2015 Hyundai Sonata: Fuel Economy Update for August - Many Miles Moves the Needle
by Dan Frio, Automotive Editor on September 28, 2015
We stretched the legs of our long-term 2015 Hyundai Sonata in August, adding about 3,000 miles to the odometer. A couple of long road trips comprised almost half of those miles, but we ranged pretty far afield even when staying local. Of the 11 times we filled the Sonata in August, five of those tanks covered 300 or more miles.
We also managed to set a new MPG record. Skilled hypermiler Phil Reed managed to eke out 189 miles on just 5.7 gallons during his trip across the desert to Las Vegas, yielded 33.4 mpg. Granted, that's a somewhat abbreviated tank — less than half of the Sonata's usual capability — but still indicative of what we can achieve with a light foot.
For August, the Sonata averaged 27.0 mpg, just one gallon short of its EPA combined rating. This relatively efficient month helped boost the Sonata's lifetime MPG to 25.9 (from 25.6), which is close enough to 26, and which is tolerably closer to the EPA's 28 mpg combined — but a still not-insignificant shortfall.
Worst Fill MPG: 16.2
Best Fill MPG: 33.4
Average Lifetime MPG: 25.9
EPA MPG Rating: 28 Combined (24 City/35 Highway)
Best Range: 429.8
Current Odometer: 15,580
