I heard some info over the weekend from an insider that they will be relasing a GXP version of the G8 with the Corvette Z06 powertrain. Has anyone else heard this?

There has been no confirmed reports of an GXP even existing.

Even if they did release one, the Z06 powertrain is too expensive to manufacture to warrant them putting in the G8. If anything, they might use the LS3 that is in the 2008 Corvettes.

Pontiac has made a big deal with GXP even being the top model of Torrent. It certainly would seem that they have left the door open for GXP version at a later date.

I am sure we will see a GXP version of the G8, I think the Z06 drivetrain might be too expensive. If GM did it I would probably still stretch to buy it but I think the LS3, or whatever they call the new Corvette base motor, is more likely.

That new motor (with somewhere around 410-430 hp) is going to be the largest gas Chevy small Truck engine so I assume the plan being tons of motors, extras to go all around.

The logical (& cost-effective) decision would be to use the LS3. Since the V8 for the GT will be lower HP than the GTO's, this gives them room to add a 3rd model.

Yup LS3 would be the next obvious choice for the GXP version. GM has the CTS-V to play in the 500hp $50k+ category. I sure as hell wouldn't pay $50k for a Pontiac.

Jay Leno had a sharp observation last night commenting on the new $100,000Lexus Hybrid. Spend taht much money for a car and you could care less what teh price of gas does since you don't have any money left for gas anyway.

a LS3 would be nice IF Pontiac decides to produce a GXP. I'm looking forward to driving a G8 and filling out an order sheet.

Ah, no. No chance at all for LS7, which dies soon.

Don't the next CTS-V and the Blue Devil Corvette get a supercharged LS7? I still think its too expensive to put into a GXP model.

The new CTS-V is rumored to have the ~ 500 hp supercharged LSA engine.

There's no supercharged version of the LS7 - it's a different engine

The infallible MT calls it an LS7, and also claims it to be s/c. As well as 600 hp in the CTS-V and 700 in the 'vette. (July 07 issue)

I am getting my signals crossed, sorry. According to the latest C&D, the new CTS-V is going to have the LS7 with 500 hp and the Blue Devil is supposed to be some 7.0 liter 600-650 hp monster. I thought they were going to use a blower on the Blue Devil, Z07, or whatever it is going to be called.

The speculation is that both the CTS-V and Corvette Z07/SS/Blue Devil will use the supercharged 6.2L. Apparently the Caddy will be detuned to around 600 HP while the Vette heads for the land of 700 ponies.

I'd love for the LS3 to be in the GXP. That would be plenty of power. They wouldn't drop the same engine into the G8 that the CTS-V has due to obvious overlap.

Whew. I knew I smelled something. Bull****.

The LS7 is scheduled to end production in a year or 2. The "Blue Devil" engine has been repeatedly referred to as a S/C 6.2L. The reason for lower displacement? They need cylinder wall thickness for the amount of boost they are planning to give. Of course, GM builds in a margin of safety.

When I read that in MT, I laughed to myself - the speculative bs that magazines come up with sometimes....

Agreed - LS7 cylinder walls is scary thin

IMHO, there is no way the next Z06/Z07 or whatever is going to have more than 600hp. for the past several years the Z06 has competed directly and only with the viper in terms of hp until the new cobra came along. the "updated" viper has 600hp, the next high end vette will be right there. besides, insurance rates explode when you get to that high of an output. want proof, call your insurance provider and get a quote for a new viper and a new vette. HUGE difference due to 100 hp. its just like to early 60's 427. they had to dumb them down just to sell them b/c of the hp.
now, that the hp wars are reaching such heights, price on new "high performance" cars overall will shoot through the roof, and you can bet your sweet (insert explitive here) that there will be some new "enviromentally irresponsible" tax. count on it.

If you can afford a $100,000 car, then the chances are that you can afford the insurance as well. The Vette will have 650+ horses.....

You can bet your sweet whatever it already exists. It's called a Gas Guzzler Tax.

the thread above entitled "possible GXP" has a possible GXP spotted in Troy, Michigan. Now why do you think Holden would have a clubsport R8 here in the US?, unless it was privately owned and imported.

It had manufacture plates on it though. Who knows?? Also some Lumina SS's rolling around which is the same as the Holden but with a Chevy badge. Nice looking car IMHO. Possible Impala SS, or mules for the G8?

Dude, that was like the weirdest post I ever read. A very wealthy person worried about insurance or taxes. With the performance possibilities of the regular GT I just wonder what 430hp will do. You could easily be looking at sub 5 second 0-60 times. I still wish for alittle more comming from the factory.

Rather than bringing in a preproduction unit prior to start of preproduction (July 4) and disguising its appearance they simply chose to "hide in plain sight". What has been sighted is 100% owned by GM for whatever purpose and not a private vehicle. The waiting period, the individual car EPA testing, the bond posting, to import a 2007 vehicle that is not approved for sale in teh US, even if all the hoops could be jumped and the red tape slashed you are looking at a final cost of getting a $40,000 car here and legal at about $250,000. That insane amount of money would certainly scare up the keys to an Maserati Quatroporte.

The new "SS" vette is pretty much assured to be a supercharged LS3. Extra strength in all the areas needed for boost but in stock form.

I think if they do come out with a GXP G8 it will be 2 or 3 years after release and will probably coincide with a styling update and hopefully a coupe version.

The viper has 650 horse in it without any problems. DCX detuned it so that it could continue the horsepower wars with GM when they released the Blue Devil. GM knows this and will be able to beat the viper again. All of the major manufacturers buy the others products, chop them up, look at them, and take the engines to their max just so they know what they are up against.
