The numbers are in, and it looks like the all-new 2009 Cadillac CTS-V has set the bar for the fastest V8-powered sedan ever produced. 556 horsepower. 551 lbs.-ft of torque. And 0-60 mph in 3.9 seconds.

Cadillac just announced the official performance specifications for the 2009 CTS-V:

• Supercharged 6.2-liter LSA engine, has achieved SAE-certified peak output of 556 hp (415 kW) at 6100 rpm and 551 lbs.-ft. (747Nm) 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 V8-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 the addition of 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.



In testing on May 8 at Germany’s famed Nürburgring, the all-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.
