Wow, $3,900!

Ford Performance Parts is proud to offer the Eluminator!!! This electric motor is from the 2021 Mustang Mach E GT.

Peak torque: 430Nm (317 lb/ft)
Max speed: 13,800rpm
Gear ratio: 9.05:1

That would make this the rear motor of the Mach E, which is apparently from BorgWarner. The drawings and gear ratio spec look like the entire rear drive unit, complete with integral reduction gearing and differential, although that torque and speed would be for the bare motor. Note the capped-off axle outputs on each end; this is a coaxial design - the hollow-shaft motor is on the axle line. It would make no sense to offer this as an engine or engine-and-transmission replacement; it would need a suitable subframe to mount it at the driven axle. If you locked out the differential and fed one output to a separate final drive, the gearing would be wildly wrong (assuming you're not going racing on the salt flats).

Munro did a teardown:
Ford Mach-E Rear Motor Teardown and Analysis
... but the Munro vehicle is an AWD, I think Select trim, but not a GT. I don't know if the GT has a different motor at the front, or at the rear, or just the same motors with different inverters or just programming tweaks, but it doesn't look quite like these renderings to me. Sandy was in a "Tesla good, Ford bad" mood that day and criticized essentially everything about the unit, other than the use of planetary reduction gears (the unit uses a compound planetary set), but it's likely a sound design and well constructed.

First task is to find what inverter to use with it.

The inverter is mounted right to the drive unit case in rear Mach-E units; it would logically be included with the drive unit, but it is explicitly not included and could not be at the listed US$3,900 price. There isn't even a connector to plug in a cable to an inverter in the stock unit, because prongs from the inverter insert into the motor housing as in a Leaf.

Rationally, Ford should offer an "open" (user programmable) version of the stock inverter for this application.

Ford has a walled garden, which means we'd need to rent a car and pulling the CAN logs. They could just provide the info...

My query:



The reply, which was pleasantly received within a day or two of my ask:.



It's a big company, set in its ways, so not a surprising, albeit still disappointing, response.

So, barring a turn on a dime, it looks like we're on our own.
