Cadillac Cien

The Cadillac Cien was a concept car created by Cadillac and unveiled at the 2002 Detroit Auto Show. The Cadillac Cien had a 7.5 L V12 Northstar XV12 engine, which produced 750 hp. This experimental engine featured direct injection and Displacement on Demand, which allowed the engine to run on only six cylinders under light load. The Cien was designed at General Motors Advanced Design Studio in England and built as a fully-working road-going vehicle with the help of the UK-based engineering and motorsport company Prodrive. The Cien's low, sleek style was inspired by the F-22 Raptor.

The car was featured prominently in the 2005 film, The Island, directed by Michael Bay. It was also in Gran Turismo 4, Midnight Club 3: DUB Edition, and in Midnight Club 3: DUB Edition Remix.
