2017 Mazda 3 vs 2020

What's the difference?

For over a decade, the Mazda3 has been part of a three-way battle for supremacy in the Australian small car market. The 2004 original threw the felines among the flying rats when launched, transforming the then-dowdy 323 into a stylish, well-equipped, and well-priced contender for Toyota's segment-dominating Corolla, and later, Hyundai's value-packed i30.

In 2017, the battle is still raging. Late 2016 saw a mild update to Mazda's flagship hatch and sedan range to add a few bits and bobs to the its already finely-judged specification. The Corolla stayed pretty much the same, and just this month Hyundai dropped what is now an annual tradition, an absolute cracker of a new car. This time, the all-new i30.

As you can see, Mazda has never had it easy, and it's a testament to the 3's quality, style and ever-growing reputation that it continues to hold its own in the top three.

You get exposed to a lot of cutting-edge technology doing this job.

We get to drive new drivetrain technology all the time as manufacturers are racing to get their emissions down – usually it has to do with electrification or hybridization.

What’s especially rare about the new tech sitting under the bonnet of this unassuming Mazda3 is its sole purpose seems to be extending the life of the combustion engine beyond its previously imagined use-by date.

It does so by blending some of the principles of diesel combustion technology with the latest in computer-controlled fuel-injection methods.

It’s a distinctly different approach to the future from the Japanese brand, so what’s ‘SkyActiv-X’ all about? Will you notice a difference? Does it drive well? And, what else is in the box?

We tested a Mazda3 SkyActiv-X for several days at its Australian launch to answer these questions, and more.
