TrueDelta Reviews the Real Gas Mileage of the Mazda MX-5 Miata

Mazda MX-5 Miata Real Gas Mileage: Pros
YearComment
2016 Nothing has improved more with the Mazda MX-5 Miata's latest redesign than its fuel economy. The 2015 managed only 21 mpg city and 28 mpg highway in the EPA's tests, disappointing for such a light car powered by a naturally aspirated 2.0-liter engine. The new car tests much better: 27/34 with a manual transmission and 27/36 with an automatic. The MINI Cooper S Roadster was about equally efficient when equipped with a manual transmission (26/35), a little short with an automatic (25/34). The new MINI Convertible, if it shares the Hardtop's EPA ratings, won't be as efficient with a manual transmission (23/33) but will be as competitive as its predecessor with an automatic (26/33). The Scion FR-S barely out-economizes the old Miata with a manual (22/30) but is just a couple mpg short of the new one with an automatic (25/34). Premium fuel is recommended in all of these cars. The new Miata can use regular unleaded at the cost of some responsiveness. In my real-world driving of the new Miata with an automatic transmission the trip computer reported a suburban average around 30 mpg. On a 60-mph highway the average can reach 40, about 4 mpg better than a Scion FR-S and 5 mpg better than a MINI JCW Clubman, both tested with manual transmissions. Drive at 75 mph with the top down, though, and the reported average will fall to 34 mpg. The largest fuel economy advantage over the Scion FR-S appeared when both were flogged along Ohio's Route 26. The Scion's fuel economy dipped into the high teens, but the Mazda's only into the mid-20s. The most likely reason: the torquier, far less peaky Mazda engine doesn't have to be revved nearly as high to reach its sweet spot. The JCW Clubman, its turbo reducing the need for fuel-guzzling runs to the red line, fell between the two with a "spirited driving" average around 20 mpg. Overall, with the redesign the Miata's fuel economy has gone from worst to first. see full Mazda MX-5 Miata review
Mazda MX-5 Miata Real Gas Mileage: Cons
YearComment
The first four "why nots" shouldn't have come as a surprise to anyone. This one might. I didn't ding the MX-5 Miata's engine for its power output, but I am going to ding it for its fuel input. While EPA ratings of 21 mpg city and 28 mpg are hardly abysmal, the FR-S does better (22/30) and a 315-horsepower Porsche Boxster S does about as well (20/28). With one of Mazda's new SKYACTIV engines, the Miata would go much farther on a gallon of gas. (The 2,900-pound Mazda3 is rated 27/39.) But this engine won't happen until the Miata is again redesigned. see full Mazda MX-5 Miata review
