Next generation powertrains

Fuel economy and torque increased by up to 15% Next-generation direct injection gasoline engine“Mazda SKY-G”*

Generally speaking, diesel engines already deliver relatively good fuel economy. However, improving fuel efficiency even further while simultaneously reducing nitrogen oxide (NOx) and Particulate Matter (PM) emissions is a major technical challenge that has, until now, been seen as extremely difficult. To break through this barrier, we aimed to achieve ideal fuel combustion in the development of the next-generation “Mazda SKY-D”* diesel engine. The result of our efforts is clean emissions to meet anticipated strict future regulations, along with a 20% improvement in fuel economy compared with the current diesel turbo engine, and a substantial increase in low-and high-end torque for enhanced overtaking acceleration.

Next-generation six-speed automatic transmission “Mazda SKY-Drive”* for more enjoyable driving and better fuel efficiency

The next-generation six-speed “Mazda SKY-Drive”* automatic transmission was also developed in line with the “Mazda SKY concept.” “Mazda SKY-Drive”* features improvements across the board, but particularly focuses on reduced power loss and an improved direct feel. In addition to improving fuel economy by approximately 5%,
“Mazda SKY-Drive”* delivers a responsive and refined, direct shift feel comparable to a dual clutch transmission.
