Then there is the GE-100, produced in 1977 around the time of GE’s centennial anniversary. It was a four passenger compact electric vehicle that showcased GE technologies at the time: (even Lexan windows using the same material as the Apollo missions.)
Another hybrid test vehicle developed in 1982 came out of a partnership with Volkswagon Research and the U.S. Dept. of Energy. Creatively dubbed the Hybrid Test Vehicle, it is similar to today’s plug-in hybrid cars. It hit over 100 mpg. Then there was the Electric Test Vehicle-1, built in 1978. It was also a DoE joint project featuring GE technology and an automotive body design by Chrysler. Using commercial lead acid batteries and GE traction motor/drive and controls developments, ETV-1 was the first ground-up modern day electric vehicle design.
The ETX-1 pure electric car came out of another D.O.E. joint partnership and used a two-passenger Ford Mercury LN-7 model. Unlike previous attempts that used dc motor/generators, it used ac motors. The ETX-II followed a year later in 1984 and used a larger model Ford Aerostar van.
