Cadillac Lyriq
Charging curve · consumption · motorway range
The Cadillac Lyriq has 102 kWh of usable battery and peaks at 190 kW on a DC charger. In this app's model it uses about 216 Wh/km at a steady 100 km/h and 311 Wh/km at 130, so 44% more energy per kilometre buys you 30 km/h more speed. Weigh that against a 39-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 190 kW, but it has halved by about 61% 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% | 39 min | 71.4 kWh | 111 kW |
| 20% to 80% | 36 min | 61.2 kWh | 103 kW |
| 10% to 60% | 21 min | 51.0 kWh | 144 kW |
| 20% to 70% | 25 min | 51.0 kWh | 121 kW |
| 80% to 100% | 50 min | 20.4 kWh | 25 kW |

Consumption and range by cruise speed
Steady motorway cruising on flat road in mild weather, from the fitted model Wh/km = 78 + 0.0138 · 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 | 190 Wh/km | 537 km | 484 km |
| 100 km/h | 216 Wh/km | 472 km | 425 km |
| 110 km/h | 245 Wh/km | 416 km | 375 km |
| 120 km/h | 277 Wh/km | 369 km | 332 km |
| 130 km/h | 311 Wh/km | 328 km | 295 km |
| 140 km/h | 348 Wh/km | 293 km | 263 km |
| 150 km/h | 389 Wh/km | 263 km | 236 km |
| 160 km/h | 431 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
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 2024 Lyriq RWD on GM's Ultium pack: a 190 kW peak on a 102 kWh pack, so it gains SoC slowly in percentage terms.
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.
