Mazda's next-generation of engines and automatic transmissions are at the Tokyo motor show.
The Japanese firm is exhibiting its Mazda SKY-G direct-injection petrol engine, its Mazda SKY-D clean diesel engine and the Mazda SKY Drive high-efficiency automatic transmission. It's also showing its Kiyora concept car in its home country for the first time.
The Mazda SKY-G is a direct-injection petrol engine with significantly improved fuel economy and power output due to enhanced thermal efficiency. It has been designed to reduce mechanical friction and achieve an optimal air-fuel mix, with fuel economy and torque improved by approximately 15 per cent compared to Mazda’s current 2.0-litre engine.
This equates to the fuel economy seen in a Mazda 2 to be achieved by a Mazda 3.
The Mazda SKY-D engine reduces mechanical friction to the level of a petrol engine. By employing piezo injectors, a two-stage turbocharger and other technologies, fuel economy becomes around 20 per cent better than the current 2.2-litre diesel engine. This equates to fuel economy of the Mazda 2 being achieved in the Mazda 6.
