Toyota says no small, cheap EV is in the works Although many automakers, including VW, Stellantis, and Kia, have revealed plans to launch low-cost EVs under $30,000 (£25,000), Toyota says not so fast. Toyota’s European product development boss, Andrea Carlucci, told Autocar that battery costs make a cheap EV unlikely.
