I think the performance, efficiency, and top speed improvements were bigger than many expected.
Questions have been asked about how they did it, without real answers (yet.)
Asking some pointed questions here in case we can someday get more info:
#1: What are the gear ratios of the front and rear gearboxes?
#2: What are the RPM ranges for the front and rear motors?
#3: What do the horsepower and torque graphs look like for both motors over the full speed range (0-155MPH) of the P85D?
#4: Is the 691hp figure just a sum of front & rear motor max HP at different RPMs, or is there actually a time when the car is producing the full 691hp at a specific speed?
#5: How long/far can the dual motor cars actually drive at 155MPH?
Are these assumptions correct?:
The rear motor has shorter gearing for better 0-60 acceleration, and the front motor has taller gearing for higher top speed and highway efficiency...?
There is no clutch/decouple device on either motor, so the rear motor is forced to "freewheel" past power red-line when the front motor is pulling for top speed...?
