NextGen car debut delayed until 2022
Amid the COVID-19 outbreak, NASCAR announced Thursday that the NextGen car’s debut will be delayed until 2022.
The NextGen car was set to make its debut in the 2021 NASCAR Cup Series season, prior to Thursday’s announcement.
“The decision was made in collaboration with the OEMs and team owners,” John Probst, NASCAR Senior Vice President of Racing Innovation stated.
“We will continue to develop the NextGen car, and a revised testing timeline will be shared when more information is available.”

Testing had already been conducted at Richmond with Austin Dillon, Phoenix with Joey Logano, Homestead-Miami with Erik Jones and Fontana with William Byron.
The postponement had already cancelled tests at Atlanta (March 16-17), Bristol (April 6-7), Dover (May 4-5) and the status of tests at Charlotte (June 2-3) and Las Vegas (July 14-15) are unknown with no word yet on how much longer postponements will go on.
