Neither of those cars get 150 miles of range. They're both squarely in the under-100 miles category. The BMW only reaches 150 if you get the "range extender," i.e. a motorcycle engine in the trunk that charges the battery. The MB has a "extended charge" mode where you get get a little over a 100 miles, at the expense of using some of the battery overprovisioning. Also, humorously, that Mercedes B-Class you linked to is, under the body, a Tesla frame and propulsion system. They're buying from Tesla because they don't have their own technology yet. Tesla only sells them 30-something kilowatt battery packs, though.
