Cadillac CTS-V Coupe

The Cadillac CTS-V Coupe is the most dramatic model in the V-Series range of high-performance luxury models, blending a personal 2+2 layout with a drivetrain vetted on Germany’s famed Nürburgring.

A supercharged 6.2L V-8 is the power behind the CTS-V Coupe, delivering 556 horsepower (415 kW) backed by either a six-speed manual transmission or a six-speed automatic. A collection of technical and performance elements complement the powertrain, including Magnetic Ride Control, Brembo brakes and Michelin Pilot Sport PS2 performance tires mounted on 19-inch forged aluminum wheels, as well as a track-proven brake system with two-piece front rotors. They offer greater resistance to warping and potentially longer rotor life, as well as reduced weight.

A unique grille that doubles front-end airflow to help enable its high-performance capabilities is one of the V-Series’ distinguishing features, along with an aggressive front fascia and raised center section of the aluminum hood that provides clearance for the supercharger.

Continuous improvements have helped keep the CTS family at the top of customer consideration lists and earned it critical praise. That tradition continues in 2014, as the CTS-V Coupe offers four new exterior color choices – Phantom Gray Metallic, Mocha Steel Metallic, Majestic Plum Metallic (available at an extra cost) and Red Obsession Tintcoat (available at an extra cost) – and a new Sport Blue interior package.

The CTS-V’s 6.2L supercharged V-8 engine is rated at 556 horsepower (415 kW) and 551 lb.-ft. of torque (747 Nm). It is the most powerful engine in Cadillac’s history.

The engine features an intercooled Eaton Twin Vortices Series™ (TVS™) supercharger, which employs twin four-lobe rotors that are twisted 160 degrees. Typical superchargers feature three lobes twisted 60 degrees. The fourth lobe and greater helix profile, when combined with unique air inlet and outlet ports, create smoother, more efficient airflow into the engine. In addition to improved overall efficiency, this supercharger has superior noise and vibration characteristics compared to more ordinary designs.

A pair of six-speed transmissions is offered in the CTS-V Coupe – a Tremec TR6060 six-speed manual with a dual-disc clutch and a Hydra-Matic 6L90 six-speed automatic with steering wheel-mounted shift controls. The steering wheel-mounted controls require no shift lever movement and allow immediate tap up/tap down gear selection. Performance Algorithm Shifting provides the automotive transmission with a performance-oriented shift pattern during sustained high-performance driving. As with many Cadillac models, the driver needs only to slide the shifter into the manual “gate” to put the transmission into a performance mode.

Torque is channeled through the six-speed transmissions to a high-performance rear axle that features a limited-slip rear differential within a cast iron housing for greater thermal management, and asymmetrical half-shafts to smoothly manage the supercharged engine’s incredible torque. The unique design includes alternately sized half-shafts that also help dynamically balance the oscillation of torque from side to side, effectively eliminating “power hop.”
