2019 Tesla Model X EPA Ratings Compared: LR & Performance

The Long Range Tesla Model X can go up to 325 miles (523 km) on a single charge and uses 351 Wh/mi (218 Wh/km) including charging losses, according to the EPA.

Together with all versions of the Tesla Model S, the EPA updated the online range/energy consumption numbers for two new Tesla Model Xversions – the Long Range and Performance (with 22-inch wheels). The Standard Range and Performance with base 20-inch wheels are still missing.

The new naming scheme from Tesla of Standard/Long Range/Performance replaced the previous, related to battery capacity and powertrain (75D, 100D, P100D, etc.). The Long Range and Performance versions are still equipped with ≈100 kWh batteries, while Standard is ≈75 kWh.

According to the latest test results, the new Long Range version (former 100D) is able to go 10% further on a single charge: 325 miles (523 km)compared to 295 miles (475 km). The higher result was achieved by corresponding improved efficiency of the latest S/X cars. The energy consumption in the combined cycle decreased to 351 Wh/mi (218 Wh/km), including charging losses.

Interestingly, the top of the line Performance version with the 22-inch wheels (compared to 20-inch standard) is way less efficient. Range is just 270 miles (434 km) (down 17%!), while energy consumption 427 Wh/mi (265 Wh/km) (up 21.7%). It’s the price of more performance and the appearance of a car on bigger wheels.
