So it seems as if the tightly held embargo on Cadillac’s monster CTS-V has been totally obliterated, with multiple online outlet trumpeting the racy sedan loud and clear.

And why wouldn’t they be excited? The CTS-V looks to be a shockingly high-performance vehicle, with a V-8 derived from the motor powering everyone’s favorite super-Corvette the ZR1, and looks that make even the toughest M5 look downright bland.

Cadillac may be phasing out the V-8 from its run-of-the mill sedans, but it's not going anywhere for the foreseeable future in the V-series. The 6.2-liter engine makes a gratuitous 550 horsepower along with a matching 550 pound-feet of torque. That level of power will launch a lucky driver from 0-60 mph in less than five seconds, a figure that we’re still trying to wrap our heads around from a Caddy.

Another gift to the new CTS-V from the ZR1 is the optional six-speed Tremec 6060 dual plate clutch, a device hearty enough to handle the massive force of torque produced by the car’s motor.

Visually the most stunning feature of the Cadillac seems to be the massively creased power bulge topping the car’s hood, a feature necessitated by the space needed for a cross-brace over the huge engine. The 2009 CTS-V also continues the first generation car’s tradition of donning a cool mesh grill, as well as wearing a sick set of 19-inch, 10-spoke wheels.

2009 CTS-V: CADILLAC'S ULTIMATE EXPRESSION OF PERFORMANCE AND LUXURY

DETROIT - As the new CTS sport sedan earns accolades and new owners, Cadillac takes the next leap forward by premiering the 2009 CTS-V, the brand's ultimate expression of performance and luxury.

Launching in the fourth quarter of 2008, the all-new CTS-V intends to combine the serious performance of an elite sports car with the poise and elegance of a prestigious luxury sedan. Part of Cadillac's acclaimed V-Series of high-performance models, CTS-V delivers an estimated 550 horsepower (410 kW). More than just power, CTS-V also includes a comprehensive suite of technical and design enhancements, including Magnetic Ride Control, an industry-first Performance Traction Management program and the addition of a new automatic transmission with paddle-shift control.

"The CTS-V represents the full extension of our design, technology and performance capabilities," says Jim Taylor, Cadillac general manager. "The V-Series takes the award-winning CTS sport sedan and elevates it to a position within the club of the world's most exclusive and capable cars."

As an all-new version of the CTS sport sedan was prepared for 2008, Cadillac engineers and designers began to scheme a new CTS-V that would reach much higher in terms of performance and luxury. Through the original CTS-V, Cadillac proved it could develop a very potent, high-performance sedan. The challenge for the 2009 model was enhancing every aspect in a comprehensive manner, along with reaching higher performance limits.

Several key technical and design elements combine to transform the already highly capable CTS into the new V-Series. Like the existing CTS, the V-Series is the product of an intensive development process across North America and Europe, including famed test tracks and millions of miles of road. Supporting Cadillac's ongoing global expansion, the 2009 CTS-V is planned to be offered outside North America for the first time, including exports to Europe, the Middle East and Asia.

Sophisticated technical enhancements
The 2009 Cadillac CTS-V features the world's fastest-reacting suspension technology, Magnetic Ride Control (MRC). It uses shocks controlled by electro-magnets, rather than mechanical valves, greatly accelerating response time. 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. This is of particular benefit for a high-performance sedan, helping to keep the car very composed during hard cornering, acceleration, braking and other dynamic maneuvers.

MRC technology first appeared on the Cadillac STS performance sedan and has been used on some of the world's most celebrated cars, including the Chevrolet Corvette and a select few European sports cars.

Enabling the precise control expected in a high-performance sedan, the CTS-V features Performance Traction Management system, borrowed from championship racing teams. This technology uses advanced electronics to manage engine torque for optimal traction during acceleration. In situations such as acceleration from a stop or exiting corners, Performance Traction Management regulates torque delivery for the best possible launch.

Performance Traction Management uses the same sort of electronics as stability control programs such as Cadillac's StabiliTrak system, but applies it in a different manner. Rather than monitoring and controlling wheel slip to assist in stopping or slowing the car, PTM regulates torque delivery to instantly match the available tire grip for maximum acceleration.

CTS-V also includes sophisticated braking and tire systems, in partnership with two companies renown 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. Michelin worked with Cadillac engineers to develop its acclaimed Pilot Sport 2 (PS2) summer tire for CTS-V and its 19-inch wheels.

And, of course, there is the matter of power. It has increased nearly 35 percent for the '09 CTS-V, via a new 6.2L LSA supercharged V-8 engine generating an estimated 550 hp (410 kW) and 550 lb.-ft. (745 Nm) of torque. The engine delivers this power with remarkable refinement. A sixth-generation Eaton supercharger minimizes the added noise previously associated with supercharged engines, and tightly controls intake air temperature for optimal performance.

Transmission choices include either a six-speed manual or an exclusive, six-speed automatic with steering-wheel-mounted paddle shifters. It is the first automatic offered on the CTS-V.

Accentuated design elements
The 2009 CTS-V extends Cadillac's acclaimed design language, both inside and out. The V-Series includes all the elements of the CTS sport sedan's well received cabin, while adding some elegant and purposeful accents.

V-Series will offer Recaro performance driving seats, providing excellent support for spirited driving and adding to the luxurious and purposeful interior. These new, 14-way adjustable performance seats include pneumatic bolster controls in the seat cushion and backrest.

A microfiber material is added to the steering wheel, seats and shifter, providing the soft feel and luxurious appearance of suede without suede's inherent drawbacks of difficult care and moisture sensitivity. These accents on the steering wheel, seat inserts and shifter are elegant to the touch and help support high-performance driving.

The car's integrated center stack is trimmed with a new Obsidian material that is also applied to the center console and door trim. Just like every CTS, the V-Series includes a hand-stitched instrument panel, door trim and center console. Leading-edge infotainment features, including a 40-gigabyte hard drive, advanced navigation system with a "pop-up" screen and Bose digital surround audio, extend to the V-Series, as well as factory-installed Bluetooth capability.

The exterior of the new CTS-V amplifies the assertive stance and elegant details of the standard car, and communicates the car's remarkable capabilities. The dihedral Cadillac grille is larger to enable more air intake and features a satin finish. The raised hood encompasses the supercharged engine, and new front and rear fascias identify the vehicle as a V-Series. The car's 19-inch wheels enhance its stance on the road.

The founding member of the V-Series, CTS-V was initially offered in 2004 and sold primarily in North America through the 2007 model year. The supercharged STS-V and XLR-V were added in 2006 to make the V-Series an exclusive trio of models all capable of zero-to-60 acceleration in less than five seconds with enhanced overall performance and luxury features.
