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.

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.

A wider, tapering sail panel, lower, more sculpted hood, smoother wheel housing lips and a tighter wheel-to-body relationship help communicate the CTS' agility as well as its sophistication and substance.

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.

Upper instrument panel and door trim surfaces are hand-cut, sewn and wrapped by expert craftsmen. Analog instrumentation that is tightly framed with a compact hood tri-tubular, chromed cluster, is defined by bright accents. An integrated center stack design, with either a satin metallic finish or genuine Sapele wood, blends into the lower instrument panel that sweeps forward and away of front-seat occupants. The hand-assembled center console leads seamlessly into the center stack, providing a sportier "cockpit" feel for the driver and passenger without compromising space.

The leather-wrapped steering wheel includes standard integrated controls for cruise and audio system.
Inside and out, the 2008 CTS exemplifies an evolution of Cadillac design that achieves a remarkable combination of luxury, technology and performance in a sedan aimed at creating the desire and head-turning quotient normally reserved for sports cars.

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.

The application of gasoline direct-injection technology on the 3.6L VVT engine contributes greatly to a 15-percent increase in horsepower; 8-percent increase in torque, and 3-percent improvement in brake-specific fuel consumption. Additionally, the application of direct injection reduces cold-start hydrocarbon emissions by 25 percent.

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 . From famed tracks such as Germany 's Nürburgring to everyday roads in the U.S. and China, the CTS suspension was exhaustively tested and honed.

The use of aluminum in the upper and lower front control arms and knuckles helps reduce mass and contributes to higher limits in handling and dynamic wheel control. Front suspensions for the rear-drive model and the all-wheel-drive version, while similar, have been designed to best meet the chassis dynamics of the individual versions.

The engine cradle has six attachment points, two more than typically used on a performance sedan, to better handle heavier loads and engine vibration.

New for CTS is a tower-to-tower brace that adds cross-car stiffness and enhances the overall steering feel. This is an innovation from the high-performance CTS-V model that has been modified and adapted for use in the 2008 CTS.

The multilink rear suspension, with a fully isolated subframe, is an uncompromising design with excellent suspension kinematics that delivers a superior ride with excellent handling. The rear suspension design is shared in both the rear-wheel and all-wheel-drive models, and has been extensively revised to accommodate the larger rear track.

The braking and steering systems for CTS are all-new, with extensive changes to increase responsiveness, premium "feel" and performance in spirited driving conditions.

The 2008 CTS features standard 17-by-8-inch aluminum wheels paired with Michelin H-rated (P235/55R17) all-season radials. The optional performance suspension includes an 18- by- 8.5-inch wheel with the all-new Michelin Pilot Sport 2 (P235/50R18) tire that can either be V- or Y- (summer) rated.

Cadillac Converj Concept

With the Cadillac Converj Concept General Motors unveiled a further glimpse at the potential of electric propulsion, this time in the form of luxury transportation. The Cadillac Converj was developed as a well-appointed grand touring coupe with a bold design and a host of interactive technology.

The four-passenger Cadillac Converj concept is intended to show how GM's revolutionary electric propulsion technology - called Voltec - can power a luxury coupe with a typically Cadillac "no compromises" design. The technology enables up to 40 miles of gas- and emissions-free electric driving with extended-range capability of hundreds of miles.

Bob Lutz, GM's vice chairman of Global Product Development, said the Cadillac Converj concept has production substance. "It's a logical extension of our plan to reinvent the automobile," he said. "It clearly shows what a Cadillac electric vehicle could look like, and clearly indicates that global luxury customers can have a car that has both strong design and electric propulsion with a total range of hundreds of anxiety-free miles."

Cadillac's extended-range electric vehicle (E-REV) concept has a new body style that is an evolution of the brand's traditional Art and Science design theme. An aggressive, forward-leaning arc profile is the foundation for the sporting stance. And more than a Cadillac in form, Converj is also intended to be a Cadillac in substance, with the premium materials, technology and driving dynamics that are hallmarks of the brand.

