The Lexus RX should be capable enough for highway driving based on its listed output. Key figures include 2026 500h F Sport Special: 202 kW; 2025 500h F Sport: 202 kW; 2025 350 Luxury: 205 kW; 2026 500h F Sport Special: 140 kW; 2025 500h F Sport: 140 kW; 5 more variants. Power helps with maintaining speed, while torque matters when merging, climbing gradients or overtaking, so these figures are most useful when viewed through real Malaysian driving conditions.
