We knew the new super-spec 2009 Cadillac CTS-V would be getting some impressive output numbers, and today the official figures are out — 556 HP at 6,100 RPM and 551 lb-ft of torque at 3,800 RPM. With those bitchin' numbers, the CTS-V will be doing 0-60 MPH in a lightning fast 3.9 seconds, with a standing quarter mile coming in at 12 seconds flat. Sure, but how fast will she go? What about 175 MPH with the six-speed auto and 191 MPH with the manual transmission? Okay, we're a little light-headed at the moment; obviously the CTS-V is warping the space around our brains.
