The Golden Hawk was continued for the 1957 and 1958 model years, but with some changes. Packard's Utica, Michigan, engine plant was leased to Curtiss-Wright during 1956 (and eventually sold to them), marking the end of genuine Packard production. Packard-badged cars were produced for two more years, but they were essentially rebadged Studebakers, including Packard Hawk – the restyled Golden Hawk. The Packard V8, introduced only two years earlier, was therefore no longer available. It was replaced with the Studebaker 289 in³ (4.7 L) V8 with the addition of a McCulloch supercharger, giving the same output as the Packard engine. This improved the car's top speed, making these the best-performing Hawks until the Gran Turismo Hawk became available with the Avanti's R2 supercharged engine for the 1963 model year.
