Legends car racing is one of the fastest growing and most affordable types of American motorsports. Powered by a motorcycle engine, a Legends Car is a purpose-built race car designed to resemble the legendary American automobiles of the 1930s and '40s. Drivers range in age from 12 to 65+ years old.

During the 2013 season, NHMS expanded its legends car racing into two series operated by the speedway as a part of U.S. Legends Cars International.  The cars race the Moat Mountain Road Course Series on the 1.6-mile road course and the Sign Works Oval Series on the 0.25-mile mini-oval.

The Granite State Legends Cars dealership emphasizes the growth of developmental racing at NHMS.  The on property store opened in September 2012 and is located in the S1 parking lot.  It sells everything needed to begin a racing career in either legends or bandoleros.

Drivers can track their live times at the track by downloading the Race Monitor app.
