Improving the Fuel Economy of Mazda Vehicles 30% by 2015
Building Block Strategy
Providing all customers with driving pleasure and outstanding environmental and safety performance
Mazda’s Technologies
Ev 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.
With this outlook, Mazda is working on the development of
its Building Block Strategy in order to meet its goal of raising the
average fuel economy of Mazda vehicles sold worldwide by
30% by 2015 compared with 2008 levels.
Rather than rely significantly on a limited number of environ-
mentally friendly vehicles, Mazda has taken an approach of
effectively reducing overall CO2 emissions by providing all
customers with driving pleasure and outstanding environmental
and safety performance. Through rapid advances in base
technologies for basic functions, including in engines, transmis-
sions, bodies, and chassis, we are successively introducing
electric devices like regenerative braking technology and hybrid
systems. We refer to this as our Building Block Strategy.
