CHARLOTTE, N.C. (AP) — NASCAR has fined Hendrick Motorsports $100,000 for exceeding the amount of wind tunnel testing allowed in a year. The organization has also been docked 10 hours of wind tunnel time for next year.

The testing is defined as billable hours reported by the wind tunnel. Hendrick Motorsports self-reported the violation after discovering it had exceeded 70 hours by “less than an hour.”
