CADILLAC CTS Coupe (2011)

The Cadillac Aera Concept won the 2010 Los Angeles Auto Show Design Challenge, tying with Smart and besting entries from seven other automakers including Mercedes-Benz, Honda, Nissan, Toyota and Maybach. GM Advanced Design has now won the honor more times than any other design team; this is its third victory since 2005.

This is the seventh year for the contest, and this year designers were asked to envision the "1,000 lb. car" and tasked to imagine an efficient four-passenger vehicle that maintained comfort, safety, driving performance and style while not exceeding the weight requirement.

"The Cadillac Aera concept was designed to continue the forward-thinking imagination of Cadillac's 'art and science' philosophy," explains Jussi Timonen, lead designer for the project. "It's designed as a small city urban vehicle, but we approached this 2+2 touring coupe very much from the brand's luxury perspective. Every detail of the Aera was conceived to minimize the vehicle's environmental impact without sacrificing the style, comfort and attention to detail that are hallmarks of the Cadillac brand."

The Cadillac Aera Concept is powered by compressed air via a highly efficient Pneumatic Drive System that has a 10,000-psi composite air storage tank with capacity for a 1,000-mile range. Flexible, pressurized air cells in the exterior skin, similar to material developed for the NASA Mars Rover airbags, enhance passive safety and interior comfort. The flexible polymer skin optimizes aerodynamics and functions as an ultra-lightweight alternative to conventional body panels and glass.

Cadillac Aera's body utilizes a 3D lattice, mono-formed frame that was designed to be similar to configurations found consistently in nature. The structure is formed from unique, alloy-utilizing, semi-solid freeform manufacturing, creating a naturally strong, extremely lightweight frame. All major body parts, including interior components, are essentially "grown" into a single part lattice structure.

The interior is crafted with an ultra-light recyclable polymer that allows for HVAC channels, fully adjustable seating, storage and comfort features all in one mono-form structure. Generous storage space accommodates luggage for two people.

Additional technologies include an all-in-one wheel system that combines rotary actuator propulsion, steering and suspension functions. A drive-by-wire system decreases the mass of electrical components, while vehicle-to-vehicle communication promotes active safety.

The concept was conceived in GM's North Hollywood Advanced Design Studio by Frank Saucedo, director; Phil Tanioka, vehicle designer; Brent Wickham, concept strategist; Shawn Moghadam, layout designer and Timonen, the project manager. Earlier this week, GM commemorated 10 years of advanced design at the L.A. area studio.

"This year's design challenge was extremely difficult to judge because of the quality of all of the entries, but I believe that the executions that won exemplified everything that we were trying to achieve with this competition," said Stewart Reed, chair, Transportation Design, Art Center College of Design. "The concepts that won were really spot on for their brands, which was one of many reasons for the victory."

The Design Challenge is part of the Design Los Angeles automobile designers' conference and has evolved into an integral element of the Los Angeles Auto Show. Design Los Angeles connects those working in the design industry with well-known automotive design industry leaders. Los Angeles is home to the world's largest concentration of manufacturer design studios, representing automakers from North America, Europe and Asia. It is also the home of Art Center College of Design, one of the world's foremost transportation design institutions where many of today's leading automotive designers began their careers.

Cadillac CTS Sport Wagon, 2010

Amidst the beauty and history of the Pebble Beach Concours d'Elegance, Cadillac treats car enthusiasts to a world premiere of its latest production-car design. The 2010 Cadillac CTS Sport Wagon makes its debut on the Monterey Peninsula, showcasing a dramatic design that elevates and updates the classic wagon body style.

The new Cadillac CTS Sport Wagon is an unmistakable and dynamic presence. The car's intricately cut rear profile injects fashion-forward design into the formerly utilitarian world of wagons. Cadillac's upcoming wagon offers ample interior space and includes a range of six-cylinder engine choices, making it a compelling alternative to larger utility vehicles.

