The Texas Motorplex is a quarter mile drag racing facility located in Ennis, Texas, United States, 40 miles south of downtown Dallas. Built in 1986 by former funny car driver Billy Meyer, the Motorplex was the first National Hot Rod Association (NHRA) "super track." It annually hosts the AAA Texas NHRA FallNationals each October, when hundreds of professional and amateur drag racers compete for over $2 million in prize money.
