Midrange has regen braking on rear wheels only - says EPA

[eethan]

If you look at EPA spreadsheet > EVs tab > Column CY, it clearly shows:

- Regen braking wheels source: Midrange - Rear wheels, LR/AWD - Both

That explains why the MR City range is less than it should be:

MR Range: City (274.1) , Hwy (251.2) , City/Hwy = 274.1/251.2 = 1.0911
LR Range: City (345) , Hwy (311.7), City/Hwy = 1.1068

That means the MR must have battery capacity 66+ kWH to compensate for the loss in regen efficiency

Model 3 Mid Range has 251 miles highway range according to EPA - Teslike.com

I can guarantee you that the RWD LR Model 3 only has regen on the rear wheels as well...

Neither the MR nor RWD LR cars have a motor in the front to regen with, so that is a misprint

Then Tesla must have set the regen braking to be more conservative on the smaller MR battery to reduce stress across fewer cells. That would explain the slight drop in expected city range.

Or it was very minor and is just a rounding issue. Maybe the LR was 26.4 kWh/100 miles while the MR was 26.5 kWh/100 miles, so they rounded the LR down and the MR up and there really isn't much difference.

They meant to say LR AWD. Not LR and AWD.
