“The BEV variant has an estimated range of 70 mi (110 km) and a computed consumption of 1.34 kW⋅h/mi (25.2 mpg‑e). Although using the air conditioner was not expected to affect the range, using the heater was expected to reduce range by up to half. Based on the typical distance driven, it was assumed that only 20% of the battery state of charge would be used each day for most NGDVs; analysis of USPS mail carrier routes demonstrated the all-electric variant’s range could accommodate 95% of all routes.”
