Presented in June 1991 near Modena, the Grifo 90 was an attempt to revive the Iso marque by Piero Rivolta and Piero Sala. Powered by a front-mounted turbocharged 5.7-liter Chevrolet V8 (tuned by Callaway) with 440bhp driving the rear wheels through a six-speed gearbox, only one (non-functioning) example was ever built. The aluminum body was fitted to a tubular steel chassis frame. Double wishbones and disc brakes were fitted all around. Both Gandini and Dallara were involved in the car's design, which was predicted to exceed 300km/h and need a mere 4.5 seconds to reach 100km/h.
