|Mazda Premacy Hydrogen RE Hybrid|
Mazda will begin commercial leasing of the Premacy Hydrogen RE Hybrid (earlier post) in 2008. The hybrid’s power will be increased by 40%, and it will offer a hydrogen range of 200 km (124 miles), double the 100 km of the first versions of the concept hybrid. Mazda will follow that with an improved hydrogen hybrid system shortly after 2010.
The rollout of the hydrogen-electric hybrids is part of the company’s long-term plan for technology development—“Sustainable Zoom-Zoom”—announced this morning in Tokyo. As part of that effort, Mazda says that it will work closely with Ford.

In the Premacy Hydrogen RE Hybrid, the hydrogen-fueled rotary engine and the 30 kW electric motor are incorporated into a power unit that is transversely mounted at the front of the car in an FF layout. A NiMH battery pack is located under the second-row seats, and a high-capacity hydrogen tank is located in the space that would otherwise be occupied by a third-row seat.
The hydrogen rotary engine has the same hydrogen-gasoline dual-fuel system that is also used in the RX-8 Hydrogen RE.
Mazda is committed to working towards a sustainable future that brings continued happiness and excitement to people in a global society, by developing vehicles that never fail to excite, visually capture the customer's heart and provide a fun driving experience that keeps bringing them back to Mazda.—Seita Kanai, Mazda's director and senior executive officer in charge of R&D
Other key initiatives in the Mazda plan are as follows:
Hydrogen combustion engines.. Mazda will continue researching hydrogen fuel technologies, with particular emphasis on internal combustion engine applications. The company plans an all-new Hydrogen RE with performance equivalent to a 3.0-liter gasoline engine and a range of 400 km. During this development period, Mazda says it will introduce other practical technologies in line with the advancing social infrastructure.
Gasoline engines. Mazda will introduce the Smart Idling Stop System (SISS) (earlier post) in the Japanese market in 2009. The company will introduce an E85 flex-fuel engine to the Northern European market in 2009. And Mazda will upgrade its diesel engine line in the early part of the decade beginning in 2010 to deliver more performance and lower fuel consumption.
Diesel engines. Mazda will evolve its clean diesel engine currently applied in vehicles for Europe, and introduce a new diesel engine that meets Japanese and North American emissions regulations toward the start of the decade beginning in 2010.
Automatic transmissions. Mazda will introduce a new automatic transmission with improved fuel efficiency and performance comparable to that of a manual transmission toward the start of the decade beginning in 2010.
Rotary engines. Mazda will introduce a new generation gasoline rotary engine with enhanced power and fuel efficiency toward the start of the decade beginning in 2010.
Mazda will also work to reduce vehicle weight to improve handling and cut CO2 emissions. For example, it plans a weight reduction of approximately 100 kg for the new Mazda2/Demio due for launch in 2007, as compared to the current model.
Mazda will also expand the application of bioplastics that were developed in collaboration with government, industry and academia. (Earlier post.) Bioplastics will be used in the Premacy Hydrogen RE Hybrid.
