Cadillac Cien

In keeping with the brand’s role as a technology flagship for General Motors, the premium V12-powered Cadillac Cien concept car is a befitting icon to usher in the brand’s 100th anniversary in 2002. The striking, aerodynamic Cien – Spanish for 100 – holistically illustrates Cadillac’s fusion of design and technology in a modern mid-engine, two-seat supercar.

Cadillac’s design philosophy incorporates dramatic proportions and clean dynamic surfaces. It reflects not only the technology found within the vehicle, but also the technology used to create it. 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. Trapezoidal air inlets are milled into the front-end surface of the Cien, graphically forming Cadillac’s shield-like grille, which incorporates a centrally mounted wreath and crest insignia. These air inlets -- which feed the front-mounted radiators -- are flanked on either side by vertical headlamps, together creating the unmistakable ‘face’ of Cadillac. The body and monocoque chassis are produced from carbon fiber composite, derived from race car technology, that is both lightweight and strong. Electronically controlled air inlets and outlets are integrated into the Cien’s body side. These active vents open and close as required for cooling. Also, air is directed to the V12 engine via intakes beneath the two characteristic sail panels.

Nestled between the 19-inch front and 21-inch rear wheels is a cabin featuring high-tech structural materials and Cadillac’s leading-edge technologies: Night Vision, OnStar, StabiliTrak, Ultrasonic Rear Parking Assist and Communiport – which integrates the car’s audio, computing, navigation and wireless communication through hands-free voice activation. Additionally, the interior of the Cien features a digital instrument display relaying all of the vehicle’s functions, including diagnostics and satellite navigation, to the driver. LCD screens display images from the rearview cameras. A state-of-the-art entertainment system designed to match the car’s unique acoustic characteristics is incorporated into the cockpit.

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.
