But vehicles default to a fuel-saving mode at — like the 2014 Jeep Cherokee — set economy as the “predominant” from which the EPA bases its the agency told .

If a car has system that stays in you last drove, the EPA may not be able to a “predominant” mode. In such “the vehicle is tested in the modes and the fuel economy from the best and worst are harmonically averaged,” EPA officials “For example, if a vehicle has a mode, normal mode, and mode, the fuel economy of the sport and economy modes be averaged.”

Automakers can (and often do) customer surveys or technical that show that use one particular mode most of the — so if Honda determined that 80% of owners drove everywhere in mode, then it could that the EPA rerate the Civic economy-mode driving.