Based on the hot-selling Cadillac CTS sport sedan, and a sister vehicle to the Cadillac CTS Coupe Concept, the Sport Wagon extends the design-driven renaissance of Cadillac. Following this special premiere at Pebble Beach, the Cadillac CTS Sport Wagon moves to the worldwide auto show circuit this fall - and into Cadillac dealerships in spring 2009.

A striking profile is created with the Cadillac CTS wagon, with a silhouette that suggests speed and aerodynamic efficiency. It rides on the same 113.4-inch (2,880-mm) wheelbase as the Cadillac CTS sport sedan and is 0.3-inch (7 mm) shorter. However, it offers a generous cargo area of 25 cubic feet (720 liters) behind the rear seats.

Design highlights include:
* Signature V-shaped deck and tailgate motif
* Large, vertical taillamps with light-pipe technology
* Power-opening liftgate (via key fob or in-vehicle button)
* CHMSL integrated in subtle roof spoiler
* Integrated roof load management system with cross bars for a seamless appearance
* Cargo management system with adjustable in-floor containment
* New 19-inch wheels
* Larger available panoramic rear sunroof

The Cadillac CTS Sport Wagon, like its sedan predecessor, includes available features such as all-wheel drive, a 40-gigabyte internal hard drive, pop-up navigation screen and a hand-cut-and-sewn interior with Sapele wood accents.

Design details
Dramatic planes highlight the Cadillac CTS wagon's design, including a V-shaped motif carried throughout the vehicle and carefully integrated intersections of exterior surfaces. The elements coalesce in a dramatic fashion, creating tension that emphasizes the vehicle's performance.

The emotion of the Cadillac CTS Sport Wagon's design is carried by a number of nuanced details. The liftgate area, for example, is a confluence of angles and planes that typifies the vehicle's design tension. Cadillac's "V" motif is most prominent here, culminating in a spine at the center of the liftgate that is accented with a subtle spoiler at the top of the backlight. The rear quarter panels extend slightly beyond the inward-angled planes of the V, creating a distinctive W shape at the rear of the vehicle. Large, prominent vertical taillamps - with Cadillac's signature light pipe technology - are the final, dramatic touches to the rear-end styling.

One of the more interesting integrations of form and function is found in the seamless roof load management system. Rather than stylized stanchions, brackets and cross bars that protrude above the roof line, the Cadillac CTS Sport Wagon's system blends with the roofline, maintaining an uninterrupted appearance. The center section of the roof panel angles downward inside the roof edges, allowing an unobtrusive placement of the cross bars - and creating a subtle fin effect at the trailing edges of the rear panels.
The interior of the Sport Wagon is common with the much-acclaimed sport sedan, including streamlined instrumentation, LED lighting and hand-cut-and-sewn accents with French stitching.

Powertrains
Direct injection technology helps the Cadillac CTS offer more power while maintaining fuel economy and lowering emissions. It delivers fuel more precisely to increase the efficiency of combustion. This means less fuel is consumed and lower emissions created.

With the Cadillac CTS Sport Wagon's 3.6L V-6, direct injection translates to 304 horsepower (227 kW)*, no loss of fuel efficiency and a 25-percent drop in cold-start hydrocarbon emissions. It also runs on less expensive regular unleaded gasoline. The Sport Wagon's fuel economy is expected to be similar to the peak rating of the existing sport sedan's 26 mpg highway rating. The standard 3.6L VVT engine that produces 263 horsepower (196 kW) and 253 lb.-ft. of torque (343 Nm) serves as the base engine in North America.

Like the Cadillac CTS sport sedan, the V-6 engines are matched with fuel-saving six-speed transmissions, including an Aisin six-speed manual or an electronically controlled Hydra-Matic 6L50 six-speed automatic. As is the case on the sport sedan, Cadillac CTS Sport Wagon includes AWD as an option.

