Mazda Delivers Premacy Hydrogen RE Hybrid to Iwatani Corporation for use in Kyushu
HIROSHIMA, Japan—Mazda Motor Corporation today delivered a Mazda Premacy Hydrogen RE Hybrid to Iwatani Corporation, an energy development company based in Japan. The Premacy Hydrogen RE Hybrid is Mazda’s latest hydrogen rotary engine (RE) vehicle which uses hydrogen as a fuel and features a unique hybrid system.
The delivery marks the fifth Premacy Hydrogen RE Hybrid to be leased by Mazda, and the second to be provided to Iwatani Corporation. The first model was delivered to Iwatani Corporation in May 2009. The new vehicle will be mainly used for business purposes and will be based at the Kitakyushu Hydrogen Station. It is the first hydrogen rotary engine vehicle to be leased in Kyushu, the most southwesterly of Japan’s four main islands.
The Mazda Premacy Hydrogen RE Hybrid uses a unique hybrid system with power delivered to the vehicle’s wheels by an electric motor. This powertrain substantially enhances the driving performance and boosts the hydrogen fuel driving range to 200 kilometers, twice the range of Mazda’s previous hydrogen vehicle, the RX-8 Hydrogen RE. The Premacy Hydrogen RE Hybrid can run on gasoline as well as hydrogen thanks to a dual-fuel system that was developed for the RX-8 Hydrogen RE.
Mazda’s program manager in charge of hydrogen RE development, Akihiro Kashiwagi, said, “Mazda is pleased to deliver a second Premacy Hydrogen RE Hybrid to the Iwatani Corporation. Iwatani has been a leader in advancing the use of hydrogen energy for years. We’re doubly delighted that the vehicle will be used in Fukuoka prefecture, an area known as a research hub for the real-world use of hydrogen energy.”
