A trio of potent Pontiacs is hitting SEMA next week, led by the G8 GXP Street concept with a monster crate engine.
This sedan gets a 7.4-liter powerplant that pumps out 638 hp and 600 lb-ft of torque and is paired with a six-speed automatic transmission. Ride height is lowered, and it gets stiffer springs, disc brakes stolen from the Cadillac CTS-V and custom 20-inch aluminum wheels with a black chrome finish.
The exterior gets custom fascia front and rear, unique upper and lower grilles and more black chrome.
The G8 ST concept is based on the truck version of the G8 that’s due in late 2009. It’s lowered, gets 20-inch wheels, a custom interior trim kit and a hard tonneau cover. Power comes the 6.0-liter small block V8 that makes 361 hp and is paired with a six-speed automatic.
The Solstice GXP Coupe concept is a nifty fastback with a removable roof panel for fresh-air fans. It gets a performance air-intake and General Motors’ Stage 2 performance kit, which boosts output to 290 ponies. It also gets cat-back exhaust and a race-ready suspension kit.
