For enhanced safety, the front shoulder belts of the GMC Acadia are height-adjustable, and the middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Mercedes GLC Coupe has only front height-adjustable 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 Acadia are reminded to check the back seat if they opened the rear door before starting out. The GLC Coupe doesn’t offer a back seat reminder.
The Acadia 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 GLC Coupe doesn’t offer front seat center airbags.
When descending a steep, off-road slope, the Acadia AT4’s standard Hill Descent Control allows you to creep down safely. The GLC Coupe doesn’t offer Hill Descent Control.
The Acadia’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 GLC Coupe.
Both the Acadia and the GLC Coupe 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, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Acadia the rating of “Top Safety Pick” for 2017, a rating granted to only 205 vehicles tested by the IIHS. The GLC Coupe has not been tested, yet.
