The 2024 Ford Mustang Mach-E received a handful of updates for the new model year, as Ford Authority covered back in April. Perhaps the most notable is the addition of a brand new e-motor, which was developed in-house by FoMoCo engineers and is present in all trim levels. The new e-motor weighs less than the outgoing unit and also helps deliver improved torque across the lineup, to boot. However, Ford didn’t give us too much information about the details pertaining to this new motor at that time.
In this new video, an associate of former Ford engineer, owner of engineering consulting firm Munro & Associates, Inc., and YouTuber Sandy Munro provides us with those details, however, which are quite interesting. The new e-motors replace the outgoing Borg Warner units, and the two are quite different in terms of the winding used, as well as where the connections are located. For example, the new Ford e-motor has four connections within each of the three phases, which enables a bit more current flow capability versus the pair on the older unit.
The stack length of the Ford e-motor is also greater, helping it produce more torque, as well as provide greater thermal capacity. This design also adds flexibility in terms of its ability to upgrade to 800 volts at some point, given what we’ve seen in Hyundai’s electric motors. Bringing the motor construction in-house also enables some more commonality between the Ford Mustang Mach-E and F-150 Lightning, which reduces complexity and cuts costs.
Back when the Ford Mustang Mach-E originally launched, Munro secured one and completely disassembled it, then provided a video outlining his thoughts on each individual part. At that time, he praised the front motor design – calling it “fantastic” – but also noted that the rear motor was a bit too complex for his tastes. Now, with the arrival of this new design, it seems as if Ford has made some improvements, regardless.
