Cadillac CTS Coupe Concept, 2008

Cadillac CTS Coupe Concept, 2008

The Cadillac CTS Coupe takes Cadillac's acclaimed Art and Science design language and adds more of both. More expressive, more technical and very personal, the Cadillac CTS Coupe extends the dramatic design of its sedan predecessor with all-new sculpted bodywork aft of the front fenders.

The Cadillac CTS Coupe Concept has a classic 2+2 interior layout, highlighted by black leather and Alcantara microfiber trim that is complemented by yellow ochre-colored seat inserts and leather stitching. It is designed to accommodate a range of engines for the global luxury market, including Cadillac's popular 3.6L Direct Injection V-6, as well as a new 2.9L turbo-diesel currently in development.

Generated from the spark of the CTS design team's imagination, the Cadillac CTS Coupe casts a profile unlike anything else on the road. Its fast-rake styling - it has the same wheelbase as the CTS, but an overall height that is approximately four inches (101 mm) shorter - blends with hand-sculpted bodywork that bulges around the wheels, giving the vehicle a ready-to-pounce stance that is dramatic, powerful and sleek.
A design gem
Among the Cadillac CTS Coupe Concept's signature design cues are a number of elements that suggest the look of a carefully cut diamond - particularly at the rear. These elements are seen in everything from the chrome header above the rear license plate holder to the indents that comprise the basic form of the rear fascia.

• Based on the sedan, the Cadillac CTS Coupe shares only the instrument panel, console, headlamps, front fenders and grille with the production model. Unique elements:
• Classic hardtop styling, with no B-pillar
• CTS production windshield laid at a faster angle to create a sleeker profile
• Chrome, split seven-spoke wheel design; 20-inch front wheels and 21-inch rear wheels
• Sculpted lower front fascia with unique brake-cooling vents
• Slim-profile outside mirrors
• XLR-type hidden door handles with proximity remote opening
• Unique front fender vents
• Diamond-cut rear fascia with mesh lower grilles and center-outlet exhaust
• Taillamps with a subtle fin profile and are highlighted with LED lighting technology with light pipes
• Rear spoiler integrated into the center high-mounted stop lamp
• Sculpted roof-mounted antenna for OnStar, XM Satellite Radio, etc.

The surfaces of Cadillac CTS Coupe Concept are complex, inviting careful inspection. The rear fenders, for example, were sculpted by hand in the design studio until they provided a perfect, muscular form that wrapped tightly over the wheels. At the top, the rear fenders are beveled - owing to the diamond-cut theme - and become part of a horizontal plane that runs from the leading edge of the tail lamps and merges into the roof.

Personal passenger environment
A classic 2+2 interior environment enhances the Cadillac CTS Coupe's personal feel. It shares the hand cut-and-sewn instrument panel and center console with the CTS, but features unique front and rear seats, a continuous console running between the front and rear seats, and custom door panels.

Black microfiber fabric covers the front armrest, as well as an armrest located between the rear seats. The armrests are part of a continuous console that stretches from the instrument panel to rear seats. Carbon-fiber trim accents the console. The interior also features ambient lighting throughout, creating a distinctive environment at night.

Performance-bred powertrain and suspension systems
As is the case with its design, the Cadillac CTS Coupe extends the acclaimed capabilities of the sedan in terms of performance technology. This includes the capability to support a broad engine range of gasoline and diesel engines.

The Cadillac CTS Coupe, of course, ascertains the sedan's 3.6L V-6 engines, including the 304-horsepower (227 kW) Direct Injection power plant. The Coupe Concept also is designed for a new 2.9L turbo-diesel being developed for international markets. This new engine, tailored for use in the CTS, will deliver an estimated 250 horsepower (184 kW) and 406 lb.-ft. of torque (550 Nm).

A 6-speed manual transmission backs the engine, sending torque to an independently sprung rear axle. The CTS Coupe's sport-tuned suspension gives it a slightly lower ride height than a production CTS - a look enhanced by the car's rakish shape and large, 20-inch front and 21-inch rear wheels.

Cadillac CTS, 2008

Cadillac CTS, 2008

Aggressive and elegant, expressive and sophisticated, the 2008 Cadillac CTS exudes a dramatic design presence. This all-new luxury sedan not only pushes Cadillac's acclaimed design theme higher, it aims to redraw the boundaries of the normally conservative luxury sedan category. Inside and out, the 2008 CTS contradicts many traditional design conventions. CTS' design expresses its serious performance intent, yet also is more elegant and luxurious. It's a sedan in the heart of the luxury market, yet reaches for the charisma of a sports car. CTS is thoroughly new and contemporary, even while it evokes the grandeur of classic Cadillac cars.

