Kia EV6
Charging curve · consumption · motorway range
The Kia EV6 has 74 kWh of usable battery and peaks at 240 kW on a DC charger. In this app's model it uses about 179 Wh/km at a steady 100 km/h and 261 Wh/km at 130, so 46% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 19-minute 10-80% charging stop and you have the whole question of how fast to drive.

DC charging curve
Charging power against state of charge, on a charger fast enough not to be the limit. Peak power is 240 kW, but it has halved by about 67% state of charge. That is why a short stop low down the curve usually beats a long one near the top.
How long a stop takes
| Charge from | Time | Energy added | Average power |
|---|---|---|---|
| 10% to 80% | 19 min | 51.8 kWh | 162 kW |
| 20% to 80% | 17 min | 44.4 kWh | 154 kW |
| 10% to 60% | 10 min | 37.0 kWh | 220 kW |
| 20% to 70% | 12 min | 37.0 kWh | 189 kW |
| 80% to 100% | 32 min | 14.8 kWh | 28 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 60 + 0.0119 · v². The “usable range” column is the honest one for trip planning: it is 100% down to 10%, because nobody arrives on empty.
| Cruise speed | Consumption | Range (full pack) | Usable range (100 to 10%) |
|---|---|---|---|
| 90 km/h | 156 Wh/km | 473 km | 426 km |
| 100 km/h | 179 Wh/km | 413 km | 372 km |
| 110 km/h | 204 Wh/km | 363 km | 326 km |
| 120 km/h | 231 Wh/km | 320 km | 288 km |
| 130 km/h | 261 Wh/km | 283 km | 255 km |
| 140 km/h | 293 Wh/km | 252 km | 227 km |
| 150 km/h | 328 Wh/km | 226 km | 203 km |
| 160 km/h | 365 Wh/km | 203 km | 183 km |
What the model does not include
- Elevation. The trip planner does account for climbs and descents; the range figures on this page are flat-road, so an alpine route will come out worse than the table.
- Temperature. These are mild-weather numbers. Cold raises consumption and cuts the charging curve. The planner models both. The numbers on this page do not.
- Wind, rain, roof boxes, payload and tyre choice, all of which move real consumption more than most people expect.
- Charger-side limits. The charging times above assume the site can deliver whatever the car asks for. A 150 kW cabinet shared with the car next to you will not.
Where these numbers come from
Hyundai/Kia E-GMP 800 V platform — peak power held nearly flat to ~45-50% SoC, then a steep taper, so these cars want short stops taken low. Curated from Fastned model guides + P3 Charging Index style tests.
What speed should you actually drive?
It depends on your route, on where the fast chargers happen to be and how the legal limits fall. Plan the real trip and the simulator will sweep every cruise speed against this car's curves and tell you which one arrives first.
