For enhanced safety, the front seat shoulder belts of the Maserati Grecale 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 AMG GLA doesn’t offer height-adjustable seat belts.
Both the Grecale and AMG GLA have child safety locks to prevent children from opening the rear doors. The Grecale 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 GLA’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.
The Maserati Grecale 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 AMG GLA doesn’t offer a front passenger side knee airbag.
Over 200 people are killed each year when backed over by motor vehicles. The Grecale has standard Active Park Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The AMG GLA doesn’t offer backup collision prevention brakes.
Both the Grecale and the AMG GLA have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Maserati Grecale weighs 459 to 816 pounds more than the Mercedes AMG GLA. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
