Con: M50 underdelivers on range and efficiency The i4 M50 I drove had the available 20-inch wheels, with corresponding M wheels, M Sport brakes, and Shadowline trim and lighting. The stance of the i4 with this combination is fantastic, but the wheels cost more than the $2,500 up front. Ride quality isn’t the same with them, and you take a huge dip in range by selecting them over the 19-inch wheels that otherwise come with the M50. The official EPA range of the M50 drops from 269 miles with the 19-inch wheels, and down to 227 miles with the 20-inch wheels this test car had. That’s already a dip from the 301 miles the eDrive40 version can extract from the same 80.7-kwh usable battery capacity. 2023 BMW i4 eDrive40 Note that much of the 2025 BMW i4 lineup does get a modest range boost, plus a refreshed look inside. Over the 336 miles I drove the i4, it averaged 2.6 miles per kwh, according to its trip computer, over a highway-focused mix, with ambient temps in the range of 55 degrees and the climate control set on auto to 69-72 degrees. While the eDrive40 seemed to overdeliver on its range, I quickly found 227 miles to be optimistic for the M50 in real-world conditions. I’m quite sure the Polestar 2 with the Performance package beats it in real-world driving, as it does by its 247-mile EPA rating. 2024 BMW i4 M50
