Taiki Rotary Sportscar Concept to be unveiled at Tokyo Auto Show
Just released from Mazda press room (edited to contain only information about the Taiki concept):
and then a bit more info on the next-gen RENESIS engine:
see attached for teaser pics of the Taiki concept
The all-new Mazda Atenza - soon to be introduced in Japan, the Mazda Taiki concept car, equipped with a next-generation rotary engine, the new Mazda Premacy Hydrogen RE Hybrid, a series of future-oriented powertrains, and a variety of environmental and safety technologies will be revealed by Mazda Motor Corporation (Mazda) at the 40th Tokyo Motor Show*1 in October 2007.
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.
Mazda Taiki
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.

and then a bit more info on the next-gen RENESIS engine:
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.

its a concept!!!
with those tire widths, it'll have problem with 100hp.

Am I the only one that doesn't care how ugly the car is when you put it up next to the fact that mazda has a concept out that is a 2 door coupe (as opposed to a 4 door coupe), which looks like it has only 2 seats, extremely aggressive styling, a new rotary (16X, that just sounds weird) that sounds like it might be all aluminum?
I mean seriously... what does that say to you?
but yes.. the rear end of that car is retarded.

that's one weird looking concept.
which is OK, since cost will eliminate any chance of actually producing it as shown.
but a 1.6 rotary in a RWD 2 seater? Count me in.
Hydrogen adds an interesting twist - emissions have always plagued rotaries. It's one of the reasons we burn gas outside the combustion chamber and get poor gas mileage. H2 burns clean - might just work, but I wonder if they can actually pull it off anytime in the near future.
more torque? Count me in again.
not sure there's a H2 station in my area yet...

Heard from a employee with MNAO (who shall remain nameless) that the engine "can" make 300hp. Keep in mind that is probably without any power robbing devices on the car such as alternator, a/c, etc and probably tuned with little account for emissions. What the car will do with everything on it will most likely be less than that. 270-280 is a reasonable guess. As far as torque goes, and this is only speculation on my part, it will probably be somewhere around the 190-200 ft lb mark. I base this on a very simple scaling. The Renesis at 160 cu in produces around 160 ft lbs of torque or so. give or take a few. Even the 13B's could do about that. The new engine is roughly 190 cu in or so which should put it's torque proportionately higher at the 190-200 mark. You'll feel it.
Also heard some interesting development information that the rotary designers were given a very strict timetable in order to meet their emissions targets. The date was the end of September. They apparently came in just under the wire on that one. If they didn't meet it, the project wasn't supposed to get the go ahead. Keep in mind we are talking about emissions standards for 2010-2011 and beyond and it has to meet everyone's standards. The direct injection is what makes it all possible. I'm excited. Let's see it.
