2015 Jeep Renegade Trailhawk: Fuel Economy Update for September - What's Behind Our Low MPG?

by Jonathan Elfalan, Road Test Editor on October 12, 2015

2015 Jeep Renegade Trailhawk

Last month, our recent-arrival 2015 Jeep Renegade Trailhawk returned some relatively unimpressive fuel economy figures. While we've yet to set it loose on freer pastures, we're still achieving only the estimated city economy numbers (21 mpg) about 40 percent of the time at best.

Some recent developments, however, could absolve our Renegade's 2.4-liter MultiAir engine of blame for our low efficiency.

There were a few issues we encountered over the past month, one involving a key fob malfunction that sent Monticello down memory lane, and another that inspired Dan Edmunds to coin the term "The Renegade Rumble." The latter, though fun to say, might be the culprit to our MPG woes. If Dan's supposition is correct and we're experiencing some type of differential malfunction, the elevated levels of driveline drag — imagine yourself running in sand — could be what's fueling our Renegade's increased thirst.

With a new lifetime average MPG of 20.4, we're at least moving in the right direction with an improvement of three-tenths over last month's figure. We have plans for both an extended road trip and investigating the mysterious rumble in the coming weeks, which should provide us more definitive answers.

In the meantime, we'll keep finding excuses to use "Renegade Rumble" in casual conversation.

Average Lifetime MPG: 20.4
