Alright guys I plan on buying a G8. I was woundering if anyone knew if a GXP version will be made. I would hate to buy one in a couple months when they come out and then have a GXP available after I buy. I have heard alot of talk about a GXP "ls3" and was woundering where it was all coming from. Thanks

Im not sure how accurate this is but I thought i heard they were planning on releasing a gxp version the second year of production on the G8's. Could just be over eager speculation.

I would expect a GXP out about a year or so after initial introduction with a LS3.

I heard '09, LS3, from several people with some connections....but there's nothing official so we really don't know yet. Might be worth it to wait anyway, as perhaps the GT prices will be lower (certainly at resale) if a GXP comes out.

I heard you shouldn't count on anything mentioned in this forum actually happening. 99% is speculation.

that being said the only things confirmed so far are a V6 and a 360 some odd horsepower 6.0 V8 (not the LS2!!!!)

Did you know that 93.7% of all statistics are made up on the spot?

People are speculating based on GMs past. first off, they release the new V8 motors int he corvette the first year, then they use it in other models the following year. the LS3 is coming out in 08 in the corvette, so that leaves cars like the camaro, G8 and a few others for 09.

also Gm tends to release new cars, then when the interest dies off after the release year, they offer new options the second year. thats typical for convertibles or larger engine options.

In addition, the pontiac division has been making a GXP model for all of their cars lately, so a GXP version of the G8 is almost definite. which engine is not clear, but its a good speculation to assume itll be the LS3, and the HSV body panels.

As long as they don't give it the GXP treatment that the G6 got that was all appearance and no performance haha.

Not a chance. It will most likely be the LS3 but by the time the GXP comes out who knows what GM will be pushing out there. The L76 will be the GT motor which is essentially a LS2 bottem end with a L92 head and manifold. It will be tuned down a lot to run 87 octane (tuner car for sure).

I am worried also that if I buy a G8 GT that I will regret it when the GXP releases like a year later to re-up interest in the vehicle. But, that being said, I feel like the GT will be a great tuner car and as an ex GTO owner and a current TBSS owner, my style is a little more on the sleeper side. So I think I might be happier with a slightly understated appearance anyways. The possible GXP performance upgrades over the GT will also come with appearance changes I am sure on par with that of the G6 GXP or similar and that is just not something I want. I would rather mod it to my liking (which I would do anyways) and not have the "look at me" styling that will probably come with the G8 GXP. Just my 2 pennies on the subject.

^ thats why i plan on getting a 2 year lease on a g8 gt asap and then buying the gxp.

question,

doesnt ls3 only have 20 more horsepower?

the new g8's are hot, and have a real backseat, and with a 6 speed?!? i'd be all over that in a heartbeat if i could afford it.

Me and my wife are planning to get the GT sometime next year. GMHTP claims that they come w/ a conservative fuel/spark tune (as usual in LSx/L76/L92/etc) and that a tuner w/ updated software might be able to get up to 40 more hp out of it. 362 + 40 = 402 LS3 - 425-ish. I'll sacrifice less money for 20hp.

Thats true the 361HP is actually on 87 octane.. throw in 93 and tune and viola.

:D I'm sure you'll see 40HP alone on a tune. This motor has tons of potential. :devil:

Slated for 2008i/2009, has the LS3...but the car i drove had the automatic. :(

Not sure if this rep. just didn't know what they were talking about but I went to the LA Auto Show last month where they had the G8 GT on a rotating pedistal with the doors open and I asked the rep. if this Holden made G8 GT was going to have the LS3 and they said it would not. They informed me that the G8 GT would be running on some 6.0L truck engine with the same capabilities of the LS3... of course they could give me no explanation as to why they are not using the LS3. Where these reps at the auto show on crack or can anyone verify this?

The GT version was never going to have an LS3. If t here is a GXP version the LS3 might end up in there.

My question is, why pay extra for the LS3?

I understand that the Vette is going from the LS2 to the LS3, giving you the L92 heads and more power potential out of the box. But the L76 already has the L92 heads. It just has a slightly smaller bore. With the same mods (cam, ported heads, headers, tune), the L76 will be very close to the LS3 at the end of the day.

The GT will be cheaper to begin with, thus leaving more money for the power goodies anyway. Unless the GXP will come with bigger brakes, better suspension, why pay a few grand more for essentially the same car? Sure, it may have another 60-70HP off the showroom floor, but with the same heads and manifold, will 12cid really make a huge difference once some mods are done?

I'm really looking forward to the GT, but I won't be sorry if the GXP comes out with the LS3 and is another 3-4k more. The only good news is that the GTs will drop in price some in the resale market.

I agree. I'd bet the GXP would be $5k+ more than the GT. I'd guess you're a CAI, Headers, and a tune away from 400+ to the flywheel in the GT. Add a cam to the mix and you've probably surpassed the LS3's numbers.

And you could mod the LS3 to even higher numbers.

Hopefully the general's new cars will be like the olden days when you could get a base V8 and mod the shit out of it. :)

I was reading on motortrend when they put the c6 z06 motor in an hsv version and in the article it said something about the new 425hp g8 gxp version. Im sure thats speculation but thats what i was thinking it would be around LS3 territory. http://www.motortrend.com/features/performance/112_0712_hsv_gts/

Right, but you've still spent an extra $4-6k on a GXP.

Screw it...buy a GT and slap a Procharger on it with the money you save over the GXP.:devil:

I heard from a reliable source that the GXP will be a 4 door corvette.He works for GM and was just at the big G8 show threw dealers,They didnt tell him specifically what engine will come but when he asked about the LS3 they smiled and said again it will be a corvette with 4 doors :)

I have some one picking my car up at the end of the month. Once it is gone I am saving up a nice down payment for the gxp!!! If it does not come out I will get a GT and already have money for mods, so Im ready to go!!!
