The Honda Ridgeline has been very popular, due to its somewhat groundbreaking design, as it has the perks of a truck combined with that of a sport utility vehicle. One thing that has not helped it endear itself to consumers, however, is its fuel economy. In fact, the EPA has stated that Honda Ridgeline gas mileage is only 15 miles per gallon in the city, and 20 miles per gallon on the highway. Keep in mind that this is even for a five speed, manual transmission version of the Ridgeline. The Ridgeline is a great vehicle, but you may find yourself at the pump more often than you’d like.
