AWD functionality....front single axle driving if AWD is not needed?

On the 2024 F150 Lghtning Pro AWD does Rear drive motor not draw current if it is not needed at highway speeds?

Both motors are always engaged. You can pull up the image of how much power each is getting.

In my experience, at highway speeds, the front and rear motors always drive together at the same commanded torque.

Because there's no mechanical disconnect, the way they "freewheel" the front tires on the Mustang is to send just enough power to mitigate any drag they would generate if they weren't powered. But they have to be powered. If they're not powered, they're braking. I haven't seen this on the Lightning (I have the Lariat, but I would be surprised if it's different for the Pro).

They do generate different braking torques, though.

Thank you!

I was just wondering if there could be a range enhancement by Free Wheeling or not powering say the rear drive motor.

With permanent magnet motors front and rear you would need a clutch mechanism to declutch one of the motors. With induction motors you could have one not powered and not creating any drag, but there are other compromises with induction vs permanent magnet motors. I've seen some YouTube videos on the difference between the two and their advantages, but it has been a while.

Yep. Because of the permanent magnets there will always be eddy currents induced. Better to power the motor than to drag it around.
