Mazda’s latest hydrogen hybrid to debut at Tokyo Motor Show
According to the automaker, the Premacy features several improvements—including better acceleration and an extended hydrogen-fueled range—over the Mazda RX-8 Hydrogen RE.
The Premacy is equipped with a transverse hydrogen rotary engine, featuring Mazda’s hydrogen/gasoline dual-fuel system. The hybrid system efficiently converts energy from hydrogen combustion to electricity and uses it to power the motor, the automaker said.
Compared to the Mazda RX-8 Hydrogen RE, the Premacy yields 40 percent better output, according to Mazda, resulting in better acceleration and an extended hydrogen-fueled range of about 200 kilometers—twice that of the RX-8 Hydrogen RE. The Premacy also features increased seating capacity—it can accommodate up to five adults, Mazda noted—and more luggage space.
According to Mazda, the automaker changed the hydrogen rotary engine from a longitudinal to a transverse layout and improved the vehicle’s intake/exhaust resistance and combustion efficiency to yield high output across a wide range of engine speeds.
“Thanks to progress in electric-drive technology, the system realizes high energy efficiency and a quick response allied with low fuel consumption,” the company said in a news release. “Acceleration kicks in the instant you hit the accelerator, creating a direct feeling of power.”
Interior features biofabrics
On another green note, Mazda said that the Premacy’s interior seat covers and door trim are made with what the automaker claims is the world’s first biofabric made with completely plant-derived fibers. Mazda “Biotechmaterial 2” is being used to accelerate research and development for commercial use, the automaker said.
Mazda developed the biofabric in collaboration with Teijin Ltd. and Teijin Fibers Ltd.
According to Mazda, the flame-retardant biofabric does not contain any oil-based materials and is resistant to abrasion and damage from sunlight.
“Based on this biotechnology, Mazda will strengthen its future research and development on non-food-based materials in consideration of the impact such technologies have on food supplies,” the company said.
The Premacy also will feature a bioplastic—which Mazda developed in 2006—in the vehicle’s instrument panel and other interior fittings.
Mazda said that leasing of the Premacy will begin in 2008.
