Mazda Motor Corporation has delivered one RX-8 Hydrogen RE vehicle each to its first two corporate customers for the model, Idemitsu Kosan in Tokyo and Iwatani International Corporation in Osaka, Japan.

RX-8 Hydrogen RE cars are equipped with a rotary engine and feature a dual-fuel system that allows the driver to select either hydrogen or petrol.

The vehicles are based on Mazda's original body design but with special company decals for each customer.

The delivery of these vehicles for fleet use marks the world's first case of leasing an internal combustion engine vehicle that can use both hydrogen and petrol as fuel, Mazda claimed.

RX-8 Hydrogen RE development program manager, Akihiro Kashiwagi, said: "We're pleased to deliver these hydrogen rotary vehicles for fleet use in these two companies, which are participating in the Japan Hydrogen and Fuel Cell Demonstration Project (JHFC) and are actively engaged in advancing further uses of hydrogen energy.

"And we are looking forward to hearing feedback from our customers about the cars. Mazda will continue its efforts to improve the performance of hydrogen-fueled rotary engine vehicles and do its part to help achieve a more environmentally friendly hydrogen energy society in the future."
