In March 2007, Mazda announced its long-term vision for technology development, "Sustainable Zoom-Zoom." The section on powertrain development describes Mazda's intention to maintain its focus on internal combustion engines, to pursue hydrogen combustion technology in preparation for the forthcoming hydrogen society, and through this process of evolution, to offer pragmatic technologies to support the social infrastructure as it develops.
As well as emitting no CO2, Mazda's hydrogen rotary engine eco-cars use internal combustion, and so deliver a true engine feeling to provide the driver with lots of Zoom-Zoom driving pleasure. Going forward, Mazda will advance its development programs to improve combustion efficiency and hybrid technology, and further evolve its hydrogen rotary engine vehicles.
As the world's only manufacturer of hydrogen rotary engine vehicles, Mazda intends to support this advance towards the creation of a sustainable automotive society based on hydrogen energy.

- System Configuration
Moving on from the RX-8 Hydrogen RE, Mazda is currently developing the Premacy Hydrogen RE Hybrid, which is a more practical and advanced hydrogen rotary engine vehicle. It includes a newly developed hybrid system and inherits the RX-8's dual fuel system. As such, it is the world's first dual-fuel hydrogen hybrid vehicle.
In the new Premacy Hydrogen RE Hybrid, the power unit output is increased by 40% compared to the RX-8 Hydrogen RE, significantly boosting acceleration and improving fuel efficiency. It also doubles the hydrogen fuel range of the RX-8 Hydrogen RE to 200 kilometers. The extremely efficient and responsive hybrid system in Mazda's latest eco-car enhances the fuel economy and power output and delivers a true engine feel, enabling more spirited Zoom-Zoom driving.
Furthermore, the environment was taken into consideration in the use of materials. The Premacy Hydrogen RE Hybrid features several injection molded interior plastic parts, such as the shifter panel and lower console panel, that are made from plant-derived bioplastic. The world's first 100% plant-derived biofabric is used for the seat covers and door trim.
The Premacy Hydrogen RE Hybrid is scheduled to begin commercial leasing during FY2008 in Japan.
