The Mazda3 small car and CX-30 small SUV are set to shortly add Mazda's much-touted SkyActiv-X technology to their respective line-ups.
The new engine tech is headlined by the introduction of what Mazda calls “spark-controlled compression ignition” technology, which adjusts the fuel injection mixture “to the point where the lean mixture rapidly combusts” on a new compression stroke. The technology does not do away with a spark plug entirely like a diesel engine, but requires the spark to fire to combust a leaner fuel mixture.
The brand has promised that this technology will reduce emissions while “retaining the same joy of driving”. The SkyActiv-X variants will also come bundled with Mazda’s mild ‘M Hybrid’ technology, which features a belt-driven starter generator and a 24V lithium-ion battery. It is said to recycle energy recovered during deceleration, and using the electric motor “assists the engine”.
Interestingly, Mazda will offer the new engine with a six-speed manual transmission as well as an automatic in the Mazda3, and as an automatic all-wheel drive only via a six-speed torque-converter in the CX-30 . The new engine, dubbed X20, will only be available in top-spec Astina trim for both models.
The 2.0-litre non-turbo powerplant produces 132kW/224Nm, and in the Mazda3 manual will consume 5.3L/100km. Importantly, the emissions from the engine have dropped to 127g/km, a significant decrease on the current 2.0-litre's 144g/km.
Mazda promises the tech will retain the "joy of driving" while reducing emissions.
The pricing for each variant represents a $3000 jump over the respective current top G25 Astina trim for both the Mazda3 and CX-30.
SkyActiv-X versions of the Mazda3 are set to arrive next month, while the CX-30 will launch in September.
The brand has also promised that there will be no surprise servicing costs by opting for the new engine.
