If the Cadillac STS-V wasn't powerful enough for your tastes at only 440 HP, you're in luck. Under the new SAE J2723 standard, the supercharged 4.4 L Northstar will be certified to produce 469 HP at 6,400 RPM and 439 lb-ft of torque at 3,900 RPM. If that horsepower rating sounds a bit familiar, it's because it just so happens to be what the supercharged AMG V8 has been rated at for the past few years. Doing a bit of simple math, we can deduce that the Northstar is still making 389 lb-ft at the horsepower peak, meaning that those fortunate enough to own such a vehicle are going to enjoy a very wide powerband. The XLR-V unfortunately won't be making quite as much power due to more restrictive underhood packaging, with 443 HP and 414 lb-ft of torque. Both of those figures occur at the same RPM as the STS-V application. While you're at it, go hit GM test driver John Heinricy's entry over at the Fastlane blog, download the video of him whipping around the STS-V, and bemoan the fact that your job probably isn't as fun as his.
