1966 GM Electrovair II Electric Car – GM Could Have Been The World Leader In Electric Car Technology

by Mike

In 1966 General Motors experimented with an electric car based on the 1966 Corvair called the Electrovair II. It was powered by a silver zinc battery pack located in the front and the rear producing 532 volts.

Silver zinc was chosen because it delivered high peak power but the batteries wore out after 100 recharges and were expensive. The batteries powered a 115 horsepower AC-Induction motor that produced about the same performance as a gas powered Corvair except that the range was only 40-80 miles. The top speed was 80 MPH.

The Electrovair II weighed 800 pounds more than a regular Corvair and there were gauges on the dashboard for monitoring volts and amps.

This was just an experiment but one has to wonder where would they be if GM had continued developing electric car technology since 1966?

With the advanced electric cars that Tesla has developed from scratch – imagine what GM could have done if they would have funded this development and stuck with it since 1966.

    My family had a Corvair growing up and that front trunk was massive, it needed a bit of weight up there too, so this is a good candidate for a EV. I bet it could travel farther than a modern GM volt. Lets see the Corvair turbine car.

  2. Is there a reason my article stopped at ” 115 horsepower AC-Induction motor that produced about the”
    Sounded like a very interesting article, but I won’t be paying $3/month anytime soon.

    Perhaps as a big business, GM did not feel comfortable stepping on another big business – the oil companies. Just a thought…

    • But the oil companies are much much bigger than the car companies.

      The US car companies have almost gone under at a time when the oil companies are setting all time record profits for any company in any industry.

      Seems to me the car companies lost sight of their purpose.

        I’m thinking about back then… Perhaps it was not a “voluntary” decision to cease research on electric powered cars. BTW, GM came back some 20 years later with an EV1 that, although much more successful than the Electrovair, met the same fate.

    GM don’t really innovate. Not the guys at the top. Maybe some engineers had some fun with this project….but at GM it never had a future. Much like the EV1 in the 1990s. They did it to pay lip service to California’s zero emissions regs while at the same time moving heaven and earth to get those regs overturned. Once that was done…….no more EV1.

    GM is your “Me, too” car maker.

    Tesla is showing what a company with vision can do…..and to some extent, so is Nissan with the LEAF. They were selling a pure EV 5 years ago.
