Toyota Develops New Series of Gas Engines That Will Boost Fuel Efficiency At Least 10%

Toyota City, Japan – 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.
