When it was announced that the 2015 Ford Mustang would have independent rear suspension and a host of new safety features inside and out, it was widely expected that the S550 would weigh at least a little more than the S197 Mustang that is in showrooms today. Some people speculated that the next generation Mustang would have a curb weight closer to that of the current Chevrolet Camaro and when Steeda posted on their blog that the 2015 Mustang would weigh about 300 pounds more than comparable current models, it seemed that the new Mustang could actually challenge the Camaro in the weight category.
I doubted that the 2015 Ford Mustang would gain that much weight and according to the information from Mustang6g.com, I was right. The inclusion of the more modern independent rear suspension in tandem with a great many other new features inside and out did indeed add some weight, but nowhere near the amount that some people were expecting. Should these numbers prove to be official, the 2015 Mustang is still going to have a pretty strong advantage in power to weight ratio – even if the engines don’t get much of a bump in power over the 2014 model year.
Below is a comparison of the approximate curb weights for the 2015 Ford Mustang and the similar 2014 Mustang. The EcoBoost models are listed last because this is a new option for 2015.
V6 Manual Fastback – 3526
V6 Automatic Fastback – 3529
V6 Manual Convertible – 3642
V6 Automatic Convertible – 3654
V6 Manual Coupe – 3501

When comparing the curb weights of the 2014 and 2015 Mustang with the base V6, the differences are very slight. The manual transmission fastback gains just 25 pounds while the automatic transmission fastback gains only 6 pounds over the 2014 Coupe. In the new drop top models, those Mustangs fitted with the V6 and manual transmission gained 12 pounds while the automatic transmission convertibles went up a meager 2 pounds for the new model year.
The weight increases for the 2015 Ford Mustang GT relative to the 2014 models is a bit more significant, but the gap is still a far cry from the previously reported 300 pounds. The 2015 Mustang GT Fastback with the manual transmission is 86 pounds heavier than the 2014 Mustang GT Coupe with the same manual transmission. Swap to the automatic transmission, and the 2015 model is only 52 pounds heavier than the outgoing model. The 2015 Mustang GT Convertible with the manual transmission has the largest increase over the 2014 models, adding 90 pounds while the droptop GT with the automatic transmission gains just 60 pounds.
Again, these numbers aren’t official figures from Ford Motor Company, but the folks at Mustang6g.com haven’t been wrong with any of their leaked information thus far, so there is no reason to question these numbers. Provided that they are fully accurate, the company won’t need to add much power to afford the 2015 Mustang the same (if not better) power to weight ratio as the outgoing models…while also offering the lowest curb weights in the segment.
