Possible Gen-7 Car Tech Elements Featured At NASCAR All-Star Race

The Monster Energy NASCAR All-Star Race will feature two technical elements that could be incorporated into the Gen-7 car set for 2021.

NASCAR and Charlotte Motor Speedway announced the technical specifications and format Wednesday for the May 18 exhibition race at the North Carolina track.

The technical elements are a single-piece carbon fiber splitter/pan and a radiator duct that exits through the hood instead of the engine compartment. NASCAR said the splitter/pan will "provide a more stable aero platform and create more consistent performance in traffic." The radiator duct will "create improved aerodynamic parity and, at the same time, reduce engine temperatures."

The race will again have four stages, with a five-lap increase in the final stage from last year. The stages will be 30, 20, 20 and 15 laps. Both green- and yellow-flag laps will count in Stages 1-3, with only green-flag laps counting in the final stage.
