Range Mode?

From the Owners Manual:
Range Mode: If on, Model S conserves energy by limiting the power of the climate control system. Cabin heating and cooling may be less effective, but seat heaters turn on to compensate.

I haven't noticed any change in performance in range mode so I think it's a climate limiting feature only.
 
A bit of conjecture: Additional to reducing HVAC power, in P85D & P90D vehicles, Range mode would seem to further bias power to the front motor using Torque Sleep, at least more so than with Range mode off.


From Driving Range for the Model S Family

Q: Which drive unit is able to sleep, front or rear?

With the P85D we put the large, rear, drive unit to sleep while cruising. We choose to sleep the rear unit since the new generation small front drive unit is actually more efficient at converting battery DC electricity into mechanical shaft power. So we benefit from using the small, front drive unit more of the time when it can provide all of the torque requested. In the 85D both drive units are the same and we can sleep either unit, front or rear to best optimize efficiency.
