General Motors EV1 - Technology and Design

Technology and Design

The decades before the release of the Impact and the EV1 had seen little in the way of development on the electric car front. The Henney Kilowatt, which ended production in 1961, was the last time a feasible production electric car of any sort had been released; GM's own Electrovair and Electrovette of 1966 and 1976, respectively, never reached production, amounting to little more than conceptual electric conversion kits for the automaker's popular gasoline models. Technical and production costs difficulties were blamed.

In contrast to these cars, the EV1 was designed from the ground up to be an electric vehicle. It was not a conversion of an existing vehicle, nor did it share a drivetrain with another GM model, which contributed to its high development and production costs. The EV1 program was initially administered by a GM engineer named Kenneth Baker, who had been the lead on the Electrovette program in the 1970s.
