Mazda Motor Corp., running counter to the industry’s shift toward electric vehicles, says rapid improvements in conventional-engine technology mean non-gasoline cars won’t be needed on a mass scale to solve pollution woes. The automaker says electric cars may be more polluting than vehicles with internal combustion engines if the electric power isn’t from a clean source. It estimates the level of carbon dioxide emitted by a gasoline-engine Mazda2 at about 9 percent less than the 162 grams-per-kilometer attributed to an electric version of the car whose power comes from a coal-fired plant.
Fully replacing conventional cars with electric would require power output to double, Hitomi said, citing the carmaker’s own estimates. Costs would rise because the increase would be coming mainly from clean sources such as solar and wind, which are more expensive.
Electricity prices will also surge because drivers will typically be charging up at the same time of day, spiking peak demand, he said.
“Think about these negative consequences for consumers when you have more electric cars,” Hitomi said. “I personally don’t think the age for electric vehicles will ever come.”
