Mazda to Exhibit RX-EVOLV Concept Car with New Rotary Engine and others

-Mazda's message at the Tokyo Motor Show is "New Ideas that Stir Your Emotions"-

Mazda Motor Corporation will exhibit concept cars including the RX-EVOLV equipped with a new rotary engine and present new technologies based on the message "New Ideas that Stir Your Emotions" at the 33rd Tokyo Motor Show (*). It will be held at Chiba's Makuhari Messe Convention Center from October 23 (Saturday) to November 3 (Wednesday).

As the leading concept car, the RX-EVOLV expresses the completely new four-seater sports car world that embodies Mazda's brand personality: "stylish", "insightful", and "spirited". The use of the newly developed, compact RENESIS(**) rotary engine allows a spacious interior roomy enough for four adults to enjoy sports driving without any compromise in the same body size as the RX-7.

Mazda will show several other concept cars as well, including the NEOSPACE, developed as a functional compact car, and the NEXTOURER, a new-generation touring sedan.

In addition, technological exhibits on environmental and safety topics will be presented. These include the DEMIO FCEV fuel cell electric vehicle, the Mazda DIREC-G direct fuel injection gasoline engine, the Mazda DIREC-D direct fuel injection diesel engine, the Mazda Toroidal CVT next-generation transmission, the Safety Active Seat, and the Smart Airbag.

(*)This is the first "Passenger Car and Motorcycle Show" after moving the "Commercial Vehicle" section to a separate show. Mazda will hold a press briefing at the Mazda booth in the East Hall on Wednesday, October 20, from 10:00 to 10:25.
(**)The "RENESIS" name encapsulates the feeling of "new" taken from the expressions "Re" or "new", and "Genesis."

Outline of Main Exhibits

  1. Concept Cars
    RX-EVOLV
    Mazda has consistently built sports cars that are "fun to drive." To continue this tradition, the RX-EVOLV incorporates the five elements of appropriate body size, a consistent application of thorough weight reduction, a balanced 50-50 front-rear weight distribution, a FR layout, and a low inertial yaw, which together form what the company calls "Mazda Spirited DNA". The newly developed RENESIS rotary engine makes it possible to satisfy all of these elements. The RENESIS demonstrates a maximum power output of 280 PS/9,000rpm and maximum torque of 23.0 kg-m/8,000 rpm, even with the use of a natural-intake engine. The RENESIS also meets the needs of a new-millennium engine by meeting Japanese Low Emission Vehicle (LEV) standards, enhancing fuel economy at all operational speeds, from idling to high-speed driving. The RX-EVOLV is brimming with a most of new features including technology to change the engine performance in relation to the driver's skill.

    NEOSPACE
    The NEOSPACE is a "Functional Compact Car" which has innovative features to match the versatility of customer lifestyles.
    Within an easy-to-handle body size, the NEOSPACE provides a spacious interior in which four adults can ride in comfort. Moreover, there are insightful new features for more effective use of the interior. A "FreeStyle Door System" without a B-pillar makes entry and exit easy from the vehicle, rear NEOSPACE KARAKURI seats can be pushed back and stored in the sunken floor, and a sloping tale gate makes loading and unloading of luggage easy.

    NEXTOURER
    The NEXTOURER is a new generation touring concept car, which blends high-speed touring performance of a luxury sedan with the functionality of an SUV.
    The Flexible Package Board provides superb functionality to create a versatile space,The Active Height Control System provides the optimum seating position and vehicle height. Together with high performance, the NEXTOURER has a high level of safety with advanced interface functions exemplified by ITS (Intelligent Transport Systems), the Intelligent Headlamp System and ITS warning system. The result is both the safety and the comfort you would expect in a high-quality touring car.

  2. Technological Exhibits
    DEMIO FCEV
    The DEMIO FCEV employs newly developed fuel cell stacks generating a maximum output of 50 kW in total and a newly developed fuel cell drive system. Together, these enable the vehicle to reach a top speed of 140 km/h, 50 km/h faster than previously developed DEMIO FCEV.

    In April of 1998 Mazda joined a new alliance with Ford Motor Corporation, DaimlerChrysler, and Ballard Power Systems Inc. for the development of fuel cell technology. Through the new alliance, Mazda has continued to work on research and development aimed at the realization of fuel cell technology. The DEMIO FCEV incorporates a fuel cell system developed by the alliance.

    Mazda DIREC-G
    The Mazda DIREC-G is a 1,498cc-displacement direct injection gasoline engine. Fitting with a S-VT (Sequential-Valve Timing) consecutive-phase variable valve-timing system, the DIREC-G engine provides higher output and torque, while at the same time decreasing fuel consumption and carbon dioxide (CO2) emissions. To deal with the nitrogen oxides (NOx) which arise as a byproduct of stratified combustion, the use of a consecutive-phase variable valve-timing mechanism and an exhaust gas re-circulation system, as well as the newly developed NOx reduction catalyst, dramatically reduces NOx emissions.

    Mazda DIREC-D
    Mazda's newly developed direct injection turbo diesel engine, the Mazda DIREC-D, is a small and lightweight engine integrated with a common rail plenum fuel injection system and a 4-way catalyst. Its 1,998cc displacement makes it an ideal powerplant for small passenger cars.
    Compared to the previous type, output is increased by about 40%, while fuel economy is also improved. Significant reductions in NOx and CO2 enable it to meet the EURO-4 emissions standard in Europe. Black smoke emissions, noise and vibration have also been dramatically reduced.

    Mazda Toroidal CVT
    The Mazda Toroidal CVT(continuously variable transmission) is a highly efficient, lightweight and compact next-generation transmission. It can also handle high engine output.
    The combination of the half-toroidal CVT form with a neutral geared starting system further enhances the overall efficiency and compactness for front wheel drive vehicle. The system delivers superb response, quiet operation and excellent fuel economy at the same time. To illustrate just how economical this system can be, the transmission was combined with a 3.0-litter engine instead of the usual four-speed automatic and about 20% improvement in fuel economy was achieved in 10·15 mode.

    Safety Active Seat
    The Safety Active Seat is a new technology to reduce whiplash injury. In a rear collision, the headrest moves forward to quickly support the head of the passenger. This reduces sharp movement of the neck immediately after a collision, greatly reducing the stress to this region. In addition the Safety Active Seat uses a seatbelt system which predicts rear-end collisions before they occur and then firmly restrains passenger's' bodies. Before the imminent collision, the system draws the head region closer to the headrest, and keeps movement of the head and chest to a minimum by putting pressure on the muscles at the base of the neck, thereby decreasing whiplash injuries.

    Smart Airbag
    The Smart Airbag uses a two-stage inflator. It monitors the collision force, and deploys the airbag in two stages in relation to the impact force in a collision. In low-speed collisions, inflation of the air bag is 30 percent less than that applied during high-speed collisions, thereby reducing the impact force on the passengers.
