The hatch concept shows off a long hood, angular headlights, and possibly a more raked roofline than the current Mazda3.
Although the Japanese carmaker hasn't officially confirmed that the new showcar previews the next Mazda3, it has been referred to as a "product concept model" and "compact hatchback", and given its basic dimensions, and the fact that the Mazda3 is due for replacement before the current Mazda2, we'd put our money on this being the company's next Golf challenger in drag.
The Skyactiv-X technology forces the petrol to combust under extremely high compression, a move that will increase fuel efficiency by up to 17 per cent.
Mazda hasn't announced performance specs for the new compact hatch. That, of course, can mean anything. With the Mazda 3 that's now on sale having launched in 2013, expect the Tokyo Show vehicle to morph into something more production-ready next year before launching globally in 2019. "We will showcase a concept model with the design and technologies that will define a whole new generation of Mazda cars", said Mazda CEO Masamichi Kogai.
A report last month gives us other clues on what we might expect for this model.
For its part, the style study to be presented by Mazda will lift the veil on future evolutions of the KODO design language, which was first introduced five years ago with the Mazda CX-5. The new four-door coupe concept may also be the brand's annual return of the rotary engine teaser, much like the previous RX-Vision concept. But for now, Mazda is keeping quiet on specific details of its design concept.
Mazda will also show off its diesel-powered CX-8 three-row SUV, while a special-edition MX-5 with a red canopy and auburn leather interior will be the other Tokyo debut for Mazda.
