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!

It looks like things will be getting a lot less exciting at Pontiac, as some reports indicate that the erstwhile performance brand will be losing its best performers. Despite the fact that the G8 sedan has seen nothing but positive press from the media, including your humble scribes here at Autoblog, the realities of fuel economy and the global economy appear set to kill off the rear-wheel drive performance sedan in the prime of its short life. GM will reportedly not renew the G8 after its Holden-sourced chassis architecture is redesigned following a planned five-year run.

The Pontiac Solstice in both coupe and convertible forms is also unlikely to see a second generation. Unfortunately, the Solstice, Saturn Sky and their Opel spin-off don't generate enough sales to support another go-round, which could leave Pontiac with exactly zero vehicles with overtly sporting pretensions. While the G6 may be a decent car, it and a Cobalt derivative in the form of the G5 and a rebadged Aveo known as the G3 do not a BMW competitor make. What does this mean for the future of Pontiac as a brand? We'll see.

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.

The Northeast is the Pontiac division's largest market, and the brand -- which has played the stepchild in recent years, banished to the outer limits of exhibition halls -- is finally getting its own coming out party in New York next week. The resurgent Performance Division will flex its muscles at the Javits Center. Joining the 2010 G8 sport truck (and maybe another newcomer sporting the Arrowhead badge) is the highly-anticipated Pontiac G8 GXP.

The new Poncho flagship wears subtle visual tweaks including updated front and rear fascias plus the same 19" HSV wheels that were shown on the G8 concept. More importantly, the GXP packs GM's 6.2L LS3 V8 underhood. In this application (it's also in the Vette, where it makes even more power), the small-block punches out 402 horses and 400 lb-ft of torque rearward via a Tremec 6-speed manual gearbox or a HydraMatic 6L80 auto. (Add another 2 pound-feet of twist if you opt for the latter.) A fully-adjustable suspension helps keep the muscle sedan planted to the tarmac, and stopping power comes from the gang at Brembo. Look for an upgraded interior with glitzier trim and well-bolstered leather sport seats. A Pontiac stand littered with V8s? It's sure been a while. Welcome back to the party, guys. Let the wanton tire destruction begin!

We'll have plenty of live shots for you from the floor on Wednesday.

GM loves to tease its American customers. While we patiently await the arrival of the Pontiac G8 GT, in Australia, multiple high-performance flavors of the VE Commodore its based on are available from HSV. In the UK, one of those cars, the HSV Clubsport R8, is offered as the Vauxhall VXR8.

With 412 horsepower (417 PS) and 405 lb-ft of torque on tap, one would think that the rebadged HSV would be sufficiently awesome for our former colonial overlords. One would also be incorrect. Carscoop reports the Brits will be offered a supercharger option that elevates power to a staggering 540 horses and adds 30-percent more torque (figure a new rating of 526 lb-ft or so). The non-supercharged VXR8 does 0-60 in 4.9 seconds, so you can expect the blown sedan to shave a few more tenths off that number while making expensive tires cry for their mothers. The cost of the kit is £6,995.

Please, General: Pontiac G8 GXP Supercharged, okay?
