BMW Nazca C2

The Nazca project began in 1991 when the Nazca M12 was launched at the Tokyo Motor Show. The design was derived from the Bugatti ID 90 concept unveiled a year prior. The M12 was the first car designed by Giugiaro's son, Fabrizio and incorporated design elements from Group C race cars.[2] The car achieved a drag coefficient of Cd=0.26 when tested in the BMW windtunnel.

The car had a carbon fibre body construction also using the material for the construction of the space frame. Due to this, the car weighed a total of 1,100 kg (2,425 lb).

The engine cover and front of the car were made from a single piece of molded carbon fibre. The car had a glass engine cover which displayed the 5.0 litre V12 engine shared with the BMW 850i. The engine generated a power output of 300 hp (224 kW; 304 PS). The car had a unique door mechanism which had conventional doors and windows opening in a gull-wing arrangement.

A year later in 1992, the Nazca C2 was introduced. The C2 had a redesigned front (the headlamps were relocated beside of the kidney grille) and a modified engine. Italdesign had engaged the German automobile manufacturer Alpina into the project. Alpina modified the engine and as a result, the engine gained an additional 50 hp (51 PS; 37 kW). This engine was shared with the Alpina B12 5.0. Additionally, the C2 also had fixed racing seats and three spoilers at the rear to signify its race inspired status. The C2 also weighed a claimed 100 kg (220 lb) less than the preceding M12.[3]

The engine used was a modified version of the 5.0 liter V12 used in the BMW 8 Series tuned by Alpina. The engine originally generated a maximum power output of 350 hp (261 kW; 355 PS). The car had a top speed of 311 km/h (193 mph).

Three cars in total were produced including the M12. The car was intended as an official replacement for the BMW M1, but BMW was hesitant at producing another mid-engined sports car after the M1 had been a failure, so they pulled the plug. BMW allowed ItalDesign to use their name and grille solely on the 3 concept cars built.

BMW Nazca C2 Spider with the glass panels removed

At the 1993 Formula One Grand Prix held in Monte Carlo, Italdesign introduced a new, slightly redesigned version of the C2 called C2 Spider. The car had removable glass panels instead of the semi-gullwing doors featured on the coupe, turning it into a roadster along with a modified engine cover. The removable parts were housed in the luggage compartment in the front of the car and could be quickly reinstalled. A roll bar in the colour of the car was fitted in order to reinforce the chassis to compensate for the loss of removable glass panels. The intake manifold of the engine was redesigned in order to allow for open air operation. The car was fitted with a 5.7-litre V12 engine shared with the 850CSi. The engine generated a maximum power output of 380 hp (283 kW; 385 PS), a 6-speed gearbox was installed instead of the 5-speed gearbox of the coupe to better cope with the increase in the power.[3]
