Compete for the best lap time in your street or race car!
In NASA Time Trial competition, anything goes, from prototype racecars and converted production cars to the current crop of electric cars. Weight-to-horsepower ratios make for fair classes and lots of creative freedom to build the car you want.
NASA Time Trial provides a venue for spirited on-track competition with a high degree of safety and convenience. NASA Time Trial allows qualified individuals to compete in a “best lap time” format in a prepared car in advanced level open-passing sessions, and bridges the gap between NASA HPDE 4 and wheel-to-wheel racing.
