The Q4 e-tron Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The C-HR doesn’t offer pre-crash pretensioners.
Both the Q4 e-tron Sportback and C-HR have child safety locks to prevent children from opening the rear doors. The Q4 e-tron Sportback 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 C-HR’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.
To help make backing out of a parking space safer, the Q4 e-tron Sportback 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 C-HR XSE offers Parking Support Brake.
