When it comes to EVs, efficiency is crucial since it dictates how much
power you'll "burn" when driving and how much you'll spend for it overall.
The Model Y may use anything from 26 to 30 kilowatt-hours every 100
miles travelled, depending on the powertrain, according to the EPA window sticker.
The most economical variant is the standard RWD model, which uses 26 kWh per 100 miles.
The AWD Long Range and AWD Performance use 28 and 30 kWh per 100 miles, respectively.
