Toyota develops new series of fuel efficient gas engines

ABR Staff Writer Published 11 April 2014

Toyota will soon introduce vehicles globally with a series of newly-developed, highly efficient gasoline engines that achieve outstanding thermal efficiency 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 1.3L gasoline engine using the Atkinson cycle normally used in dedicated hybrid vehicles that achieves a maximum thermal efficiency of 38% -- top-level among mass-produced engines.

The second is a 1.0-liter gasoline engine, jointly developed with Daihatsu Motor that has achieved maximum thermal efficiency of 37%.

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.
