Environmental Vision

Sustainable Zoom-Zoom

Mazda has adopted a long-term vision for technology development called "Sustainable Zoom-Zoom" and is working to help achieve a sustainable future.


l	Basic Policy Provide All Customers who Purchase Mazda Vehicles with Driving Pleasure as well as Outstanding Environmental and Safety Performance.

In March 2007, Mazda adopted the Sustainable Zoom-Zoom long-term vision for technology development to help achieve an exciting, sustainable future for vehicles, people and the Earth. This vision commits Mazda to making vehicles that always excite and that embody a "Zoom-Zoom" feeling, meaning they look inviting to drive, are fun to drive and make you want to drive them again.

Zoom-Zoom Tree

"The Zoom-Zoom tree," shown on the right, embodies the Zoom-Zoom concept and its spread throughout society. The tree absorbs the One Mazda* corporate culture as nutrients through firmly planted roots. As it continues to grow, the left branch represents the environment, the right branch represents safety, and the treetop embodies the Zoom-Zoon concept.


Mazda's Vision on Product Environmental Performance

As vehicle ownership continues to expand around the world, automobile manufacturers must redouble their efforts to achieve cleaner exhaust emissions, and improve fuel economy in order to cut CO2 emissions and help reduce the world's dependence on increasingly scarce fossil fuels. Mazda considers it necessary to develop a multi-solution approach to automobile-related environmental issues that takes into account various factors such as regional characteristics, vehicle characteristics and types of fuel.

Improving the Fuel Economy of Mazda Vehicles 30% by 2015

Mazda has set a goal of raising the average fuel economy of Mazda vehicles sold worldwide by 2015 by 30% compared with 2008 levels.

Based on the Sustainable Zoom-Zoom long-term vision for technology, Mazda cuts CO2 emissions through improved fuel economy and provides all customers who purchase Mazda vehicles with both driving pleasure and outstanding environmental and safety performance.

Promoting the Building-Block Strategy

Mazda adopts the Building-Block Strategy to realize its goal of raising the average fuel economy of Mazda vehicles sold worldwide by 2015 by 30% compared with 2008 levels. Even in 2020, Mazda expects that the world's key energy sources will continue to be mainly petroleum-based and that the majority of vehicles will still be powered by internal combustion engines. Consequently, Mazda's Building-Block Strategy prioritizes improvements in base technologies such as improving the engine's thermal efficiency and reducing the weight of the vehicle body. The next step of the Building-Block Strategy is the gradual introduction of electric devices such as idle-stop, brake energy regeneration, and hybrid powertrains. This approach to reducing total CO2 emissions does not rely on a small proportion of eco-friendly models and enables Mazda to offer customers both driving pleasure and excellent environmental and safety performance. Furthermore, such vehicles can be offered to customers all over the world, including those in developing countries which may lack special infrastructure.

Gradual Application of Electric Devices Technologies (Building-Block Strategy)

Mazda aims to further boost environmental performance by gradually adding electric device technologies to base engines with excellent environmental performance.

Gradual Application of Electric Devices Technologies (Building-Block Strategy)

Based on the Building-Block Strategy, base technologies and electric device technologies are combined in the following three steps.

Step 1:Battery Management Technology (Idling Stop System "i-stop")

The i-stop system automatically shuts the engine off temporarily when the vehicle comes to a standstill. The use of i-stop alone can improve fuel economy by 7% to 10% (as measured in Japanese models). Mazda installed i-stop in the upgraded Axela/Mazda3 in 2009 and has been expanding it to other models. In February 2012, i-stop was installed in the CX-5 equipped with the SKYACTIV-D 2.2 clean diesel engine, marking the first use of an idling stop system in a diesel engine passenger car in Japan.

Step 2: Brake Energy Regeneration Technology (i-ELOOP)

Mazda has developed the world's first brake energy regeneration system for a passenger vehicle that uses a capacitor as an electricity storage device*1. It is the groundbreaking system, which Mazda calls 'i-ELOOP'. As the vehicle decelerates, the system converts kinetic energy into electricity, which can be used later as needed. i-ELOOP is particularly effective in improving fuel economy in real-world driving situations with frequent acceleration and braking. The system was introduced in 2012 with the new Atenza/Mazda6.

Brake Energy Regeneration System "i-ELOOP"

Vehicles require electricity to power variety of electrical components such as headlamps, air-conditioner and audio equipment. Electricity is generated by using engine power to turn a power generator called an alternator. Approximately 10% of engine output is said to be used not for driving, but to generate electricity to power the electrical components.

The goal in developing i-ELOOP was to eliminate the need for the engine to generate electricity.

Step3: Electric Motor Drive Technology (Hybrid System)

This type of system improves overall energy efficiency using an electric motor to assist gasoline engines at times when energy efficiency is low, such as when a vehicle is running at low engine speeds or during low-load operation. The combination of this hybrid system with the systems mentioned in steps 1 and 2 can produce a substantial boost in overall efficiency.

  • Mazda is aiming to begin sales of hybrid vehicles by the end of 2013, starting in Japan. (The hybrid system will be licensed from Toyota Motor Corporation.)

Basic Approach to Safety

Mazda regards the improvement of safety performance as one of the fundamentals of vehicle development and as important as that of environmental performance. Mazda's aim is to achieve a safe, accident-free automotive society from the three perspectives of vehicles, people, and roads and infrastructure. To this end, the Company has formulated the Mazda Safety Policy and is working to deliver a steady stream of technologies and solutions based on it.

Goal A safe, accident-free automotive societyMazda Safety Policy

Based on the awareness that striving for safe vehicles is one of the foundations of a worry-free life, Mazda is committed to the following:

  1. Researching the ways in which customers use Mazda vehicles and the traffic environment in which they are being used
  2. Deepening research into safety technology and reflecting the results of this research in Mazda's products in a way that offers customers the best available and appropriate technology
  3. Contributing to the creation of safe societies through safety communication (products, technologies and safety education)
