MAZDA KAI CONCEPT AND VISION COUPE

Mazda KAI Concept

Mazda has revealed two concepts at the 2017 Tokyo Motor Show, the Mazda KAI CONCEPT, a compact hatchback, and the Mazda VISION COUPE.

Featuring the next-generation SKYACTIV-X petrol engine, the KAI CONCEPT embodies the technology, engineering and styling concepts that will define the coming generation of Mazdas. Refinements in all areas of dynamic performance have produced a considerably quieter, more comfortable ride and enhanced performance.

The Mazda stand also features the all-new Mazda CX-8, a three-row SUV going on sale in Japan later this year, as well as the 2018 Mazda MX-5 and 2018 Mazda MX-5 RF. The latter offer a number of enhancements such as a higher quality ride, more peaceful cabin and a wider choice of body colours.

SKYACTIV-X is the world’s first commercial gasoline engine to use compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston.

A proprietary combustion method called Spark Controlled Compression Ignition overcomes two issues that had impeded commercialization of compression ignition gasoline engines: maximizing the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition

This new proprietary combustion engine combines the advantages of gasoline and diesel engines to achieve outstanding environmental performance, power and acceleration performance.

Compression ignition and a supercharger fitted to improve fuel economy together deliver unprecedented engine response and increase torque 10 – 30 percent over the current SKYACTIV-G gasoline engine.

Compression ignition makes possible a super lean burn that improves engine efficiency up to 20 – 30 percent over the current SKYACTIV-G, and from 35 – 45 percent over Mazda’s 2008 gasoline engine of the same displacement. SKYACTIV-X even equals or exceeds the latest SKYACTIV-D diesel engine in fuel efficiency.

With high efficiency across a wide range of rpms and engine loads, the engine allows much more latitude in the selection of gear ratios, providing both superior fuel economy and driving performance.
