A dealership employee somewhere has posted a pic of GM's inventory controls website in which the engine option for the 2009 Pontiac G8 GXP is revealed to be none other than the LS3 6.2L V8. To refresh your memory, the LS3 replaced the LS2 as the base engine for the Corvette this model year. In the Vette, it produces 430 horsepower from 376 cubic inches, or 436 hp if you opt for a special dual-stage exhaust system.
There was a time when the Corvette kept all of its components to itself, but that ended when they started building the Cadillac XLR side-by-side with the iconic American sports car and began using its engines in the CTS-V. Nowadays, Cadillac regularly pilfers the Corvette parts bin, so why not Pontiac, too? An LS3-powered G8 GXP would be just short of epic in its degree of awesomeness, so let's hope the internet is right on this one. Thanks for the tip, John!
