Mazda’s MX-5 Miata roadster has never been a automobile consumed with power. In fact, a graphic lack of horsepower is partial of a back-to-basics sports-car appeal. The current-generation Miata indeed has reduction output—just 155 ponies!—than a automobile it replaced. But Road Track has unclosed evidence that that could shortly change.
In an annual VIN notice sent to a National Highway Traffic Safety Administration (NHTSA), Mazda lists a 2019-model-year MX-5 Miata’s engine as a 2.0-liter four-cylinder with 181 horsepower, 26 some-more than it has now and a many ever from a bureau Miata. (The second-generation Miata’s turbocharged Mazdaspeed various usually done 178 horsepower.) How Mazda reaches that series (assuming a NHTSA filing is accurate) is a million-dollar question.
The NHTSA request does not specify whether a 2.0-liter engine in doubt is an expansion of a same Skyactiv-G section now in a Miata or something else, like, say, a brand’s stirring high-tech gas-fed supercharged, compression-ignition-capable Skyactiv-X engine. The X is slated to seem someday in a subsequent year or dual in a next-generation Mazda 3 compact, and a rough outlay figure roughly matches a 181-hp series listed for a 2019 Miata.
On a other hand, a Skyactiv-G is adhering around via a Mazda lineup for a foreseeable destiny as a entry-level charity positioned underneath a Skyactiv-X. And Mazda has told us it will continue to rise a G going forward. As such, a 26-hp bump isn’t out of a question, presumption a G would be given better intake and empty plumbing and tweaks to engine internals to raise its 6800-rpm redline by a few hundred revolutions per minute. (Horsepower being distributed as a duty of engine speeds and torque generally means that a faster an engine spins, a some-more energy it’ll make.) The Skyactiv-G engine already boasts an impossibly high 13:1 application ratio and runs on reward gasoline.

Maybe Mazda will occupy a tiny supercharger like that propitious to a Skyactiv-X engine, or a likewise compress turbocharger, nonetheless conjunction is mentioned in a NHTSA filing. What is certain is that if a Miata is a blast with 155 horsepower (and also surprisingly quick, interjection to a light weight), it’ll be a full-on, Molotov-cocktail-chucking demonstration with 181 ponies underneath a hood.
Mazda’s request filing also reveals changes in store for a Miata’s trim-level structure. Look for a lineup to grow from Sport, Club, and Grand Touring trims (the latter dual a usually choices for today’s hardtop Miata RF) to embody a bottom SV spec and a new range-topping SE (special book in Mazda-speak)—with a RF now relating a softtop roadster trim for trim. More energy and some-more choices? We can’t wait for 2019.
