Mazda Motor Corporation has announced, “Sustainable Zoom-Zoom 2030,” a new long-term vision for technology development that looks ahead to the year 2030. As part of the new technology to achieve this vision, the company disclosed plans to introduce a next-generation engine called SKYACTIV-X in 2019. SKYACTIV-X will be the world’s first commercial petrol engine to use compression ignition.1
Under the original “Sustainable Zoom-Zoom” vision announced in 2007, the company has endeavored to offer both driving pleasure and outstanding environmental and safety performance. In light of the rapid changes taking place in the automotive industry, the new vision takes a longer-term perspective and sets out how Mazda will use driving pleasure, the fundamental appeal of the automobile, to help solve issues facing people, the earth and society.
David Hodge, Managing Director Mazda New Zealand believes the motor vehicle industry is going through some of its most significant changes and it is great to see Mazda continue to demonstrate innovation in its long term technology strategy.
“The first generation SKYACTIV engine really made its mark in New Zealand due to both its power and environmental performance. The exciting changes planned for the next-generation SKYACTIV-X will further highlight the company’s commitment to the environment while still delivering the thrill of driving great cars.”
As part of “Sustainable Zoom-Zoom 2030” Mazda will expand measures for carbon dioxide reduction from a “well-to-wheel” perspective, considering emissions over the vehicle’s entire life cycle. Its aim is to reduce corporate average “well-to-wheel” carbon dioxide emissions to 50 percent of 2010 levels by 2030, and achieve a 90 percent reduction by 2050.
This will be achieved by prioritising efficiency improvements and measures for cleaner emissions that apply in the real world.
From 2019, the company will start introducing electric vehicles and other electric drive technologies in regions that use a high ratio of clean energy for power generation or restrict certain vehicles to reduce air pollution.
More advanced safety technologies will also be developed under the Mazda Proactive Safety philosophy, working towards the goal of eliminating traffic accidents.
Testing will begin in 2020 of autonomous driving technologies currently being developed in line with Mazda’s human-centered Mazda Co-Pilot Concept2 with the aim to make the system standard on all models by 2025.
The SKYACTIV-X next-generation engine with its proprietary combustion method called Spark Controlled Compression Ignition will combine the advantages of petrol and diesel engines to achieve outstanding environmental performance, power and acceleration performance. It will be the world’s first commercial petrol engine to use compression ignition, in which the fuel-air mixture ignites spontaneously when compressed by the piston. By maximizing the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition, Mazda will overcome two issues that had previously impeded commercialization of compression ignition petrol engines.
This new proprietary combustion engine combines the advantages of petrol and diesel engines to achieve outstanding environmental performance, power and acceleration performance. Using compression ignition and a supercharger fitted to improve fuel economy the result is an unprecedented engine response and 10-30 percent increase in torque over the current SKYACTIV-G petrol engine3. Compression ignition also provides a super-lean burn4 that improves engine efficiency up to 20-30 percent over the current SKYACTIV-G, and from 35-45 percent over Mazda’s 2008 petrol 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.
Moving forward Mazda hopes to help create a future in which people, the earth and society can coexist with cars, to enrich people’s lives through a car ownership experience that celebrates driving, and to become a brand with which customers feel a strong emotional connection.

Meanwhile the car is driving “virtually” with a firm grasp of the movements of the driver and the car. In unexpected situations, such as a sudden loss of consciousness, the car will override the driver, automatically contact emergency services and drive safely to the most appropriate location.
