Mazda Delivers First Premacy Hydrogen Rotary Engined Hybrid
Submitted by Berny Herrera on Tuesday, May 26, 2009 - 4:30pm

HIROSHIMA, Japan—Mazda Motor Corporation today delivered the first Mazda Premacy Hydrogen RE Hybrid to Iwatani Corporation, an energy development company based in Japan. The Premacy Hydrogen RE Hybrid is Mazda’s latest hydrogen rotary engine (RE) vehicle which uses hydrogen as a fuel and features a unique hybrid system. The Mazda Premacy Hydrogen RE Hybrid can run on both hydrogen and gasoline thanks to a dual-fuel system that was developed for the current RX-8 Hydrogen RE. The addition of a new hybrid system significantly enhances the vehicle’s performance and contributes to its increased hydrogen fuel range of 200 kilometers; double that of the RX-8 Hydrogen RE. The Premacy Hydrogen RE Hybrid is the second hydrogen rotary engine vehicle to be leased to Iwatani Corporation, following an RX-8 Hydrogen RE that was delivered in March 2006. The new model will be used for business purposes at the company’s offices in Western Japan, before being located at the Japan Hydrogen & Fuel Cell Demonstration Project’s (JHFC) Kansai Airport Hydrogen Station, where it will be used at the Kansai International Airport in Osaka and for a variety of other purposes. Mazda Premacy Hydrogen RE Hybrid (Iwatani Corporation version)Mazda Premacy Hydrogen RE Hybrid (Iwatani Corporation version) Akihiro Kashiwagi, Mazda’s program manager in charge of hydrogen RE development, said, “Mazda is delighted to deliver our newest hydrogen rotary engine vehicle to Iwatani, which has been engaged in advancing the further uses of hydrogen energy for many years. Mazda will use the feedback we receive from Iwatani to further improve the performance of hydrogen-fueled rotary engine vehicles as we wish to do our part to achieve a hydrogen energy society in the future.” Based on its Sustainable Zoom-Zoom plan, Mazda is committed to pursuing harmony between driving pleasure and environmental and safety features. Mazda constantly strives to offer vehicles that “look inviting to drive, are fun to drive, and make you want to drive them again.” Main specifications of the Mazda Premacy Hydrogen RE HybridBase model:Mazda PremacyOverall length:4,565 mmOverall width:1,745 mmOverall height:1,620 mmEngine:Mazda’s hydrogen rotary engine (with dual-fuel system)Motor:Alternating current synchronous motorMaximum output:  110 kWGenerator:Alternating current synchronous generatorBattery:Lithium-ion (Li-ion)Seating capacity:FiveFuel:Hydrogen and gasolineHydrogen tank:35 MPa high-pressure tank History of Mazda’s hydrogen vehicle development1991  Developed first hydrogen rotary engine vehicle, HR-X1992Conducted test drive of golf cart equipped with fuel cell1993Developed second hydrogen rotary engine vehicle, HR-X2Developed MX-5 test vehicle equipped with hydrogen rotary engine1995Conducted Japan’s first public road tests of a hydrogen rotary engine vehicle, Capella Cargo.1997Developed Demio FC-EV2001Developed Premacy FC-EV, conducted first public road test in Japan2003Announced RX-8 hydrogen rotary engine development2004Received MLIT approval for public road testing of RX-8 Hydrogen RE2006Started commercial leasing of RX-8 Hydrogen RE in Japan (eight models have been delivered to date)2007Signed agreement to provide RX-8 Hydrogen REs to Hynor, a Norwegian national transportation project2008Commenced public road tests in Norway with RX-8 Hydrogen RE validation vehicle2009Commenced commercial leasing of Premacy Hydrogen RE Hybrid in Japan For more information on Mazda’s hydrogen rotary engine vehicles, please visit:

In case anyone didn't know. The rotary engine in the Premacy is front wheel drive. The last time Mazda did a front wheel drive rotary was back in the 70's, in a 2 door rx4 looking coupe, I think.(Correct me if I'm wrong Dan)

Will Mazda start adding fuel efficient rotaries in their front wheel drive platforms?
Who knows, I'd be okay with it as long as the Rx7 and Rx8 remain RWD in the future.

Actually, the FWD rotary was never imported to the US. The 69-72 Luce was powered by the odd 13a engine, it was a longitudinally mounted engine, that sits way far front of the front wheels, the tranny behind it had the drive axels sticking out of the front area, just behind the bell housing IIRC.

The Luce is exceedingly rare. I think there may only be 2-3 of them in the states, and maybe a couple hundred or less left in Japan.

Mazda USA obtained one of these, and had it at SevenStock a few years ago. It is a strange beast.

Yeah I remember seeing a clip on autoline detroit, when they looked inside Mazda Usa's garage of collections. Did they start it up at 7stock?

Thanks for the link Berny.

I found some info about the LUCE @:

Mazda did a FWD first in the LUCE Coupe in the early '70s with the 13A motor. For more info on the engine/drivetrain layout of this new PREMACY (MAZDA5) set-up see:
