Tesla Model Y
Charging curve · consumption · motorway range
We model 3 versions of the Tesla Model Y. The Model Y Performance 79 kWh has 79 kWh of usable battery and peaks at 250 kW on a DC charger. In this app's model it uses about 167 Wh/km at a steady 100 km/h and 241 Wh/km at 130, so 44% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 28-minute 10-80% charging stop and you have the whole question of how fast to drive.

Which version you have matters
These share a name and not much else that a trip planner cares about. Pack size sets how far you go between stops, and the curve sets how long each one takes.
| Version | Usable battery | Peak DC | 10-80% | At 130 km/h | Range at 130 |
|---|---|---|---|---|---|
| Model Y RWD (LFP 57.5 kWh) | 57.5 kWh | 170 kW | 24 min | 215 Wh/km | 267 km |
| Model Y Long Range AWD 75 kWh | 75 kWh | 250 kW | 27 min | 224 Wh/km | 335 km |
| Model Y Performance 79 kWh | 79 kWh | 250 kW | 28 min | 241 Wh/km | 328 km |
DC charging curve
Charging power against state of charge, on a charger fast enough not to be the limit. Peak power is 250 kW, but it has halved by about 49% state of charge. That is why a short stop low down the curve usually beats a long one near the top.

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 60 + 0.0107 · v² for the Model Y Performance 79 kWh. 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 | 147 Wh/km | 539 km | 485 km |
| 100 km/h | 167 Wh/km | 473 km | 426 km |
| 110 km/h | 189 Wh/km | 417 km | 375 km |
| 120 km/h | 214 Wh/km | 369 km | 332 km |
| 130 km/h | 241 Wh/km | 328 km | 295 km |
| 140 km/h | 270 Wh/km | 293 km | 264 km |

| 160 km/h | 334 Wh/km | 237 km | 213 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
The volume Model Y: LFP pack, flat mid-SoC curve, and the smallest battery of any Tesla here — it stops often. Curated from Fastned/InsideEVs tests.
Model 3 Long Range pack and curve in a taller body — same charging, noticeably more drag. Curated from Fastned/InsideEVs tests.
Curated from Fastned/InsideEVs tests of the 2023 Model Y Performance. Same 250 kW peak as the Long Range, but the wider tyres and lowered ride cost it noticeably more per km at 130.
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.
