This is a list of piston engines developed, independently or with other car companies, by Toyota Motor Corporation.
Confusion is easiest to avoid when using the dash to separate between the engine series and its own characteristics: for instance, 1MZ-FE rather than 1M-ZFE.
Starting in 2015, the designations after the dash have a maximum combination of three letters, even though there are more suffixes applicable, especially when newer engine technologies are introduced.
For example, both the 2GR-FKS and 8AR-FTS engines have electronic multi-point fuel injection, but the "E" suffix is not included in the code.
The Dynamic Force engine series introduced in 2017 uses a different naming scheme, which is similar to that used by Honda and Suzuki.