Voltec - innovative propulsion technology

The Cadillac Converj's Voltec electric propulsion system is made up of a 16-kWh, T-shaped battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car.

A thermally managed battery pack contains more than 220 lithium-ion cells that provide the primary power to drive the Cadillac Converj electrically up to 40 miles without using fuel or producing tailpipe emissions. The battery is integrated into the Cadillac Converj's chassis and stores electricity from the grid when the vehicle is plugged in. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet.

When the battery's energy is low, the Cadillac Converj seamlessly switches to extended-range mode. During this secondary level of operation, electricity needed to power the vehicle is created on-board by a flex-fuel-powered engine that operates much like a home generator to create electricity. The engine-generator ensures a constant supply of power for hundreds of miles until the car is refueled or plugged in to recharge the battery. This extended-range mode eliminates the range anxiety that comes with driving pure electric vehicles that offer no backup power when the battery charge is low.

Whether in electric or extended-range mode, the Cadillac Converj is propelled all the time by an electric drive unit. It converts electrical energy from the battery or the engine-generator into mechanical energy to drive the front wheels. It also delivers 273 lb.-ft. (370 Nm) of instant torque, for a quick launch, and 120 kW of power. The top speed is 100 mph.

There is no compromise in vehicle performance in either mode of operation. To enhance the ride feel, the Cadillac Converj Concept also features GM's Magnetic Ride Control; and for even greater efficiency, energy during braking is captured and stored in the battery.

Pure Cadillac design

There's no mistaking the Converj for anything but a Cadillac, according to Lutz. "An aggressive, forward-leaning profile hints at a new, progressive theme and proportion in Cadillac's design evolution," he says. "The new proportion showcases a uniquely shaped, modern vision of a personal luxury 2+2."

The overall shape is reinforced by a prominent, sweeping body line with large, 21-inch (front) and 22-inch (rear) wheels pushed to the edges of the body. The Cadillac Converj exterior is painted a dark silver tri-coat that GM designers dubbed "Reaction."

An all-glass roof incorporates solar panels that help offset power drain from the vehicle's accessories. Additionally, several aerodynamic and design efficiencies were incorporated to enhance the driving range, including:

* A full under-vehicle cover (belly pan)
* Minimal grille openings that reduce drag at the front of the vehicle
* Low-profile rearview cameras replace conventional outside mirrors to reduce drag
* Wheels are shaped to push air outward for smoother body side airflow

The Cadillac Converj also incorporates vertical headlamp and taillamp elements, with light pipe technology.

"Vertical lamps are Cadillac signatures and the Cadillac Converj builds on the brand's light pipe technology with bolder light emitting diode (LED) and high-intensity discharge elements front and rear," said Clay Dean, global design director for Cadillac. "There is also a unique daylight light 'spear' at the top of the headlamps."

Luxury meets technology inside

The Cadillac Converj's interior has advanced features and luxurious appointments blending efficiency and environmental consciousness. The 2+2 configuration is trimmed in contrasting Winter White synthetic suede - including the top of the instrument panel - and Midnight Black leather, with polished aluminum and wood grain accents. Renewable materials are used throughout such as wool-blend carpeting, a headliner made from silk, suede made from post-industrial content and more.

A technologically advanced driver center increases efficiency and reduces the draw on the battery. Features include:

* New, organic light-emitting diode technology used on reconfigurable instrument cluster
* Touch-screen navigation, climate, center-stack controls and audio systems
* Adjustable, overhead white ambient lighting
* Unique "power on" sequence featuring blue-lit console graphics
* Screen displays for features including regenerative braking, battery charge level and power output
* No inside rearview or outside mirrors; cameras provide surrounding images on a screen placed high on the instrument panel for a full, panoramic view
* Push-button ignition and power-folding front seats
