The first Mazda Premacy Hydrogen RE Hybrids available to the public will soon be in the hands of the first lessees. Mazda announced today that it has started commercial leasing of the vehicles, which will be delivered later this year. Unlike the fuel cell-powered Honda FCX Clarity (leases for them started last July), the Premacy uses a hydrogen rotary engine in series configuration with lithium-ion batteries and an electric motor. When the 35 MPa high-pressure tank is filled with H2, the Premacy has a range of about 200 km (124 miles). For drivers worried about range, there's safety in knowing that the rotary engine can burn both hydrogen and gasoline.

The Premacy Hydrogen RE has been road testing since last fall. Mazda has been working hydrogen rotary engines since 1991, when it developed the HR-X engine. In 2006, Mazda began leasing an earlier hydrogen rotary vehicle, the RX-8 Hydrogen RE. More details after the jump.

Mazda Begins Commercial Leasing of World's First Hybrid Rotary Hydrogen Vehicle
- First Mazda Premacy Hydrogen RE Hybrid vehicles registered in Japan -

HIROSHIMA, Japan-Mazda Motor Corporation today commenced commercial leasing of the Mazda Premacy Hydrogen RE Hybrid, a hydrogen hybrid vehicle that offers substantially improved performance thanks to the addition of a hybrid system. Mazda is the world's 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 is Mazda's second hydrogen rotary engine model to be commercialized; the first was Mazda's unique RX-8 Hydrogen RE. The Premacy Hydrogen RE Hybrid's finalized specifications were approved by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on March 5, 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 features a series-type 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, twice the range of the RX-8 Hydrogen RE, and increases the maximum output by approximately 40 percent, to 110 kilowatts. Mazda's latest eco-car features many other forward-looking environmental technologies, including 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 Biotechmaterials.

Based on the Sustainable Zoom-Zoom plan, Mazda is committed to pursuing harmony between driving pleasure and environmental and safety features, and the quest for an advanced Zoom-Zoom world. Mazda aims to offer vehicles that "look inviting to drive, are fun to drive, and make you want to drive them again."
