Today, Mazda announced their 2007 Tokyo Autoshow lineup, including the far-out coupe concept the TAIKI, and the next generation Rotary Engine: the 16X. The Mazda Taiki continues the evolution of the Nagare design theme, following in the footsteps of the Mazda Nagare, Mazda Ryuga, and Mazda Hakaze concept vehicles. As the fourth in the series, Mazda Taiki further advances and refines the theme through a fusion of the Nagare (flow) design concept and real-world technologies, such as a next-generation rotary engine and enhanced aerodynamic performance. Mazda Taiki sets a new ideal for the front-engine rear-drive sports car of the future.

Next Generation RENESIS (Rotary Engine 16X)

In developing the next-generation RENESIS, Mazda made a thoroughgoing revision of engine dimensions including the trochoid rotor housing, adopting a longer stroke and larger displacement of 1600cc (800cc x 2) aimed to raise thermal efficiency and boost torque at all engine speeds. By employing the Hydrogen RE design policy of a direct injection system and aluminum side housing, as well as various other measures, we are further promoting the rotary engine’s merits of light weight and compact size.





Mazda Taiki reflects one possible direction for a future generation of Mazda sports cars aimed at helping create a sustainable society. The fourth concept car in the Nagare design series, Mazda Taiki further evolves the “flow” theme to establish a breathtaking presence that clearly distinguishes it as the next in the series, and which visually expresses the atmosphere – called taiki in Japanese – that wraps the Earth in its protective mantle.

The basic proportions begin with the stretched coupe form of a front-engine rear-wheel-drive layout, the short overhangs, and the liberating feel of an all-glass canopy. The challenge to create “a design that visually expresses the flow of air” was inspired by the image of a pair of Hagoromo – the flowing robes that enable a celestial maiden to fly in Japanese legend – floating down from the sky. Inspired by Japanese koinobori – the decorative “climbing carp streamers”– the notion of creating an Air-tube became the concept word for the interior design. In accordance, from the dashboard and seats down to the door trim, the interior space creates the dynamic sensation that the flow of the wind is being visually depicted. Centering around the performance rotary engine sports packaging that is synonymous with the Mazda name, technologies introduced for the Mazda Taiki include the next-generation RENESIS (rotary engine 16X), which sets new standards for environmental and driving performance, a front-engine rear-drive layout, a unique 2-seat configuration, and Mazda’s rotary sports package, which conveys an image of lightness. The effect integrates the design theme perfectly to realize outstanding aerodynamic performance.

Also shown is the New Mazda Premacy Hydrogen RE Hybrid


Compared with the Mazda RX-8 Hydrogen RE, the new Premacy Hydrogen RE Hybrid yields 40% better output, resulting in enhanced acceleration performance and an extended hydrogen-fueled range of about 200km, or twice that of the RX-8 Hydrogen RE. Seating capacity is also increased to give accommodation for five adults along with greater luggage space. The hydrogen rotary engine is changed from a longitudinal to a transverse layout and its intake/exhaust resistance and combustion efficiency are improved to yield high output across a wide range of engine speeds. The hybrid system employed for the hydrogen rotary engine efficiently converts energy from hydrogen combustion into electricity that powers the electric motor. Thanks to progress in electric drive technology, the system realizes high energy-efficiency and a quick response allied with low fuel consumption. Acceleration kicks in the instant you hit the accelerator, creating a direct feeling of power.
