 This report focuses on three gasoline engines newly developed by Toyota and a new engine developed by Honda that were exhibited at the JSAE Exposition 2015.

 Toyota exhibited 1.2-liter and 2.0-liter direct-injection turbo engines and a 1.5-liter naturally-aspirated engine. In April 2014, Toyota announced that it would introduce 14 engines of high thermal and fuel efficiencies by the end of 2015. Toyota launched nine of them, including the three mentioned above, by the end of May 2015.

 Honda has developed three direct-injection turbo engines consisting of 2.0-, 1.5- and 1.0-liter models. The 1.5-liter engine was fitted in the all-new Step WGN in April 2015 and was exhibited at the JSAE 2015. It achieves high fuel efficiency and high torque in a practical range that are almost equivalent to those of 2.4-liter engines.

 Toyota and Honda adopted several advanced technologies including the dual VVT and strong tumble flow generation to develop engines of high fuel efficiency and performances.
