For those that get the two motor option on the X.
Would you like to have the rear gear box set to current spec and then have the front gear box set to a higher gear ratio?
This way the front gear box could take over at 40mph+ or so---for sure as you hit 65-75. I "think" this would perform the same effect as an overdrive to get better range per charge and have the capability for a higher top speed than the lower ratio gear box.
All of this can be coordinated via the control systems.
Any Tesla people or transmission/gear box sme's out there that can comment?
