In past testing, we found no fuel economy benefit using Eco mode for city driving. That proved to be the case again in our more recent tests.
That's the way I see it. To each his/her own. Forget ECON mode unless you want to play around. Your choice. Been there, done that.We measure highway fuel economy during steady cruising at 65 mph. This is an idealized driving scenario, with the transmission in its tallest gear, known as an overdrive for having a ratio of less than 1:1. We run this test in two directions to account for any potential impact of wind and terrain.
In this evaluation, Eco mode had no measured benefit. And that isn’t surprising: Acceleration and gear selection aren’t factors when holding a consistent speed on level ground.
