Why is it the most environmentally friendly car when pure EVs are also practical and widely available. I fail to see how adding a fossil fuel burning motor, no matter how efficient, is anything other than worse for the environment.
Some batteries, like NCA, have worse emissions than others.
Also: the grid is mostly coal and nat. gas today. Case in point: the Hummer EV burns more fossil fuels on electricity because it weighs 4 tons.
EV doesn't make anything automatically more efficient. Only the smallest and lightest EVs, like the Leaf, have high environmental scores.
