NEXT GENERATION POWERTRAINS

gMazda SKY concepth|Driving pleasure and excellent environmental performance for all

We intend to deliver Mazda's signature values of driving pleasure and excellent environmental and safety performance to all our customers.
To do this, we began by thoroughly researching the base technologies supporting automobile performance as we developed the innovative
gMazda SKYTECHh powertrain technology.

Fuel economy and torque increased by up to 15% Next-generation direct injection gasoline enginegMazda SKY-Gh*

To achieve a breakthrough with the gasoline engine, Mazda engineers conducted intensive research into innovative ideas and technologies for achieving ideal combustion. These ideas are combined in the next-generation direct injection gasoline engine gMazda SKY-G,h* which is currently under development. The fuel economy of the gMazda SKY-G* 2.0Lh engine demonstrates about a 15% improvement over the current 2.0L gasoline engine. In performance terms, it has been confirmed that the engine generates approximately 15% more torque.

20% better fuel economy, low and high end torque boosted Next-generation clean diesel engine gMazda SKY-Dh*

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 gMazda SKY-Dh* 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 gMazda SKY-Driveh* for more enjoyable driving and better fuel efficiency

The next-generation six-speed gMazda SKY-Driveh* automatic transmission was also developed in line with the gMazda SKY concept.h gMazda SKY-Driveh* 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%,
gMazda SKY-Driveh* delivers a responsive and refined, direct shift feel comparable to a dual clutch transmission.
