We thought Bentley's announcement earlier today that it's adding a Speed model to the Continental Flying Spur lineup was exciting news for sedan fans. After all, a 600bhp saloon that can hit 60 mph in 4.5 seconds and reach 200 MPH is pretty exciting, no? Not really when compared to Cadillac's news that the 2009 CTS-V will officially be rated at 556 horsepower, hit 60 mph in 3.5 seconds and run the quarter mile in 12 seconds flat. No offense to Bentley, but a sub-3-second sedan is about as exciting as it can get on a Monday. 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 engine is the LSA, 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 destroy its German competition, specifically the BMW M5 with its - can't believe we're saying this - relatively meager 500-hp 5.0L V10

PRESS RELEASE

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).
