2020 Lexus UX 250h 2.0L OEM M20A-FXS Hybrid Gasoline Engine

This gasoline engine application belongs to the Lexus UX 250h hybrid system. The M20A-FXS is an Atkinson-cycle 2.0L four-cylinder that works with an electrically assisted powertrain; it is not the conventional UX 200 engine configuration.

Hybrid replacements need particular attention to compatibility with the original transaxle, engine controls and high-voltage system. The gasoline engine alone should never be advertised as a complete hybrid drive unit.
