Mazda’s mission to save the internal combustion engine continues on by giving its game-changing HCCI engine, Skyactiv-X, the body it deserves. Making its formal debut at the 45th Tokyo Motor Show 2017, the KAI CONCEPT is a production concept that gives everyone the first glimpse of the all-new Mazda3.

With a name that means “pioneer”, the KAI CONCEPT uses Mazda’s Skyactiv-X engine. It is also underpinned by a brand-new vehicle architecture called Skyactiv-Vehicle Architecture. This new platform is developed keeping in mind a human-centric design philosophy that maximizes the human body’s inherent ability to balance itself. With the human body easily able to balance itself in response to driving inputs, this new vehicle architecture provides a more responsive driving feel resulting in the ultimate “Jinba-ittai” driving feel.



The platform has been optimized including re-designed seats that keep the pelvis upright to maintain the spine’s natural S-curve. It uses multi-directional ring structures to transmit inputs without delay and a chassis structure that interacts with each part to smoothly control energy transfer.

The KAI CONCEPT is a showcase of Mazda’s technology, engineering, and design for the immediate future. It is an evolution of Mazda’s KODO – Soul of Motion philosophy featuring muscular and solid proportions as well as a play of surfaces and reflection on the body sides. The lack of character lines on the sides was a challenge that Mazda overcame resulting in a car that looks like it’s made from one solid mass.It’s also said to offer refinement in various areas such as dynamic performance, NVH, and comfort.
