[JM]BMW Nazca C2

The BMW Nazca C2 (also known as Italdesign Nazca C2) is a concept sports car introduced at the 1991 Tokyo Motor Show. The car was designed by famed automotive design studio Italdesign, home of Giorgetto Giugiaro, and features a similar frontal design of a BMW. It was an evolution of the BMW Nazca M12 from 1991.

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. 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.
