The 1.5-liter Toyota M15A-FXE hybrid engine was unveiled at the 2019 Auto Show alongside the fourth generation of the well-known Yaris model based on the GA-B or TNGA platform. Like the A25A-FXS and M20A-FXS motors, this unit belongs to the Dynamic Force Engine 2.0 series.
The Dynamic Force family also includes the engines: A25A-FKS, A25A-FXS, M15A‑FKS, M15A-FXE, M20A‑FKS, M20A-FXS, T24A-FTS.
The engine was installed on:
- Toyota Aqua 2 (XP210) since 2021;
- Toyota Yaris 4 (XP210) since 2019;
- Toyota Yaris Cross 1 (XP210) since 2020.

Disadvantages of the M15A-FXE engine
- A compression ratio of 14.0 hints at rather high requirements for fuel quality.
- In specialized forums, they only complain about leaks in the EGR liquid cooler.
- This heat exchanger can even crack and antifreeze will fall directly into the engine cylinders.
- After 100,000 km, the EGR valve often becomes clogged with deposits and completely jams.
Hi, the M15A-FXE, used on the Yaris Cross in Europe, specially the Yaris Cross, comes from Factory with 0W-8 GVL-1 Oil. Recommended from Toyota is the 0W-8 with possibilities of 0w16 and 0w20 as well as 05w-30 oils. However, as exception to the 0W-8, one can use the 0W16 or 0W20, but must revert to 0W-8 on the next Oil change. I run a check world wide and it seems to be the same everywhere. It is a controversial kind of recommendation, but it is on the Service and user manual. Most countries in Northern Europe say 0w16; the southern countries even 0w20. There is no explanations for it as such, and no extra service pages for it. People are afraid of such a thin oil.
Fact is, regularly Toyota services change oil first at one year or 15K km. So if it is dangerous it is straight on the first year with the 0W8. Strange or not?
If one goes around racing these engines regularly, than better buy it and change the oil to 0W-20 immediately after the first 1000 km.
These engines hardly get hot, and hardly run past 90/94 Deg Celcius. It is an Atkinson engine, and on an Hybrid even, almost never reaches 90 C. I run many hours with 80 C Oil temp. Sometimes 74 C. I rest my case
