Mazda announces sustainable Zoom-Zoom 2030

> Introduces SkyActiv-X, world’s first commercial petrol engine to use compression ignition

MAZDA Motor Corporation last week 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 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 longerterm 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,” said the company.

The following is an overview of “Sustainable Zoom-Zoom 2030” and the next-generation SkyActiv-X engine. generation or restrict certain vehicles to reduce air pollution.

SOCIETY “Through cars and a society that provide safety and peace of mind, create a system that enriches people’s lives by offering unrestricted mobility to people everywhere.”

Approach:

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 the iActivsense advanced safety features, which help drivers recognise and assess potential hazards; in addition to Japan, where they 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-centred Mazda Co-Pilot Concept (*2) 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.

PEOPLE “Enhance customers’ mental well-being with the satisfaction that comes from protecting the earth and contributing to society with a car that offers true driving pleasure.”

Approach:

Pursue an enhanced Jinba-ittai driving feel that will unlock people’s potential and revitalise 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. 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: maximising the zone in which compression ignition is possible and achieving a seamless transition between compression ignition and spark ignition.

Features:

This 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 fitted to improve fuel economy together deliver unprecedented engine response and increase torque 10-30% over the current SkyActiv-G petrol engine (*3).

Compression ignition makes possible a super lean burn (*4) that improves engine efficiency up to 20-30% over the current SkyActiv-G, and from 35-45% 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 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 itself. 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.” *3 Engine is still under development and figures are subject to change. *4 A condition in which the petrol-to-air ratio is reduced to a level that would not ignite in a sparkignition engine.
