Mazda said that the new SKY-G gasoline engine enables fuel economy equivalent to the current Demio (Mazda2 in markets outside Japan) to be achieved in a vehicle the size of a Mazda Axela, which most us know as the Mazda3.
Next up is the next-generation SKY-D clean diesel engine that offers a high output with reduced fuel economy and low exhaust emissions. The Japanese company says that SKY-D's newly designed engine block reduces mechanical friction to the level of a gasoline engine.
This particular unit also employs piezo injectors, a two-stage turbocharger and other technologies to deliver 20 per cent improvement in fuel economy over the firm's current 2.2-liter diesel engine. With this engine, Mazda says that a vehicle the size of a Atenza (Mazda6) can achieve a fuel economy equivalent to the current Mazda Demio (Mazda2).
Finally, the Japanese maker plans to showcase its newly developed SKY-Drive automatic transmission that contributes to improved fuel economy by approximately five percent compared with the current unit as well as a more direct feel "similar to a dual clutch transmission".
Alongside the new engines and auto gearbox, Mazda's Tokyo Show stand will also host the Japanese premiere of the Kiyora concept city car.
