While most people think of electric cars as a new phenomenon (or a very old one), BMW has been working on them since 1972.
To mark its fourth decade of producing zero-emissions vehicles, the German automaker brought some past models together for a group photo shoot.
The trip down memory lane revealed some pretty cool cars, but none that could be used for practical driving until just a few years ago.
The 1602 Electric was born in 1972, and was used at the Olympic Games in Munich. It had a top speed of 62 mph and took eight seconds to go from 0 to 31 mph. Its battery pack weighed nearly 800 pounds.
From 1987 to 1990, BMW worked on the 325iX. It was actually slower than the 1972 car, but its 93 mile range was a big step up.
The E1 and E2, from the early 1990s, were BMW's fastest electric cars yet. They were also by far the ugliest.
