Officially Official: 2009 Cadillac CTS-V Makes 556 Horsepower Plus Full Gallery

Introducing the new Cadillac 2009 CTS-V, officially rated at 556 horsepower. It will hit 60 mph in 3.5 seconds and run the quarter mile in 12 seconds flat. For the record, the Edmunds’ Straightline Blog reports that the sport sedan’s 6.2L supercharged V8 will produce 556 hp at 6,100 rpm and 551 pound-feet of torque at 3,800 rpm. That kind of power is courtesy of the LSA engine, derived from the new Corvette ZR1’s LS9 motor and detuned for duty in the CTS-V. Fortunately, the LSA wasn’t detuned too much and the ‘09 CTS-V should be darn good competition for its German competition, specifically with BMW’s M5 relatively meager 500-hp 5.0L V10.

2009 CTS-V Performance Reaches The Stratosphere

Certified at 556 horsepower, acceleration times are top among V-8 sedans

MILFORD, Mich. – As final testing of the limited-edition 2009 CTS-V nears completion, the results suggest that Cadillac’s upcoming sports sedan is entering the stratosphere of the world’s highest-performing cars. Cadillac announces the following performance specifications for all-new 2009 CTS-V:

CTS-V, with its supercharged 6.2-liter LSA engine, has achieved SAE-certified peak output of 556 horsepower (415 kW) at 6100 rpm and 551 lb.-ft. (747 Nm) of torque at 3800 rpm.
CTS-V accelerates from 0-60 mph in 3.9 seconds. CTS-V covers the quarter-mile in 12 seconds at 118 mph. These acceleration times are believed to be the fastest for any V-8-powered sedan currently in production.
More than just power, CTS-V also includes a comprehensive suite of technical and design enhancements, including Magnetic Ride Control and a new automatic transmission with paddle-shift control. Cadillac pioneered Magnetic Ride Control, the world’s fastest-acting suspension, in 2004. The new CTS-V employs a new version of this technology, enabling it to achieve a remarkably wide bandwidth of capability that ranges from extreme high-performance agility to the smooth road manners of a prestigious luxury sedan.

CTS-V also manages power via an extremely robust driveline. The car’s limited-slip differential is made of cast iron for extreme strength. Its limited-slip tuning enables excellent high-speed stability along with comfortable low-speed maneuverability. The prop shaft is heavy-duty and wheel hub bearings are stiffened and bolstered to manage the car’s remarkable energy. Axle half-shafts are asymmetrical, a design that ensures smooth performance.

“CTS-V represents the full extension of our design, technology and performance capabilities,” said 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.”

In testing May 8 at Germany’s famed Nürburgring track, the new 2009 CTS-V completed a lap of the legendary Nordschleife in 7:59.32. This blistering time appears to be the fastest ever publicly documented for a production sedan on factory-spec street tires.

One of the realistic objectives of the Cadillac team is to make the CTS-V the world’s fastest production sedan, as a part of the overall goal to make the V-Series Cadillac’s ultimate expression of performance and technology. A video of the car’s breakthrough Nürburgring performance is online in many locations, including Cadillac’s home on the Internet (Cadillac.com/09ctsv), and at the blog documenting Cadillac performance development (http://Cadillac.gmblogs.com).
