Cien concept car honors Cadillac's centennial

The V12-powered Cien is a glimpse at what a future halo car for Cadillac could be, particularly under the hood, and is also a memento of Cadillac's 2002 Centennial celebration - "cien" means 100 in Spanish.

The V12-powered Cien is a glimpse at what a future halo car for Cadillac could be, particularly under the hood, and is also a memento of Cadillac's 2002 Centennial celebration - "cien" means 100 in Spanish.

Cien's 7.5-liter V12 powerplant, which is visible through the car's rear window, is a new concept engine from GM Powertrain dubbed the Northstar XV12. The all-aluminum, DOHC engine generates 750 horsepower and 450 lb-ft of torque, yet meets the packaging requirements and fuel economy standards of a V8. The Cien, with its low, sleek appearance, is constructed from high-tech materials such as carbon fiber, composites and aluminum.
