Ford Motor Company states it will get to the base of a report that purports?to exhibit?2.3-liter EcoBoost Mustangs getting slower in acceleration tests over time.
The 0C60 mile per hour times, recorded through?Motor Trend?throughout four separate automobile tests, show the widening acceleration space that left reviewers puzzled as to the cause.
Ford’s 2.3-liter EcoBoost four-cylinder, along with 310 horsepower and 330 pounds-feet of torque running on premium gas, powered each check vehicle. The first check, a 2015 model with an automatic transmission and Performance Package, recorded a 5.6 2nd run to 60 miles per hour?- the same time like a 2015 manual-transmission model with no Performance Package. (That upgrade adds a 3.55:1 back axle and 19-inch wheels shod with summer tires).
A test of the 2015 Ecoboost with manual transmission and Performance Package by Motor Trend’s sister publication Automobile noticed a 6.Zero second?0C60 run, and a similarly equipped 2016 model recorded an acceleration time of 6.3 seconds.
There are a number of culprits that could play a role in the mystery. The publication noted instances of throttle lag during particular upshifts on manual transmission models. As a result, “Getting a perfect run was very difficult and took several attempts.”
A Ford representative said the first Mustang tested was a pre-production model, adding (with no elaboration) that a “different calibration” could explain the quicker speed time. A theory that high temperatures hampered later tests didn’capital t pan out, because of the mild temperatures documented during testing.
In instructions to Jalopnik, Ford said the engine’s result hasn’t changed, and added that the organization was now looking into the results of the assessments. The automaker mentioned, “Different drivers in various cars can have various test results, especially when driving manual microbial infection.”
Is there anything to this particular, or is the slowing EcoBoost Mustang mystery only the result of normal testing variability? We’ll wait and see. In the meantime, there’utes no shortage of alternative Mustang engines with regard to concerned/paranoid would-be buyers.
