Geo Storm EV Mule, The Chevrolet Volt’s Baby Daddy?

While on the Infiniti JX launch event, I met a gentleman who now works with Nissan, who had a number of interesting stories about his tenure at GM, and what it was like to work on the EV1 program, as well as the technology that he swears was the forerunner to the Chevrolet Volt. According to him, GM engineers in 1991 needed a way to keep the batteries in their GM Storm EV mules charged. A crude range extender was fashioned out of a Honda generator, which would kick in when the batteries dropped below a certain point. The Storm mules were gutted and filled with batteries and a generator and driven around during development. He swears that, with the number of EV1 and Impact (the original GM EV) people left kicking around for the Volt's development, the range extender idea must have lived on in someone's mind for a very long time, until it came time to put it in operation. I begged him to grant me an interview, or at least let me quote him, but he wouldn't indulge me. I was left wondering about the early days of the program, until I stumbled upon this article in the January 1992 edition of Motor Trend. The big difference here is that GM has ditched the range extender and worked out a proper 220V charging system (apparently that was an obstacle in the early days).  Note that the EV1 charging paddle is absent here, and it seems to use a very-1990s flashing LED charge port, similar to the L.A. Gear running shoes that were found to have mercury in them. Since there seems to be a fair amount of Storm love on TTAC these days, it's worth recognizing the irony of a largely forgotten car paving the way for perhaps the biggest automotive lightning rod since the Edsel.
