Tesla Model X's higher EPA range and efficiency ratings were recently reflected on the EPA's official website, which allows us to take a look what changed.

The new Tesla's are considered 2021 model year.

  • energy consumption (including charging losses):
    • combined: 105 MPGe - 321 Wh/mi (200 Wh/km)
    • city: 109 MPGe - 309 Wh/mi (192 Wh/km)
    • highway: 101 MPGe - 334 Wh/mi (208 Wh/km)

2021 Tesla Model X Performance

There are two separate ratings for the Performance version - with 20" and 22" wheels.

The 20" version hasĀ 341 miles (549 km) of range - up 36 miles (58 km) or 11.8%, while the 22" gets "only" 300 miles (483 km) - up 28 miles (45 km) or 10.3%. As we can see, the bigger wheels eat more than a tenth of the potential range.

The energy consumption of 20" wheels is 97 MPGe - 347 Wh/mi (216 Wh/km) - 7.8% better than before. In the case of 22" wheels, it's 86 MPGe - 392 Wh/mi (244 Wh/km) - 8.9% better than before.
