The electric car world is moving apace, and so are the language and reference points we use. Not only is there range (still expressed in good old-fashioned miles), but also battery size (kWh). Then there’s efficiency (miles per kWh), charging speed (kW), and now also the consistency that speed is delivered. 

Most important at the dawn of the electric era was range, and to this day electric cars are largely marketed around that number.
