Exxon Cordoba Hydrid-Gas Electric Car Technology Brochure (1978)

As part of its advanced battery program in the 1970s, Exxon had developed electric motor technology to be used in a hybrid-gas electric vehicle. In 1978, the EEI automotive team created a brochure that showed off to automakers the hybrid prototype Exxon had built with its ACS technology: a Chrysler Cordoba, which got 27 miles per gallon. That was the mileage target that the Environmental Protection Agency required of vehicles by 1985.  

At the time, the American auto industry grappled with the tough new mileage standards they feared could make their gas guzzlers obsolete.

“Detroit, your future can be both as big and as small as America wants it to be,” the brochure’s cover read.

Toyota-Exxon Work Plan on Exxon’s ACS Technology for Hybrid Vehicles (1979)

In 1979, Toyota entered into a collaboration with Exxon to work together on the oil company’s novel gas-electric hybrid drive system. Pages of the work plan can be seen here.

In 1981 Exxon’s engineers delivered a hybrid gas-electric Toyota Cressida to Japan. It was outfitted with Exxon’s technology that enabled use of an AC (alternating current) motor in a hybrid—cheaper, smaller and more reliable than DC (direct current) motors.

The Electric Car and the Petrochemical Industry: Boon Or Bane? Treat or Threat? (1970)

In 1970, Victor Wouk, an independent scientist presented a paper at the Petroleum Chemical Industry conference in Tulsa, Okla. about the challenges and rewards of electric vehicles. The electric car could be “a treat that can be introduced via the bridge of the heat engine/battery hybrid vehicle over the next several decades. Everyone should be encouraged to promote the development of electric vehicles,” he concluded.

Wouk built a prototype1974 hybrid Buick Skylark that got 30 miles per gallon, double its regular mileage, and emitted 9 percent of the emissions a typical model did.

Richard H. Baker Deposition: FTC v. Exxon Corporation (1980)

Richard H. Baker was hired by Electric Vehicle Control Systems in November 1976 as a full-time consultant. Baker by then had developed an alternating current synthesizer, or ACS, which the company used in its hybrid gas-electric vehicle prototype in the late 1970s.

To commercialize Baker’s ACS technology, the company bought Reliance Electric in 1979. The Federal Trade Commission filed an anti-trust lawsuit against Exxon to block the acquisition of Reliance. 

In 1980, Baker was deposed in Washington D.C. as part of the FTC’s suit.
