Just to catch you up, when it arrives, the G8 GXP will feature the Corvette’s 6.2-liter V8. Autoblog is claiming 402 hp and 400 torques, though we think they’re leaning a bit conservative. Especially since in Vette tune that mill makes 430 hp (or 435 with the trick exhaust) and 424 lb-ft. Regardless, a nifty feature of the LS3 is that the manifold is made specifically for forced induction (hence the ZR1’s supercharged LS9 and the Caddy CTS-V’s force-fed LSA), meaning you just know that tuners are licking their chops to get the GXP spec G8s into their shops. Perhaps even more important is the third pedal and six-speed shift-for-yourself mechanism, both of which were captured in this Aussie test mule. You’ll also note the quad pipes. Fade-free Brembos appear to be par for the GXP course, too. 2010, you can’t come too soon. [Cheers on you, Autoblog]
