The 2019 Mazda MX-5 Miata Finally Has the Engine It Deserves
We have cared a lot about the Mazda MX-5 Miata for nearly three decades. So, too, have the thousands of loyal Miata owners who race their cars, modify their cars, and take them to Miata Club meets. But do you know who cares about the Miata even more? Mazda. The little roadster truly is the company’s pride and joy, a North Star doubling as its philosophical center.

Thus, it isn’t surprising that Mazda is both steadfast about keeping the Miata true to its original missive and always looking for ways to make it better. The precedent of continuous improvement could be seen in the first three generations of MX-5, each of which received tweaks throughout its life cycle. It’s now time for the current, fourth-generation Miata (ND to the cognoscenti) to get better; for 2019, that means a revised 2.0-liter inline-four Skyactiv engine.
Previously, the ND Miata was powered by a 2.0-liter inline-four that was little more than a Mazda 3 engine turned longitudinally and stuffed into the MX-5’s small engine bay. Vehicle dynamics engineer Dave Coleman admits that the car was originally designed around the less powerful 1.5-liter four-cylinder that’s available in other markets and that by the time the decision was made to install a bigger engine in the Miata bound for the United States, it was too late to truly fine-tune the 2.0-liter for a sports-car application. Of course, the engine itself was hardly a dud—responsive and eager, it made the current car quicker than any Miata before it in our testing despite its meager 155 horsepower.

Coleman describes the engine’s changes for 2019 as “standard hot-rodding procedure.” The throttle body, intake valves, exhaust valves, and their corresponding ports are all larger, while the pistons and connecting rods are lighter, the crankshaft is stiffer, and the fuel-injection system runs at a higher pressure. As a result, the engine revs higher (redlining at 7500 rpm versus 6800 rpm) and puts out 26 more horsepower and 3 more lb-ft of torque for new totals of 181 horses and 151 lb-ft.
