Mazda to introduce next-gen engine in 2019 plus much more...
09 August 2017
Mazda announces a new long-term vision for technology development, including a next-generation engine and autonomous driving tech on all models by 2025.
Under the original “Sustainable Zoom-Zoom” vision announced in 2007, 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.
Sustainable Zoom-Zoom 2030
• 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 prioritising 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
• 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-ACTIVSENSE 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 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
SKYACTIV-X next-generation engine
• 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 commercialisation of compression ignition gasoline engines: maximising 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 efficient environmental performance, power and acceleration performance
• Compression ignition and a supercharger fitted to improve fuel economy together deliver good 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
