The BMW Nazca C2 (also known as Italdesign Nazca C2) was a 1992 concept sports car.
 The car was designed by famed automotive engineering company Italdesign, home of Giorgetto Giugiaro, and features a similar frontal design of a BMW.
 It was an evolution of the previous concept the Nazca M12 from 1991.
 The engine used was a modified version of the 5.0 liter V12 used in the BMW 8 Series tuned by Alpina.
 It originally had 380 HP.
 The car had a top speed of 193 mi/h .
 Three cars in total were produced.

 The car was intended as an official replacement for the BMW M1 super car from the '70s - '80s, but BMW was hesitant at producing another mid-engined super car after the M1 flopped, so they pulled the plug.
 BMW allowed ItalDesign to use their name and grill solely on the 3 concept cars built.
