Name one technological feature of the QX55's interior.

The dual-display infotainment system is a standout technological feature of the QX55's interior. This system enhances the driving experience by allowing for better multitasking and access to various functions simultaneously. The top display primarily handles navigation and entertainment functions, while the lower display is dedicated to climate controls and other vehicle settings, providing an intuitive interface for the driver and passengers. This dual-screen setup not only makes it easier to manage different applications but also contributes to a modern, high-tech aesthetic within the vehicle.

Other choices, while they may hold some merit, do not highlight this key feature. For instance, a single-display infotainment system would not offer the same level of convenience or ease of use. Reclining rear seats are primarily a comfort feature, and while a wireless charging pad is certainly useful, it does not compare in significance to the dual-display system in the context of technological innovation in the QX55's interior.
