The Q6 e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RZ doesn’t offer pre-crash pretensioners.
Both the Q6 e-tron and RZ have child safety locks to prevent children from opening the rear doors. The Q6 e-tron has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The RZ’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Q6 e-tron has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The RZ doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
To help make backing out of a parking space safer, the Q6 e-tron has standard Rear Cross-Traffic Assist with Automatic Brake Activation, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the RZ Premium/Luxury offers Parking Support Brake.
