The Nivola was a concept car produced by the Italian design house Bertone, first shown at the Geneva Motor Show in 1990. Its name was the nickname of Tazio Nuvolari, one of the most celebrated racing drivers of the 1930s, who was known for wearing a yellow pullover during races. Bertone chose the name in his honor and selected yellow as the color for the car in reference to that habit.
The Nivola was conceived as a two-seater, mid-engined coupe with a removable roof panel that allowed it to be converted into an open car. The roof, when detached, could be stowed in a compartment above the engine bay. The design followed a fluid, continuous line from front to rear, with the roof section notably recessed compared with the bodywork below the beltline. The nose sloped sharply downward and housed pop-up headlights, while air intakes for engine cooling were positioned in the flanks beneath the high-set doors and on either side of the rear deck. The rear lights were set into a distinctively shaped groove running around the tail of the car.
A particularly original feature was the design of the doors, which doubled as luggage compartments. Their outer skin could be opened from outside to access storage space built into their considerable thickness, an idea likened to the side pouches carried on motorcycles, though here concealed within the bodywork. The interior was designed for roominess and comfort and included seats with built-in massage vibrators in the seat cradles, a feature justified with reference to orthopedic specialists who suggested it could ease fatigue and stress on long journeys. Cabin colors were chosen to enhance the sense of space and light inside the car.
Mechanically, the Nivola was built around the running gear of the Chevrolet Corvette ZR-1, using its 5732 cc V8 engine with double overhead camshafts and 32 valves, producing 380 hp at 5800 rpm and 502 Nm of torque at 4800 rpm. Rather than being mounted at the front as in the Corvette, the engine was relocated behind the cockpit in a longitudinal mid-engine position and mated to a new five-speed ZF gearbox in place of the Corvette's six-speed unit. This was the seventeenth mid-engined design produced by Bertone, following earlier efforts including the Lamborghini Miura and the Bertone X1/9, and required extensive redesign of the chassis, suspension, and other mechanical systems to adapt components originally engineered for front-engine installation.
The chassis consisted of a tubular frame built from square-section, ultra-high-strength 25 CD 4 steel, chosen to combine low weight with high torsional rigidity. The Corvette-derived suspension was modified and supplemented with an electronically controlled hydropneumatic system developed by Way Assauto, part of the ITT group, which used an elastic spring element combined with an air cushion contained within the shock absorber to maintain consistent ride height regardless of load. Bertone enlisted Formula 1 specialists from Nova Progetti and Albatech to assist with chassis tuning. The Bosch ABS braking system from the donor Corvette was retained, as was the original braking hardware and wheel design, while the transmission ran through steel half-axles fitted with constant-velocity joints.
Positioning the engine behind the cockpit and angling the radiator at the front of the car helped achieve a weight distribution of 40 percent front and 60 percent rear. The car's kerb weight was not disclosed, though performance figures for its engine donor were cited for context: a standard Corvette ZR1 could accelerate from 0 to 60 mph (96.5 km/h) in 4.3 seconds, compared with 4.56 seconds for a Ferrari F40 over the 0-100 km/h sprint. The Nivola rode on colored wheel rims fitted with Michelin XGT tires measuring 245/40 x 17 at the front and 315/35 x 17 at the rear; front rims measured 8 x 17 inches and rear rims 11 x 17 inches.
In terms of dimensions, the Nivola measured 420.5 cm in length, 198 cm in width, and 110 cm in height, with a wheelbase of 255 cm and track widths of 155 cm at the front and 160 cm at the rear. Front overhang measured 91 cm and rear overhang 74.5 cm. Compared with the standard Corvette ZR1, which measured 450.5 cm long, 188 cm wide, and 118.5 cm high, the Nivola was notably shorter, wider, and lower despite having a wheelbase 10.5 cm longer than the Corvette's.
The Nivola remained a prototype and was never put into production. It was built, in keeping with Bertone's practice for its concept vehicles, to be fully functional and capable of being driven on the road rather than serving purely as a styling exercise. It was presented as part of a line of Bertone concepts that included the Athon, the Zabrus, and the Genesis, each exploring different aspects of advanced design and engineering. Some earlier Bertone designs, including the Miura, the Carabo, the Stratos, and the Countach, were noted as having been displayed at an automobile design exhibition at the Georges Pompidou Centre in Paris.
