Maserati Mistral 4.0

1966 to 1970

Introduced at the Geneva motor show, it was to be the last evolution of the straight-6 engine family, which could trace its roots back to the 3500 GT and the A6 series before that, and even the pre-war 6CM Grand Prix car. Top speed reached 255 kph (158 mph), no doubt aided by the car’s light weight and aerodynamic body.

Side vents with a chrome surround adorned the car’s front wings. Towards the end of the production run alloy wheels, identical to those on the Ghibli were available to order. One of the 828 coupés produced during the total production run was delivered to Sir Peter Ustinov.
