Mazda Premieres Eco-Friendly and Powerful Next Generation 'SKY-G' and 'SKY-D' Engines at Tokyo Motor Show 2009

HIROSHIMA, JAPAN – October 21, 2009: Mazda Motor Corporation today revealed its next-generation engine line-up and automatic transmission at the 41st Tokyo Motor Show. On display is the ‘Mazda SKY-G’ direct injection gasoline engine, the ‘Mazda SKY-D’ clean diesel engine and the ‘Mazda SKY Drive’ high-efficiency automatic transmission. This year’s Tokyo Motor Show also marks the Japan debut of the Kiyora concept car as an exhibit of Mazda’s next-generation environmental and safety technologies.

Mazda’s theme for the 2009 Tokyo Motor Show is “The Mazda SKY concept— Providing driving pleasure and environmental and safety features for all customers!” Under the headings of “Today,” “Tomorrow” and “The Future,” Mazda is displaying advanced technologies designed to improve the average fuel economy of Mazda vehicles sold globally by 30 percent by 2015. This is one of the goals of Mazda’s long-term vision for technology development, Sustainable Zoom-Zoom.

Promoting concrete initiatives for a sustainable future
In March 2007, Mazda drafted the “Sustainable Zoom-Zoom” plan, detailing the company’s long-term vision for technology development. This vision commits Mazda to making “cars that always excite, look inviting to drive, are fun to drive, and make you want to drive them again,” and to help achieve “an exciting, sustainable future for cars, people and the Earth.” Based on the plan, Mazda has announced that by 2015 it intends to make a 30% improvement on the 2008 average fuel economy of Mazda vehicles sold worldwide.

Intensive improvement of base technologies, progressive introduction of electric devices
Our basic policy is to “Provide all customers who purchase Mazda cars with the joy of driving, as well as excellent environmental and safety performance.” To realise an advanced Zoom-Zoom world, it is crucial to thoroughly improve base technologies for powertrains — the engines and transmissions at the heart of automobile performance — as well as reduce weight and enhance aerodynamics. It is predicted that base engines (internal combustion engines) will still have a high percentage of the global market in 2020.

In addition, Mazda is progressively combining its proprietary i-stop idling stop system, regenerative braking system, hybrid technology and other electrical devices, with the aim of offering more customers higher levels of fun-to-drive and excellent environmental performance.

Step-1 Idling stop system
Mazda’s idling stop system, i-stop, automatically shuts down the engine when the vehicle stops momentarily. The system yields an improvement of 8% to 10% in fuel economy (with Japan models). Mazda is installing i-stop as our first SKYTECH electrical device in the new Axela and Biante models from 2009.

Step-2 Regenerative braking system
This energy recovery technology converts kinetic energy into electricity as the vehicle decelerates and stores it for use later as needed. The effectiveness of the system varies depending on how the regenerated electricity is used, but the improvement in fuel economy is expected to range from a few percent to 5% or more.

Step-3 Hybrid systems
In general, the gasoline engine uses an electric motor to assist at times when energy efficiency is poor, such as during low-rpm or low-load operation. A hybrid system is combined with an idling stop mechanism, regenerative braking technology and other features to substantially boost overall efficiency.

Mazda SKY concept — Driving pleasure and an everlasting blue sky
Our aim is to offer driving pleasure and excellent environmental and safety performance to all our customers. We chose the name SKY to represent the following three ideas which formed the basis for the development of our next-generation powertrains: the “sky’s the limit” aspirations of our engineers as they pursue optimal efficiency through unconventional thinking; ensuring an everlasting blue sky; and offering all our customers pure driving pleasure to enjoy under that sky. This thinking played the key role in the development of our new base technologies.

Mazda SKYTECH — Powertrain technology supporting environmental performance for Mazda vehicles
We created the name Mazda SKYTECH for our innovative technology to embody the development concept of the next generation powertrains. This year’s Tokyo Motor Show marks the world premiere of three items based on Mazda SKYTECH.

  • Next-generation gasoline engine: Mazda “SKY-G”
  • Next-generation diesel engine: Mazda “SKY-D”
  • Next-generation automatic transmission: Mazda “SKY-Drive”
