G6 GXP Street edition models are easily identified by their new front fascia, which features new fog lamps and braided polished stainless steel upper and outboard lower grille inserts with chrome surrounds on the upper grille sections leading to a revised hood with scoops. New body side rocker moldings lead to a redesigned rear fascia with two exhaust openings. Chrome, dual-wall tips exit through the openings. A rear spoiler also is part of the GXP package, but is specific to either the coupe or sedan; the coupe model receives a larger, more aggressive “hammerhead” spoiler. GXP-specific 18-inch wheels are also standard in the Street edition package.
