The GLC Coupe has standard NECK-PRO front head restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the NECK-PRO front head restraints system moves the headrests forward to prevent neck and spine injuries. The Encore GX doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The GLC Coupe has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Encore GX doesn’t offer backup collision prevention brakes.

The Encore GX doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The GLC Coupe has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Encore GX’s blind spot costs extra.
Both the GLC Coupe and Encore GX have rear cross-traffic warning, but the GLC Coupe has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Encore GX’s Rear Cross Traffic Alert doesn’t automatically brake.
