For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC Coupe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Buick Encore GX doesn’t offer pretensioners for its rear seat belts.
The GLC Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Encore GX doesn’t offer pre-crash pretensioners.
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.
The GLC Coupe offers an optional Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Encore GX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GLC Coupe. But it costs extra on the Encore GX.
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.
To help make backing out of a parking space safer, the GLC Coupe has standard Rear Cross-Traffic Alert and Active Brake Assist automatically engages the brakes to help avoid a collision. Buick charges extra for Rear Cross Traffic Alert on the Encore GX and the Encore GX’s Rear Cross Traffic Alert does not include automatic braking.
The GLC Coupe’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Encore GX doesn’t offer a driver alert monitor.
Both the GLC Coupe and the Encore GX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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 and available lane departure warning systems.
The Mercedes GLC Coupe weighs 695 to 943 pounds more than the Buick Encore GX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
