Not much has been heard about Pontiac’s new Solstice Coupe since it was unveiled back in March at the New York Auto Show, but the car is set to make headlines again, this time at the upcoming SEMA Auto Show. A new concept version of the Coupe fitted with an assortment of accessories from GM Performance Parts will be on show at the Las Vegas event, and if it proves popular the same specifications of the concept could be offered as a factory-backed performance package.

Like the Solstice Roadster, the new GXP Coupe is powered by a 260hp (194kW) 2.0L turbocharged Ecotec engine. The Coupe Concept, however, has been fitted with GM Performance Parts’ Stage 2 upgrade, which comes with a new intake kit that boosts power to around 290hp (216kW).

The concept also features a high-flow cat-back exhaust system and race-tune suspension riding on standard 18in alloy wheels. The exterior of the car has been finished in Olympic White trim with a Hydro Blue racing stripe. Inside, there’s more blue accents used on the leather stitching for the seats, as well as racing-style pedal covers, and an iPod interface for the stereo.

Pontiac will also showcase its Pontiac G8 GXP saloon fitted with a new 7.4L LSX454 V8 crate engine, which you can read about by clicking here.
