The National Auto Sport Association (NASA) is an American motorsports organization promoting road racing and high-performance driver education.

Founded in 1991,[1] NASA hosts High Performance Driving Events (HPDE), automotive rallies, Time Trial, autocross and amateur, club-level automotive racing, divided amongst regionally based chapters within the United States.

In September 2006, NASA held its first-ever National Championships at Mid-Ohio.

[2] Racing in the time trial classes allows drivers to compete against each other for the fastest lap.

It is currently NASA's mid-level offering, fitting between the HPDE and road racing series.
