World-famous auto designer Brook Stevens designed this car for 1964 and also redesigned the 1962 Gran Turismo Hawk. In 1961 Studebaker purchased Paxton Products, with head man Andy Granatelli to set up their performance program. In August 1962 and September 1963, Studebaker set 337 land speed records at Bonneville. All records are official as sanctioned, timed, and certified by the United States Auto Club (USAC).

The eight-cylinder engine had a 259.2 cubic-inch displacement, a cast-iron block, solid valve lifters, a Stromberg two-barrel carburetor and delivered 180 horsepower at 4,500 RPM. The Studebaker Hawk, Cruiser, and Marshal were equipped with a 289 CID V8 that developed 210 horsepower. With the R1 package, in un-supercharged form, the 289 CID V8 had 240 horsepower. With the addition of a supercharged, it developed 289 hp.

The 1964 Studebaker sedan and station wagons rested on a 120.5-inch wheelbase platform, while other body styles had a 109-inch platform. Optional equipment included power brakes, reclining seats, backup lights, a Day-Night interior rearview mirror, bumper guards, an electric clock, exhaust deflectors, and more.

The styling of the Series 64V (eight-cylinder models) was similar to the six-cylinder models, visually distinguished by model identification and '8' emblems. Hardtops and Daytona sedans had crossed checkered flag V-8 emblems located on the upper rear quarter panels.

1964 Studebaker models included the Daytona, Challenger, Commander, Gran Turismo Hawk, and Avanti.
