Press Release) ALL-NEW 2008 CADILLAC CTS DESIGN INTENDS TO
INJECT DRAMATIC CHARACTER INTO THE LUXURY SEDAN CATEGORY
DETROIT – 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.
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
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.
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.
The all-new 2008
Cadillac CTS has been painstakingly designed and engineered to unite
luxury sedan poise and sports car performance. A redesigned chassis,
an enhanced engine and transmission lineup and all-wheel drive
combine to push the CTS further in all directions with more power
and performance, enhanced ride quality, quietness and safety.
The first-generation CTS (2002-2007) helped re-establish Cadillac’s
rear-wheel-drive performance credentials. The landmark CTS-V, a
400-horsepower specimen of power and precision, ushered in a new era
of performance for both its drivers and the engineers who created
it. With this in mind, the Cadillac team behind the 2008 CTS took to
development roads in Germany, China and the U.S. intending to
enhance the car’s power and performance in every way. The result is
a machine capable of serious performance driving, while
simultaneously delivering the panache unique to luxury sedans.
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
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
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
The engine cradle has six attachment points, two more than typically
used on a performance sedan, to better handle heavier loads and
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.
In addition to this finely tuned hardware, 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.
