The Premacy Hydrogen RE Hybrid – Mazda’s Rotary Technology Gets New Wheels

Mazda announced today their second hydrogen rotary vehicle following the RX-8 Hydrogen RE, delivered to The Iwatani Corporation, an energy company in Japan. The Premacy Hydrogen RE Hybrid is twice as efficient than the RX-8 Hydrogen RE, converting hydrogen combustion energy into electric energy to drive the motor 400 km (124 miles) with zero emissions.

The Premacy, like the RX-8, uses a dual-fuel system for both hydrogen and gasoline, but on a hybrid system that allows for a better range and boost in power. Iwantani will test the Premacy for commercial leasing, and the feedback provided will help Mazda make improvements on this singular type of rotary engine.

Because of the characteristics of Mazda’s original rotary engine, the RENESIS hydrogen rotary engine was developed at low cost. This system draws in air from a side port and injects hydrogen directly into the intake chamber with an electronically-controlled hydrogen gas injector installed on the top of the rotor housing.
