Mazda SKYACTIV-X Engine

Introduces Mazda SKYACTIV-X - World's First Commercial Gasoline Engine


Mazda Motor Corporation 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 gasoline engine to use compression ignition. Under the original "Sustainable Zoom-Zoom" vision announced in 2007, the company has striven to offer both driving pleasure and outstanding environmental and safety performance. Part of this initiative involves the Japanese automaker introducing a next-generation engine called Skyactiv-X.

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. The following is an overview of "Sustainable Zoom-Zoom 2030" and the next-generation SKYACTIV-X engine.



1. Sustainable Zoom-Zoom 2030

Mazda has announced Sustainable Zoom-Zoom 2030 - its new long-term vision for technology development that looks ahead to the year 2030. Under the original “Sustainable Zoom-Zoom” vision announced in 2007, Mazda has striven to offer both driving pleasures combined with outstanding environmental and safety performance. More than just the launch of a revolutionary new engine, Sustainable Zoom-Zoom 2030 represents a range of initiatives and approaches that will positively impact earth, society and people in equal measure.

A Positive effect on our Earth-:

Mazda's aim is to create a sustainable future in which people and cars coexist with society and our earth. To achieve this Mazda will approach it in the following ways:

  • Expand measures for carbon dioxide reduction from a "well-to-wheel" perspective, considering emissions over the vehicle's entire life cycle.
  • Aim 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.
  • Achieve this with a policy prioritizing efficiency improvements and measures for cleaner emissions that apply in the real world.
  • In line with this policy, continue efforts to perfect the internal combustion engine, which will help power the majority of cars worldwide for many years to come and can, therefore, make the greatest contribution to reducing carbon dioxide emissions, and combine the results with effective electrification technologies.
  • From 2019, 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.


A Positive effect on Society-:

Through cars and a society that provide safety and peace of mind, Mazda will create a system that enriches lives by offering unrestricted mobility to people everywhere. In achieving this Mazda will adopt the following approaches:

  • Develop more advanced safety technologies under the Mazda Proactive Safety philosophy, working toward the goal of eliminating traffic accidents.
  • Promoting further standardisation of i-ACTIVSENSE advanced safety features, which help drivers recognise and assess potential hazards. In addition to Japan, where these features are already becoming standard, gradually make these technologies standard in other markets starting in 2018
  • Begin testing of autonomous driving technologies currently being developed in line with Mazda's human-centered Mazda Co-Pilot Concept in 2020, aiming to make the system standard on all models by 2025.
  • Using connectivity technologies, create a new business model that enables car owners to support the needs of people in depopulated areas and those who have difficulty getting around.


A Positive effect on People-:

Ensuring a positive future begins with taking care of people. Sustainable Zoom-Zoom 2030 is therefore equally committed to enhancing customers’ lives with the satisfaction that comes from protecting our earth and contributing to society with a car that offers true driving pleasure. Central to this are two important approaches:

  • Pursue an enhanced Jinba-Ittai driving feel that will unlock people's potential and revitalize them mentally and physically.
  • Based on the philosophy of "breathing life into the car," further develop KODO design to raise vehicle design to the level of art that enriches the emotional lives of all who see it.



2. SKYACTIV-X Next-Generation Engine

Over recent years Mazda has developed SKYACTIV TECHNOLOGY – a comprehensive engineering platform that has delivered some of the industries most fuel-efficient engines without sacrificing power. This is set to soar to another level with the development of SKYACTIV-X.

Technological Innovations-

  • 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.

Features of the SKYACTIV-X Engine include:

  • 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.



The vision about to become reality:

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.
