Are These Test Results True?

I believe everything I read on the world wide web. Bonjour!

The GT500 is light with more power so it should be faster! But on a track with TURNS, the ZL1 wins! And from every head to head I've seen...They always say it's because the GT500's brakes are only good for 1 lap.

That's why I came in here to ask.

I figured that, I was just wondering why it falls behind much more dramatically by 150mph.

I THINK I answered my own question, but I'm not sure. I played with an RPM/speed calculator and it looks like the GT500 gets to 150mph in 4th gear and 4th gear in the Shelby maxes out at about 170mph. The ZL1 reaches 150mph in 5th gear, and 4th gear maxes out at 144mph, 5th gear maxes out at around 180. So basically, the ZL1 has to chug and turn that bigger gear to reach 150mph, while the GT500 gets there in 4th.

Why does the ZL1 seem to hit a brick wall (according to these stats) by 150mph? Is it a gearing advantage in the GT500? Are the number skewed?

This graphic always amuses me. The errors of omission are laughable. In a straight-line, yes the GT500 with its lighter weight and +100HP are as you would expect. But what happens on road courses that this table fails to mention?

http://www.motortrend.com/road...

"While the Mustang was a half-second faster around the track than the ZL1 on its best lap, it couldn't repeat the performance. By the end of the first lap, the brakes had already begun to heat up so badly, we could smell them from the pits as the car passed by on the front straight. By the end of the second lap, the Shelby had lost more than half of its advantage over the ZL1, turning a 1:39.03. By the third lap, the Mustang was behind the Camaro, turning a 1:39.30. The ZL1, meanwhile, never deviated by more than two-tenths of a second."

"So, yes, the Mustang turned a faster lap, but if it's not repeatable, is it really a win? Find a 2.23-mile autocross and you might have something, but in any road race, the Mustang is going to quickly fall behind."

By the third lap the Camaro was in front for good.

How about Road&Track's test at Grattan Raceway?

ZL1: 1:27.91
GT500: 1:28.53

"Repeated braking into Turn 1 was a big test for the Brembos on both cars, and only once was there panic from a soft pedal. That pedal belonged to the GT500, which ended its timed lapping session after seven hot laps. The ZL1's brakes never faltered and in conjunction with the MR suspension provided superior confidence in decreasing-radius brake zones. The GT500 kept wanting to swing its tail out, causing a bit of trepidation and decreased speed."

FastLaps times for both cars...

GingerMan
ZL1 1:42.05
GT500 1:45.21

Grattan
ZL1 1:27.95
GT500 1:28.53

Sachsenring
ZL1 1:38.13
GT500 1:38.26

VIR
ZL1 2:52.38
GT500 3:00.60

Nurburgring
ZL1 7:41.27
GT500 0:00.00

So the GT500 posted one good lap time one one track (Laguna Seca) then quickly fell behind by the third lap. The ZL1 is faster around every other track tested.

Thanks for bothering to post that. I know I wouldn't have.

The nav is just about 4 pounds of dead weight for antenna and wiring. Some of these items may seem small but they all add up.

Where do you come up with these weights? The Glass roof option adds 20 pounds, the Recaros save less then 10 pounds and the floor mats weigh more then the NAV unit.

That chart reminds me of the GT 500 Nurburing video, mostly garbage.

still waiting to see affirmation from Ford that the car was in fact stock and the GPS log is being posted, rather than taking a blue oval enthusiast sites word for it...

Difference becomes very apparent on a longer track like VIR.

And there you go ...

You're an obvious Ford fan on a totally GM site. Were you expecting to have nothing but pleasantries posted about the blue oval? The "shit talking" is what keeps this fun. Sit back and enjoy the show

Exactly, straight and to the point. No sugar coating. Suck it up cup cake!
