Pending final testing, the G8 GXP is expected to deliver 0-to-60 mph performance of about 4.7 seconds, and a quarter-mile time of 13.0 seconds at 108 mph.

According to Pontiac, the G8 GXP runs from 0 to 60 mph in about 4.7 seconds and covers the quarter-mile in 13.0 seconds.

http://www.popularmechanics.com/blogs/automotive_news/4254520.html

Expect the better breathing, hard working engine to help the GXP hit 60 mph right around 4.7 seconds, and reach the quarter mile in 13 seconds flat.

I hated history in school. Who cared who did what back in the 1400's? Yea Columbus (supposedly) discovered America.

As I got older, history meant not making the same mistake that others have made. Or if history showed someone did good, to follow that person, but in an updated context.

I had a 2005 A4 GTO.

Loved the car.

The only things that bothered me was:
A lack of an interior door lock switch.
I felt that Pontiac led me on with quarter mile times in the brochure.

I made a post in the GTO forums about a quote in the brochure about turning an "immediate 13.0 @ 108 mph" in the quarter. I think it also showed turning an 4.7 in the 0-60 run.

I don't know of anybody on the GTO forums that got an immediate 13.0. No way, no how. Some reached that lofty goal, but nobody got an IMMEDIATE 13.0.

Maybe it was my fault for seeing things as they supposedly were and taking their word 100%.

I will say that the G8 GT has stated 5.3 in 0-60 and Car and Driver backed that up with the same time, which is good.

Learning from history, Pontiac gets an F with times on the GTO and gets an A with times on the G8 GT.

About the times on the G8 GXP, I will wait to see what the different magazines come up with. With the GTO, I felt I was lied to, but on the G8 GT Pontiac got some of it's integrity back.

At the end of the day, I didn't so much mind Pontiac telling me that the GTO was a 13.0 second car, I minded them telling me that it was an IMMEDIATE 13.0 second car.

The auto rags were testing the car at about 13.3.

More than anything else, I blamed myself for buying their BS, I thought they couldn't advertise something of this nature without some government agency making them back it up.

I am not trying to rain on the G8 GXP parade!!!!!!!!!!!!!!!!

The whole purpose of this thread is this...............don't hold Pontiac's times of 4.7 and 13.0 as complete and total gospel. Don't go tell your amigos that you just purchased a car that will turn a 13.0 in the quarter, then have them meet you at the track and you turn a 13.6 and then have to listen to their crap.

I almost leased the GTO, but backed out due to the crappy residual. However, when I was still researching it, I remember the same scenario as you and I also remember one of the mags- I think it was MotorTrend- finally getting the car to perform the way Pontiac quoted, but it was ridiculous what they had to do! The only thing I can recall for certain is that they put a big bag of ice on the intake manifold after the engine was completely warmed up and they power-shifted every gear during the run. (You know, just like the typical driver would do every day, right?) But other than that, not one mag that I read at that time quoted a sub-5.0, 0 to 60 time for the 400 hp GTO.

If it makes you feel any better, at least the car was capable of those times. I didn't record my best drag time until my second year with the car. Time of year & location may have had something to do with that. And, I haven't had my car tuned, or any bolt ons (not even a hi-flow air filter). My best has been a 13.02

The GTO was a 13 second car. A professional driver achieved it, no doubt. You're not a professional driver. Everyone thinks that they can just get into a car and drag. Then they hit the track and can't figure out why they aren't instant stars. Gee, maybe I've gotta practice... ;)

The LS2 GTO is a 13.0 second and it has been backed up. There were even a couple that I know of that were in the low 12.9s. With that being said, there are many factors that go into a 1/4 mile time. The times can be affected by driver (main component), weather, altitude, track prep, and slight differences between cars (to name a few). Was the LS2 GTO a thrirteen flat car on average, no. To many factors had to be right. But if the conditions were right, you would get an immediate 13 flat. Is what Pontiac claimed untrue, no. It is a matter of semantics.

Look at what Pontiac claimed for the LS1 GTO.

1/4 mile 13.8
0-60 5.3

Look at what the mags reported

Car & Driver
1/4 mile 14.0 @ 102
0-60 5.3

Road & Track
1/4 mile 13.8 @ 104
0-60 5.3

The 2004 GTO seemed to be spot-on.

The 2005 GTO was not far off.

Pontiac claims
1/4 mile 13.0
0-60 4.8

Car & Driver
1/4 mile 13.3
0-60 4.8

The results are the first ones that came up when I searched.

If you expect everyone to get the claimed times every time, I do not know what to say. It is not going to happen.

