The 1963 Studebaker Avanti is a personal luxury coupe celebrated as an avant-garde masterpiece and one of the most significant milestones of the postwar American automotive industry. Conceived by Studebaker president Sherwood Egbert as a high-performance "halo car" to rival the Ford Thunderbird, it was designed in a legendary 40-day crash program by industrial designer Raymond Loewy and his team. Marketed as "America's only four-passenger high-performance personal car," the Avanti combined advanced safety, striking jet-age styling, and blistering record-breaking speed.
Key Engine Variants & Performance
The Avanti was built on a modified Studebaker Lark Daytona convertible chassis but paired with cutting-edge powertrain options built for high-speed endurance:
- R1 (Naturally Aspirated): Powered by a 289-cubic-inch V8 engine delivering 240 horsepower. It used a Carter four-barrel carburetor and featured a 10.25:1 compression ratio.
- R2 (Supercharged): Equipped with a factory-installed Paxton centrifugal supercharger on the 289 V8, churning out 289 to 290 horsepower. The R2 is highly coveted by collectors, particularly when paired with the rare 4-speed manual transmission.
- R3 (High-Performance Supercharged): : A bored-out 305-cubic-inch version producing 335+ horsepower. Driven by racing legend Andy Granatelli at the Bonneville Salt Flats, modified R3 models smashed 29 world speed records, clocking speeds of nearly 179 mph.
