An official from Steeda has provided more details about the expected 200-300 lbs weight gain of the 2015 Ford Mustang.

Last weekend, Mustang parts manufacturer and seller Steeda mentioned in a blog post the all-new pony car has gained between 200 and 300 lbs (91 and 136 kg). However, that might not be the case as those numbers may not have been exact. They posted those figures by taking into consideration their experience with Mustangs fitted with an independent rear suspension. In addition, Steeda believes some of the added weight is also related to the new comfort and safety features of the Mustang.

On a related note, a Ford insider told Road & Track the new Mustang has gained weight but not as much as initially reported. He says the Mustang GT Premium, the heaviest version available, is going to be approximately 250 lbs (113 kg) heavier than the 2014MY. V6 and EcoBoost versions will allegedly end up between 50 and 70 lbs (23 and 31 kg) heavier, while the base GT will gain somewhere in the region of 170 lbs (77 kg).

R&T sources say the Shelby GT350 will likely be powered by a smaller naturally aspirated engine to offset the added weight. To minimize the weight gain, the car could end up boasting a small amount of carbon fiber in its construction.
