Future electric cars. Paper presented at the International Automotive Engineering Congress, Detroit, Michigan, January 13-17, 1969.

The adaption of battery-operated cars by the turn of the century could be a less costly control of automotive air pollution than the suppression of most of the emission from the internal combustion engine. To close the 30-years gap between quantity production of all-combustion and all-battery automobiles, a hybrid vehicle concept is described, whose power system consists of a small turbine, generator, electric motor and batteries.
