Price remains the biggest factor for car shoppers looking to buy an electric vehicle. Just behind that, though, is what kind of efficiency the EV gets — which is equivalent to the fuel economy of a gas-powered vehicle. The more efficient an EV is, the more range it gets out of its battery. It's like buying a gas car with a fuel economy of less than 30 miles per galloon, versus one that gets 40 mpg.
That’s why I’ve been testing the best electric cars for the past year, driving them for a week to uncover their average efficiency. For the most part, 3 miles per kilowatt-hour (3 mi/kWh) is what I’d consider average efficiency. However, there are several that I’ve tested that even manage to go beyond 4 mi/kWh.
