The engine features an intercooled Eaton Twin Vortice
s 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.”
CTS-
V
Coupe driving experience
The
V
-Series is designed for great road-holding performance, while maintaining the
poise of a luxury car in average driving conditions. This is enabled by
Cadillac’s
landmark Magnetic Ride Control,
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
Coupe 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.
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.
Additional chassis and suspension features include:
