The 2013 GT500 could very possibly and most probably will be faster than the ZL1...it should be with a huge weight and HP advantage, but not by much. The advantage is that Ford now knows what the performance of the ZL1 is, they WON"T release the GT500 until it beats the ZL1. They did that with the 5.0 Mustang. When the Mustang 5.0 was in it's planned production configuration, it wouldn't beat a Camaro SS and couldn't match the HP...what did Ford do, they added Tubular headers and Ford racing CAI. That gave them the slight advantage they needed. The GT 500 will follow that pattern.

The thing is, no one, even other publications, have gotten 11s yet. motor trend can make excuses all they want, but until 11s are out there, the times we have are 12.1 and 12.3. If I am not mistaken 11 and 12 GT500s HAVE been in the 11s bone stock, so again, if a private owner gets a ZL1 into the 11s, it is still only matching the 11 and 12 GT500. Also the GT to SS is a totally different scenarion. HP and torque wise they are VERY close, the GT500 and ZL1 not so much. It is only logivcal that the one packing and extra 70 HAP and 300 pounds less weight is going to be quicker.

Really? Do you have any links to this story?

Please show me pictures of this factory CAI for the 5.0L

The video that was posted today produced 0-60 in 3.8 seconds and high 11's on an unprepped surface in warm weather. He pulled off an easy 12.1 with the launch control on the same unprepped surface. He was also still lifting to shift on the runs. The ZL1 has a no lift shift feature. This could have cut the times down also.

11.9 is the best gt500 run on a prepped track with Evan Smith driving. The ZL1 is slightly quicker on stock rubber no doubt. You really dont think a private owner will best this recent high 11 on a prepped track and more seat time with more favorable DA?...think about it.

To me it is obvious the current ZL1 edges out the current GT500 in the 1320. But will have a big problem with the 2013.

What size tires come on the 2013 GT500?

Both sets remain the same as last year.

It works out being less then an inch in with vs the ZL1 and uses the same F1 G2's.

Not exactly what I am saying at all, I hadn't seen the 11.9 and was going by the article. I can see maybe a couple 10ths difference so all out with perfect drivers it may just have a slight advantage over the 11-12 GT500, on average though, probably not. I do agree about the 13 GT500, think it will be a very big problem and opretty easily the quickest, especially if the launch control is all they are claiming it is.

I think the auto is the one to watch for that's when you will see the best numbers.

I am sure GM benchmarked the GT500 and the ZL1 is slightly faster. Not sure why they would produce it if it wasnt. All in all it will be a drivers race though.

I do disagree though on one point. On average with stock tires the difference will likely be even greater. The Current GT500 is far more traction limited with the stock rubber/set up. The video showed just how easy it was to break off that 12.1. It took Evan Smith and a prepped track to do something similar with the 500.

Not to mention..auto zl1 vs gt500 on the street will likely be ugly for the 500 owner.

I forget about the auto, and I agree that is easily the one to watch out for.

no offense, but that doesn't tell me anything. lmao

was looking for the full tire size specs (ie 285/45/19)

Base GT500: 255/40/19 front and 285/35/19 rear F1 Supercar's

GT500 w/ SVT PP: 265/40/19 front and 285/35/20 rear F1 G2's

Awesome! thanks BigDan

2011 Mustang GT500


Car & Driver 12.4
Motor Trend 12.35
Edmunds 12.4
Autoweek 12.3
Road & Track 12.4
Muscle Mustangs and Fast Fords 12.02 (using their best driver and every trick in the book)

Even if the 100 hp brought times down by 4/10s second, we're looking at 12s or about what the ZL1 will do (Motor Trend video today says the ZL1 ran under 12 seconds on a crappy track). It's going to be an interesting comparison. No one has tested the 13 GT500 in production form, so for you to say "multiple magazines say it runs mid 11s" is kinda speculation. The basic suspension for the 13 GT500 is basically the same as the 2011 "with minor tweaks".

MMFF ran a 11.95 @ 120.77 in a stock 2010 GT500.

The 2011 was faster. Just had to be at the right track with the right DA.

Put a tire on both the GT500 and the ZL1 and run them.

Racing 500hp+ cars on anything less than Drag Radials is retarded either way.

When you say, "on the average" you mean by taking the slowest gt500 time and the fastest zl1 time. The zl1 is no doubt faster than the '11-'12 gt500, but half a second average is a bit generous considering only one zl1 has run faster than a 12.0. I also don't remember hearing anything about the 5.0 not being powerful enough in it's original form. In fact, I remember hearing the 5.0 in the GT was tuned down slightly to leave room for the Boss and more headroom for the gt500. Assuming suspension changes for the 2013 are minor tweaks is also a bit of a stretch. If they were to only put in beefier control arms and stiffer bushings, combined with launch control and considerably taller gearing, these additions alone on a '12 gt500 would put it into the 11s on stock tires. Now add the 5.8. There are many ways to increase traction on the gt500, just check out their forums. Now when ford is spending the money to add LC, a new differential, and a revised transmission for quicker acceleration, you'd think they're probably going to do the simple suspension upgrades that will help too.
