Normally, a battery with a bigger capacity occupies more space than one with lower figures, which usually means having to adjust physical designs to accommodate the larger packs. BMW, however, has managed the rare feat of cramming higher capacity batteries in the same amount of space. That's what the 2017 BMW i3 (94 Ah) boasts of. Don't let the rather unusual name fool you. The BMW i3 (94 Ah) takes all the great things about the previous BMW i3 and takes it further, literally, with a 94 Ah, 33 kWh battery, all the way up to a 114 mile range.
