NASCAR's Hendrick Motorsports was fined $100,000 on Thursday after self-reporting itself on excessive wind-tunnel testing time.
Teams were allocated 150 hours of wind-tunnel testing time for Gen-6 vehicles to use in 2020 and 2021. It was split up into a maximum 70 hours for this year and a maximum 90 hours for next year.
While the overage time was determined to be less than an hour, and it was brought to NASCAR's attention, the fine and a 10-hour loss of 2021 testing time still was doled out as the penalty.
The infraction was considered a L2-level penalty and was in violation of Sections 5.3e of the NASCAR Rule Book.
Crew chiefs on the NASCAR Xfinity Series and NASCAR Trucks Series also were fined for loose lug nuts in a post-race inspection. Bruce Schlicker, crew chief for Ross Chastain's No. 10 Xfinity car, was fined $5,000 and Kevin Bellicourt, crew chief for Derek Kraus' No. 19 truck, was fined $2,500.
