The latest to criticize is Bill Ford, who takes issue not only with the General Motors-approved 230 figure, but also Nissan’s claim that its Leaf EV will get 367 mpg. The real culprit here, Ford said, is the EPA’s methodology, which he argues is meaningless. “This question devolves into madness,” Ford reportedly told Green Car Advisor:

“The government will have to come up with a meaningful number for customers – a user-friendly label. And I think they will. I can’t dispute that number, but I’m not sure it’s relevant to the customer either.”
