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 Pontiacs version of the Holden HSV W427 except the Holden is a production car.

      I wouldn't kick it out of bed for eating cookies, but with some better wheels I'd be looking for a place to put a ring so I could spend my life with it. All the practicality of a family sedan, but with more fun under the hood than you can shake a stick at? Its like marrying a woman who can mother your kids, cook, clean, do laundry, get you beer, and do all the other stuff you get a wife for 'cus you don't like to do yourself, but she also happens to be an exceptionally skilled nymphomaniac who leaves you waking up every morning with that stupid grin still plastered on your face.

        couldn't have said better myself, some better wheels would be perfect!!
        • 6 Years Ago
        Well put :P

      That looks absolutely and positively like a BMW, especially the profile from the side. I'd say mostly like a 5-series.

        i love when people say that Pontiac looks like BMW!!!
        (the similarities end with two small grills in the front)

        the form language could not be more different.

      GM should save their money's to righting the big ship.
      • 6 Years Ago
      Wow, another huge power American Muscle sedan with (presumably, and if produced) a price tag way south of German rivals, impressive.

      And although I concede that turbos and SCs are more efficient, it is just so awesome to read those huge displacement numbers :)

      nlawless,

      GXP-R is a great idea. It wouldnt hurt for pontiac to create a G8 trim to run alongside the G6 GXP-R.

      The front end is plain ugly though. Just give it the front end of the regular GXP.

      The 7.4L V8 is a bit much if you ask me. The LS9 will do just fine.

      Droooooooooooooool!!
      • 6 Years Ago
      Yup, it's a hotter version of Australia's biggest selling car (Holden Commodore) with an uglier front slapped on
      • 6 Years Ago
      HOT

      Pretty much useless unless you live on a track. You don't need cars with that much power to be considered a performance division. People used to be happy with WS6s making what, 325hp? C'mon now. Seems these automakers just keep pricing themselves right out of business.
        • 6 Years Ago
        The same could be said for any performance cars.
        • 6 Years Ago
        It's a show car they built for SEMA, not a production car. Get over it.

        I guess you must have really hated the Camaro ZL-1 Chevy had back in 2000. It had a 572ci V-8 with 770hp. WHo would need that??

        Luckily for you, they never produced that car either, never had intention to as far as I know.

        Mostly, these projects are just done to play with the toys available from GM. Mixing and matching the parts and engines that can be bought from GMPP allows them to give some ideas to possible customers. SEMA is designed around the aftermarket business after all.

        GM is hardly alone in doing this, the Germans certainatly have done the same thing with their high performence cars.

        What would be better is if GM decided to export the Calais-V sportswagon from Holden rather than doing show cars but each to their own.

      I'm am really (NOT) digging that grille.
        • 6 Years Ago
        I think it's functional...looks very functional to me, and function>form.
        • 6 Years Ago
        The whole front end is hideous
        • 6 Years Ago
        Looks like a stainless steel gas grill I saw at Home Depot.
      • 6 Years Ago
      Pontiac trying to do what its supposed to do...be a performance division.
        • 6 Years Ago
        Agreed. I'm glad that the performance in Pontiac is still alive (given that the rumor about the G8 switching to FWD is unsubstantiated and probably untrue).
