CTS-V Sport Sedan details
The CTS-V Sport Sedan has 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 suite 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. It rides on 19-inch forged aluminum wheels available in silver painted or polished finishes.

Supercharged performance

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

The engine features an intercooled Eaton Twin Vortices Series™ (TVS™) supercharger. This unique supercharger design employs twin four-lobe rotors, twisted 160 degrees. Typical superchargers feature three lobes twisted 60 degrees. The fourth lobe and added twist, 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 Sport Wagon – 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.”

Magnetic Ride Control, Brembo brakes and Michelin PS2 tires

The V-Series achieves exceptional levels of road-holding performance, but also maintains the poise of a luxury car in “regular” driving conditions. The technical enabler of this dual-mode driving character is Cadillac’s landmark Magnetic Ride Control. It is the world’s fastest-reacting suspension technology. It uses shocks controlled by advanced magneto-rheological technology, rather than mechanical valves, to greatly accelerate response time and precision. Electronic sensors at all four wheels literally “read the road” every millisecond, making constant adjustments to damping to create virtually instantaneous and extremely precise control of body motions.

The Magnetic Ride shocks also enable a broader range of damping control to optimize the ride and handling for all driving conditions. In the CTS-V, an extra measure of control is offered, with two selectable modes (Tour and Sport), enabling the driver to tailor the suspension for grand touring or more spirited performance driving.

The CTS-V also incorporates sophisticated braking and tire systems, in partnership with two companies renowned for high-performance technology: Brembo and Michelin. Brembo brakes are at all four corners and include powerful, six-piston calipers in the front and four-piston calipers in the rear.

Large, vented rotors enable strong initial braking force while optimizing heat resistance and eliminating fade. The brake rotors from Brembo are manufactured with “dual-cast” technology that combines cast iron and aluminum, resulting in superior performance and weight reduction.

Michelin partnered with Cadillac engineers to develop an exclusive Pilot Sport PS2 tire specifically engineered for the CTS-V. The tires support high levels of grip in track conditions, while also affording excellent performance on the road.

Comfort, style and technology

The interior of the CTS-V 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 for spirited 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. These accents are elegant to the touch and aid the driver during high-performance driving.
