Yahoo Autos Mazda Is Developing a New Four-Cylinder Engine Called Skyactiv-Z
Mazda has revealed that it's working on a new four-cylinder engine called Skyactiv-Z.
The new engine is set to replace the Skyactiv-G versions in the United States, and it will launch in 2027.
Mazda says the Skyactiv-Z will use the Lambda 1 air-fuel ratio to improve emissions; that will eventually apply to the brand's six-cylinder engines too.
Mazda continues to invest in internal combustion. The company has revealed that it's currently developing a new gas-powered four-cylinder engine that will introduce the latest Skyactiv technology. Called Skyactiv-Z, it will eventually replace the Skyactiv-X engines sold abroad as well as the Skyactiv-G engines that are sold in North America.
Mazda quietly shared some of the details back in August as part of a presentation on its quarterly financial results, as reported last week by Motor1. Mazda says the new Skyactiv-Z engine will be significantly more efficient to meet tightening emission regulations, such as the CARB-approved LEV IV standards in the United States. It will use the Lambda 1 air-fuel ratio, which is a perfectly balanced mixture throughout the entire rev range that helps reduce tailpipe emissions at full power.
Mazda didn't reveal any other technical details about the new four-cylinder engine. We don't know how much power it will have or if it will be turbocharged. While we also don't know what models it will be available on, the company says it will launch sometime in 2027. Mazda plans to eventually expand the Skyactiv-Z technology to its inline-six engine too.
It's worth pointing out that the company is also still working on a new rotary engine. That fact was mentioned earlier this year when Mazda announced alongside Toyota and Subaru that the trio is collaborating on next-gen engines. For Mazda's part, it's working on rotary EV systems featuring either one or two rotors. There's no timetable for when development will be completed, but Mazda says it's "making good progress."
