I have an upcoming cross-country drive...
Do you think "turning off" one of the motors (i.e. 100% FWD or RWD) would increase efficiency?
That's already being done automatically, unless you accelerate or brake hard.
Based on my Scan My Tesla data (app that reads directly from the CAN bus), the front motor is rarely used while just cruising around.
Which makes sense as the front motor (AC induction) is less efficient than the rear motor (permanent magnet).
BTW my 19x9.5" lightweight wheels, RE71R tires, brake pads, and high-temp brake fluid cost less than half of the new "track package" offered by Tesla.
For the $5,500 they're asking, I was able to also buy slotted/drilled rotors, stainless steel brake lines, AND sway bars to fix that nasty body roll.
Another $2,500 for coilovers, and my car is much more track worthy than it would ever be with that track package.
Separately, I can't wait for Track Mode v2! Any idea what firmware version that will be included in?
