That's an argument I've seen repeated over and over again, but it's flawed. Electric motors are superior to internal combustion engines in pretty much everything. But that's looking at just one piece of the electric drivetrain, ignoring its Achilles' heel, energy storage. By contrast one can argue that internal combustion engine vehicles, while disappointing on the energy conversion side, balance that downside out with supremely efficient energy storage. Between inverters, charging module, power electronic, battery charge/discharge efficiency etc., electric vehicles do the opposite. Heck, high-voltage fast chargers need water cooled cables, so forget 98% efficiency... Add to that the issues of energy density and cost of batteries, and you can see why internal combustion engines still have a place.
