Mazda Kiyora Concept set to debut at the Tokyo Motor Show – Click above for high-res image gallery

Mazda has just dropped off a bunch of info about their next-generation clean engines that will be officially unveiled at the Tokyo Motor Show in October, and we have two words for you: Direct and Diesel. Along with its next-gen 'Mazda SKY Drive' high-efficiency automatic transmissions, visitors to the at 41st Tokyo Motor Show will get to see the 'Mazda SKY-G' direct injection gas engine and the 'Mazda SKY-D' clean diesel engine. The house of Zoom-Zoom is hoping to use these advanced technologies to boost their corporate average fuel economy by a whopping 30% between 2008 and 2015.

In typical Mazda fashion, they want everyone to know that they haven't given up on driving excitement in their move to more eco-friendly fare – the Japanese automaker is out to prove that 'fun' and 'green' don't have to be mutually exclusive terms. The Mazda SKY display area will be broken into "Technologies for Today, Tomorrow and The Future." The Today area will show off things like i-stop, the idle start-stop feature that debuted on the 2010 Mazda3. The Future area will host the rotary-powered Mazda Premacy Hydrogen RE Hybrid, among other things. But the one we're really waiting to see is the updated Mazda Kiyora concept.

The Kiyora is a lightweight concept first shown in Paris last year. For Tokyo it's powered by a new 1.3-liter direct injection engine. It will travel 32 kilometers per liter of fuel (under Japan's 10-15 mode test cycle) – that's 75 mpg – and promises lots of smiles per gallon as well. Besides that new SKY engine, the Kiyora will also feature the new Mazda SKY-Drive six-speed automatic transmission, i-stop, regenerative braking, and super-slick aerodynamics. It also weighs at least 100 kg less than any other car in the company's current lineup. Follow the jump for more details from the official press release and check out the high-res gallery below.

Summary of major exhibits
Mazda Kiyora

The Mazda Kiyora is a compact concept car that is both extremely eco-friendly and fun-to-drive due to the combination of Mazda's next-generation direct injection Mazda SKY-G 1.3 engine and new compact and lightweight six-speed Mazda SKY-Drive automatic transmission. The Kiyora achieves excellent fuel economy figures of 32 kilometers per liter (under Japan's 10-15 mode test cycle) aided by Mazda's unique i-stop idling stop system, regenerative braking, and advanced aerodynamics around a compact body that is 100 kilograms lighter than Mazda's current mass production model in the same segment.

Mazda Premacy Hydrogen RE Hybrid

In March 2009, Mazda began leasing the Mazda Premacy Hydrogen RE Hybrid to Japanese government authorities and energy-related organizations. It features a unique series hybrid system, consisting of a hydrogen rotary engine connected to a generator that powers an electric motor. This advanced powertrain enables the Premacy Hydrogen RE Hybrid to achieve a hydrogen-fueled driving range of 200 kilometers. The vehicle also employs Mazda's plant-derived Biotechmaterials*, reflecting initiatives to realize use of non-petroleum-based resources and reduce CO2 emissions.

* Biotechmaterials is the collective name for plant-based materials that Mazda is developing, including bioplastic and biofabric.

Next-generation direct injection Mazda SKY-G gasoline engine

Mazda SKY-G is a next-generation direct injection gasoline engine with significantly improved fuel economy and output performance due to enhanced thermal efficiency. The engine block is newly designed to reduce mechanical friction and achieve an optimal air-fuel mix, and a direct fuel injection system is employed due to the wide variety of spray profiles that are possible, enabling the maximum expansion ratio to be achieved. Specifically, fuel economy and torque are improved by approximately 15 percent compared to Mazda's current 2.0-liter engine. This was achieved by adopting next-generation fuel injectors and a highly functional variable valve timing mechanism. The engine enables fuel economy equivalent to the current Mazda Demio (known as the Mazda2 overseas) to be achieved in a vehicle the size of a Mazda Axela (Mazda3).

