The Iso Grifo was a grand tourer manufactured by Italian automaker Iso Autoveicoli S.p.A. between 1965 and 1974. Designed to compete with the likes of Ferrari and Maserati, it utilized a range of American powertrains and components from Chevrolet and Ford. The car's styling was the work of Giorgetto Giugiaro at Bertone, while the mechanicals were handled by Giotto Bizzarrini. The first production GL models were introduced in 1965, powered by American Chevrolet small-block 327 (5.4-liter) V8 engines mated to Borg-Warner 4-speed manual transmissions. The 5.4-liter engine produced 300 horsepower (220 kW) in its standard form, allowing the car to reach a speed of 110 km/h (68 mph) in first gear. In 1970, the Grifo Series II was introduced, featuring updated styling and hide-away headlights, along with big-block Chevrolet 454 V8 (7.4-liter) engines. This was later replaced by the Grifo IR-8, which used a small-block Ford Boss 351 engine (5.8-liter) as its powertrain. Unfortunately, the manufacturer went bankrupt in 1974, and the Grifo became the last new Iso of any kind. Several factors led to the bankruptcy, including the 1973 oil crisis, which reduced demand for cars with large displacement engines.
