Ford Mustang Mach-E
Charging curve · consumption · motorway range
The Ford Mustang Mach-E has 91 kWh of usable battery and peaks at 150 kW on a DC charger. In this app's model it uses about 200 Wh/km at a steady 100 km/h and 288 Wh/km at 130, so 44% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 44-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 150 kW, but it has halved by about 60% 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% | 44 min | 63.7 kWh | 87 kW |
| 20% to 80% | 40 min | 54.6 kWh | 81 kW |
| 10% to 60% | 24 min | 45.5 kWh | 113 kW |
| 20% to 70% | 29 min | 45.5 kWh | 94 kW |
| 80% to 100% | 56 min | 18.2 kWh | 20 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 72 + 0.0128 · 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 | 176 Wh/km | 518 km | 466 km |
| 100 km/h | 200 Wh/km | 455 km | 410 km |
| 110 km/h | 227 Wh/km | 401 km | 361 km |
| 120 km/h | 256 Wh/km | 355 km | 320 km |
| 130 km/h | 288 Wh/km | 316 km | 284 km |
| 140 km/h | 323 Wh/km | 282 km | 254 km |
| 150 km/h | 360 Wh/km | 253 km | 228 km |
| 160 km/h | 400 Wh/km | 228 km | 205 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
Approximated from published EPA figures and fast-charge tests. American cars are rated on the EPA cycle rather than WLTP, and the consumption fit here is a motorway fit, so it will not reproduce an EPA range figure — that is the point, since EPA combined understates a 120 km/h cruise badly. Fitted to the 2023 Extended Range RWD. A modest 150 kW peak that holds unusually flat, so it rewards longer stops than its rivals.
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.
