General Motors has been the perpetrator of several fortunate and unfortunate badge engineering jobs over the years, and the G8 -- based off the Holden Commodore -- is the most recent example. The Aussie sedan was partially developed with American sales in mind and because of that, it doesn't take much to give your spiffy new G8 a nose job inspired by the Land Down Under. Australian firm JHP Vehicle Enhancements will sell you an entire body kit to change your G8 into a Holden for a mere, um, $4,000 if you choose to go all out in an attempt to replicate the HSV model. That's a sizable chunk of change, but beauty is in the eye of the beholder. Since we're less concerned with appearances, we'd just put the extra scratch towards upgrading to the GXP.

We couldn't help but listen to the comments of other onlookers as we closely inspected the G8 GXP Street Concept in the G8 booth. Every reaction was overwhelmingly positive, from the overall design to the motor. After all, what's not to like? For starters, the standard 6.2L V8 has been replaced with an LSX454 crate motor that uses the LSX Bowtie block, six-bolt LSX cylinder heads and a forged rotating assembly. In total, the 7.4L V8 pushes out a massive 638 horsepower and 600 lb-ft torque that's directed through a 6-speed automatic transmission. The exterior gets a makeover with new front and rear fascias, rocker panels, custom upper and lower grilles and black chrome trim. Inside, the G8 GXP Street Concept also gets custom leather trimmed seats, a new gauge cluster and more black chrome. Yeah, it's basically a four-door ZR1. You can look at all the details of the car in the gallery of live high-res photos below.

One of the best parts about SEMA is getting to see the manufacturers build cars they might not otherwise. Take this G8 GXP Street Concept, for example. Sure, the 415-horsepower 6.2L V8 in the standard G8 GXP is plenty good enough, but why not stuff the new LSX454 crate engine from GM Performance Parts underneath the hood? The 7.4L V8 is good for a ZR1-matching 638 horsepower and 600 lb-ft torque, allowing this G8 to unashamedly call itself a true muscle car. Other features include stiffer springs and the brake package from the CTS-V as well as 20-inch black chrome wheels. The exterior has been given an aggressive makeover with a new front fascia with unique upper and lower grilles and a rear fascia that incorporates a diffuser and performance exhaust system. Inside are custom leather seats and a new gauge cluster. More details and plenty of photos are soon to come when we hit the show floor next week. Thanks for the tip, Jonathon!

Pontiac hopes to clear things up with a post on Pontiac blog regarding the future of its current products, namely the G8 and Solstice. It was just the other day that rumors of the brand's two rear-wheel drive vehicles possible being canceled hit the interwebs, and we dutifully reported on the story as we always do. According to Pontiac, though, those rumors are nothing more than speculation and should not be taken as gospel unless you hear it from the horse's (or Mr. Lutz's) mouth, which we have not. Still, the rumor in question indicates that the G8 will live on at least another five years, assuming it continues to sell that long, but would not be replaced after that. This could still be the case. Likewise, the Solstice has not been canceled, but it's replacement in GM's lineup still seems unlikely given the low volume of sales the vehicle attracts. In short, nobody can predict the future, but sometimes the handwriting on the wall isn't that tough to read.

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. We'll take ours in slate grey for maximum intimidation. Thanks for the tip, Torrent!

Although we thoroughly enjoyed the fleeting time we spent with the Pontiac G8 GT, what whith its 361 horsepower and 385 pound-feet of torque and all, it's the upcoming GXP model that truly looks to catapult the Australian-bred sedan back into musclecar territory. We, along with just about every other gearhead, are especially looking forward to the six-speed stick and clutch pedal with which the 6.2-liter LS3 V8 making 402 hp and 400 lb-ft of torque will be paired. Of course, the rest of the car needs to be up to snuff too, so we are happy to take a gander at these spy photos of a pre-production prototype in Australia that indicate the nineteen-inch GXP-specific wheels and big Brembo disc brakes are present and accounted for. A slightly revised front fascia with a lower splitter combine with the rear diffuser to further signify that this is the high-zoot version of Pontiac's sport sedan.

Coupes seem to be somewhat resurgent lately, and the stupendously awesome Pontiac G8 GXP might be set to lose a pair of doors. While that would make it essentially a repeat of what came here as a revived GTO not too long ago, the name is not likely to return. The basic idea has been outlined in the Holden Coupe 60, itself starting out as an updated GTO, but turning out much cooler. The neo-ponycar wars will require the fitment of the 400 horsepower LS3 to run with the Shelby GT500KR, Challenger, and cousin Camaro.

The newly unveiled G8 GXP serves as the benchmark for what this coupe will likely come equipped with. That means big 19-inch wheels, uprated suspension, a meaner fascia and, most importantly, an available Tremec six-speed manual transmission. There should be a GT version, too, with "only" 361 horsepower, which should still offer a significant kick in the pants for less cash. The biggest impediment to the G8 Coupe actually seeing the light of day are looming new CAFE regulations, but we don't see how selling a bulk of these cars with the still-excellent 3.6 liter V6 to less performance-addled customers would be a bad thing. It'd hopefully prevent Pontiac from running afoul of the fuel economy rules while getting another car out there that enthusiasts can embrace in a variety of flavors. Thanks for the tip, Matthew!

It's a rare occurrence when honest applause breaks out in a press conference over a new model, let alone a transmission. But that's exactly what happened when Maximum Bob talked up the Pontiac G8 GXP, and specifically its optional six-speed manual transmission. Mated to that highly coveted cog swapper is the 6.2-liter LS3 V8 pulled from the Corvette, making 402 hp and 400 lb.-ft. of torque. If you opt for the 6L80 auto 'box, you can check your manhood and an extra two lb.-ft. of torque at the door.

In addition to the upgraded engine and manual tranny, the GXP benefits from the 19-inchers originally shown on the G8 concept, Brembo brakes (sized 14-inches up front and 12.76 inches out back) and some revised suspension bits. Zero-to-60 times are down to 4.7 seconds and the G8 GXP (along with the Solstice coupe and 'ute) are all due to hit dealers later this year.

Pontiac's full press release is posted after the jump, and our own live high-res shots can be seen in the gallery below (we're going to be adding more as soon as the pandemonium surrounding the vehicle dies down.

The upcoming 2008 Pontiac G8 has a lot going for it. There's the oh-so-hot-right-now rear-wheel-drive chassis, a base price under $28,000 and the high-performance G8 GT with a 361-horsepower 6.0L V8 starts below $30,000. It's the performance bargain of the year, and if a forum post over at G8GT.com is to believed, the bargain is about get a whole lot better.

A dealership employee somewhere has posted a pic of GM's inventory controls website in which the engine option for the 2009 Pontiac G8 GXP is revealed to be none other than the LS3 6.2L V8. To refresh your memory, the LS3 replaced the LS2 as the base engine for the Corvette this model year. In the Vette, it produces 430 horsepower from 376 cubic inches, or 436 hp if you opt for a special dual-stage exhaust system.

There was a time when the Corvette kept all of its components to itself, but that ended when they started building the Cadillac XLR side-by-side with the iconic American sports car and began using its engines in the CTS-V. Nowadays, Cadillac regularly pilfers the Corvette parts bin, so why not Pontiac, too? An LS3-powered G8 GXP would be just short of epic in its degree of awesomeness, so let's hope the internet is right on this one. Thanks for the tip, John!
