Is there a GTO in any trim that can beat a stock G8? Was there ever any GTO like GXP or some special run like that? I was just thinking about this after running a GTO yesterday.

umm...pretty sure a stock ls2 gto would devour a stock g8 gt. stock ls2 gto and stock gxp would probably favor the gxp, but would be pretty damn close.

An M6 '04 GTO will be a hair quicker than a stock A6 G8 GT, an A4 stock GTO will be a hair slower than an A6 G8 GT

Stock M6 '05-'06 GTO will be about as quick as a stock G8 GXP M6 or A6, and will be faster than a stock G8 GT. a stock A4 '05-'06 GTO will be slower than either M6 or A6 G8 GXP, and will be slightly quicker than stock A6 G8 GT

if that makes sense

Although.... If it is a M05-06 you will take him off the line. (heheh, did the hubby and he wouldn't have done that voluntarily). Wheel spin is a bugger in the M6 Gtos

Thanks for the swift replies. bostonf4$ that made a lot of sense and helped a lot. I just have no knowledge on the GTO's and assumed the L76 was faster than the LS2. I know it isn't just decided on engine alone. Is the GTO substantially lighter than the G8 GT?

I think its 250-300 lbs lighter, but the auto tranny in the GTO is way inferior compared to the G8, that and the wheel hop issue others have mentioned puts the cars closer than numbers tell (GT vs. 05-06 GTO that is) but the GTO has shorter gearing from the factory too - and in most cases will be quicker. A tune only in the GT will erase that difference though

Thing is I don't know if any stock GTO's even EXIST anymore lol

True B, True B. But the tranny they put in the automatic for the GTO is a 4 speed which is weak to the power of the engine. Lots of Trannies being replaced for the car.

I think I did this right :)

A4 04 GTO < G8 GT < M6 04 GTO < A4 05-06 GTO < M6 or A6 G8 GXP = M6 05-06 GTO

**EDIT** I need to work on my math skills...there was 4 replies to this message before I could get that done. lol

Stock M6 '05-'06 GTO will be about as quick as a stock G8 GXP M6 or A6, and will be faster than a stock G8 GT. a stock A4 '05-'06 GTO will be slower than either M6 or A6 G8 GXP, and will be slightly quicker than stock A6 G8 GT

if that makes sense

Iv'e owned and M06' GTO and an 08'GT. The GT has a slight advantage on HP over the 04' GTO but because of the extra 300lbs of the GT, the GTO will be quicker. The GXP on the other feels faster than my GTO and according to all the pro reviews is quicker than a GTO in the 1/4 mile.

My buddy has an my06 m6 gto. Been wanting to play for a while but knew he would walk me in my gt. now that i got an m6 gxp should be more even and maybe even ad me. if it ever happens will post the results

Yes. My dad has an 06 GTO that roasted my stock G8 on several occasions. The chirps the tires in 2nd gear... and it's an automatic. Sadly, my dad never gets on it. He's retired and paranoid about gas prices. :)

I test drove a 04 LS1 6 Speed GTO back in the day and I don't think it was faster than the G8

An M6 '04 GTO will be a hair quicker than a stock A6 G8 GT, an A4 stock GTO will be a hair slower than an A6 G8 GT

Stock M6 '05-'06 GTO will be about as quick as a stock G8 GXP M6 or A6, and will be faster than a stock G8 GT. a stock A4 '05-'06 GTO will be slower than either M6 or A6 G8 GXP, and will be slightly quicker than stock A6 G8 GT

if that makes sense

Well, on the street the M6 would be quicker but at the track, the A4 would be quicker.

The minute you start modding, things begin changing. A cam only G8 has the potential to walk a cam only GTO. All due to the higher flowing heads.

Don't run any 05-06 GTO's stock, they'll jack you. Honestly I wouldn't run too many performance cars with a stock G8, it needs a tune at the very least.

Had an 06 GTO, and I've got a G8 GXP, both 6 speed manuals, the GTO felt quicker, much more likely to spin the tires. The GTO was a beast, very raw feeling. The GXP much smoother, civilized, and refined. I would give the edge to the GTO, 15 less horses, 300+ lbs lighter. Both cars stock!

Depending on how the race goes.

From a roll, if you catch him between the HUGE gearing gaps of the 4speed auto, you'll crush one!

I tailed one that took off in front of me and almost rear-ended him!

Definitely noticed this...I play around with my buddies 05 GTO with headers, intake and tune, if that trans doesnt wanna down shift he might as well let out of the throttle cause Ill be gone...or if it decides to hook lol.

