Default Difference Between G8 GT and G8 GXP?

What extras is the GXP going to get over the GT besides the LS3?

The GXP will be loaded from the factory. Leather seats, heated seats, power everything. They won't have any base model GXP's. More than likely the only options will be whether or not it gets a sunroof and a multiple disc CD changer.

Main thing is the LS3 engine but also includes slightly different bodywork, wheels, brakes, suspension, seats and some other small accents.

Yep they also have oil temp and pressure guages, larger diameter brakes, like 14" IIRC.
3.7:1 M6 gearset. Uprated suspension, larger wheels and tyres. 275"x19 rears.
Bodykit etc. Think AMG vs Merc and M Series vs BMW.

Where did you read that about the tires? All I've heard was that the tires will be 245's.

The official list is as follows: (You can get this from Pontiacs website)

19" 8-spoke wheels
Flared front and rear fenders
6-speed manual, or 6-speed automatic
LS3 sourced from the Corvette and Camaro programs producing 402 at the crank
Full leather bucket seats, embroidered with "GXP" logos.
Exterior GXP badging.
Full cat-back exhaust specific to the GXP.
(Possible) standard two-tone seats to match the exterior of the vehicle.

You cant get the plain GT here. The GXP would be over $60,000 US!
17.5% sales tax doesnt help.

I got mine for mid $50k range with 5000 on the clock.

The car is excellent. Mods already started. Running mafless with over the radiator intake. Stroker on the way..

Im happy with my GT. With the money I saved by not buyin a GXP, I could use it on performance parts and be over 400hp. I do like the wheels and brakes though

About 10,000 dollars. That's the main difference between the GT and GXP. I read recently that the GXP is likely going to start at about 40k.

In addition to what's already been mentioned, XM radio and a better placed seat-back tilt control ****. When I test drove one, I remember the **** was too high up on the seat back, wedged between either the door or side panel.
