One of the significant ways we differentiate and even fight about cars is engine type: 3-cyl, 4-cyl, rotary, I-6, V-6, I-5, V-8, V-10, turbo, NA, supercharged, boxer, flat, flat-plane crankshaft, diesel, etc.

Obviously we will continue to argue about FWD, RWD, AWD, and where the motor should go, how many doors it has, hatchback vs wagon vs SUV, color, power, and so on.

But what kinds of things will we use to pit electric vehicles against each other once they become the norm?
