 USAC NM/AZ Regional Sprints Car Specs

With engines producing upwards of 800 horsepower, these 1200 pound rocket ships combine the thrill of raw power with the heart stopping action of non-wing sprint car racing. Dirt rooster tails, wheel stands and three wide racing are the norm when these bad boys come to town. Sprint cars also run on paved tracks and any driver with aspirations of a championship must be able to negotiate both dirt and pavement.