Since the inception of the first-generation car in 2002, CTS is about trend-setting design. The edgy form of the CTS initially created controversy. But from the moment it hit the market, its design also attracted lots of buyers, with design often noted as a top reason for purchase. The all-new 2008 edition extends that edgy and contemporary character, with an injection of elegance.

On the exterior, there's no mistaking the five-passenger sedan's stronger stance, thanks to a two-inch wider track. Additionally, the overall shape of the CTS features a faster profile with more rake, coupled with surfaces that add elegance and grace. Borrowing from Cadillac's legendary heritage, design cues include vertically shaped headlights and taillamps, signature light emitting diode (LED) exterior lighting, horizontal spline lines and its dihedral-shaped hood, all highlighted with many bright and jeweled accents.

Exterior: sporty sophistication meets substance
Coupled with a new overall shape, the most evolutionary dimension of the 2008 CTS comes in the form of a two-inch wider track as a result of the addition of the new, optional all-wheel-drive configuration. The wider stance gives the new model a more planted, capable and well-grounded appearance that's exemplified by much tighter tire-to-fender relationships.

The wider stance also enables more tumblehome - the vehicle sides are sculpted inward - delivering an appearance of rear-wheel-drive performance with a lower roof line, without compromising headroom or a roomy interior.

Seven-spoke, 17-inch wheels or available nine-spoke, 18-inch wheels surround larger high-performance brake calipers and rotors. Both painted and machined finishes are available for the standard 17-inch wheels. The larger, 18-inch wheels are available in a premium multicoat finish or a high-polish finish.

Inspired by Cadillac's landmark Sixteen concept car, the CTS front appearance is immediately recognizable, yet also is new. The large, chrome dual-textured grille is significantly more vertical in shape, and is both aggressive and intricate. A large center-positioned wreath and crest add to the three-dimensional face. The front fascia is balanced with vertically stacked headlamps with bright bezels stacked in a staircase-like array. The lower air intake is flanked on both sides with fog lamps and brake duct intakes.

Side air extractors located forward of the front doors are a modern homage to Cadillac's grand heritage. Additional bright details include chrome molding surrounding the side windows, and three-inch chromed exhaust outlets.

Dimensionally, the 2008 CTS is 191.6 inches (4766 mm) long, 72.5 inches (1841 mm) wide and 58 inches (1472 mm) in height. Wheelbase is 113.4 inches (2880 mm) with a front/rear track of 61.8 / 62.0 inches (1575 / 1585 mm).

Interior: performance and elegance combine
The 2008 CTS represents a new design theme for Cadillac interiors, emphasizing technical precision with elegant, hand-crafted details. Dramatically different from the original, the interior design is decidedly more upscale, with added ornamentation, luxury and attention to detail. Strict attention to packaging, premium materials, surface development and comfort combine to meet the discriminating tastes of luxury performance sedan buyers.

New 3.6L V-6 VVT, six-speed automatic join powertrain lineup
The 2008 Cadillac CTS features GM's new 3.6L direct-injection V-6 VVT engine, delivering an estimated 300 horsepower (223 kW) and 270 lb.-ft. (366 Nm) of torque. This new powerplant is a compelling mixture of power, smoothness, efficiency and technical sophistication.

The 3.6L direct-injection engine will be the top-level engine option for the 2008 CTS, joining the existing 2.8L V-6 and 3.6L V-6. Designed to operate with regular unleaded gasoline, the new 3.6-liter direct-injection V-6 produces power similar to many V-8 engines, but with much better fuel economy. With direct injection, fuel is delivered directly to the combustion chamber to create a more complete burn of the air/fuel mixture. Less fuel is required to produce the equivalent horsepower, especially at normal cruising speeds, of a conventional port-injection combustion system.

Chassis enhancements include all wheel drive, globally tested suspension
The 2008 CTS features a greatly revised chassis featuring a two-inch wider track and the application of all-wheel drive. The front track is increased to 61.8 inches (1569 mm), and rear track is now 62.0 inches (1575 mm). Wheelbase remains at 113.4 inches (2880 mm).

Cadillac engineers have designed and developed new geometry for both the independent short/long arm front suspension and the multilink rear suspension. Engineers implemented numerous tweaks and revisions to the suspension using extensive computer modeling, combined with development driving of prototype cars on roads all over the world, but mostly in North America, Europe and China .
