friendliness that customers demand;
Future
•Continue to advance internal combustion technology and pursue
hydrogen combustion technology; and

Mazda is improving dynamic performance to realize its vision for its powertrains. The Company
is also improving its powertrain’s environmental friendliness, so customers can savor its perfor-
mance to the fullest. In the near future, Mazda will significantly overhaul the performance and
fuel economy of its models powered by gasoline and diesel internal combustion engines. The
Company will add vehicles powered by biofuels and hybrid technologies over the near term,
and is making sustained research efforts into hydrogen-fuel-powered engines as well. The latter
effort is to prepare for the eventual emergence of a hydrogen fuel-based society. At Mazda, we
consider powertrain enhancements to be a critical concern for performance and fiscal
reasons, and accordingly we are earmarking resources for this area.

Reciprocating Gasoline Engines
In October 2005, Mazda announced it would unveil the proprietary Smart
Idling Stop System (SISS). SISS will be introduced in the Mazda Advancement
Plan period. The technology noticeably improves fuel economy. Plans also
call for the adoption of an E85-compatible* flexible fuel engine during the
term of the Mazda Advancement Plan. We expect that by the early part of
the 2010s, practically all of Mazda’s engine lineup will be replaced with
all-new engines built on optimal-combustion technologies.
