Both the SQ5 and AMG GLB have child safety locks to prevent children from opening the rear doors. The SQ5 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 AMG GLB’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.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the SQ5 are reminded to check the back seat if they opened the rear door before starting out. The AMG GLB doesn’t offer a back seat reminder.
The SQ5 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The AMG GLB doesn’t offer front seat center airbags.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi SQ5 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Mercedes AMG GLB has not been tested.
Over 200 people are killed each year when backed over by motor vehicles. The SQ5 has standard Maneuver Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The AMG GLB doesn’t offer automatic braking for stationary objects directly to the rear.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The SQ5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The AMG GLB doesn’t offer a system that can receive automated systems from infrastructure.
The SQ5’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the AMG GLB.
The Audi SQ5 offers an optional Top View Camera System and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Mercedes AMG GLB doesn’t offer a camera washer, requiring manual cleaning.
Both the SQ5 and the AMG GLB have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Audi SQ5 weighs 562 pounds more than the Mercedes AMG GLB. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Audi SQ5 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The AMG GLB has not yet been evaluated by the IIHS for 2025.
