Cadillac Cien

The Cien's low, sleek appearance, inspired by the latest F-22 Stealth fighter aircraft, has produced a

different look and proportion for Cadillac. It further demonstrates the reach of the brand's identity

Cadillac Cien's 7.5-liter, V12 powerplant, which is visible through a clear window in the decklid, is a new

concept engine from GM Powertrain named the Northstar XV12. The all-aluminum, dual overhead cam (DOHC)

four-valve V12 engine generates 750 horsepower and 450 lb.-ft. of torque, yet it meets the packaging

requirements and fuel economy standards of a V8.












The Northstar XV12 concept engine features several technological advancements over today's V8 engines,

including: GM's Displacement on Demand technology, which allows the engine to run seamlessly on six cylinders

at times to maximize fuel savings; direct injection gasoline combustion system for increased engine power,

improved fuel economy and reduced emissions; and a combined starter generator.

The Cien is fitted with a semi-automatic transmission, controlled by Formula 1-inspired column-mounted

electronic paddles.
