DETROIT -- Adding independent rear suspension, numerous electronic safety features and other items raised the weight and lowered the fuel economy of several models of the rebuilt 2015 Ford Mustang, according to window stickers leaked on the Internet today.
Ford officials would not confirm the authenticity of the EPA numbers, which can be seen here: http://www.mustang6g.com/.
“We have not discussed fuel economy at all, and we’d like to wait until the EPA officially releases the Mustang’s fuel economy ratings,” said Ford spokesman Brian Cotter. He added that he could not confirm the EPA numbers on the window labels.
According to the leaked window labels, the 2015 Mustang V-6 automatic’s fuel economy falls from 31 on the highway for the 2014 model to 28 for the redesigned 2015, putting the Mustang 2 miles behind its rival, the Chevrolet Camaro V-6 automatic.
The manual transmission version of the 2015 Mustang V-6 also sees a decline, from 19 city, 29 highway and 22 combined for the 2014 to 17 city, 28 highway and 21 combined.
The 2.3-liter four-cylinder Mustang — new for 2015 — with a manual transmission appears to be the most fuel-efficient model, coming in at 22/31/26, according to the leaked window stickers.
The 2015 Mustang’s curb weight has increased on four of the six models. The new car is slightly larger than the outgoing model. Weights for the coupe range from 3,524 pounds for a four-cylinder automatic to 3,729 pounds for the V-8 automatic. The 2014 models ranged from 3,501 pounds for the V-6 manual coupe to 3,618 pounds for the V-8 automatic. Ford has not released curb weights or EPA mileage numbers for the convertibles.
Ford has struggled to meet its promise of reducing vehicle weight between 200 and 700 pounds with each redesign.
