faster takes more energy, period. any car can be crippled to merely look better at a higher speed while actually being more wasteful. |
Year and a half driving the same exact route, same time of day, roughly even the same traffic load. I get 31mpg highway at 60mph, 30mpg at 70, and 31mpg again at 80. It's repeatable, at least in my car.
