The best example might be the 1960s BMW Isetta converted by 48-year-old architect Hans-Georg Herb from Erfurt, Germany. The car runs on a recycled Tesla battery pack with 240 miles of range. Herb says that since he got both the car and the battery pack used (and the car is tiny), it has a particularly low carbon footprint. With a 322-horsepower electric motor in a microcar, it could prove adept at scampering up the Alps.
Scamper indeed! I knew a guy 50 years ago who had a 300 HP Isetta . . . . but his was a tri-power Pontiac 389 shoehorned in the back!
