CADILLAC CTS-V DELIVERS PERFORMANCE, POWER, HANDLING AND STYLING

The CTS-Vprovides high-performance driving enthusiasts with a serious, credible alternative to imports in the highly competitive, low-volume luxury performance segment, including the BMW M-Series, Mercedes-Benz AMG Series and Audi S-Series.

"V" stands for performance

The V-Series has been designed to take Cadillac's performance credentials to an entirely new level. With 400 horsepower (298 kw), CTS-V is the most powerful production model Cadillac has ever offered.

Based on Cadillac’s performance-oriented rear-drive Sigma architecture, CTS-V is a highly refined high-performance luxury sedan designed for performance enthusiast drivers.

Like the original CTS, CTS-V was refined and validated at Germany's famed Nurburgring racetrack to meet the expectations of the world's most avid driving enthusiasts.

For 2005, two new exterior colors, Red Line (extra charge) and Stealth Gray will debut, along with a Light Gray interior (available midyear).

Functional air dam and brake ducts

Serious performance credentials
The four-door, rear-wheel-drive CTS-V has the overhead valve 5.7L V-8 LS6 engine producing 400 horsepower (298 kw) and 395 lb.-ft. (533 Nm) of torque. It makes 0-60 mph in 4.6 seconds and has a top speed of 163 mph (262 km).

Engine highlights include an aluminum block, two-valve cylinder heads with revisions to the air induction system, and an enlarged dual exhaust system for an impressive V-8 sound. The LS6 V-8 provides CTS-V with racetrack-proven performance, along with smooth, quiet operation and outstanding reliability, durability and quality. The engine’s lightweight aluminum construction – including its cylinder heads and block – delivers an excellent power-to-weight ratio (1:9.6) and good chassis balance (54 percent front / 46 percent rear).

Power is delivered through the six-speed manual Tremec T56 transmission that features a dual mass flywheel for reduced noise and vibration harshness. A heavy-duty, increased diameter, 70-mm prop shaft is used for the higher torque requirements. The limited-slip rear axle is fitted with a 3.73:1 final drive ratio to optimize acceleration.

Performance modifications
To help develop and manage its higher horsepower and torque output, and to reduce noise, vibration and harshness, the CTS-V received several performance modifications including:

High-profile camshaftopens the valves faster and higher, enabling more air to flow into and out of the combustion chambers and contributing to horsepower gains
High-strength pistonshelp increase engine durability, particularly under high-performance operating conditions
Revised valves and stiffer valve springsbetter accommodate valve operation with the high-lift cam, hollow intake valves reduce mass and permit extremely high cam lift, and the sodium-filled exhaust valves help ensure proper cooling
Enhanced induction systemenables enhanced engine breathing, helping to increase horsepower output
High-flow intake manifolddelivers high amounts of airflow to the intake ports, helping to ensure a broad torque curve while delivering maximum power
High-flow fuel injectorsdeliver fuel at the faster rate needed due to increased intake airflow
Reconfigured exhaust manifoldspermit increased exhaust flow while maintaining low levels of noise
Dual exhaustconstructed of 2.5-inch (159-mm) diameter stainless steel pipe to help minimize back pressure, increase horsepower and ensure proper exhaust tone. Investment-cast stainless steel tips cap the exhaust pipes
Engine coverhelps reduce underhood noise and ties directly to the exterior performance styling of the vehicle with the Cadillac wreath and crest in its center and V-Series identification positioned over each cylinder bank

Following extensive development at the Nurburgring, the racing-inspired Brembo 14-inch (355-mm) front and 14.4-inch (365-mm) rear disc brakes provide remarkable deceleration and reduced braking distances with aluminum four-piston calipers on all four corners. Included on the caliper casting is distinctive V-Series identification. Specific seven-spoke 18-inch by 8.5-inch aluminum, six-lug wheels and Goodyear P245/45WR18 EMT (run flat) tires are standard.

Performance-tuned suspension
To handle the high-output horsepower and torque, CTS-V is equipped with an extremely robust front and rear suspension. Specific refinements include:

Hydroformed front/rear cradleshandle the greater mass of the LS6 engine (front) and 180 lb.-ft. (244 Nm) increase in torque surging through the driveline (rear) as well as enhancing NVH performance
Larger stabilizer bars decrease body roll by increasing roll stiffness
Increased front/rear spring ratesenhance performance-oriented handling characteristics
Larger monotube front shocksincrease damping capacity and provide better thermal performance
Nivomat rear shocksautomatically adapt spring and damping rates to changing load conditions for enhanced handling and ride performance
Performance-tuned elastomeric ride bushingsfitted to aluminum control arms to bring precise on-center feel, enhance linear performance under high-speed braking and reduce control arm movement at high speeds

The StabiliTrak stability enhancement system assists the vehicle in maintaining the driver’s intended path by applying a brake force at any corner of the vehicle independent of the driver’s use of the brake pedal. It is standard equipment and includes four driver-selected modes of operation, including a competition mode for better track performance. The extensive chassis tuning carries over from the 2004 model, including larger shock absorbers and 26.6-mm front and 21-mm rear stabilizer bars. Front and rear spring rates are increased by 27 percent from the CTS.

Purposeful design
On the exterior, the CTS-V includes enhancements designed to increase performance, including a unique front fascia with an integrated aero splitter for better aerodynamics and brake ducts vented to cool front brakes. Stainless steel mesh grilles, both below and above the bumper, offer a unique front appearance and allow for free air flow into the engine compartment. Sides include a unique aero rocker design that flows into a specific rear fascia.

Underneath the hood, a tower-to-tower cross-car brace has been installed for improved steering response and linearity under high-performance conditions. To help reduce underhood noise, a unique nylon cover, which features the Cadillac wreath and crest and V-Series logo, is fitted over the top of the engine.

A full dual exhaust system exits through the rear fascia and is capped with chrome oval exhaust tips. The "V" logo appears on the deck lid and front fenders and also on brake calipers, rocker panel and the speedometer in the instrument cluster.

Interior geared toward performance driving
CTS-V offers a unique instrument cluster trimmed with satin chrome rings around each gauge. Aircraft-style, white lettering on a black field is used on gauges for better legibility. The instrument cluster also includes two driver information centers (DIC) located in the instrument panel. The left DIC can display performance-oriented information including peak and momentary lateral acceleration, oil, transmission and coolant temperatures, and oil and tire pressure. The right DIC indicates odometer, digital speedometer and reverse gear and skip-shift indicators.

The sleek interior of the CTS-V

Other interior design features include a three-spoke steering wheel with an aluminum bezel and specific controls for CTS-V. Satin chrome finishes also are used on the shift knob, door pulls and door handles. The center armrest has been lowered significantly for easier shifting during driving. Driver and passenger seats include adjustable lumbar and sueded fabric insert material to help maintain driver position in lateral maneuvers.

All engineering work for the CTS-V was performed by the GM Performance Division, an in-house center designed to explore potential enthusiast-oriented versions of production models. CTS-V will be produced at GM's Lansing Grand River assembly center, the award-winning manufacturing site for the CTS, SRX luxury utility and STS luxury sedan.
