2019 Mazda3 will have Skyactiv-X

Although we've seen the stunning Mazda Kai concept car that's expected to preview the all-new 2019 Mazda3, the Japanese automaker is keeping the production version very much under wraps for now. It refuses to confirm that the new Mazda3 will be the same as or similar to the Kai concept, but nobody is outright denying it either. What we do know is the new 3 will be the first model to utilize the automaker's new-generation Skyactiv-X SPCCI (Spark Controlled Compression Ignition) engine, and some journalists have even been able to drive it. But before anyone gets too excited, the test car was hidden underneath the body shell of the current Mazda3.


What actually is Skyactiv-X?

At the moment Mazda doesn’t seem to be going all-in yet with hybrid, plug-in hybrid or all-electric powertrain technology, but is instead going down the route of developing increasingly lightweight and efficient gas engines. We've been enjoying Mazda with excellent Skyactiv G (gas) and Skyactiv D (diesel) engines for a while now, but the Skyactiv-X is an entirely new generation of engines that moves the technology further forward. These new engines use spark ignition as well as compression ignition to achieve a fuel/air ratio that's as close to perfection as currently possible, and it's actually the first time this has been done. What this means to the consumer is an engine that's around 20% percent more energy efficient than a current Skyactiv G engine and about the same as a Skyactiv D, which is a fuel economy rating of around 4.7 L/100 km.

Because these engines have a wide torque band, there's actually no need for one of those 7, 8, 9 or even 10-speed automatic transmission that are now becoming increasingly common. The 2.0-litre unit going into the new Mazda3 develops a maximum of 190 horsepower, with 220 Nm of torque at 1,800 rpm and a maximum 230 Nm of torque arriving between 4,000 and 5,000 rpm, so a six-speed transmission is more than adequate.


The philosophy behind Skyactiv-X

It can't have escaped your notice there's a fierce debate going on about the best way to power vehicles in the coming years, with most politicians being quick to seize on the "zero tailpipe emissions" bandwagon. The problem with that philosophy is it largely ignores the environmental cost and carbon emissions associated with the battery electric models favoured by those on that particular bandwagon. Electricity often needs dirty coal, oil and gas to generate it in the first place, and that's before we even start on the mining of lithium and the manufacturing of those batteries that's also far from environmentally friendly.

Instead of worrying about and fixating on tailpipe emissions to the exclusion of all else, Mazda is prefers to concentrate on what it refers to as "oil well to wheel," or in other words, the total environmental cost. There's actually no way that the world’s cars can all be electric by 2040 as some hope, and by 2035 even the most ardent environmentalists admit most vehicles will still have an internal combustion engine, even if they're being used as part of a hybrid drive. This is why Mazda wants to concentrate on developing the most efficient petrol engines possible, to eventually combine them with hybrids.

There will be a lot more to the 2019 Mazda3 than the just its Skyactiv-X engine, of course, so stay in touch with us here at Yarmouth Mazda so we can keep you up to date with the latest news regarding this exciting new model.
