|Hydrogen RE with Iwatani International badging.|
Mazda Motor Corporation has delivered one RX-8 Hydrogen RE vehicle each to its first two corporate customers for this model: Idemitsu Kosan Co., Ltd. in Tokyo, and Iwatani International Corporation in Osaka, Japan. (Earlier post.) This marks the first commercial leasing of a hydrogen-gasoline dual fuel vehicle.
The RX-8 Hydrogen RE is equipped with a rotary engine, and features a dual-fuel system that allows the driver to select either hydrogen or gasoline with the flick of a switch. The vehicles that have been leased to these first two corporate fleet customers are based on the original body design but with specially added company decals for each customer’s use.
We’re pleased to deliver these hydrogen rotary engine 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.—Akihiro Kashiwagi, RX-8 Hydrogen RE development program manager
The hydrogen range of the vehicle is limited: 100 km (62.1 miles). The car stores 110 liters of hydrogen compressed at 35 Mpa (350 bar).
The RENESIS Hydrogen RE incorporates an electronically controlled hydrogen gas injector system. The system draws air from the side port during the intake cycle and uses dual hydrogen injectors in each of the engine’s twin rotor housings to directly inject hydrogen into the intake chambers.
For future versions of the rotary hydrogen cars, Mazda plans to incorporate the RENESIS hydrogen rotary engine with the emerging Mazda Hybrid System and an electric-motor-assisted turbocharger to enhance efficiency as well as the driving experience.
