Much like our beloved Holden does just about every year down here in Australia, Pontiac will take the opportunity presented by SEMA to unveil a seriously slick street-worthy show special - the G8 GXP Street Concept (although Holden usually keeps its specials secret until the day of the unveiling).
Aesthetically, the GXP Street Concept bears a number of modifications â€“ some subtle, some aggressive, but all very striking. Massive 20-inch black rims reminiscent of those found on 70s muscle cars sit under the guards of the Holden-designed body. What appear to be red â€˜haloâ€™ LED rings surround the main driving projectors.
The grille opening has been significantly narrowed top to bottom, looking a lot more like its VE Commodore cousin as a result. To top it all off, a massive, wide-open air dam is bedecked with a pair of blacked-out fog lights on either side of a serious looking strip of mesh.
This is all fantastic of course, but the real meat of the story lies beneath. While the regular G8 GXP carries the world-destroying 310kW 6.2-litre V8 LS3 seen in HSVâ€™s 2008 range, the Street Concept is packing the new 7.4-litre LSX454 crate engine from GP Performance Parts. Weâ€™re talking 855kW and 810Nm of torque, just so weâ€™re clear.
Backing all that up is a stiffer suspension setup, and the Cadillac CTS-Vâ€™s brakes â€“ though who knows if even theyâ€™ll be enough.
Stay tuned for more information and images as the G8 GXP Street Concept is unveiled at SEMA.
