Range is expected to increase by less than 50 percent, falling short of 200 miles in the US market.

BMW's struggling i3 could be due for yet another upgrade after receiving a larger battery this year, potentially adding even more range and a fresh new look.

The i3's controversial styling will be revised with new front and rear fascias, unnamed sources recently told Welt am Sonntag.

This year's update simply swapped the original 22-kWh battery for a 33-kWh pack, increasing the EV's EPA-rated range to 114 miles from 81 miles. The next battery is said to stretch its range by less than 50 percent, potentially breaking the 150-mile threshold but short of the 200-mile benchmark shared by the Chevrolet Bolt and Tesla Model 3.

Despite offering a significant range increase, the urban EV and its range-extended sibling are experiencing a sales decline this year as deliveries slide by 30 percent in the US market. The trend suggests range alone was not the only issue holding back demand.

The Welt report seems to reference a mid-cycle update next year. A BMW executive recently confirmed plans to build a second-generation i3, but without pinning down a launch window.