If it has the dual scoops I know it is the 400 hp stock version, most of them will run you, the 350 hp non-scoop version should not be a problem for the stock G8. A manual dual scoop GTO once going is pretty quick, but very hard to launch, so I always race from a dig. I have not lost to a GTO ever. I did run one that I got off the line then he would catch me and lose me on the shift, then come powering back to fall again at the shift. I also ran a older GTO with a 400 v8 but it was actually slow.......

I've got an 05 M6 GTO with a predator tune, short shifter, K&N and 25K on the clock. The wifes G8 GT is bone stock except for a K&N....As has been pointed out, the Goat is really hard to launch with out lots of burned rubber....The GTO is a beast and is really really quick when you can get it to hook up and are used to the shifter...For sure, an inexperianced GTO driver would be smoked by a G8 GT and flat out whipped by a GXP. Driven correctly the Goat would take a G8 GT and beats the GXP by a hair. JMO

^25k on the clock?? Wanna sell? :P

Merc, LOL..nope, it's my toy but trying to stay as stock as possible as all the others i've seen are all modd-ed out..found it with 9K on it in 09.....love the wifes 09 G8 GT prem/sport though and have occasionaly thought about a GXP; can't beat the G8's look and ride, not to mention 4 doors!!

long article, this was an 05 GTO manual vs 06 Charger SRT8 automatic

GTO: 0-60 4.7 sec 1/4 mile 13.3@ 105.9
SRT8: 0-60 5.0 sec 1/4 mile 13.5@106.3

As the previous owner of a 04 A4 GTO, my car ran 13.4 to 13.5 at 104MPH all day long at NYIRP and Milan. No track prep and it was in the heat. I don't think my G8 (stock) would have beat that and that seems to be the case when I look at those of you who took a stock G8 to the track.

How would the LS2 perform? I think I would go with the rest of the guys in this post and say that the LS2 GTO will beat all versions of G8 including the GXP. And the A4 GTO's are usually slightly faster in the 1/4 than the M6. The M6 shines when you start with a roll race between 50 and 60MPH.

Stay away from any 05-06 GTO's. you will get them off the line because of wheel spin but they will burn you when they catch up.

Let me explain a little better....

The one I followed, slowed down and all but stopped as the car in front of him was turning left.

He had a passenger.

Passenger looked back at me just after driver spotted me in rearview mirror.

It was a yellow GTO, and it had dual exhaust (not single sided).

He jumped on it. (saw a puff of carbon)

So did I.

We get to about where I jump into second, and I had to lift or risk hitting him!

I got back into it, as he kept in it. I was back with him very quickly and we both lifted prior to triple digits.

Granted, he had a passenger, I didn't.

My only mod is a Cortex. Everything else is and was stock. I have no idea what his mods were, if any.

After about 2 miles, he pulled off and made a right, and they both waved and gave me the thumbs up out their windows!


Now, I don't know GTO's much, but is it safe to assume that there were two variants: Single sided exhaust and dual exhaust. Well, that and they were either M6 or A4, right?

Single sided and dual wouldn't necessary tell you anything. It could have been an 04 with the rear bumper switch out. There is a yellow one around here that is an 04 that has an 06 kit (hood and dual exhaust) that just has exhaust. Its an A4 04. If he had yellow letter inside the GTO most likely this was him. The passenger also would make a difference due to the extra weight.

I don't know.

Just stating the facts ma-am !!! lol

This was in the Kimberton area.

The Cortex makes a GIANT difference with our cars. I was stating stock vs. stock. Bet you ran into an LS1 with a 05/06 bumper. I believe that my G8 is now faster than my old 04 GTO with the Cortex and Vararam. Heck, some of you have hit low 13's/high 12's with those mods. However, I'd still put my money on an LS2 GTO over my G8 any day. Couple of kills from the GTO forum seem to confirm this: Stock LS2 GTO takes a tuned/CAI G8 GT by a car up to 120MPH.

Stock M6 '05-'06 GTO will be about as quick as a stock G8 GXP M6 or A6...

I disagree, sort of. I had an 05 M6 GTO and the GXP feels faster...and is faster at the track, at least for me. Of course the 3 tenths I picked up in the GXP was done at sea level rather than at 2000' in Vegas lol. Without a doubt I'd say it's a driver's race so long as there are no mods involved...

...but the GTO has shorter gearing from the factory too - and in most cases will be quicker.

GTO has shorter gearing than a GT...but the M6 GXP has shorter gearing than the GTO w/the 3.42 rear end IIRC...one big reason I get out of the hole as quickly in my GXP as I did in my GTO. Didn't you have a GTO? Your name looks familiar...

Had an 06 GTO, and I've got a G8 GXP, both 6 speed manuals, the GTO felt quicker, much more likely to spin the tires. The GTO was a beast, very raw feeling. The GXP much smoother, civilized, and refined. I would give the edge to the GTO, 15 less horses, 300+ lbs lighter. Both cars stock!

