Hybrid
Test drive task: Perform a low-speed parking maneuver while shifting between Drive and Reverse. | Description: Listen for any hesitation or clunking in the nine-speed transmission, as the integration between the electric motor and the V8 can sometimes feel complex under heavy load.
Check this by: Cycling through the MBUX infotainment and digital dash menus while idling. | Description: Since this vehicle relies heavily on software for its hybrid management and luxury features, ensuring the screen responsiveness is sharp is a good way to gauge the health of the onboard computers.
While driving: Find a smooth stretch of road and switch between Comfort and Sport+ modes. | Description: Observe the Airmatic suspension's ability to adjust; if it feels overly harsh or slow to react in one corner, it could indicate the early stages of a sensor or air-strut adjustment quirk.
Check this by: Inspecting the brake rotors and pads thoroughly after a short drive. | Description: Given the substantial weight of the hybrid system, the brake wear can be accelerated; ensure there is no visible lipping or excessive heat discoloration on the rotors.
