The A3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Arteon doesn’t offer pre-crash pretensioners.
Both the A3 and Arteon have child safety locks to prevent children from opening the rear doors.
