As NZ introduction nears, it’s timely to remind what a breakthrough this tech potentially represents.

“IT is a combustion technology – and that combustion can work on any size of engine, so it doesn’t need to be a 2.0-litre; it can be in other things…”

As New Zealand ramps up to receive our first Mazda vehicles with the brand’s SkyActiv-X engine technology, this comment from the marque’s marketing director in Australia is a good reminder about the full potential of the world’s first production-ready petrol that uses compression ignition.

For now, two models off a common platform have adopted what Hiroshima formally calls it’s SPCCI – for spark plug controlled compression ignition – tech: The Mazda3 and the CX-30 crossover.

Those cars run together in every market where SkyActiv-X places; including in Australia, though there the introductions are staged. The road car first, from this month, and the CX-30 following in September.

Will that double act also provision in New Zealand? All odds favour that outcome, but the local distributor isn’t yet ready to make an announcement. Media have been notified of a conference dedicated to SkyActiv discussion will occur in four weeks’ time.

Anyway, when Mazda Australia staged its press introduction to the cars last week, marketing head Alistair Doak made a good point by reminding that simply because SPCCI – and the mild hybrid involvement it also delivers (more on this in a bit) dubbed Mazda M Hybrid - only packages for now in a 2.0-litre four cylinder form doesn’t mean it cannot reach into other displacements or cylinder counts in the future.

Doak provided the comment that introduces this story as a response to being asked whether the new 2.0-litre four-cylinder could power a vehicle as large as the Mazda CX-9, as an example.

He went on to suggest hinted that Mazda might choose to upscale SkyActiv-X to an engine of larger displacement. But equally true, he suggested, there was no reason the maker couldn’t develop a smaller engine employing the same process.

Which means? Sorry, Doak – doubtless because he is a former motoring writer – was too canny to fall into letting out any secrets in respect to future rollouts.

However, he hinted that the option likely won’t remain the preserve of flagship models in the Mazda3 and CX-30 ranges for long.

Currently, he said, there were no plans to expand SkyActiv-X in other models, “but it’s certainly available to us in Mazda3 and CX-30. It’s available in Europe in those models, across all grades… or most grades…

“So there is that availability… should the desire from customers be there. But ultimately, it’s up to us, from a marketing and brand point of view to tell the story, and explain what SkyActiv is,” he explained. 

“If people like that story, and are curious, then hopefully they’ll come and test-drive, and hopefully they’ll buy.

“If the demand is there, then absolutely, we’ll meet that demand. But we haven’t started yet, so it’s very much a hypothetical at this point.”

SkyActiv-X is certainly a new chapter, in that it marks the start of Mazda’s corporate goal to reduce ‘well-to-wheel’ emissions by 50 percent from 2010 to 2030.

It has been in production since last August, and was first revealed to the world in 2018, so you might wonder why it has taken so long to get here.

Coronavirus likely hasn’t been much help but even before that global calamity Mazda had determined to focus first on servicing western Europe, for simple reason that countries there encourage low CO2 engines. The Mazda3 hits that button, if not quite as effectively as a hybrid, with a claimed emission of 127 grams per kilometre. 

Sure enough, the make has seen a brisk take-up of the technology in those initial target markets, to the point where the acceptance rate has been much higher than it anticipated.

"Since we launched the engine, we are seeing a very encouraging feedback: 60 percent of the orders for the Mazda3 are currently for cars equipped with the Skyactiv-X engine, as well as 45 percent of orders for the Mazda CX-30 crossover," Mazda Europe CEO Yasuhiro Aoyama said last August. That rate has not decreased since then and the demand has stretched Mazda’s capabilities.

Still, it seems to have now found ability to service our part of the world. Our neighbour reckons it can achieve good supply of the Mazda3, which it takes in manual and automatic formats, and the CX-30, which it will achieve purely in auto. NZ might be even more selective and take just the auto.

SPCCI’s potential to deliver will be eagerly monitored. For one, everyone will be keen to establish the value aspect; a focus that becomes important because this is a premium priced engine, more expensive than the ‘regular’ four cylinders that provision in the two models in 2.0-litre and 2.5-litre formats.

In our neighbour’s case the SkyActiv-X models cost $NZ3300 more than the priciest 2.5s. It’s expected Mazda NZ will do as other markets have and package the powertrain into its plushest trim level, which in this market is called Takami. That’ll be a new fit out for the CX-30, where the current trim line tops with a Limited provision.

As said, SkyActiv-X uses compression ignition typical of a diesel, but with a petrol engine which the brand says helps blend the high-revving character of a petrol engine with the fuel efficiency and torque of an oiler. 

Capable of both spark ignition and compression ignition, the engine can utilise the two types of combustion while operating in tandem.

To further maximise fuel efficiency, the engine features an integrated, belt-driven starter generator and 24-volt lithium-ion battery which assists the engine and recoups lost energy during deceleration. 

The addition qualifies this to be considered the first hybrid offering in Mazda’s local line-up. Next year, of course, it seems set to deliver its first electric car, with the MX-30.

As explained in previous stories, the attraction of SkyActiv-X is that it presents an intriguing ‘cake and eat it’ proposal – decent pep and yet also potential to deliver very good parsimony.

European numbers show the new 2.0-litre four-cylinder engine will generate 132kW and 224Nm of torque, while fuel economy of 4.3 litres per 100km from the manual is getting close to Toyota Prius levels of efficiency. Be aware that this figure is the result of Mazda using the NEDC testing regime, a format that has now been largely shelved on grounds it’s results are difficult to achieve in everyday driving. Using the now preferred 'real world' (WLTP) fuel economy formula, the claimed consumption is 5.4L/100km.

Still, that thrift and the power outputs place it above the existing 114kW/200Nm 2.0-litre unit and, while the 2.5-litre engine has more punch, with 139kW/252Nm, it also achieves it by using more fuel, 6.6 litres per 100km in an automatic Mazda3 on the test cycle.
