Cadillac CTS-V Sedan

The CTS-V Sport Sedan quickly established itself among the world’s highest performing luxury sedans, becoming the first production four-door on street tires to break the legendary eight-minute barrier at Germany’s famed Nürburgring.

It is powered by a supercharged 6.2L V-8 that delivers 556 horsepower (415 kW) and is 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.

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.

The CTS-V rolls into 2012 virtually unchanged, offering only a trio of new exterior colors – Black Diamond Tricoat, Opulent Blue Metallic and Mocha Steel Metallic (late availability on Mocha Steel Metallic) – to complement its well-established performance credentials. Rainsense automatic windshield wipers are added, too.

The CTS-V Sedan exterior incorporates a number of unique cues that blend function with aesthetics. The dihedral Cadillac grille, for example, is larger to enable more air intake and features a satin finish, while the raised hood encompasses the supercharged engine beneath it. The front and rear fascias, as well as a rear spoiler that houses the center high-mounted stop lamp, are specific to the car, as are its standard 19-inch wheels.

The CTS-V Sedan interior features streamlined instrumentation, LED lighting and hand-cut-and-sewn accents. It includes performance seats featuring perforated sueded microfiber inserts designed to hold the driver and front passenger in place during cornering. Recaro performance driving seats are optional and provide excellent support during performance driving. These 14-way adjustable performance seats include pneumatic bolster controls in the seat cushions and backrests.

Complementing the performance seating are a thick steering wheel and a gauge package designed for easy, at-a-glance reference during performance driving. Large instruments have bold readouts, including an LED-lit “tracer” function in the tachometer that flashes as the engine nears the red line. The gauge layout includes a boost gauge and a lateral acceleration display.

Obsidian Black accents grace the center stack, console, steering wheel and door panels. The production steering wheel and shifter are available in Alcantara, providing the luxurious character of suede.

The CTS-V Sedan’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 Sedan – 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.”
