Ioniq 9 winter range
In Canadian winter driving, expect a Hyundai Ioniq 9 RWD to cover roughly 469 km at 0°C and 350 km at −20°C, compared with 539 km rated.

Ioniq 9 range at 0°C
Around freezing, we estimate the Ioniq 9 keeps about 87% of its rated range. The Ioniq 9 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.
Ioniq 9 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 Ioniq 9 ranks #7 of 30 in our −20°C estimates.

| AWD | 515 km | 448 km | 335 km | 35% |

Ioniq 9 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 Ioniq 9 offers battery preconditioning, set your navigation to the charger so the battery warms on the way.
