Cadillac Celebrates "Cien" with V-12 concept
Cadillac's two-seat, 750-hp 7.5-liter V12 mid-engine luxury sports car is one of three General Motors’ concept vehicles set to be unveiled at the Detroit auto show in January. The others are a Saturn 2+2 roadster named Sky and a GMC five-person truck, Terra4. The Cadillac, dubbed Cien (Spanish for 100 in honor of the marque’s centennial next year), is built around a carbon fiber monocoque and an all-new, aluminum Northstar XV12 (the X for concept) developed in conjunction with Cosworth Engineering. The transmission is a semi-automatic gearbox with F1-style paddle shifters.
General Motors’ premium Cien mid-engined sports car concept, powered by a 750-hp, 7.5 liter V12, was designed to help usher in the brand's 100th anniversary next year. The Cien will be shown at the Detroit auto show in January.
The Cien (Cien is Spanish for 100) illustrates Cadillac's 'art and science' philosophy, melding design and technology in a mid-engine, two-seat sports car.
"With the Cien, we've created the ultimate expression of 'art and science' using dynamic lines to achieve geometric forms similar to those of the Evoq, Imaj and Vizón concept vehicles that preceded it," said lead designer Simon Cox, executive director of GM's Advanced Design Studio for Cadillac in Birmingham, England.
Cien's low, sleek appearance, introduces a different proportion for Cadillac. Trapezoidal air inlets are milled into the front-end surface graphically forming Cadillac's shield-like grille along with the centrally mounted badge. The bank of air inlets cools the front-mounted radiators, and is flanked on either side by vertical headlamps.
In profile, Cadillac's crisp-edged spline that runs the length of the bodyside from front to rear suggests tension in the surface. Another taut line answers the first -- sweeping over the rear wheel well to return to front.
The body and chassis are made of carbon fiber composite. Cien is equipped with scissor-style doors that pivot at the base of the A-pillars upon opening.
Functional side air intake and exhaust vents lay flush with the surface of the car, opening up as required. Formal, directional sail panels, which appear to float above the surface, house air intakes for the V-12.
Cien's rear view recalls Cadillac's design heritage with fin-like, vertical taillights, full-width center high mounted stop lamp (CHMSL) spanning the deck and a centerline crease. Cien also features an adjustable rear spoiler and a removable hardtop roof.
Nestled between the engine and the 19-inch front and 21-inch rear wheels is a computer-influenced driver's cockpit featuring Cadillac's leading-edge telematics, including 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.
Night Vision uses thermal imaging to help a driver detect potentially dangerous situations well beyond the range of the car's headlamps. The image is relayed to the driver via a head-up display.
Cien is equipped with LCD panel screens to display information from the car's navigation system and rearview cameras. The high-tech interior features a digital instrumentation and an analog clock. A state-of-the-art entertainment system was designed to match the car's unique acoustic characteristics and incorporates headrest speakers.
Interior aluminum accents and prominent vertical elements reinforce the vertical graphic theme of the exterior. Rich, inviting materials, contrast the cool technical appearance, balancing contemporary feel with touches of modern luxury. Further, the interior complements the concept's lightweight theme, utilizing carbon fiber and aluminum structural elements in a design that combines luxury and performance.
Cadillac Cien's 7.5-liter, V-12 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, double overhead cam (DOHC) four-valve V-12 engine generates 750 horsepower and 450 lb.-ft. of torque, yet it meets the packaging requirements and fuel economy standards of a V-8.
The Northstar XV12 concept engine features several technological advancements over today's V-8 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 for quicker, quieter starts.
