From the liner notes

Ambitious, unique, and one of the quintessential films of the '70s, this is the cross-country car race between GTO (Oates), the Driver (Taylor) and the Mechanic (Wilson). Filled with incredible music and startling cinematography, this remastered, letterboxed video is a must-have. Oates, who won a few acting awards for his performance, is outstanding; and, yes, this is probably the first time you saw a film character sing along with his car radio, which now has become a cliché.
