The passenger compartment of the Q3 remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of the driver and passenger.  Audi showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  In the full-width rigid barrier test, protection of the chest was adequate for both the driver and rear passenger, and protection of all other critical body areas was good.  In both the side barrier impact and the more severe side pole test, maximum points were scored, with good protection of all critical body areas.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric assessment of the rear seats also indicated good whiplash protection.  The standard-fit autonomous emergency braking system performed well in tests of its functionality at the low speeds, typical of city driving, at which many whiplash injuries are caused.

In the frontal offset and side barrier tests, protection of the 6 and 10 year dummies was good or adequate for all critical body areas.  The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position.  Clear information is provided to the driver regarding the status of the airbag and the system was rewarded.  All of the restraint types for which the Q3 is designed could be properly installed and accommodated in the car.

The protection provided by the bonnet to the head of a struck pedestrian was predominantly good or adequate, with some areas of poor protection only on the stiff windscreen pillars.  The bumper provided good protection to pedestrians' legs at all test locations.   Protection of the pelvis was mixed.  The AEB system is able to detect vulnerable road users such as pedestrians and cyclists.  In most tests of these functionalities, the system performed well, with collisions avoided or their severity mitigated, even at night-time in the case of pedestrians.

The Q3 has a seatbelt reminder system for the front and rear seats.  The AEB system performed well or adequately in various tests of its functionality at highway speeds.  A standard-fit lane-keep assist system helps to keep the car from drifting out of lane and can also intervene in more severe emergency situations.  A driver-set speed limiter helps the driver maintain control of the vehicle speed.
