The first V-Series vehicle, the CTS-V provides 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.
For 2006, CTS-V receives a new engine, and the power sunroof will now be standard equipment.
The four-door, rear-wheel drive CTS-V now uses the overhead valve 6.0L V-8 LS2 engine (replacing the LS6) producing the same 400 horsepower (298 kw) and 395 lb.-ft. (536 Nm) of torque. Acceleration figures include 0-60 mph in 4.6 seconds with a top speed of 163 mph (262 km). The quarter mile is achieved in 13.1 seconds at 109 mph.
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 LS2 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 (53 percent front / 47 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.
To help develop and manage its higher horsepower and torque output, and to reduce noise, vibration and harshness, the CTS-V features several modifications, including:
-High-profile camshaftopens the valves faster and higher, enabling more airflow in and out of the combustion chambers and contributing to horsepower gains
-High-strength pistonshelp improve engine durability, particularly under high-performance operating conditions
-Revised valves and stiffer valve springsbetter accommodate valve operation with the high-lift cam
-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
-Dual exhaustconstructed of 2.5-inch (159-mm) diameter stainless steel pipe to help minimize back pressure, increase horsepower and ensure proper exhaust tone. Polished stainless steel tips cap the exhaust pipes
-Engine coverhelps reduce underhood noise and features the Cadillac wreath and crest in its center and V-Series identification over each cylinder bank
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.
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. 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.
CTS-V is produced at GM's Lansing Grand River assembly center, the award-winning manufacturing site for the CTS, SRX luxury utility and STS luxury sedan.
