The Cadillac Cien has a longitudinally mounted 60-degree, 7.5-liter V12 that produced 750 hp (559 kW) and 650 lb⋅ft (881 N⋅m) of torque. The experimental engine featured direct injection and displacement on demand, which allowed the engine to run on only eight or fewer 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 monocoque chassis and body are made of aerogel composite and equipped with active aero.[3] Its design was inspired by the F-22 Raptor.[4]
Initially, there were plans to put it into production, but due to the lack of development funds and the high expected selling price of US$200,000, the existence of a customer base for the Cien was put into question. The production of the Cien was thus cancelled at a board meeting.[5]
In media
