This rare original Corbin Motors Sparrow are treasure to come across. Corbin managed to crank out 289 Sparrows before closing shop. This is one of them -- one of 289 in this "Limited Edition Second Generation" body style. Its 20-kilowatt DC motor produced the equivalent of 25 hp. Most of its 1. 50-lb weight was due to crude lead-acid batteries -- this is primitive electric vehicle technology. the Windows ME of EVs. It takes 4-6 hours to charge at a 110-volt socket. Built by Mike Corbin of motorcycle seat fame. the Sparrow was meant to be the three-wheeled city runabout of the future -- driven by the sort of mid-90s optimism that envisioned us riding around in near-silent bubble cars. grinning with the reassurance that our transportation efficiency had been honed to a single-serving maximum. In 1996. attendees at the San Francisco Auto Show sure believed it. At that time. the only electric vehicle was the GM EV1; Toyota's newfangled Prius was a Japanese-only exotic upon which we could wistfully gaze from afar.
