OFFICIAL: Mazda SENKU at the 39th Tokyo Motor Show
Submitted by Dan Mazzella on Tuesday, October 4, 2005 - 9:37am

Mazda Motor Corporation has announced that it will showcase the world premiere of the Mazda SENKU concept vehicle, as well as the Japan debut of the Mazda MX-Crossport concept, at the 39th Tokyo Motor Show, to be held at Makuhari Messe, Chiba prefecture, from Wednesday, October 19 through Sunday, November 6, 2005.

Joining them on the Mazda stand will be the all-new Mazda MPV, soon to be launched in Japan. Also exhibited at the Tokyo show will be the Mazda Premacy Hydrogen RE Hybrid concept vehicle—offering both Zoom-Zoom driving pleasure and outstanding eco-friendliness - and the next-generation MZR 2.3 DISI Turbo and Advanced Driver-Support Technologies.

Mazda will hold a press briefing at the Mazda stand in the West Hall, Makuhari Messe from 10:00 to 10:20 a.m. on Wednesday, October 19.

Mazda will display a wide variety of vehicles and technologies that demonstrate its product-led growth to visitors, highlighting the progress of Mazda Momentum, its mid-term corporate management plan that was launched in November 2004.

Mazda SENKU, 'a four-seater rotary sports car for adults', is a concept car that reflects a new direction for four-seater rotary sports cars designed with mature drivers in mind.

The concept clearly demonstrates how Mazda continues to offer new and unique Zoom-Zoom driving qualities in the face of increasing environmental and safety requirements and diversifying customer demands posed by societal changes.

Mazda MX-Crossport—an entirely new breed of vehicle that combines the merits of a sports car and an SUV—was first introduced to the public in January at the 2005 North America International Auto Show in Detroit. The Tokyo Motor Show marks its debut in Japan. The Mazda MX-Crossport indicates a direction that Mazda's future products could take as it further expands its lineup of new generation products.

The Mazda Premacy Hydrogen RE (rotary engine) Hybrid concept features a hybrid power unit that combines a dual-fuel, hydrogen/gasoline rotary engine with an electric motor. The power unit is transversely mounted at the front in a front-wheel drive layout. The development team aimed to produce a vehicle with outstanding driving and environmental performance along with a comfortable, roomy interior.

Other exhibits include a Mazda RX-8 equipped with the hydrogen RE engine that is viable for practical uses, with plans for commercial leasing in the future. Also on exhibit will be the next-generation MZR 2.3 DISI Turbo engine with direct injection that achieves clean, powerful performance; the Smart Idling Stop System which eliminates the need for an electric starter motor, and delivers quiet and quick starting; and Advanced Driver-Support Technologies that incorporates intelligent transport systems. Mazda is developing unique technologies to create vehicles that combine care for the environment while still retaining the Zoom-Zoom spirit. Test rides in the Mazda RX-8 Hydrogen RE are available at the Clean Energy Vehicle Test Ride event site.

The pursuit of dreams and confident self-expression are becoming more widespread among mature drivers. Mazda SENKU, 'a four-seater rotary sports car for adults', offers a radical new departure in satisfying these desires. Its overarching design concept is "sharpness and mellowness," and these contradictory factors are cleverly integrated to create a next generation design standard. The features include an ultra long wheelbase, minimal overhangs, a unique "floating" appearance supported by large tires, a smoothly dignified shape devoid of all ornamentation, and large "flying wing" electric powered sliding doors. These elements come together in a revolutionary coupe form that is both dynamic and supremely elegant. In the cabin, personal space was designed to give priority to the people seated in the front seats, and interior trim was executed in supple, high quality leather.

Located between the front and rear axles is the next generation 13B DI direct injection gasoline rotary engine with a hybrid unit.

This direct injection RE hybrid achieves high power output and lower fuel consumption along with the ideal 50:50 front/rear weight distribution and a low center of gravity, characteristic of Mazda sports cars, providing fun and dynamic driving.

The name "Senku" is a Japanese term meaning "pioneer", depicting Mazda's spirit of pursuing unique and exciting ventures - such as the rotary engine.

Mazda Premacy Hydrogen RE Hybrid
The power unit for the Mazda Premacy Hydrogen RE Hybrid concept incorporates a hydrogen rotary engine, offering dual fuel driving with hydrogen and gasoline, in tandem with an electric motor. The hydrogen rotary engine and the hybrid unit are transversely mounted at the front of the car in a FF layout, with the high voltage battery located beneath the second row seats and the high pressure hydrogen tank beside the third row seat. This efficient packaging allows the Hydrogen RE based hybrid system to achieve outstanding environmental and driving performance as well as a comfortably roomy interior.
