Mazda Motor Corporation today delivered one Mazda Premacy Hydrogen RE Hybrid each to the City of Hiroshima and Hiroshima Prefecture government authorities in western Japan.

The Premacy Hydrogen RE Hybrid is Mazda’s latest hydrogen rotary engine (RE) vehicle that uses hydrogen as a fuel and features a unique hybrid system. Including the first lease of a Premacy Hydrogen RE Hybrid to the Iwatani Corporation in May 2009, Mazda has now delivered three hydrogen hybrid vehicles to fleet customers to date. The City of Hiroshima and Hiroshima Prefecture each had a rotary engine RX-8 Hydrogen RE vehicle delivered in April 2006, making this the second hydrogen-fueled model that has been handed over to the local government authorities.

The Mazda Premacy Hydrogen RE Hybrid can run on both hydrogen and gasoline thanks to a dual-fuel system that was developed for the Mazda RX-8 Hydrogen RE. The addition of a hybrid system to the Premacy Hydrogen RE significantly enhances the vehicle’s performance and contributes to its increased hydrogen fuel range of 200 kilometers, which is double that of the RX-8 Hydrogen RE.

Akihiro Kashiwagi, Mazda’s program manager in charge of hydrogen RE vehicle development, said, “As a company proudly rooted in Hiroshima, Mazda is delighted to deliver our hydrogen rotary engine vehicles to the City of Hiroshima and Hiroshima Prefecture, who are already using  the RX-8 Hydrogen RE. We are working hard to keep improving the performance of Mazda’s hydrogen-fueled rotary engine vehicles and do our part to help achieve a hydrogen energy-based society in the future.”

Based on its Sustainable Zoom-Zoom plan, Mazda is committed to pursuing harmony between driving pleasure and environmental and safety features. Mazda constantly strives to offer vehicles that “look inviting to drive, are fun to drive, and make you want to drive them again.”
