About This Class
NASA Time Trial is a competitive solo-driving format where participants are timed on track and ranked against others with similar lap times. Time Trial bridges the gap between casual HPDE track days and wheel-to-wheel racing, offering a competitive framework without close-proximity racing. The format accommodates any car from a stock Miata to a fully prepared race car, with participants grouped by lap time to ensure fair competition. Time Trial is the most popular competitive NASA program by participation numbers.
