2015 Mustang to Gain Weight?

[Moby Vic]

Steeda says so:
http://www.autoweek.com/article/2014...NEWS/140609982

Mustang tuner Steeda made headlines last weekend when it knocked the Blue Oval for adding 200-300 pounds to the 2015 Ford Mustang coupe. Steeda, like many tuners, gets a first look at these cars in order to properly prepare for the aftermarket.
“Our work is cut out for us because unbeknown to most Mustang aficionados (and not ‘officially’ confirmed by Ford for obvious reasons), the 2015 Mustang ended up gaining 200-300 pounds in this remake -- and with weight being the ‘enemy of performance,’ there are plenty of challenges needed to ensure that the 2015 iteration of America’s favorite ponycar isn’t left at the starting line spinning its wheels against the competition,” said Steeda’s blog.
The three variations of the 2015 Mustang come with either 300, 305 or 420 hp and 270, 300 or 390 lb-ft of torque. The previous 5.0-liter GT had a power-to-weight ratio of 8.61 pounds per horse, as opposed to the Camaro’s 9.17 and the Challenger SRT8 at 9.05. Gaining 250 pounds would put the 2015 Mustang’s curb weight at about 3,868 pounds, which would worsen its power to weight to 9.21. It could go from feeling the quickest of the ponycars to feeling the slowest. Sure, we’re only talking about a few pounds (per horse) here, but still.
Those of us who bought the 2014 model (ahem, yours truly) are feeling a little vindicated today. We’ve contacted Ford and are waiting for a comment.

I'm sure traditionalists will blame it all on the independent rear suspension.

Dumb article... they're comparing the rumored weight with the current hp rating (420hp) chances are it won't have 420 hp on release.

Challenger is 4170lb = 1891kg (+ 250 kg over Mustang)
Camaro is 3935lb = 1784kg (+ 143 kg over Mustang)
Mustang is 3618lb = 1641kg

There is room there for some weight gain, I'm sure everyone would prefer not to have the increase in weight but is that really realistic.

I will laugh if it hasn't gained at least 200 pounds, Steeda will looks like knobs.

[XWGT]

Hang on I thought Ford had already stated the car was going to be substantially LGHTER.
coming in around the 1400kg mark?

Big turn around

[Polyal]

1400 would be a minor miracle, the IRS would add a little but they may have used aluminum in the front end perhaps?

Id bet on a very very small increase.

[cheap]

A 1400kg Mustang? The MacLaren P1 sits at 1490kg. An old XW GT is 1500kg with non of today's weight contributing safety and comfort features.

[XWGT]

I hear you both but I'm sure that was what was put around at the Australian launch.

Substantially lighter

[Wretched]

Some more info from road and track.

While Autoblog and Steeda Auto claim the car will gain some 300 lbs, an insider familiar with the project has confirmed that that number is an exaggeration. The Mustang GT Premium, the heaviest possible trim package, will top out at roughly 250 lbs heavier than the 2014 car.

Volume models equipped with a V6 or the EcoBoost turbocharged four-cylinder engine are likely to be around 50 to 70 lbs heavier than this year’s model, while a base GT will gain around 170 lbs

Sounds a little more realistic but I would rather weight () until launch date.

[Bent8]

The word is the new 5.0 will be using some BOSS 302 bits to up the power and all they really need is an extra 10hp for every 100 pounds (45kg) and it won't effect power/weight ratios on paper..

Factory BOSS 302's are running mid 12's down the quarter so I think performance will still be mind blowing.

A BMW 428i sits at 1470kg as an automatic or 1450kg as a manual.
The 435i is 1525kg and 1510kg respectively.

The 4 series is a similar sized car and has IRS yet it maintains a 'low' weight.

Um, the Beemer has a 3-Litre straight 6 vs the Mustang's DOHC 5.0.. not really a fair comparison.

How 'bout the E92 M3 which weighs in at 1655kg with it's tiny 4L V8 ?.....

[Guzz226]

wasn't the description "smaller" used as part of the weight conversations around the new model.

ie making it slightly smaller to save weight or I guess offset weight gains in other areas eg IRS?

[hedgehobb]

Well, it is American.

[Bossxr8]

Alloy bonnet and fenders isn't it?

And it's a bit smaller too.

But all the early talk was of a weight loss of at least 100 pounds. But adding IRS and whatever else, you would think it would result in a weight gain. I guess we will wait and see what the official figures say.

Be careful with Euro weight claims, they're often measured based on the base spec for the U.K. market which is notorious for having very few options included. I've seen measured weights being up too 220 kg's heavier for various Euro models when fuelled and put on a weighbridge by well respected Autocar N.Z. After some of the disparities i've seen i take claimed weight with a grain of salt...but yeah, talk of a significant weight gain with the new Mustang is really off-putting when the earlier talk was was of significant weight loss. I'm looking forward to seeing the measured weight of the Ecoboost version.

[1TUFFUTE]

Yes I too was of the opinion early on that the new stang was considerably lighter
Interesting where all that came from

Ford said the car would be a little smaller than the current generation, and the press and Internet rumor mill proclaimed it would be lighter. Ford hasn't said anything official.

Ford hasn't released any weights, measures, or power output officially.

The increased weight rumor was criticized, but now Jalopnik says Road & Track says it will be heavier:

It will be lighter than a Camaro and substantially lighter than a Challenger no matter what.

I can put up with a bit of weight gain, the awful export version clear tail-lights are a totally different matter..

They'll be big in Japan.

They certainly have implied it though. Their response to not revealing the power figures for the V8 was that it would be around the current mark but would result in increased performance. If the engine is only going to out put 10 or so more kw how will it substantially improve performance if it gains weight rather than loses weight as was originally suggested?

[Polyal]

All depends on how you define performance.

I could not imagine that it would go backwards, not a chance actually, they are pushing it pretty hard.

The 2015 Mustang will have EcoBoost 4 cylinder, a 3.5L all alloy V6 and the Coyote V8. The literature suggests that even the lightest Ecoboost spec will be heavier than the previous lightest model (V6 Coupe?).

Those 4 series weights are the Australian specification kerb weights and given it's a requirement to have correct kerb weight for registration weight category, I have no reason to doubt them.

Ok so that tuner didnt even weigh the car, just based on a guess by older mustangs having IRS and being heavier..

So the car being heavier was nothing but a rumour based on someone taking a guess because it had IRS. however it has been said several times that weight loss could be anywhere from 100 to 400lbs.

nothing to panic over until official figures are released

We don't know for a fact that it has gained weight. And we don't know how much power it will make.

We do know that it should have much better ride than the current model. The world screamed for independent rear suspension in the Mustang. That adds weight.

[Polyal]

^^Would have been nice if it was an option to have the live axle still.

Yes, the drag racers like it.

The world press and Internet would have never forgiven it. They've been flogging Ford for not switching to IRS in 2005.

[Polyal]

True, but they could have just carried over the parts from the last model more or less. You dont have to refine a system that people know is harsh to the nth degree.

Im sure there will be aftermarket peeps all over the conversion!

[XP6]

dont care cant afford one

[dead_man00124]

in regards to a solid axle, from what ive read they still made provision's for people to be able to fit there own, ill try and find a link to the article i read

From a septic tank forum...

[Bossxr8]

IIRC Ford Racing will be offering a live axle kit.
