8AR-FTS engines have an electronic multi-point fuel injection, but the "E" suffix is not included in the code. Dynamic Force engine series The Dynamic Force engine series introduced in 2017 has a partially different naming scheme. For instance, the two numbers between the first and second letters denotes the displacement of the engine. The rest of the naming scheme (such as the suffix) remains the same as with prior engines. Examples: M20A-FKS M20A is a 2.0-liter engine, as denoted by the "20" in "M20A" F – Normal cylinder head DOHC K – On-demand Atkinson cycle in non-hybrid engines S – D4-S Gasoline direct injection T24A-FTS T24A is a 2.4-liter engine, as denoted by the "24" in "T24A" F – Normal cylinder head DOHC T – Turbocharged S – D4-S Gasoline direct injection Note: Some engines don’t share the same displacement as with the one found in the engine code. The V35A-FTS is a good example of this, where despite the model code designation and marketing materials, the actual displacement of the engine is 3.4-liters, not 3.5. There are some engines that used the naming scheme of the Dynamic Force family of engines but are not actually part of them; a good example of this would be the F33A-FTV engine as despite it not belonging to the Dynamic Force family of engines, it still used the naming scheme normally used for the aforementioned engines. This also applies to the G16E-GTS engine as well.