Next-generation clean diesel Mazda SKY-D engine

Mazda's new SKY-D clean diesel engine boasts high fuel economy and output performance as well as low exhaust emissions. The newly designed engine block reduces mechanical friction to the level of a gasoline engine. By optimizing the pressure and temperature in the cylinders, the shape of combustion chambers, and the fuel injection rate, combustion begins at the best timing in terms of thermal efficiency. Specifically, by employing piezo injectors, a two-stage turbocharger and other technologies, fuel economy becomes approximately 20 percent better than the current 2.2-liter diesel engine. Mazda has achieved fuel economy equivalent to the current Mazda Demio (known overseas as the Mazda2) in a vehicle the size of a Mazda Atenza (Mazda6).

Next-generation Mazda SKY-Drive automatic transmission

Mazda's next-generation SKY-Drive automatic transmission is highly efficient, contributing to substantially improved fuel economy and a more direct feel compared with the current unit. It improves fuel economy by approximately five percent, due to a complete redesign that significantly reduces mechanical friction, a revised torque converter and clutch with minimized slip, and an optimized lock-up mechanism. A rapid clutch action was achieved by identifying the minimum amount of fluid necessary. This also helped to realize a direct feel similar to a dual clutch transmission.

      Remember that part, early in the "Men in Black" film, where the alien wearing Edgar's skin pulls up on his hair and stretches his face upward?

      That's what this car reminds me of.
      • 5 Years Ago
      Very good and welcome news.
      • 5 Years Ago
      But, it looks like Dori the fish from Finding Nemo... Hahahaha...
      • 5 Years Ago
      the Kiyora make a nice city car if it really got real world mileage like that.

      This reminds me of the Predator. the mask and all that besides the dreads.
      • 5 Years Ago
      The mechanical news is pretty sweet.
      The concept? I literally have no idea what to think.
      • 5 Years Ago
      How about RX-7 successor?
      • 5 Years Ago
      Is it just me or does the front look like somebody wrapped a piece of thick plastic over the front of a Mazda3?
      • 5 Years Ago
      I wonder about the manufacturing feasibility of the car's styling. I mean, wow, love the futuristic look, but don't go yanking my chain again with another wildly improbable concept car that no one could build for a reasonable price. I want the future and I want it now. Not some watered down version of the dream.
      • 5 Years Ago
      I thought the rumor was they were going to show the next gen RX7, 8, 9 or whatever concept with the DI 16x Rotary engine? Or is that going to be for a different show?
        • 5 Years Ago
        I hear you. I've been waiting all year for Tokyo just for that reason.

        Hopefully they're trying to lower their CAFE just to make room for the 16X... *fingers crossed*

        I have to say, I wasn't impressed with that little concept at first, but it's already growing on me.
        • 5 Years Ago
        That is the rumour. It just makes sense too since what other auto show would they reveal it at? If they don't reveal it in Tokyo, I think they're going to have a LOT of rotary fans that are pretty choked. The RX-8 was great but it wasn't what every rotary enthusiast was screaming for: 2 seats, big power, more torque. One could add turbo onto that list but I think everyone has realized a turbo rotary drinks fuel like a V8. The 16x needs a home badly at this point...
      • 5 Years Ago
      How about a concept from Mazda that has a chance at production?

      BTW: This design is hardly futuristic. It's just another non-practical styling exercise that should stay in the design studio.
        • 5 Years Ago
        Still haven't gotten over your mom refusing to hang your art projects on the fridge, huh?
        • 5 Years Ago
        I've grown to understand that hanging nude photos of your mother on our fridge would have been inappropriate.
        • 5 Years Ago
        ZING!
      • 5 Years Ago
      Well this is good an all but judging from the end result that we have seen from the Kizashi concept we can probably expect the end result to look like a car that is on par with the looks of a VW Rabbit or having some styling borrowed from some other current hatchback.
        • 5 Years Ago
        I dunno, the mazda 2 looks pretty cool. though the new golf and polo look better than their predecessors so looking goflike might not be that bad. The new 3's finally grown on me, making the previous generation look very dated.

        Anywho, it's great to see automakers finally joining VW/Audi in numbers when it comes to direct injection and more advanced diesel offerings.
