Operator notes
Hybrid uses Toyota's proven 2.5L Atkinson (A25A-FXS) + eCVT hybrid system (introduced for 2025). DOES get oil changes (7,500 mi/12 mo). Regenerative braking greatly extends pad/rotor life (often 80k-120k+). Timing CHAIN. Separate inverter/HV cooling loop. eCVT transaxle fluid is long-life (inspect ~60k, service ~100k severe). FL-22 engine coolant ~10 yr/120k.
