2021 Petit Le Mans

The 2021 Petit Le Mans (known as the 2021 MOTUL Petit Le Mans for sponsorship reasons) was the 24th running of the Petit Le Mans, and was held on November 13, 2021. It was the 12th and final race in the 2021 IMSA SportsCar Championship, and the 4th race of the 2021 Michelin Endurance Cup. The race was held at Road Atlanta in Braselton, Georgia. This race was the last ever race for the GTLM Class.

Background
International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2021 IMSA SportsCar Championship (IMSA SCC) in September 2020. It was the eighth consecutive year it was part of the IMSA SCC, and 24th Petit Le Mans. The 2021 Petit Le Mans was final of 2021's IMSA sports car endurance races, and the last of four races of the Michelin Endurance Cup (MEC). The race took place at the 12-turn, 2.540 mi Road Atlanta in Braselton, Georgia.

The 2021 running marked the event's return to the final calendar spot on the schedule following the wholesale schedule changes that resulted from the COVID-19 pandemic in 2020. The 2021 edition underwent a date change of its own, being postponed from its traditional early-October spot to the weekend of November 13th. The event featured support from four of IMSA's supporting series; the Michelin Pilot Challenge, IMSA Prototype Challenge, Porsche Carrera Cup North America, and Mazda MX-5 Cup.

On November 3, 2021, IMSA released the latest technical bulletin outlining Balance of Performance for the event. In GTLM, the Chevrolet Corvette C8.R received a one-liter reduction in fuel capacity, while in GTD the 2021 debut of the McLaren required its addition to the BoP table.

This would be the final race for entry Mazda Motorsports as Mazda was stepping back from all racing activities following the 2021 season with the exception of the Mazda MX-5 Cup. Also making its farewell was the GTLM class which in 2022 would be replaced by the new GTD Pro class.
