2016 BMW 340i: August Fuel Economy Update - Back in Balance

by Jonathan Elfalan, Senior Road Test Editor on September 16, 2016

2016 BMW 340i

Last month we reported a dip in average fuel economy for our 2016 BMW 340i, largely due to a string of tanks inefficiently drained in LA city traffic. We needed a good road trip to help bring things back into balance, which is exactly what Editor Sadlier provided this month with a comfy cruise to the Pacific Northwest.

The long highway stretches, combined with Sadlier's impressive display of restraint, netted us a record tank of 518.4 miles and 34.6 mpg, easily besting the EPA's 33-mpg highway estimate. An all-time monthly high of 27.7 mpg was enough to push our 340i's lifetime average back above 24 mpg, which is where it was before the early summer months.

Now that school's back in session, we could be facing another low-efficiency month with the increased traffic. That may be all the reason we need to leave town again.

Worst Fill MPG: 14.2
Best Fill MPG: 34.6
Average Lifetime MPG: 24.5
EPA MPG Rating: 26 Combined (22 City/33 Highway Combined)
Best Range: 518.4 miles
Current Odometer: 9,261 miles
