Say it ain’t so! Independent car review tests performed by a major automotive publication seem to show the EcoBoost Mustang getting slower going from 0-60 and in the 1/4-mile! In acceleration tests performed by Motor Trend and reported on by Jalopnik, a 2016 Performance Pack Manual EcoBoost Mustang went from 0-60 .7 seconds slower and .4 seconds slowed in the 1/4-mile.
Understanding the Data
Over the past two years, Motor Trend has tested 4 EcoBoost Mustangs with these results.
- 2015 EcoBoost Automatic Perf. Pack: 0-60 in 5.6, quarter mile in 14.1
- 2015 EcoBoost Manual, no Perf. Pack: 0-60 in 5.6, quarter mile in 14.4
- 2015 EcoBoost Manual Perf. Pack: 0-60 in 6.0, quarter mile in 14.3 (Automobile test)
- 2016 EcoBoost Manual Perf. Pack: 0-60 in 6.3, quarter mile in 14.5
Just as a refresher, the Performance Pack included 3.55 limited-slip rear gears and summer tires, which should make for decent acceleration. But not according to these results.
The 2016 was by far the slowest yet, with the 6.3 0-60 time being a far cry from the mid to low 5 second 0-60 times that were being squeezed out in the beginning.
Eliminating Outside Factors
Motor Trend went into pretty granular details trying to figure out what was going on. The checked everything with the car and even things outside of it like weather conditions, ultimately reaching out to Ford for some answers.
From the Motor Trend article itself, they said the following:
“We reached out to Ford after our most recent test with all our data. A Ford communications representative noted that the quickest manual transmission Mustang EcoBoost we tested (the second car) was a pre-production model and speculated that it may have had a “different calibration.” He did not elaborate. He also speculated extremely hot weather could cause the computer to pull timing, but when presented with weather data showing the car was tested on a 55-degree day, he said “it should’ve been making great power.”
The only thing that stands out from this response is the possibility of having a ‘different calibration’ on the engine, something auto manufacturers are known to do from time to time.
Jalopnik.com also reached out to Ford to gain some insight on this issue and Ford responded saying:
The class-leading power and output of the Ford Mustang 2.3-liter EcoBoost haven’t changed since we launched the new car in 2014. It’s the same powertrain, calibration and gearing. Different drivers in different cars can have different test results, especially when driving manual transmissions. We are investigating MotorTrend’s results.
Why This Is Probably a Fluke
If you are an EcoBoost owner, by this point in the article you are probably feeling a little woozy after reading through all of this, going over in your head if you’ve noticed a difference in power or performance. Take a deep breathe, it’s going to be okay.
Finding discrepancies like these in vehicle performance stats is nothing new and somewhat of a common occurrence in the automotive journalism world. Similar to how there are factory freak cars that pump out well over what they should from the factory, there is also the inverse of that– cars that make a little below what they should from the factory.
If that isn’t enough to skew results towards the unfavorable, pair that with some poor shifting and questionable external conditions and you will find your loss of power.
Why This Ultimately Doesn’t Matter
The great thing about owning a Mustang, no matter what engine is under the hood, is having an ever-expanding aftermarket to help tweak and refine your ‘Stang t o the way you want it. For the sake of an argument, even if the EcoBoost Mustang is suffering from some minor power loss, it really doesn’t matter when you can just add a cold air intake and tuner and have more power, torque, and better fuel mileage than stock.
With the options and parts available to mod your Mustang with, you are never more than a purchase or two away from making a major acceleration, handling or braking difference on your pony. Power loss rumors aside, modding your Mustang is a great idea simply for wanting to get more out of your car, giving you greater enjoyment every time your hit the throttle.
What do you think? Is you EcoBoost feeling a little slower or are you still spinning tires without a problem?