^This is a good description...but for me the shorter gearing in the GXP has given it a slight edge, or made it a VERY close race as far as I can tell...

**I should point out that my GXP has headers/intake but so too did my GTO...BUT my GXP hasn't been tuned yet so I've left a LOT of power on the table. Not exactly apples - apples but how I've modded I think the GXP is as quick, if not slightly quicker than my 05 GTO (my timeslips back this up, although at very DAs).

Guess all I'm saying is one isn't faster than the other - def driver's race!!

I want a GXP :( lol

My brother had a 2006 GTO with the 6.0 LS2 A4 sport package with a AEM CAI, superchips tune and SLP Loudmouth catback. My G8 GT had a K&N CAI, Cortex tune, and SLP axleback. We would race these down the street and honestly the G8 GT would start to pull in 3rd gear but would not gain much more than a half car. This was because my brothers GTO would not hook up, so I think a stock GTO with the LS2 would easily beat a stock G8 GT if it could connect to the road.

I traded my 05 LS2 A4 GTO for the G8GT. The GTO definitely screamed harder above 5000 rpm where the extra 40 hp showed up. Pontiac claimed 5.4 0-60 for a 2004 LS1 A4 GTO and 5.3 for the M6. However, they claimed 0-60 in 4.6 for the 05 A4 GTO vs. 4.7 for the M6 which I definitely believe having driven both the A4 and the M6. They mentioned that the torque converter was improved which helped the A4. The claimed 0-60 for the G8 is 5.3, equal to an M6 ’04 LS1 GTO.

The LS2 GTO was definitely quicker overall than the G8 EXCEPT, as some have noted, where the wide ratios of the A4 hampered roll on down shifts around 35-40 mph and 75-80 mph. At those speeds, the GTO would drop down to 2nd and 3rd, respectively, just like the G8, but the overall gearing was much taller in the GTO, contrary to what some have suggested. Yes, the rear axle ratio in the GTO was lower at 3.46 vs. 2.92 in the G8, but the A6's gears are all much lower and closer spaced than in the A4. This makes the G8 way more responsive and fun to drive than the A4 GTO in anything other than all out drag strip type running.

Below are the ratios for the 6 gears of the A6 and the 4 gears of the A4, with the overall ratios for the G8 and GTO shown in parentheses. The overall ratios are 11%, 22%, 31% and 39% lower, respectively, for each of the first 4 gears of the A6, with 4th in the A6 being almost the same as 3rd in the A4, and 5th in the A6 being almost the same as 4th in the A4. Needless to say, the low and high speed passing response is way better in the G8 which is one big reason that I traded the GTO for the G8. Under the circumstances, I personally do not miss the top end hp loss to the LS2 at all.

-----------1 -----2 -----3-----4----- 5----- 6

A6 G8-- 4.027-- 2.364 1.532 -1.152- 0.852 -0.667
--------(11.76) (6.90) (4.54) (3.37) -(2.49)-(1.95)

A4 GTO -3.06 ---1.63-- 1.00 --0.70
--------(10.59)-(5.64)-(3.46) (2.42)

LS2 GTO > Any G8 stock for stock

The minute you start modding, things begin changing. A cam only G8 has the potential to walk a cam only GTO. All due to the higher flowing heads.

tell that to this guy. heads, cam, gears, exhaust. no nitrous no FI.. yea GL but a g8 without FI/nitrous wont do this ;) mod for mod a G8 will always be quicker in the 1/4. most ls2 goats wind up weighing around 3600-3700lbs 300-400 lbs less than a g8 gt. the m6's have run 12.8 to 12.9 stock. and trapped 110 mph stock. the a4's have done low 13's around 105mph. there only draw back is they do not grip from a dig on there stock tires. no reason to think a car that has better power to weight ratio would be slower than a g8 gt lol.

A stock LS2 A4 will beat a stock A6 GT. My friend and I already did that race. Now with a tune I was able to beat him.

umm...pretty sure a stock ls2 gto would devour a stock g8 gt. stock ls2 gto and stock gxp would probably favor the gxp, but would be pretty damn close.

The stock LS2 GTO should edge out a stock G8 GT. The GTO is lighter (about 200 lbs) and has more HP (400 vs 361). I can say with certainty that a stock LS2 GTO should lose to a stock GXP with drivers and conditions being equal. My buddy owns an '06 M6 GTO with headers, tune, and cold-air intake. He is a helluva driver, and bangs the gears really well. His best ET was .005 faster than my best ET (12.916 to 12.921). When we line up head-to-head it is a pure driver's race. Whoever gets the better launch and light wins, because the cars are so evenly matched. If his car were stock, it wouldn't be so close.
