Toyota City, Japan (April 10, 2014) — Toyota will soon introduce vehicles globally with a series of newly-developed, highly efficient gasoline engines that achieve outstanding thermal efficiency1 and fuel efficiency improvements of at least 10%.
The new engines leverage combustion and loss-reduction technologies Toyota has refined in its dedicated hybrid engines. Two engines will form the base of the new series. The first is a 1.3-liter gasoline engine using the Atkinson cycle normally used in dedicated hybrid vehicles that achieves a maximum thermal efficiency of 38 percent — top-level among mass-produced engines. The second is a 1.0-liter gasoline engine that has achieved maximum thermal efficiency of 37 percent.
The new engines will be used in models scheduled for partial redesign in the near future, and a total of 14 engine variations will be introduced globally by 2015.
