The electric vehicle was popular in the early 1900s, outselling gasoline cars between 1899-1900. However, they then declined as better roads connected cities requiring longer ranges, gasoline became cheaper, and Henry Ford's mass production made gasoline cars more affordable. Interest renewed in the 1960s/70s due to concerns over emissions and oil dependence. Companies like Battronic and Elcar produced electric trucks and passenger vehicles during this time, though electric cars then again faded from the market.
