For enhanced safety, the front and rear seat shoulder belts of the Mercedes GLC 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 Envision doesn’t offer pretensioners for the rear seat belts.

The GLC’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Envision doesn’t offer pre-crash pretensioners.

The GLC 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 Envision doesn’t offer a whiplash protection system.

The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Active Brake Assist in the GLC as “Superior.” The Envision scores at most only 4 points and is rated only “Advanced.”

The GLC’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 Envision doesn’t offer a driver alert monitor.

Both the GLC and the Envision 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, daytime running lights, rearview cameras, available all-wheel drive, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mercedes GLC is safer than the Buick Envision:

For better traction, the GLC has larger standard tires than the Envision (235/60R18 vs. 225/60R18). The GLC’s tires are larger than the largest tires available on the Envision (255/45R20 vs. 235/50R19).

The GLC’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Envision Premium’s 50 series tires.

For better ride, handling and brake cooling the GLC has standard 20-inch wheels. The Envision’s largest wheels are only 19-inches.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the GLC can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Envision doesn’t offer run-flat tires.

The GLC offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Envision’s suspension doesn’t offer adjustable shock absorbers.

The GLC has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GLC’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Envision doesn’t offer a load leveling suspension.

The GLC has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Envision doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the GLC’s wheelbase is 4.8 inches longer than on the Envision (113.1 inches vs. 108.3 inches).

For better handling and stability, the track (width between the wheels) on the GLC is 1.8 inches wider in the front and 1.7 inches wider in the rear than on the Envision.

The GLC 300 4MATIC handles at .83 G’s, while the Envision Premium pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The GLC 300 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the Envision Premium (26.6 seconds @ .66 average G’s vs. 27.5 seconds @ .63 average G’s).

The engine in the GLC is mounted longitudinally (North-South), instead of sideways, as in the Envision. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Buick. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 13% lower rating, Buick is ranked 8th.

Unlike the driver-only memory system in the Envision Essence/Premium, the GLC offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLC’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Envision’s passenger windows don’t close automatically.

If the windows are left open on the GLC the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Envision can only operate the windows from inside the vehicle, with the ignition on.

The GLC has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Envision doesn’t offer a locking fuel door.

The GLC’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Envision’s standard manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are optional on the GLC to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Envision doesn’t offer heated windshield washer nozzles.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The GLC’s available headlights were rated “Good” by the IIHS, while the Envision’s headlights are rated “Acceptable” to “Poor.”

To help drivers see further while navigating curves, the GLC offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Envision doesn’t offer cornering lights.

The GLC’s optional Active Parking Assist can parallel park or back into a parking spot by itself, starting and stopping automatically, with the driver only responsible for switching from reverse to drive. The Envision Premium’s automatic parking system requires operating the brakes and transmission to safely park.

The GLC will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLC will retain 44.66% to 45.7% of its original price after five years, while the Envision only retains 39.59% to 40.17%.

According to The Car Book by Jack Gillis, the GLC is less expensive to operate than the Envision because it costs $109 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the GLC than the Envision, including $419 less for a timing belt/chain.

Motor Trend selected the GLC as their 2017 Sport Utility of the Year. The Envision has never been chosen.

The Mercedes GLC outsold the Buick Envision by over two to one during the 2019 model year.
