NASCAR’s First Big Next Gen Oval Test Was a Rocky Start

NASCAR completed its largest test of the brand-new Next Gen Cup car at Charlotte Motor Speedway’s oval last week. The results? A lot of promise on many technical aspects, but a need for improvement in how the cars interact with each other in traffic.

The Charlotte oval test was the debut of a number of changes to try to alleviate cockpit heat with the Next Gen car. The changes appear to be working, but some had an impact on handling.

The first day of testing showed that the cars were a couple seconds slower around the Charlotte oval than the outgoing Generation 6 cars. Variables like engine power, weight, and the aerodynamics all played a part. But the changes made to reduce temperatures in the cabin–like the rear window slits–also had an impact on the aerodynamics which further slowed them down.
