2014 vs 2015 Mustang

2014 vs 2015 Mustang

Last Updated February 5, 2020 | Sam Padgett

The 2014 and the 2015 Mustangs span the gap from the fifth to the sixth generations, from S197 Mustangs to S550 Mustangs. These two generations of Mustangs, being the two newest, represent some of the most technologically advanced pony cars on the market today.

2015 is a very special year for the Mustang. Marking its 50th anniversary, the 2015 Mustang is the product of half a century of automotive innovation. Even though this means that the Mustang turned 50, it is by no means in the midst of a mid-life crisis. As is evident from these two Mustang models, the Mustang platform never plateaus. Just look at how much has changed from its beginnings.

2014 and 2015 Mustang Exterior Differences

The look of the Mustang changed rather significantly between these two generations. The differences between the two are more easily felt than described. Overall, the 2015 Mustang just seems more modern. While late-model Mustangs have been bridging the gaps between retro and contemporary styles, the 2015 model strikes a great balance between the two.

The 2014 Mustang has the same style as the latter half of the S197 Mustangs. Unlike the early S197 Mustangs from around 2005 to 2006, the 2014 model has a smaller grille. The contour of the hood around the grille is smooth as well. The also comes with the option of grille-mounted fog lights which no longer continue to be an option on later Mustangs. All in all, this Mustang retains the quintessential toughness of a pony car while continuing to look like an easily daily-able vehicle.

While it shares the same basic appearance as the 2014 Mustang, the 2015 Mustang has an overall sleeker look. There are more contours and lines sculpted into the body of the 2015 Mustang than there are on previous models. Its headlights wrap around onto the side of the vehicle and aren’t as recessed into the hood as they are on the 2014 model. Additionally, the fog lights are positioned below the headlights as opposed to being embedded into the grille. The hood also has two long ridges that run from the windshield down towards the front of the car. The 2015 Mustang, while still being completely identifiable as a Mustang, looks more like other sporty two-door coupes out on the market today.

The rear of the 2015 Mustang no longer features the scalloped taillights that were a mark of fifth-generation Mustangs. Instead, they have a design that features solid vertical bars of light. This is a relatively minor change, but it does mean that the taillights of the 2015 Mustang are considerably brighter.

2014 and 2015 Mustang Interior Differences

There are several changes made between the 2014 and the 2015 Mustangs. Overall, they capture the same general look, subtly tough and futuristic. The best way to quickly describe all of the changes made to the 2015 Mustang's interior is that its an amplified version of the 2014's. The lines around the central infotainment screen and no longer straight, and they instead bend around the touchscreen to make it almost seem like it is bulging out of the car.

The buttons on the central console were redesigned between these two Mustang years as well. On the 2014 Mustang, they are sleeker and lay flat to the console. The 2015 Mustang, however, has large, bulbous, buttons and dials that really pop.

An interesting change between the 2014 and the 2015 models was that the shapes of each of the AC vents are swapped. All of the rectangular vents on the 2014 model are replaced with circular ones on the 2015 Mustang, and similarly, the circular vents are replaced by rectangular ones.

2014 and 2015 Mustang Engines

The big powertrain difference between these two generations is the frequently discussed Ford EcoBoost engine. The 2015 Mustang has the option for the 2.3L EcoBoost inline 4 engine. The gist of why this engine is special is that it’s a small engine that effectively balances power and efficiency. Simply put, it’s a turbocharged direct-injection engine with variable valve timing that gives the Mustang the power it deserves all while slowly sipping gasoline. With only four cylinders, the EcoBoost engine can make 310 horsepower and 320 pound-feet of torque while maintaining an mpg of 22 in the city and 31 on the highway.

The 2014 Mustang does have some excellent engines under its belt as well. In particular, the massive 5.8-liter DOHC supercharged V8, which makes 662 horsepower and 631 pound-feet of torque. This engine is used on the 2014 Shelby GT500, which should come as no surprise as that trim level is intended to be the most powerful.

2014 and 2015 Mustang Trims

The most exciting individual Mustang between the 2014 and the 2015 Mustang is undoubtedly the 2014 Shelby GT500. With a 0-60 time of 3.5 seconds, an 11.6 second quarter-mile time at 125 mph, a top speed of over 200 mph and 662 horsepower at its disposal, the 2014 Shelby GT500 continues the tradition of being one of the most downright intimidating vehicles to wear the Mustang name.

The 2015 Mustang doesn't have any trim levels as wild as the Shelby GT500. The only real addition to the Mustang line-up this year was the inclusion of the EcoBoost and EcoBoost premium Mustang. For all intents and purposes, this is a slightly altered Mustang GT meant to show-off the new engine.

2014 and 2015 Mustang Dimensions

In terms of dimensions, the 2015 Mustang is a slightly flatter and wider vehicle. When compared to the 2014 model, it is roughly an inch shorter and an inch wider. One more noticeable difference between these two Mustangs is the increase of front and rear legroom on the 2015 models. While this does come at the expense of an inch less of headroom, the 2015 Mustang has two inches of extra front legroom and a bit less than an inch of extra leg space in the rear.

In the practice of saving the best (or most important) for last, a huge difference was made between the 2014 and the 2015 Mustang regarding their suspensions. Up until the 2014 Mustang, the rear suspension system was a solid rear axle. This was swapped for independent rear suspension (IRS) on the 2015 Mustang. Not only does this change the feel and performance of the Mustang significantly, but it stirred up a debate in the Mustang community. A quick summary of the differences between both forms of rear suspension is that a solid rear axle is more durable and excels in drag racing, while independent rear suspension provides a smoother ride and better handling. There is quite a bit more to it than that, and of course, you could dive deeper into the debate here. The long and short of it is, Mustangs after 2015 do feel quite different behind the wheel than previous models.

2014 vs 2015 Mustang

2015 was a big year for the Mustang. For its 50th anniversary, it unveiled an entirely new generation of Mustangs. This generational jump means that there was a slew of changes made from 2014 to the 2015 Mustang.
