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 Mazda Kiyora concept. The Kiyora is a lightweight concept 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.
