Chevrolet will run a slightly different body next season in the Monster Energy NASCAR Cup Series in the final year of the Gen-6 platform.

The Camaro ZL1 will be replaced by the Camaro ZL1 1LE, which is based on the most powerful version of the current-generation Camaro.

“The ZL1 1LE is the highest performer within the Camaro production-car lineup,” Jim Campbell, Chevy’s U.S. vice president of Performance and Motorsports, said in a press release. “We took lessons from the production car and applied them to the new 2020 Cup car.”

While many of the stylings are similar, the Chevrolet press release states that the body was taken to a wind tunnel following a process that included computational fluid dynamics testing and reduced-scale wind-tunnel testing.

As it pertains to the current production model, the ZL1 1LE has lighter wheels and brakes, thinner rear glass and a fixed-back rear seat. That lessens the total weight by 50 pounds and is powered by a 650-hp supercharged LT4 powerplant.

The Camaro ZL1 was introduced to the Cup Series in 2018. It has not fared particularly well, winning only 11 races in 69 starts, falling well short of regularly taking on the Toyota Camry and Ford’s Fusion and Mustang nameplates.

The Bowtie brand has won a record 49 Cup Series manufacturer championships -- including 13 in a row from 2003-2015. Chevrolet drivers have also recorded a record 31 championships.

The 2020 season will mark the final time the Cup Series utilizes the current-generation race cars, moving toward a new platform replete with spec chassis and bodies in 2021 and a new engine formula to follow a year or two later.
