Cadillac CTS-V chassis refinements include revised front engine cradle to handle the high horsepower and torque from the V-8 engine. The front stabilizer bar was increased from a 23-mm hollow bar to 26.6-mm hollow bar. Spring rates also were increased from 55 to 70 - a 27-percent increase.

Shock diameter was increased from 36 to 46 mm and valving refined to suit the vehicle's high-performance driving characteristics. For weekend racers and performance enthusiasts, a "Nurburgring" shock package featuring firmer dampers is available through General Motors Service Parts Organization.

A new steering gear also is included for more precise steering tuning.

A Brembo brake system with 355 x 32 mm front and 365mm x 28 mm rear rotors is incorporated in 2007 Cadillac CTS-V. The vented rotors are complemented by four-piston front and rear calipers, and linings are tuned for reduced noise and outstanding braking performance.

Tires are Goodyear 245/45WR18 EMT (run flats) mounted on 18 x 8.5-inch aluminum alloy, six-lug rims.

Underneath, a belly pan is positioned under the most forward portion of the vehicle to reduce aero drag and lift at high speeds.

Exterior enhancements on the CTS-V are designed to increase performance, including a unique front fascia with an integrated aero splitter for better aerodynamics and brake ducts vented to cool front brakes. Stainless steel mesh grilles, both below and above the bumper, offer a unique front appearance and allow for free air flow into the engine compartment. Sides include a unique aero rocker design that flows into a specific rear fascia.

Cadillac CTS-V offers a unique instrument cluster trimmed with satin chrome rings around each gauge. Aircraft-style, white lettering on a black field is used on gauges for better legibility. Other interior design features include a three-spoke steering wheel with an aluminum bezel and specific controls for Cadillac CTS-V. Satin chrome finishes also are used on the shift knob, door pulls and door handles. The center armrest has been lowered significantly for easier shifting during driving.

Cadillac CTS-V is produced at GM's Lansing Grand River assembly center, the award-winning manufacturing site for Cadillac CTS, Cadillac SRX luxury utility and Cadillac STS luxury sedan.

* SAE certified: A voluntary power and torque certification procedure developed by the SAE Engine Test Code Committee was approved March 31. The procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing to the SAE J1349 standard. GM was the first auto manufacturer to begin using this procedure and expects to use it for all newly rated engines in the future.