An efficient 2.9L turbo-diesel engine is being developed for Cadillac CTS models primarily in European and Asian markets. It is a compact, dual overhead cam, four-valve V-6 engine from GM's family of diesel engines that delivers optimal fuel economy as well as reduced emissions and noise. The engine is rated at 184 kW (250 hp).

Driving dynamics
The robust and dynamic CTS chassis infuses the new wagon with a great balance of performance and luxury. It uses an independent short/long arm ( SLA) front suspension system and a multi-link rear suspension.

The multi-link rear suspension features a fully isolated subframe that helps deliver excellent suspension kinematics, contributing to a superior ride and excellent handling.

Advanced chassis technology in the form of Cadillac's StabiliTrak electronic chassis control system integrates the car's standard four-channel ABS with the full-function traction control, hydraulic brake assist and engine drag control systems to deliver a safer, more confident driving experience. Additional chassis details include a structure-enhancing tower-to-tower brace under the hood; large, four-wheel disc brakes and premium steering.

Cadillac CTS Coupe Concept, 2008

Having earned critical acclaim, industry awards and brisk sales, Cadillac CTS has moved into the vanguard of contemporary design. In doing so, Cadillac designers faced the question of what to do next. Their answer celebrates that design legacy with the exhilarating Cadillac CTS Coupe Concept, which premiered at the 2008 North American International Auto Show.

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.

Though 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 include:
* 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 taillamps 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.

Custom-trimmed sport seats from Recaro are located in all four positions. They support the grand-touring nature of the car and are covered in rich, black and suede-like microfiber material, with yellow ochre-colored inserts. The yellow ochre color provides dramatic contrast with the black surrounding trim, but is a subdued hue consistent with the interior's overall feeling of refinement. Yellow ochre stitching also is used throughout, including the seats, instrument panel, shifter knob and more.

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.

Like the sedan, the CTS Coupe Concept's interior is home to a host of technologies, including a premium Bose audio system, 40-gigabyte hard drive and XM Satellite Radio. OnStar with Turn-by-Turn Navigation enhances the vehicle's onboard navigation system, which - like the CTS - features a screen that rises out of the center of the instrument panel.

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.

Behind the chrome, split-spoke, aluminum alloy wheels is a set of high-performance brakes, featuring cross-drilled rotors. Six-piston calipers clamp down on the front rotors, while four-piston calipers grab the rear rotors. All of the rotors have a distinctive, yellow-painted finish.

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.

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.

The 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.

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

Features:

* 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

Cadillac BLS Wagon 2008

Cadillac reinforced its commitment to grow its brand in Europe by announcing it will add the BLS Wagon to its portfolio later this year.

Cadillac signature style
Clear, clean, crisp and sharply defined contours are Cadillac design signatures. An international team of designers, under the leadership of Ed Welburn, GM vice president of Global Design, created a BLS Wagon with a striking wedge shape that is emphasized by the tapered lines of the side windows.

The fog lamps integrated into the body-colored bumper and a wide air intake below the grille. A narrow chrome strip runs along the side windows and the latest LED technology is used in the center high-mounted stop lamp, which is prominently positioned in the rear spoiler. Vertical taillamps, another Cadillac hallmark, play a prominent role in defining the elegant rear proportions of the BLS Wagon.

Luxurious, flexible interior and state-of-the-art infotainment systems
The BLS Wagon interior is highlighted by a three-spoke leather steering wheel and an analog clock in the center stack. The circular instruments have white numerals and red needles on a black background.

Flexibility and versatility define the rear seats and cargo area, which are designed to support a wide variety of luxury and leisure interests.

State-of-the-art infotainment systems include high-quality audio units from American sound specialist Bose, among others; a DVD navigation system with touch-screen operation; a Bluetooth-enabled cell phone system with a hands-free kit; and remote controls on the steering wheel.

Turbocharged diesel and turbocharged gasoline engines
The front-wheel-drive BLS Wagon is offered with a turbo-diesel and three turbocharged gasoline engines. The 1.9L four-cylinder diesel engine, with common-rail direct-injection technology, is fitted with a maintenance-free particulate filter and delivers 110 kW (150 hp) of power. The range of gasoline engines includes two 2.0L four-cylinder versions (129 kW / 175 hp and 154 kW / 210 hp), and a high-tech, 2.8L V-6 (188 kW / 255 hp) that features a twin-scroll turbocharger and variable phasing of the intake camshafts.

The BLS Wagon have six-speed manual transmissions and five- or six-speed automatic transmissions, depending on engine. For BLS models equipped with an automatic transmission, a standard Sport Mode button allows the driver to select a sportier transmission shift pattern.
Comfort and driving dynamics
The chassis, which features MacPherson struts in front and a four-link rear axle, is designed to provide the agility customers expect from a luxury wagon. The chassis tuning ensures dynamic handling performance without compromising comfort and load capacity.

Cadillac CTS, 2008

Aggressive and elegant, expressive and sophisticated, the 2008 Cadillac CTS exudes a dramatic design presence. The 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.

Just as definitive of CTS' evolution in design is the dramatically new interior. Like the exterior, it expresses luxury and performance themes with appointments that are both purposeful and elegant. Advances in surface development, technology, materials and construction combine to make the CTS cabin a compelling blend of technical sophistication, precise tailoring and luxurious character.

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.

Additionally, 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.

Even on the rear of the car, where many sedans are ordinary, Cadillac designers injected charisma. The vertical taillamps are a Cadillac trademark. The roofline and rear backlight have a coupe-like profile. At the centerline, the decklid carries the angular and directional theme of the front.

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.

Heated and ventilated seats incorporate new "thin-seat" technology for maximum occupant comfort and enhanced rear-seat leg, knee and foot room. A signature V-shaped medallion appears as a decorative touch on the backs of the front seats. French stitching is used throughout the interior, including the upper instrument panel, door inserts, seats and the shifter boot.

Clean, white ambient light emitting diode (LED) soft backlighting is positioned in the door pulls, foot wells and recessed between the upper and lower instrument panels. The result is a dramatic effect similar to recessed lighting used in contemporary homes.

The leather-wrapped steering wheel includes standard integrated controls for cruise and audio system.

The 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.

For the first time, the 2008 CTS will be available in both rear- and all-wheel-drive configurations. Additionally, the transmission lineup now consists only of six-speed units - an Aisin six-speed manual or - new for CTS - a Hydra-Matic 6L50 six-speed automatic.

The current 3.6L VVT engine that produces 258 horsepower (192 kW) and 252 lb.-ft (342 Nm) of torque will serve as the base engine in North America and will be available in rear- and all-wheel-drive layouts.

The 2.8L VVT engine will be available only on rear-drive export models of the CTS. The all-aluminum, 60-degree DOHC, four-valve-per-cylinder engine develops 210 horsepower (156 kW) at 6500 rpm and 194 lb.-ft. (263 Nm) of torque at 3200 rpm.

The Aisin six-speed manual transmission, introduced in 2005, is fully synchronized (including reverse) with a single overdrive. This allows for lower propshaft speeds and improved engine noise, vibration and harshness. A new short-throw shifter has been added for improved precision.

The Hydra-Matic 6L50 six-speed automatic is the same transmission introduced on the Cadillac STS-V in 2005, and is designed to decrease engine rpm and enhance overall fuel economy.

On vehicles equipped with the new all-wheel-drive system, the 6L50 will be equipped with a new active transfer case that automatically transfers torque from the rear to the front of the vehicle for optimal traction, safety and performance. A limited-slip differential also is available.

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.

The 2008 CTS features advanced chassis technology in the form of Cadillac's StabiliTrak electronic chassis control system. StabiliTrak integrates the car's standard four-channel ABS with the full-function traction control, hydraulic brake assist and engine drag control systems.
