Mazda Motor Corporation has begun commenced commercial leasing of the Mazda Premacy Hydrogen RE Hybrid (earlier post), a hydrogen hybrid vehicle that offers substantially improved performance due to the addition of a hybrid system. Mazda is the first automobile manufacturer to begin commercial leasing of a hydrogen hybrid vehicle; the first units will be delivered to local government authorities and energy-related companies during 2009.
The Premacy Hydrogen RE Hybrid features a series-hybrid drivetrain, which combines Mazda’s hydrogen rotary engine with an electric motor. The engine output is converted to electricity, which then powers the motor that drives the wheels.
This hybrid system boosts the hydrogen fuel range of the Premacy Hydrogen RE Hybrid to 200 kilometers (124 miles), twice the range of the RX-8 Hydrogen RE, and increases the maximum output by approximately 40%, to 110 kW.
The car features Mazda’s proprietary dual-fuel system, which enables the car to run on gasoline if hydrogen is unavailable, and interior parts made from Mazda’s plant-derived biomaterials.
A Li-ion battery pack provides energy storage, while compressed hydrogen is stored in a 35 MPa (350 bar, 5,000 psi) tank.
The Premacy Hydrogen RE Hybrid’s finalized specifications were approved by Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on 5 March 2009. The first vehicles received their registration numbers from the Hiroshima branch of the Chugoku District Transport Bureau on March 25.
The Premacy Hydrogen RE Hybrid is Mazda’s second hydrogen rotary engine model to be commercialized; the first was Mazda’s RX-8 Hydrogen RE (earlier post).
