Hyundai Ioniq 5 58kWh range under different conditions and battery health levels.
About these figures
- The manufacturer never published a usable battery capacity for this car, only a gross figure. The 54kWh used here is an estimate, so charging times and efficiency are approximate.
- Hyundai's published capacity is 58kWh gross.
Why real range is below the official figure
WLTP tests run in mild lab conditions at gentle speeds, so nearly every EV undershoots the sticker in real driving. For the Hyundai Ioniq 5 58kWh, a fair planning figure is about 204 miles, roughly 85% of the official 240. That works out at about 3.8 miles per kWh from the 54kWh usable battery.
- Motorway runs at 70mph cost the most: air resistance rises sharply with speed
- Winter takes 20 to 25% off: expect around 160 miles on a cold day with the heating on
- Gentle town driving can beat the realistic figure, sometimes even the WLTP one
How battery health changes the picture
Range fades slowly as the battery ages. At 90% battery health the realistic range drops to about 183 miles, which most owners barely notice day to day. At 70% health, the typical warranty threshold, it falls to about 143 miles.
If you are buying a used Hyundai Ioniq 5 58kWh, that spread is the reason to get the battery's actual state of health measured rather than guessing from the odometer. A specialist reads it directly from the car in under an hour.