Just race at ATCO. You will get your 13.0 :gr_jest:

End result: Pontiacs claims have not been far off. IMHO

The 2005 GTO was not far off.

Pontiac claims
1/4 mile 13.0
0-60 4.8

Car & Driver

IMHO .3 is pretty far off.

My best BONE STOCK time was a 13.6 at Houston Raceway Park (HRP) in the summertime. HRP=good, summertime in Houston is hot and humid=bad. Had I driven with more experience and in great conditions, I feel like a 13.2-13.3 would have been possible, but I don't feel like I could have ever made a 13.1 or faster.

I HIGHLY RESPECT those drivers who were at 13.1 or faster bone stock, but looking at the drag racing section on the LS1gto forums for over 2 years, it looks like those times are in the vast minority. There are many times I have read about some first-third timers to the track that were in the low 14's to high 13's, then they graduate to mid 13's. My problem has always been the claim of IMMEDIATE. As far as I know, nobody ever got an immediate 13.0, and very few got a 13.1 or lower that was not immediate.

Yes, many factors are involved, track conditions, weather, driver skills, knowledge of the car, break in period for the car, and so on. I only made two trips to the track bone stock, then went out and bought my first set of Nitto's. My driving skills improved enough that my car was number 1 in the super stock on two occasions, then I sold her. The guy who bought her (Flashover) took about 400 pounds off her and the car is again sitting in the number 1 spot with an 11.90 with stock heads and cam.

No matter that my driving skills improved greatly, I feel strongly, as stated above, that I would have never gotten her faster than 13.1 with drastic weight reduction, but that would not be IMMEDIATE. and I consider 'bone stock' as it is right off the floor, with spare tire and no weight reduction.

You aren't getting it. When the car is labeled "13 second car" that means that the car is capable of hitting it. It speaks not of the driver that gets behind the wheel.

Maybe they ought to put a five year old behind the G8 and see what he gets in the quarter mile. Then advertise that.... At least it will be accurate for the worst of drivers.... hehehehehe

Seriously though, nobody should have tried to convince you that its an immediate 13 second car. They should have said its capable. The G8 GT with a professional driver is capable of 13.7. That doesn't mean everyone that gets in is going to get 13.7 on their first shot.

More to the point, who cares? Unless you're running for money at the strip it really doesn't matter if its a 13.3 or 13.0 car, does it? I'm sure its plenty fast for the intended market. What other car has 400+ HP, carries five and costs (we think) below $40k? Not RS4 Audi, not BMW M3, not Mercedes C63 AMG, not Infiniti M45. In fact, no one else out there.

More to the point, who cares? Unless you're running for money at the strip it really doesn't matter if its a 13.3 or 13.0 car, does it?

It matters to me. If Pontiac is telling me that I am purchasing a car that does a quarter in an immediate 13.3, I expect something real close to that. I guess I see it as false advertising if it doesn't.

Like I stated earlier in this thread, this thread is not to rain on the G8 GXP parade. I just want people to know that if Pontiac states 13.0 in the quarter mile, not to expect it, or not to be upset if it doesn't.

With the 2005-2006 GTO, history shows that the brochure was about .3 off I know that in the future someone will purchase this car, expecting what Pontiac advertised and will be off by .5 or more, and they will come to these forums wondering what is wrong. It happened with the GTO and will happen here. I just want to pre-warn them that there are a lot of variables in getting great times at the track. Trust me.

Seriously though, nobody should have tried to convince you that its an immediate 13 second car. They should have said its capable. The G8 GT with a professional driver is capable of 13.7. That doesn't mean everyone that gets in is going to get 13.7 on their first shot.

There it is!

OG,

Here's how it works at GM. Once all the specs are nailed down on the car, the Proving Grounds guys experiment with launches to get the most performance from the vehicle. The reported numbers are real, as GM doesn't like class action lawsuits from misleading data. Sorry you aren't able to duplicate the numbers.

Very few were. I am also not a professional driver like the Pontiac guys are.

I guess I can't get past the word immediate.

You can not seriously believe everyone would be able to pull off an advertised time. I know your problem is with the word immediate. But come on, did you really expect that to mean that everyone should be able to pull a 13.0? To me, immediate means without changing anything on the vehicle. It means a showroom stock GTO is capable of a 13.0. Not every showroom stock GTO, but some. It seems you are just sore because yours was not one of the strong ones.

