Details of Mazda’s holy grail Skyactiv-X trickle out

It might be a while before it hits our shores but here’s a rough idea of how much power the Spark Controlled Compression Ignition mill makes

Yes, Mazda is bringing back the rotary as a range extender in the near future but its mythical mastering of Spark Controlled Compression Ignition for petrol engines is the real holy grail of engine tech for the future.

Skyactiv-X is Mazda’s efforts to push the envelope of petrol engines in the search for efficiency as it isn’t subscribing to the hybrid or turbocharged small displacement ethos yet.

How does it work exactly you ask? A spark plug lights off a localised rich mixture of fuel and air to create a fireball that in turn compresses the lean mixture throughout the rest of the cylinder for a spontaneous ignition. That’s the gist of it, and although it still sounds very much like regular internal combustion, we guarantee there’s far more layers to it that are beyond the comprehension of us mortals. The conclusion is that the tech will yield the efficiency of a diesel engine but with petrol.

The Hiroshima carmaker’s been teasing the Skyactiv-X range of engines built around the tech and will initially be motivating the new Mazda 3. It mentioned that countries with more stringent emission regulations will be the first to get it, an obvious reference to European nations.

Still, details were scarce; especially on the performance figures. Mazda Slovakia though has let slip a spec sheet that Jalopnik pounced on that details the power and torque figures. That’s about 179hp and 222Nm of torque from what should be a 2.0-litre displacement. The current crop of Skyactiv-G engines in the Mazda 3 churn out 162hp and 210Nm of torque.

However, it could be a different story once it reaches our shores… if it even does. Overseas markets are very different from ours and the Skyactiv-G engine is still a part of the new Mazda 3 range for now.
