Spy photographers hit the jackpot recently when they spied a 2015 Ford Mustang test mule roaming in the wild. What looks like a 2013 Mustang test mule is actually a 2015 Mustang prototype with the much rumored Independent Rear Suspension (IRS).
The next generation Mustang will debut in early 2014 as a 2015 model with significant changes over the previous model including what many believe will be an independent rear suspension. Ford intends to make the 2015 Mustang a global vehicle and to do that they would almost certainly have to utilize an IRS setup to compete with European automakers.It only makes sense Ford would be out testing and tuning the new suspension to lock in the specs so they can concentrate on other areas as the debut draws closer.
The 2015 Mustang is also expected to be lighter, smaller in size and offer an EcoBoost four-cylinder engine similar in horsepower and performance to the current V6 engine. The 3.7-liter V6 and 5.0-liter V8 engines will also be available in 2015.
