TorqueNews starts the review by saying the B-Class Electric Drive will hit the US as the "chief competitor to the radically new BMW i3". Then it turns sour, covering the low range, extra weight of the large battery pack, and poor aerodynamics.
Some interesting points, but overall fairly negative:

However, the B-Class boasts unimpressive efficiency ratings compared to other battery electric vehicles on the market. It can offer 87 miles of range, slightly more than the i3 and Nissan LEAF, and 104 miles with the optional range extender package that allows the occasional maximum charge. But this range is due to a very large battery and is held back by a recently announced EPA-rated efficiency of just 84 MPGe combined
The main culprit is weight. It is heavier because it is a legacy gasoline/diesel luxury vehicle constructed primarily of steel with the powertrain swapped out. In addition, the B-Class has a significantly larger battery than both the Nissan and BMW; it boasts 36 kWh of capacity compared with 22 kWh for the i3 and 24 kWh for the LEAF. The extra battery capacity adds significant weight. - See more at: http://www.torquenews.com/2250/why-mercedes-benz-b-class-electric-drive-has-only-87-mile-range#sthash.KrWhLy1h.dpuf
