Research — Drivers should not rely too heavily on fuel economy displays
AAA photo
(July 29, 2021) In-dash fuel economy displays estimate the number of miles a vehicle gets per gallon, including how many “miles to empty.” AAA tested the accuracy of these systems and found their estimates vary significantly over shorter trips or are dependent on the consistency of things that affect gas mileage like speed and acceleration. This means drivers could be taking an unnecessary risk if they over rely on these displays.
