Mazda Has A Plan To Save The Internal Combustion Engine

Engine / Comments

Innovation isn't just reserved for companies with mammoth budgets.

Mazda has been teasing us with its revolutionary new Skyactiv-X engine, which uses an extremely high compression ratio to allow for compression ignition (like a diesel) and in turn improve fuel economy. This new engine was expected to arrive alongside the 2019 Mazda3, and we even drove a prototype version of the car with the new engine. But when the Mazda3 was revealed with no announcement of the Skyactiv-X engine, we were a bit disappointed, to say the least.

Now, Mazda has finally published power and fuel economy figures for the new engine, which will be available for the European, Japanese, Australian, and Chinese markets in the fall of 2019. But if you live in other markets, like the United States, you are out of luck. A Mazda spokesperson told Carbuzz that the company "will announce the powertrain lineup for each market at the appropriate time." In other words, the US isn't getting the engine just yet.

Mazda says, "We are currently studying when to launch Skyactiv-X in North America, in consideration of the business environment and the market needs." But the company also wants to point out that "Skyactiv-X is not the only way we are making our cars more competitive. We are making continuous updates to our existing Skyactiv-G and Skyactiv-D engines, including adding cylinder deactivation, optimizing displacements, adding turbocharging and so on."

So even though we may not be getting Skyactiv-X just yet, we can look forward to Mazda's future inline-six engine. For those markets that are receiving Skyactiv-X, the 2.0-liter four-cylinder engine will produce 180 PS and 224Nm of torque (177 horsepower and 165 pound-feet of torque), which is not far off from specs leaked a few months ago.

The new Skyactiv-X engine also includes Mazda M Hybrid technology (a 24-volt mild hybrid system) that allows for up to 52.3 mpg on the WLTP testing cycle. It is worth noting that the WLTP cycle produces very different fuel economy numbers than the EPA's, but a rough estimate for the US is approximately 44 mpg. Mazda will offer the engine on the Mazda3 sedan and hatchback with either a six-speed automatic or six-speed manual that sends power to the front wheels. All-wheel-drive will also be available, but only on the hatchback. Full pricing information will be released next month.
