It will go slightly further than previously expected, but overall it's an electron guzzler.

According to the fresh EPA range and energy efficiency rating, the 2021 BMW X5 xDrive45e will go up to 31 miles (50 km) in all-electric mode. That's one mile more than in the preliminary specs.

The EV range is one of the highest among PHEVs in the U.S., but the energy efficiency is not too high: 50 MPGe - 674 Wh/mi (419 Wh/km).

Moreover, outside of the EV range, efficiency in hybrid mode is comparable to the conventional X5:
