Yes. It is meaningless to know the Leaf has a 24 kWh battery and the Tesla has 40 kWh. Completely and utterly useless. Range is determined by engine, weight, aerodynamics, and, yes, battery. The Leaf could, hypothetically, weigh half as much as the Tesla Roadster S, have a better coefficient of friction, a smaller engine, and get BETTER range with a smaller battery. It's like telling people how big the gas tank is on a car. There's a hell of a lot more you need to know to figure out the range. To give an extreme example, just because my passenger van has a 30 gallon tank and my civic has a 11 gallon tank doesn't mean the van is going to win an endurance race. Edit: Another concrete example, the Volkswagen 1L. It has a 1.7 gallon gas tank and gets a 400 mile range. [1] Your average Toyota might have a 50 mile range on the same amount of gas.
