A few weeks back, GM's resident speed demon engineer John Heinricy took a production spec CTS-V to an all-time lap record of 7:59.32 for a production sedan at the Nürburgring, and this week Cadillac revealed the official SAE certified power numbers for the super-Caddie at 556 horsepower and 551 pound-feet of torque.

When we got to Milford our handlers took us out to a tent by the Lutz-ring test track where we found three CTS-Vs and various displays of the hardware contained within. Heinricy was on hand as well to tell the tale of the "fast lap" last month. For those who may not have been paying sufficient attention over the past 6 months, the CTS-V is GM's answer to all those German uber-sedans like the Mercedes E63 AMG, Audi RS4 and RS6 and, of course, the one that started the madness, the BMW M5. Read on after the jump to learn more about what makes this Caddie so special and what it was like to go for a ride.
