For enhanced safety, the front and middle seat shoulder belts of the Infiniti QX60 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Mercedes GLB doesn’t offer height-adjustable middle seat belts.
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 QX60 are reminded to check the back seat if they opened the rear door before starting out. The GLB doesn’t offer a back seat reminder.
The Infiniti QX60 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GLB doesn’t offer a front passenger side knee airbag.
The QX60 Autograph 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 GLB doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The QX60 has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.
The QX60’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the GLB.
Both the QX60 and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive, around view monitors and driver alert monitors.
The Infiniti QX60 weighs 502 to 1017 pounds more than the Mercedes GLB. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the QX60 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 50 vehicles tested by the IIHS. The GLB has not been tested, yet.
