The 45th Tokyo Motor Show is just a few weeks away and carmakers are continuing to reveal new details on some of the products and concepts that they plan to reveal come opening day. Mazda will be arriving at the said motor show with two new concepts that will preview an all-new model, as well as the brand's future design direction.

Beginning with the concept painted in red, the hatchback highly likely previews the new-generation Mazda3 hatchback. Based on the photo, the five-door gets more rounded edges as well as redesigned taillights. Apart from that, the concept will also come with a new SkyActiv-Vehicle Architecture along with a 'human-centered design philosophy for optimal functionality'.

Driving the hatchback concept will be the new SkyActiv-X powertrain. It is set to become the world's first commercial gas engine that uses compression ignition for a cleaner, more efficient combustion.

It is not clear, however if this previews the next-gen 6 sedan but both it and the 3 are due for a replacement.
