The Mazda RX-8 Hydrogen RE is a 2003 bi-fuel version of the RX-8 sports car, in which the twin-rotor wankel rotary engine is configured to run on either hydrogen or gasoline. This is the fifth Mazda vehicle to be fitted with a hydrogen wankel rotary engine.
Specifications
The hydrogen tank is made up of aluminum and carbon fibre and has a capacity of 110 liters at 350 blolar stores up to 2.4 kilograms of hydrogen and is fitted in addition to the 61-liter gasoline tank. The car can be switched from gasoline to hydrogen mode using a button in the cabin.[1] The Hydrogen tank takes up most of the RX-8s trunk space and all the hydrogen components weigh in at 187 lbs in total. Running in hydrogen mode, it produces no emissions other than water vapor and has a range of around 100 km (62 mi).[2] In 2005, Mazda obtained street approval for this vehicle. The following year, the first vehicles were leased to customers in Idemitsu and Iwatani at a price of 420,000 JPY per month.[3] In November 2007, Mazda announced the delivery of 30 RX-8 HRE to the Norway hydrogen project Hynor.[4]
