Cadillac Cien Concept

In 2005 it was released the Cadillac Cien Concept. The 2 seats car presented a new and innovative design and had a V12 powerful engine of 7.5 liters. Dubbing the Northstar XV12, the Cadillac Cien Concept has a rear window coming from GM Powertrain. The engine of this car is an 4 valves V12 double overhead cam (DOHC) engine that provides 750 HP and 450 lb of maximum torque. Despite this, the car meets the standards of a V8 engine regarding fuel economy and CO2 emissions. To maximize this fuel savings, the engine is set to run seamlessly on 6 cylinders. Also, the gasoline combustion from the direct injection helps in increasing the obtained power and reducing the CO2 emissions. There are also quicker starts, thanks to the combined starter generator. This engine is paired with directional sail panels, exhaust vents and air intake on the side.

The new Cadillac Cien is a two-seat car with a new design and a technology in a mid-engine. The new model is powered with a V-12 engine and is the technology flagship for General Motors.

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

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. 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.

The body and chassis are made of carbon fiber composite that is lightweight and stiff. Cien is equipped with scissor-style doors that pivot at the base of the A-pillars upon opening.
