fully behind the rear axle. The transaxle was from a Miura, with a higher final drive ratio of 5.30 to improve acceleration. The Marzal chassis was based on the production Miura chassis, extended by and stiffened. The resulting wheelbase was . The front hood was made from aluminum with the remaining non-glazed bodywork constructed from steel. Gross weight was . When visiting Bertone in the spring of 1967, journalist L.J.K. Setright observed that "five large blocks of metal and a moderately small anvil" had been placed in the front compartment of the Marzal in order to level the ride height from front to back. Overall length was , width and height . The suspension, steering and brakes used in the Marzal were all taken from the production Miura. Suspension travel was limited compared to the Miura, due to the design of the bodywork. Bertone designed unique 14 in diameter by 6.5 inch wide magnesium centerlock wheels, made by Campagnolo. These were similar in construction to those used on the Miura and Espada, but were visually unique, with two rows of nearly-hexagonal air ducts. Pirelli Cinturato HS tires in size 205-14 were fitted. In total, of glass paneling was used in the Marzal, all supplied by Glaverbel. This company had previously provided Bertone with the glass used in the Alfa Romeo Carabo and the Miura's rear window. An air conditioning system was installed in order to deal with the resulting high passenger compartment temperatures. References Marzal Bertone concept vehicles