Life's too short; move on. :judge:

im·me·di·ate
1. occurring or accomplished without delay; instant

Yea, I took the meaning literally, being an absolute. Same as if I purchase a gallon of gas, I expect a gallon. I figured that 13.0 was a mid range run, where really outstanding drivers would get a 12.8 and the car would average about 13.0-13.3 with regular drivers. Even the car magazine drivers could not get 13.0 in their car tests and this is an absolute. Now if those drivers can't get a 13.0 at their tracks and their knowledge of driving, how can the regular guy get much better, or even as good?

I was wrong for taking immediate 13.0 in the literal context.

I have seen too many posts on ls1gto.com where drivers couldn't get near the 13.0. Unlike the advertised GTO immediate 13.0 runs, this is an absolute.

About being sore that my car wasn't one of the fast ones, of course I was. I expected no worse than a 13.5 (giving Pontiac a half second as a benefit of the doubt) my first times at the track, and the best was on my second trip at a 13.6. Then I started modding and it became one of the fastest ones in the super stock, fast enough that it was sitting on number 1 spot in the country on two occasions and with a new owner is back to the number 1 spot.

I can't help but wonder if anybody who loves cars were to by any car where the seller states 13.0 on the quarter and they can only get a 13.5. Hell yes people would at least wonder what is going on. I know I questioned my car many times. Was it my driving, was my car not as solid as other GTO's?

My whole purpose of this thread was to warn future buyers that if Pontiac posted 13.0 for the LS3 G8 GXP, not to be disappointed if they didn't get it and to let them know that these times are not an absolute. I wanted to warn them that racing has many variables. I wanted them to learn from my mistake.

I am happy that Pontiac stated a 13.8 for the G8 GT and the magazines also mirrored the 13.8. This is accurate advertising on Pontiacs part.

Let me repeat my whole take for you MENSAS.

I wanted to warn them that racing has many variables. I wanted them to learn from my mistake.

It isn't rocket science.

I think it's that "immediate" part that's the hang up. One thing to remember is this, some people haven't owned a car with this kind of power. Their skills may be a little lacking to drivers that have taken to the track many times before. I'll agree, the engine break-in period may be holding the car's performance back some. But, owners will also be willing to keep the car beyond the break-in period & run them at the track. Loosening engine + practicing driver = 13 second car. I don't think anyone should be mad if the car won't do 13-sec. quarter-miles with 100 miles on the clock.

What everybody should be looking at is the trap speed , 108mph and a regular guy should hit some where close to that mph with a GXP .

But it takes a good driver, good track and a good launch to get the times .
If the car does run 108 mph we should see high 12's at the tracks from good drivers .

The "immediate" thing is all relative , with my old Evo8 same day/track/tune/gas/driver...
my runs could vary from 12.3's to 11.7's but the mph's(115-117) were all close . The whole time I had a 11.7@117mph car I just to drive it right . Just have to find what works the BEST and thats not usually the 1st(or 2nd or 3rd..) try.


Re-read the 1st post , Its all most like Pontiac is saying a "stock" XXXXXXXX can run these #'s so no need for mod's to get there just good driving/track/weather .

It takes practice in any car. Rarely can you jump into a totally different car and achieve a best in one pass. My '04's very first pass down the track was a wheel hopping 13.6. I whittled that down to 13.2 before I started modding but it took 4 trips to the track to get the launch down right.

The LS2 GTO and G8, for that matter, would take a little bit of time also.

…
I am happy that Pontiac stated a 13.8 for the G8 GT and the magazines also mirrored the 13.8. This is accurate advertising on Pontiacs part.

I agree.
I think that ( as I have posted a couple of times here & elsewhere ) GM \ Pontiac did come to a realization that their published times needed to be much more realistic – and something that could be duplicated with relative ease, in the ‘real world’, by real drivers – meaning: customers, as well as the test drivers for the various publications.

And I am sorry you were a victim of their previous ‘strategy’.

Ready to experience 13.x . .

The problem with advertising performance and then finding out through automotive publications such as Car and Driver that the car is indeed slower is that it deflates peoples anticipation for the vehicle. I for one, am waiting to see what this car will do when it hits production because I cannot wait to dump my SRT8 due to horrible (to put it mildly) dealer support.
The Germans are the best ones when it comes to pre-production hype. They always publish 0-60/0-100 and 1/4 mile times that magazines beat by a couple tenths. People who follow this appreciate the conservativeness and it builds anticipation. I hope that Pontiac is following the same path.


BTW- This is my first post here, and I hope to become a regular contributor to the G8 forum. Most of all, I hope that the G8 lives up to the hype of being a top end domestic muscle sedan. The world needs more of them. :)
