2015 Mustang mule testing IRS spotted
#141
Sounds like a good argument for beam front axle, simple drum brakes, three speed trannies and single cylinder motors over all this complicated performance stuff Mustang's have been saddled with over the decades.
Honestly, IRS's are anything but delicate cutting edge technology these days -- well, to the rest of the world at least -- and Ford will undoubtedly design a strong, reliable and effective one for the Stang, especially knowing the SRA mavens will take after Ford engineers with their stone axes should the IRS even hint at any strength/reliability issues.

Hmm. If I had ever known it was called the "S550", I had forgotten it. Wasn't there some rumors that it was internally called the "Mustang III", much to everyone's chagrin?
I don't have the great disdain for chrome that most people seem to have. I think it looks fine, if it's tastefully done and in moderation. It does seem that the alleged presence of chrome jibes with the old rumors that the "S550" will be more upscale, which I'm not so sure is such a good move.

I suspect "Mustang III" was probably used unofficially for two reasons. Firstly, it would signify a significant change in direction (think '73 to '74 - but this time done right!)
Secondly, they probably knew full well the web forums would be buzzing with Mustang fans wringing their hands at the thought of another wimpy donkey for 2015 (even though it WILL be done right)

About this whole issue of chrome on the taillamps... I have already seen an advance in chrome plating technology that allows light to shine through a plated lens when lights are on but looks like solid chrome when light behind it is off. It has already appeared on some aftermarket accessories, most notably lighted receiver style trailer hitch covers in the shape of a truck brand logo like Ford, Chevy and Ram. They also have replacement body emblems that light up.

With the old IRS cobra you could beef it up and they still would break. The solution...put in a solid rear.
I agree we still haven't seen what they're going to do. I'm just as eager as anyone else to see what ford does since they've done amazing things suspension wise with the boss, raptor, and focus svt.
Still I'm old school and you can't beat a stout solid rear axle for high HP. That's my opinion.
#149
THAT would be interesting, but perhaps more so on a halo performance sports car ala the Vette or Viper. Might I suggest a neo Pantera, Ford Product Planning Division?

A solid axle is better for drag and reliability. When set up right it handles very well. I am not a road course guy.

Unfortunately, that one heroic but inevitably cobbled and compromised imlementation of an IRS on the Stang did sour many on the very concept.
However, the Cobra experiment was but one instance and there is a world of highly successful IRS cars that belie the idea that IRSs are instrinsically detrimental to what a Mustang is or can be.

Another thought: based on the availability of the 2-mode adjustable suspension and Lincoln's Drive Control, it makes sense that we could see some iteration of a dynamic damper/MR system on the S550 car in a few years.

Also, I can't help but fear that the IRS implementation will turn out like the manual transmission.

Just to defend the IRS in the Cobras a bit. I wouldnt say they are crap, they did a fantastic job designing an IRS that fit in a 1979 chassis car that was never thought to ever have anything but a solid rear.
The IRS hold up just fine in my estimated 430-440 rwhp car, any many other more powerful cars. You just have to make sure to get out of the gas if you feel any sort of wheel hop.
There are more than a few IRS 9 sec Cobras out there.
Is it a world class suspension? No, but that isn't the IRS fault its the limitations of the chassis and cost that the Mustang had to satisfy.
To think that Ford was able to sell the 2003 cobra for low 30's compared to the 07 GT500 that was 10k more yet didn't have as many unique features(IRS, folding mirrors, unique side skirts, power adjustable seat bolsters)

The cost argument is bogus now because the Mustang's competition ( Camaro, Challenger) both have it for around the same base price as the Mustang.

Agreed, I mentioned cost because I'm sure it is much harder to design and implement an IRS on a car that was never designed for one than put one on a chassis that was designed for it.

Also the live axle for drag racing is a valid one, the Mustang has considerable presence in the sport. If you take all of Mustangs road racing efforts combined, it still doesnt match the number of drag racers out there ( a cursory look at any of the magazines featuring modern Mustangs will typically feature articles focused on acceleration, you have a number of national dracing events, et al)

My only addition to this topic, would be for everyone to keep in mind that Ford is extremely committed to lowering the weight of the next gen Mustang. Every bracket, every gusset, every addition ( even the great ones that we'd all like to see on the car ) adds weight. My conversation in both April and August of last year with Steve Ling, Marketing Manager for Ford North America, indicated to me that at that time an IRS was not a dead certain "given", because of weight factors. Perhaps they can find ways and new technology in body panels and parts, to save enough weight to offset the IRS, but I walked away from the conversations with a feeling that an IRS in the next gen Mustang, was at best a 50 - 50 proposition.
