Cadillac CTS-V 2007
Cadillac V-Series: Cadillac Performance and Luxury Taken to the Fullest Extent
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.
Cadillac CTS-V 2007
The charter member of the V-Series vehicles, 2007 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 2007 Cadillac 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
