorsports. It was also the final season Ford fielded the Fusion, replacing it with the Ford Mustang in 2019.
