BMW may have launched its first electric car — the i3 — in 2013, but the Germans have been testing battery-powered vehicles since the late 1960s. The Bavarian automaker even went as far as to build two functional prototypes in the early 1970s, one of which was unveiled at the 1972 Olympic Games in Munich. Named the 1602e, BMW’s first EV was based on the 1602 version of the 02 Series that preceded the first-generation 3 Series. While the standard model was powered by a 1.6-liter, inline-four engine rated at 85 horsepower, the 1602e used an electric motor supplied by Bosch, and a dozen normal, 12-volt car batteries linked together into a cell. As you might imagine, performance was far from staggering.
