For 2021, the X5's xDrive50i model has been replaced by the plug-in hybrid xDrive45e. The new plug-in hybrid powertrain consists of a turbocharged 3.0-liter inline-six and an electric motor for a total output of 389 horsepower. A 24.0-kWh battery pack is said to provide up to 30 miles of electric-only driving range. The regular 40i models also receive some light electrification in the form of a 48-volt hybrid system.
