Hybrid
Test Drive Task: Evaluate the 6-speed transmission shift quality during light acceleration. | Note: While this is a new generation, the Direct Shift-6AT paired with the hybrid system can feel unique; monitor for any unusual hesitation or harsh shifts that feel outside the norm of a modern torque-converter transmission.
Test Drive Task: Cycle through the infotainment system while the vehicle is moving. | Note: Ensure the Lexus Interface system is responsive, as complex tech suites of this generation often benefit from regular software updates to maintain smooth connectivity with smartphone integrations.
Check this by: Examining the front brake wear patterns and listening for noises. | Note: Given the RX500h's performance focus and weight, the braking system works hard; ensure there is adequate pad life remaining, as high-performance friction materials can be a common early-wear item.
Test Drive Task: Check for any wind noise around the side mirrors at motorway speeds. | Note: Some owners have noted occasional cabin noise sensitivity in newer SUVs; verifying this during your test drive helps you understand if the specific unit meets your expectations for Lexus refinement.
