BMW updates plug-in hybrids with more range

The revised PHEV powertrains will arrive on the 2-, 3-, 5-, and 7-Series, along with the X5.

BMW is preparing to roll out new battery technology for many of its plug-in hybrid vehicles.

The improved high-voltage batteries are said to increase efficiency while boosting electric range, though the company has not announced how much more capacity has been added. The 530e and 745e can both run for up to 16 miles on electricity alone.

The latest tech will be available on the 330e, 530e, and 7 Series sedans, along with the 225xe Active Tourer and the X5 xDrive45e.

The PHEVs will also be equipped with "acoustic protection" technology to warn nearby pedestrians when the vehicle is operating in the quieter electric mode at low speeds.

Other changes include standard LED headlights for the X2 and new optional paint finishes, leather variants and interior trim elements for various models.

The updates are slated to arrive sometime this summer.
