In the wake of the Hyundai/Kia mileage brouhaha—in which the South Korean automakers stated that “procedural errors” had led to inflated fuel-economy numbers for more than 70 of their 2011-13 models (read the story)—we decided to examine the mileage that we got on our 2011-13 test vehicles. We found that Hyundai and Kia were correct: Their original numbers were much higher than what we averaged on the highways and city streets in and around Chicago.

Even more notable is that Hyundai’s and Kia’s revised EPA numbers still seem too high. Of the 74 2011-13 models for which they revised their fuel-economy estimates, we (Consumer Guide Automotive editors) have test driven 17 of them over a minimum of 200 miles each. For 15 of the 17, our mileage was lower than their revised estimates. (Our fuel-economy numbers are based on the amount of fuel we purchase and the number of miles we drive.)

Skeptics will say that real-world mileage doesn’t always match the automakers’ sticker numbers. However, we looked at 50 2011-13 vehicles from Chevrolet, Ford, Honda, Nissan, and Toyota that we test drove. For 24 of those 50, our fuel-economy numbers were better than the EPA numbers (i.e., the numbers that the automakers report to the EPA).

Breaking it down:

Of the 17 2011-13 Hyundai/Kia cars and SUVs that we test drove, we exceeded the revised EPA combined number on 2 of the vehicles (12%). The average difference between our real-world number and the EPA number was -2.62 mpg, meaning that our 17 real-world numbers were, on average, 2.62 mpg worse than the revised EPA numbers. Incidentally, our mileage was, on average, 4.27 mpg worse than Hyundai/Kia’s original EPA numbers.

For 14 2011-13 Chevrolet cars and SUVS that we test drove, we exceeded the EPA numbers on 6 (43%). The average difference between our real-world number and the EPA number was -1.13 mpg, meaning that our 14 real-world numbers were, on average, 1.13 mpg worse than Chevrolet’s posted EPA numbers.

For Ford, we exceeded on 7 of 11 (64%). On average, we did 0.23 mpg better than the EPA estimates.

For Honda, we exceeded on 3 of 7 (43%). On average, we did 0.11 mpg better than the EPA estimates.

For Nissan, we exceeded on 4 of 8 (50%). On average, we did 0.33 mpg worse than the EPA estimates.

For Toyota, we exceeded on 4 of 10 (40%). On average, we did 0.40 mpg worse than the EPA estimates.
