The Challenger was the entry-level model of the newly faced lifted line of 1964 Studebakers. Still having its rubber floor mat and the Spartan use of chrome trim, this was the ideal candidate for a performance Studebaker.

The power train consisted of the same Studebaker 289 cubic-inch V8, with Paxton Supercharger, that powered various models of Studebakers to land speed records at the Bonneville Salt Flats in 1964. The transmission was a Borg-Warner T-10 four-speed with a Dana 44 posi-traction axle, (Twin-Traction by Studebaker).

The suspension and brakes have been enhanced to accommodate the hard use of road racing. The challenger has performed trouble-free many times at Road Atlanta, competing in the Walter Mitty Challenge Series. It has been observed with a top speed of 135 MPH.
