Both the Grecale and GLC 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 GLC’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 GLC 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 GLC doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Grecale. But it costs extra on the GLC.
When descending a steep, off-road slope, the Grecale’s standard Hill Descend Control allows you to creep down safely. The GLC doesn’t offer Hill Descend Control.
Both the Grecale and the GLC have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, 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 415 to 688 pounds more than the Mercedes GLC. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
