2015 Ford Mustang Eco Boost 4

Hypes: Eco Boost Motor is a Keeper, Stellar Exterior Redo
Gripes: Needs Rear Wiper, Closer 2nd-3rd Gear Ratios

Back in the first 1960s heyday of the Mustang, if you saw a button on the dash marked “Shaker” you knew that the ram intake on your hood would open when you pressed that magic button. More cold air meant more horsepower. Because the induction scoop was mounted on the engine and was not part of the hood, it would vibrate in synch with the engine, earning it the name Shaker. The 2015 Mustang has a “Shaker” button on the dash, but this one has nothing at all to do with increasing air intake. Rather, it refers to an optional $1,795 “Shaker Pro Audio System” which includes 12 speakers. The button simply enhances the rush of hot air through those dozen speakers, not the rush of cold air into your motor.

Once I got over the initial disappointment of that generational descriptive shift, I discovered that the latest Mustang has lost nothing of its rambunctious nature, active hood scoop or not. Our Ingot Silver Metallic test bullet fully lives up to the brand’s storied reputation. Without question, this is the best Mustang Ford has ever built. Three engine options are available this year, with the V6 model being the most affordable at a base price of $23,600. The subject of this test is the EcoBoost Premium Fastback, with a turbocharged 2.4 liter inline 4, and a Base Price of $29,300. The least expensive V8 Mustang is the GT Fastback, which carries a Base Price of $32,100. It’s been quite awhile since Ford sold a 4 cylinder Mustang, so we were curious to see whether such a fuel efficient power source (25 MPG Combined City/Highway) could cut it in the performance department. With its output of 310hp @ 5500rpm and 320lb.-ft. of torque @ 3000rpm, the answer is an unqualified yes. Even when coupled to the 6-speed “Select Shift” automatic transmission ($1,195), the turbo Mustang was always up to the task of rapid mobilization.

The Select Shift gearbox can be slotted into a Sport setting marked “S” on the floor console. Once you’ve selected that quadrant, the small paddle shifts behind the steering wheel can be used for all up and down gear changes. The only drawback to the automatic gearbox is its big gap between 2nd and 3rd gears. Most of the time, you will lose 1500rpm when shifting up, which puts the small displacement four banger at an acceleration disadvantage. I would much prefer to see these two most frequently used gear ratios closer together for back road work.

Other than that shortcoming, the turbo 4 Mustang runs back roads like a scalded snake. The optional “Eco Boost Performance Package” ($1,995) is a must if your drives have more curves than straights. Ford engineering’s absolute stroke of genius is to equip the Performance Package enhanced Mustang with whopping fat Pirelli P Zero tires (255/40ZR19) at each corner, mounted on tastefully understated Ebony Black Painted aluminum wheels. The final flourish to this bargain priced package is inclusion of a 3.55:1 Limited Slip rear axle that insures your Mustang instant forward bite when you tromp the throttle.

Almost every time I started the Mustang, I made sure to engage my “Drive Mode” of choice. This is accomplished by flipping a chrome plated switch on the lower face of the central console to the setting marked with a helmet for “Track.” This configures the suspension for sport driving and reallocates the shift points to maximize thrust. Next to that switch is an identical toggle for steering feedback, which I always set to “Sport.” With these preparations made, the Mustang hunkered down over its Pirellis and absolutely refused to slide or deviate in any way from my selected line through switchback turns.

On the window sticker, Ford identifies the Mustang as a “”4-Passenger Sports Car.” After spending a week behind the wheel, I would never quibble with that description, though I must admit to a preference for the front seat rather than the limited vision back seat. If you do carry passengers in back, you’ll want to provide them with air sickness bags because the latest Mustang is a true g-Force generator second to none.
