99-05 vs. 2005 Specification Comparison

[351CJ]

Styling aside, the specs for the 2005 Mustang GT seem to blow away the 99-04 in almost every aspect. I especially like the big brakes, 2" wider track, longer wheel base and better F/R weight distribution.

I was expecting more than 1 inch more rear leg room, but oh well...

THe tires on the 05 are a lot taller, they went from a 45 series to a 55 series. THe base Mustang GT tires won't even be low profile

compression ratio has increased from 9:4:1 to 9:8:!...that will lower our abilities to squeeze more boost on a stock engine (ie S/C) ..am I right ?

With a good amount of boost, your going to have to change to lower compression pistons anyway.

if those numbers are right, the new car is longer, narrower, and taller....

might just be me, but i think thats a bad combo...

Longer, narrower, taller body ... yes. But the track width is two inches wider, the wheelbase is six inches longer, and the weight distribution better. These are all good things.

What I don't like is the horsepower/torque numbers -- sure, the peaks are higher, but look at the RPM jump. I'd like to see more torque at a lower RPM.

With the variable cam timing - VCT - torque should be significantly better at lower RPMs.

When VCT was added to the Lincoln LS 3.9L V8, peak torque increased by 19 lb ft, but @ 2,000 RPM it increased by 26 lb ft and @ 3,000 RPM it increased by 30 lb ft.

With all the curves in the body, maximum width can loose its importance. I just measured my 2001 GT. The maximum width (not counting the mirrors) is over 73" and it occurs right at the front of the rear wheel opening bulges. The width across the front fenders (again maximum at the buldges) is less than 70".
The outside of the rear wheels is 2" inside the fenders at the maximum width point.

HairyCanary is correct, the track width is the important dimension and with the 2005 it is 2" wider both front and rear.

As far as the height goes, a 1/2" difference is really insignificant.

Man I had forgotten how bad the weight distrubution in the current GT was. There are gonna be a lot of ricers who are going to be surprised in this things slalom abilities.

 

[Stangston]

Wow looks like the new car is still essentially a 2 seater? The rear leg room is not practical in the current car for friends, and an extra inch doesn't seem like it'll do much. And is the rear head room correct? Less than the current model...is that even possible?

I have to kind of lie down in the current model to fit in the back. I can't believe this wouldn't be a target area so that the car could suit a wider market.

 

[Omegalock]

It looks like the additional length in the chasis is more in the trunk(and likely in the engine compartment). I would think the head room being less would be attributed to the tear drop roofline.

You can think of it this way. Compared to the old car, everything stays nearly the same except the front wheels move forward. So the engine is now more behind the front wheels. This is how the weight balance goes from 57/43 to 53/47 (F/R).

From what I've seen so far I'd guess that 4" to 5" of the 6" longer wheelbase is the front wheels moving forward and 1" to 2" of the longer wheelbase are in the passenger compartment.
