Mazda Motor has revealed its long-term vision “Sustainable Zoom-Zoom 2030”, a new technology development along with a next-generation Skyactiv-X petrol engine. Mazda's new Skyactiv-X petrol unit is claimed to be the world's first commercial petrol engine that uses compression ignition like diesel engines. This means that the new technology does not use a spark plug like the petrol engine to ignite. The fuel-air mixture ignites when compressed by the piston in the Skyactiv-X. With the compression ignition and a supercharger, fuel efficiency is up by up to 20-30 percent along with an increase in torque between 10 and 30 percent as compared to the company's current Skyactiv-G petrol unit of the same displacement. The car manufacturer also says that the new Skyactiv-X equals or exceeds the company's latest Skyactiv-D diesel engine's fuel efficiency.

According to Mazda, the new technology also extends the life of the petrol engines and lowers the emissions and furthermore, improves the driving experience. The new petrol engine will be first equipped on the Mazda CX-5 crossover when introduced in 2019. The new combustion engine combines the advantages of both gasoline and diesel engines that will deliver low-emissions, power and fuel-efficiency performance.

Mazda aims to reduce carbon dioxide emissions by 50 percent by 2030 and aims to achieve a massive 90 percent reduction by 2050. The company will continue to improve the internal combustion engine that will power the majority of cars across the world, combined with electrification technologies.

Under the Mazda Proactive Safety philosophy, the company will also develop advanced safety technologies that will help in reducing traffic accidents. This will be further enhanced by safety features like correct driving position, pedal layout and good visibility. These safety features will be made standard across the lineup by 2025. The new engine is still under development and these new technologies are currently being developed in line with Mazda's human-centered Mazda Co-Pilot Concept2 in 2020.
