Lexus RX 450h Hybrid System Malaysia — 3.5L 2GR-FXE, eCVT & Inverter Coolant
The RX 450h uses Toyota's 3rd-generation Hybrid System: 2GR-FXE 3.5L Atkinson cycle V6 (295 hp system output) + front and rear motor-generators + P710 NiMH battery + eCVT. The AWD system is achieved electrically — the rear motor generator provides rear-wheel drive without a mechanical rear prop shaft. Key maintenance facts: (1) inverter coolant: flush every 100,000 km or 10 years with Toyota Super Long Life Coolant (pink) — at specialist RM 400–700; (2) eCVT fluid: change every 80,000 km; (3) P710 NiMH battery warranty: 8 years/160,000 km, replacement RM 8,000–15,000; (4) HV battery health diagnostic: Techstream shows individual cell voltages and capacity — essential before purchasing a used RX 450h; (5) regenerative braking means front brake pads last 50,000–70,000 km instead of the usual 30,000–40,000 km. Fuel economy Malaysia: 12–16 km/L in mixed driving.
