Is this the internal combustion engine savior?
Mazda is rightly proud of its new SkyActiv-X engine with Spark Controlled Compression Ignition technology. With emissions standards becoming more stringent than ever, many automakers are adding hybrid assist systems as a way to maximize fuel economy and, in some cases, even improve performance. But Mazda prefers to keep developing internal combustion. Question is, what are the specs for SkyActiv-X?
Jalopnik managed to get a hold of some leaked information and we now have some figures. The information came from Mazda of Slovakia, which has the SkyActiv-X engine down for 181 metric horsepower and 222 nm of torque, or about 178.5 hp and 163.7 lb-ft torque when converted.
It's important to note these are European figures and may not be completely identical to America's version. Unfortunately, the leaked documents do not reveal the engine's displacement, but the SkyActiv-X prototype fitted into a previous generation Mazda3 hatchback we drove a while back was a 2.0-liter four-cylinder. We doubt that'll change.
Given those aforementioned specs, let's do some comparing. The 2.0-liter SkyActiv-G from the previous generation Mazda3 offered up 155 hp and 150 lb-ft while the new 2019 model has a 2.5-liter SkyActiv-G good for 186 hp and 186 lb-ft.
Essentially, it appears the latest SkyActiv-G and new SkyActiv-X engines offer similar outputs, but the latter is expected to be more fuel efficient. Losing a bit power for improved efficiency is a trade-off a majority of buyers will be just fine with.
The leaked documents further reveal SkyActiv-X will be available only on the higher trim GT and GT Plus with both manual and automatic transmissions. However, all-wheel drive will only be offered with the hatchback body style. Given that Mazda has big plans for SkyActiv-X technology, chances it will be applied to the rest of the lineup, but also improved over time with even greater power outputs possible.
