2007 Cadillac CTS-V
The landmark V-Series is a core part of Cadillac’s historic renaissance, providing a group of powerful cars able to seriously compete with the world’s best and attract new consumers to the brand’s revitalized product range. V-Series is about expressing Cadillac performance and luxury to the fullest extent.
The V-Series also has adopted a “handcrafted” approach featuring hand-cut, sewn and wrapped interiors and custom-built engines, bringing a new level of attention to detail, accuracy and craftsmanship to the vehicles, as well as more elegant executions.
The charter member of the V-Series vehicles, the CTS-V is an emphatic statement of Cadillac’s entry into top-level competition with the world’s finest luxury sports cars.
The four-door, rear-wheel drive CTS-V uses the overhead valve 6.0L V-8 LS2 engine with 400 horsepower (298 kW) and 395 lb.-ft. (536 Nm) of torque. It achieves 0-60 mph in less than 5 seconds with a top speed of 163 mph (262 km), and the quarter mile 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 camshaft opens the valves faster and higher, enabling more airflow in and out of the combustion chambers and contributing to horsepower gains
- High-strength pistons help improve engine durability, particularly under high-performance operating conditions
- Revised valves and stiffer valve springs better accommodate valve operation with the high-lift cam
- Enhanced induction system enables enhanced engine breathing, helping to increase horsepower output
- High-flow intake manifold delivers high amounts of airflow to the intake ports, helping to ensure a broad torque curve while delivering maximum power
- High-flow fuel injectors deliver fuel at the faster rate needed due to increased intake airflow
- Dual exhaust constructed 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 cover helps reduce underhood noise and features the Cadillac wreath and crest in its center and V-Series identification over each cylinder bank
CTS-V chassis refinements include revised front engine cradle to handle the high horsepower and torque from the V-8 engine. The front stabilizer bar was increased from a 23-mm hollow bar to 26.6-mm hollow bar. Spring rates also were increased from 55 to 70 – a 27-percent increase.
Shock diameter was increased from 36 to 46 mm and valving refined to suit the vehicle’s high-performance driving characteristics. For weekend racers and performance enthusiasts, a “Nürburgring” shock package featuring firmer dampers is available through General Motors Service Parts Organization.
A new steering gear also is included for more precise steering tuning.
A Brembo brake system with 355 x 32 mm front and 365mm x 28 mm rear rotors is incorporated in the CTS-V. The vented rotors are complemented by four-piston front and rear calipers, and linings are tuned for reduced noise and outstanding braking performance.
Tires are Goodyear 245/45WR18 EMT (run flats) mounted on 18 x 8.5-inch aluminum alloy, six-lug rims. Underneath, a belly pan is positioned under the most forward portion of the vehicle to reduce aero drag and lift at high speeds.
Exterior enhancements on the CTS-V are 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.
