Pontiac G8 GXP officially rated at 415 hp

The V8-powered Pontiac G8 GT has garnered a fair amount of respect around Autoblog HQ, with almost everyone who's spent time behind the wheel singing the praises of the Aussie-imported four-door muscle car. We're all suckers for rubber-melting torque and rear-wheel motivation, and even El Capitan Neff has thought about retiring his Alero for a shot at G8 ownership. For the rest of us, a six-speed manual would seal the deal.

Next year Pontiac will finally offer a proper cog swapper on its G8 GXP, and not only do drivers get to row their own gears, but they're getting an extra 13 horses and 15 lb.-ft. of torque to boot. The SAE has finally performed its official testing on the 6.2-liter LS3 V8 and output is up to 415 horsepower and an equal amount of twist.

With 19-inch HSV wheels framing 14-inch (front) and 12.76-inch (rear) discs and Brembo calipers, a standard LSD and a stiffened suspension, the additional power is just another reason to be smitten by the Pontiac G8 GXP. That, and the Tremac TR060 manual.
