i4 winter range

In Canadian winter driving, expect a BMW i4 eDrive40 (18-inch wheels) to cover roughly 466 km at 0°C and 348 km at −20°C, compared with 536 km rated.

i4 range at 0°C

Around freezing, we estimate the i4 keeps about 87% of its rated range. The i4 has a heat pump, which heats the cabin with far less energy than a resistive heater. That is the biggest single factor in cold-weather range.

i4 range at −20°C

At −20°C, battery chemistry slows and cabin heating runs hard, so we estimate about 65% of rated range. The best i4 ranks #9 of 30 in our −20°C estimates.

i4 range in cold weather in Canada

Most winter range loss is temporary: it returns when temperatures rise. Owners in Canada recover a good share of it by preheating the cabin and battery while still plugged in, using seat and steering wheel heaters instead of high cabin temperatures, parking in a garage when possible, and keeping tires at the recommended pressure, which drops as air cools.

Fast charging is also slower on a cold battery. If the i4 offers battery preconditioning, set your navigation to the charger so the battery warms on the way.
