Ford Mustang enthusiasts rejoiced when they first learned that the all-new sixth-generation model would feature a fully independent rear suspension (IRS) and the option of a turbocharged 2.3-liter EcoBoost four-cylinder in addition to its naturally aspirated 3.7-liter V6 and 5.0-liter V8 offerings. Yet some of that excitement has been suppressed with a growing concern about the upcoming coupe's curb weight - Ford has released plenty of information about the vehicle, but it has kept absolutely silent about its mass.

After many of us speculated that the new model would shed some weight, after all, we all know that excess poundage is the enemy of performance and "lightweighting" is the engineering buzzword of the moment. However, our story last week contradicted that logic when Steeda Autosports, a company that has been given early access to the new model, stated on its website that "the 2015 Mustang ended up gaining 200-300 pounds in this remake." The report had enthusiasts audibly squirming in pain.

But it now appears that Steeda's statements may have been anything but scientific. The company, seemingly in a backpedal, clarified itself on Mustang6g.com today, saying: "Based on our experience working with IRS Mustangs in the past we estimated what the weight addition will be. In addition current industry trends with new cars show additional weight being added for various new safety and comfort features."

Steeda Autosport's well-publicized guess, as frustrating as it is, doesn't bother us as much as the Blue Oval's silence on the matter – is the automaker holding off on releasing bad news, or is it planning a pleasant surprise? We have tried contacting numerous sources at the automaker, and for the moment, mum's the word.

As it stands today, only one company knows the true curb weight of the sixth-generation model. So Ford, how much does the 2015 Mustang weigh?

      Patience is a virtue. I'm not going to get hot and bothered over some unsubstantiated claims, and Ford will eventually have to state the official numbers.

        Jalopnik seems to think that this is a calculated move by Ford to slowly release the weight numbers through media outlets before finally coming out and stating that the Mustang had indeed gained weight, but not as much as 200 - 300lbs. At this point, I'm just going to wait. If the weight gain is, say, 100lbs or so, then I'll still be disappointed but I'm not going to give up on the Mustang GT over that. I'll just be waiting until the 2017 - 2018 model year (as planned) and reading reviews from publications and owners alike in the mean time.

      Now I'm thoroughly amused by all the "matter of fact" comment posters on the previous thread about this.Guess it was all just a guess!

      The Steeda blog post was a PR attempt gone wrong. That said, they should have said that it was an estimate on their part and it would saved everyone time. I also think making that guess based on the IRS Cobras was a dumb idea, seeing as they have about as much in common with S550 as I do with Michael Schumacher.

        Even if they had said it was only an estimate on their part, many of those same folks would have still jumped to conclusions about the new Mustang's weight.

      The new Corvette is heavier. Weight is the enemy, but judicious application where necessary can yield a positive reward by virtue of additional chassis stiffness and vehicle balance. My car weighs right at 3000 pounds but would might perform better if anothe 100 pounds of metal was added to enhance chassis stiffness. Chassis stiffness allows the suspension and dynamic weight transfer to be much more predictable and provides for more accurate control of suspension with minimal deflection of "rigid" elements.

      To be honest, having an additional 200 lbs, if true, may not be that big of a deal. It's like adding a passenger to the vehicle, so the perception will not change. Also, it may benefit, if the weight is low and toward the rear of the vehicle, because it could give added traction during a drag launch. The independent rear suspension will also help with launching, because the bouncing of one tire will not affect the opposite side as drastically, providing more constant downforce. All in all, the weight gain could, conceivably, improve drag strip performance.

      Even if it did gain weight, it wouldn't exactly stop me in my tracks from considering one. For the majority, the weight penalty only makes a difference with MPGs; most people aren't exactly taking it to the track on the weekends. The frontend looks would give me more pause than the weight gain.

        Idk about the majority cares for weight for the mpg. Enthusiasts which are going to buy the new stand much more then family sedans are very interested in weight loss because of driving dynamics of the car. Even in canyon carving, weight is very important. The reason I see many people take the current gen stang over the camaro is weight.

      To be clear, it was posted by a member named "Seth @Steeda". I don't know if this guy actually works at Steeda.

        A user by his name is active on a couple of the Mustang forums I belong to. I assumed he was legit, but now I'm sure if he's legit, or an idiot. Maybe both? Either way, if it ends up being the car didn't gain the weight they are stated it had, Steeda is going to look pretty foolish.

      Honestly I don't see why anyone cares about this. The outgoing Mustang GT weighs 3,600lbs which is already massive. Let the Mustang be a direct competitor to the Challenger, and the Camaro will be in a class of its own.

        Wait what? If a 3600 lbs Mustang is "massive" then what is the Camaro? You do realize that the 2014 Camaro 1SS and 2SS tips the scale at over 3900 lbs right? So even if the GT gains 200-300 lbs it'll be lighter or on par with the Camaro. I'm not bashing on the Camaro, it's a great car (their ZL1 is amazing). But your logic makes zero sense. While Ford's been tight lipped on specs, they haven't been shy about boasting that the Performance Pack equipped 2015 Mustang GT is faster around Laguna Seca then the 2013 Boss 302 Laguna Seca. Weight will be the least of anyone's worries if this claim holds true.

          It took them 3 tries and 75k to beat the current Mustang but keep on waiting on that next gen.

      So basically it's not worth having everyone claiming our fake plans and aspirations have changed because OMG the curb weight might have gone up, maybe, we don't know.

        Could be. Personally, I didn't change my plans - real or otherwise. If I were intending to, say, replace my 15 year old Mustang GT convertible with a new one in about a year's time, I'd probably still be inclined to do so. That said, if the car does wind up weighing noticeably more than the S197 does, I'd be amongst those that were still sort of disappointed. But I'd still buy the car.

      I bet you it will still be lighter than the Camaro....

      Lets speculate, as per internet rules all speculations will be considered fact until official weight is released!
