It's interesting that it featured regenerative electric braking. Whilst regenerative braking is an old idea, I couldn't find an earlier example of this applied to electric regeneration. It seems the first mention of this in a car is 1967's AMC Amitron concept but this industrial use predates that by over a decade.
