2012 Honda CR-V computer, in
2012 Honda CR-V computer, in city driving, was always correct, according to manual calculation. Highway it always show 1 or even more mpg less. With higher speed computer was more pessimistic. But driving 55 mph mpg was correct. 2010 Prius always optimistic by 6-7%. I noticed, most incorrect, when driving in EV mode. Computer mpg going up much more than on scan gauge.
