New-generation technologies that embody the
Sustainable Zoom-Zoom plan
Mazda announced its “Sustainable Zoom-Zoom” long-term vision
for technological development in March 2007. This vision commits
us to make “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 this plan, Mazda has announced that it will raise
the average fuel economy of the Mazda vehicle fleet sold
worldwide 30% by 2015, compared with the 2008 levels.
Building Block Strategy
—The popularization of environmental technologies
itself makes a real contribution
With the arrival of hybrid and electric vehicles in recent years, a
car’s functionality can be described as the comprehensive
strength of its base technologies in the engine, transmission,

body, and chassis, as well as electric devices like regenerative
braking and hybrid systems.
Nevertheless, it is forecasted that gasoline- and diesel-fueled
internal combustion engines will continue to account for the ma-
jority of automobile powertrains even as far ahead as 2020. We
are therefore pursuing a Building Block Strategy of improving the
base technologies for a car’s basic performance, and gradually
adding electric devices such as regenerative braking and hybrid
systems. Our approach is to effectively reduce CO2 emissions by
providing all customers with driving pleasure and outstanding en-
vironmental and safety performance, rather than to rely heavily
on a subset of environmentally friendly vehicles.Improving the
efficiency of the internal combustion engines upon which cars
are based, for example, allows for smaller electric devices like mo-
tors and batteries in hybrid vehicles as well.
This approach will make it possible to achieve Mazda’s driving
pleasure in hybrid vehicles.
