2019 Mazda Miata Fuel Economy Goes Up With New Engine Upgrades
For the 2019 model year, Mazda is making substantive changes to improve the Miata's engine and performance. The power will bump up from 155 hp to 181 hp. The engine will also rev higher. That's a good thing. Another good thing is that this bump in power and performance comes at no cost to fuel economy. In fact, it goes up.
As our chart above from FuelEconomy.Gov shows, the 2019 Miata with its manual transmission has almost no change except a 1 MPG increase to the EPA Highway estimate. However, the automatic transmission-equipped Miata gets a more significant 1 MPG bump for the Combined mileage estimate. These changes are not dramatic but it's nice to know that the performance upgrades coming this year won't come at a penalty at the pump for owners.
In Torque News testing over the past three years, the various Miata test cars we drove all seemed to get the EPA combined mileage or better.
Unfortunately, we also looked up the mileage for the Fiat 124 SPider (which is built by Mazda in its Miata plant). The Fiat Sider shows no changes at all to its mileage, which leads us to think that it will be unchanged under the hood in 2019.
The Miata is already a quick roadster. As far as we can tell, it is the fastest convertible at its price point. With a 0-60 MPH time under 6 seconds, it will only be faster given these new changes. A 14% power bump is nothing to sneeze at.
