2.0L DI gasoline ‘SKY-G’ and 2.2L diesel engine ‘SKY-D’ engines.
Mazda will showcase the world premiere of its next-generation engine lineup and automatic transmissions at the 41st Tokyo Motor Show.
Mazda’s theme for the 2009 Tokyo Motor Show is “The Mazda SKY concept—Providing driving pleasure plus environmental and safety features for all customers!” Under the headings of “Today,” “Tomorrow” and “The Future,” Mazda will display advanced technologies designed to improve the average fuel economy of Mazda vehicles sold globally 30 percent by 2015 compared to 2008 levels. This is one of the goals of Mazda’s long-term vision for Sustainable Zoom-Zoom.
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 Mazda2 from the current Mazda3.
Mazda SKY-D diesel 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 2.2L diesel. Mazda has achieved fuel economy equivalent to the current Mazda Demio from a vehicle the size of the Mazda6.
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.

The Mazda Kiyora, a next-generation compact concept car imbued with Mazda’s fun-to-drive character, will make its Japanese debut at the Tokyo show. Featuring the next-generation Mazda SKY concept powertrain technologies and comprehensive advancements in weight reduction, the Kiyora achieves outstanding fuel economy of 75 mpgUS on the Japan 10-15 or approximately 42 mpgUS combined on the 08 EPA?
Alongside the SKY concept exhibits, Mazda will also feature a “Today’s Technologies” exhibit that includes i-stop, a unique idling stop system that was introduced with the all-new Mazda Axela (known as the Mazda3 overseas). “Future Technologies” will showcase the advanced Mazda Premacy Hydrogen RE Hybrid, with its hydrogen-powered rotary engine, and various vehicle technologies under development as part of Mazda’s drive to realize an accident-free and safe motorized society.
