In case you want a refresher, the SkyActiv-X engine options compression ignition sometimes present in diesel engines, enabling using a a lot leaner air-fuel ratio supplied via a supercharger.

The expertise is so efficient, the corporate says, that the two.zero litre SkyActiv-X engine’s gasoline effectivity equals and even exceeds that of the 1.5 litre SkyActiv-D diesel engine. The mill can be claimed to supply improved response and between 10 to 30% extra torque in comparison with the two.zero litre SkyActiv-G engine, which Mazda says is equal to the bigger 2.5 litre motor.
