Mazda says its new compression ignition petrol engine will have 10-30% more torque than the current Skyactiv-G petrol engine pictured and super lean burn that improves efficiency up to 20-30%

Mazda Motor Corporation's new Sustainable Zoom-Zoom 2030 technology development strategy includes its petrol compression ignition engine which it will call Skyactiv-X and launch in 2019.

It will be a claimed world first, using 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 commercialisation of compression ignition petrol engines: maximizing the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition.

Mazda claims its new proprietary combustion engine combines the advantages of petrol and diesel engines to achieve outstanding environmental performance, power and acceleration performance.

Compression ignition and a supercharger improve fuel economy together to deliver "unprecedented" engine response and increase torque 10-30% over the current Skyactiv-G petrol engine.

Compression ignition makes possible a super lean burn that improves engine efficiency up to 20-30% over the current engine and from 35-45% over Mazda's 2008 petrol engine of the same displacement. Skyactive-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.

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. 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.


Under its new strategy, Mazda will expand measures for carbon dioxide reduction from a "well-to-wheel" perspective, considering emissions over the vehicle's entire life cycle.

It aims to reduce corporate average "well-to-wheel" carbon dioxide emissions to 50% of 2010 levels by 2030, and achieve a 90% reduction by 2050. 

It will achieve this with a policy prioritising efficiency improvements and measures for cleaner emissions that apply in the real world.

In line with this policy, it will 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, it 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.

It also plans to develop more advanced safety technologies under the Mazda Proactive Safety philosophy, working toward the goal of eliminating traffic accidents, further enhance safety fundamentals, such as correct driving position, pedal layout and good visibility, and standardise them across all models, promote further standardisation of i-Activ advanced safety features, which help drivers recognize and assess potential hazards, in addition to Japan, where they are already becoming standard, and gradually make these technologies standard in other markets starting in 2018.

It will also begin testing of autonomous driving technologies currently being developed in line with its human-centered Co-Pilot Concept in 2020, aiming to make the system standard on all models by 2025.

Using connectivity technologies, it will 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.
