Tesla Model X Consumption vs Speed

Similar to the post about Model S Consumption vs Speed, there is a lot of data from Model X owners driving around with ABRP active in their browsers and logged in with MyTesla.

This is data from 1.2 million driving points from 279 Model X vehicles covering 160 000 km (100 000 miles), and almost all data points are included and corrected for elevation changes:

The blue points are individual power consumption samples. The yellow points are the median power consumption for each speed (to remove outliers) and the red line is a fitted fourth-order polynomial model of power-vs-speed. At 30 m/s (approx. 110 km/h or 65 mph), the median consumed power for a Model X is about 25 kW.

The ABRP reference consumption from this data becomes:

  • Metric: 237 Wh/km at 110 km/h
  • Imperial: 367 Wh/mile at 65 mph

which is lower than the default settings in ABRP. Not that this is a complete mix of all factors such as different vehicles, wheels, temperatures, weather and so on.

For fun, we can compare Model S and Model X curves:

Model X consumption

We can see that at low speeds, for example 10 m/s (36 km/h or 22 mph) the power consumption for both vehicles is pretty similar at about 7-8 kW. At high speeds, though, the much worse aerodynamic drag of the Model X comes in to play with full force. At 40 m/s (145 km/h or 90 mph), the Model S consumes 36 kW (250 Wh/km or 402 Wh/mile) whereas Model X needs 45 kW (312 Wh/km or 503 Wh/mile) to maintain speed.

Note that you can easily convert from instantaneous power (in W) to energy-per-distance using the formula Energy-per-distance [Wh/distance] = Power [W] / speed [distance/h]

Like this kind of data? Contribute data from your car too by logging in to MyTesla in ABRP and allowing data to be shared.
