Safety Comparison

For enhanced safety, the Buick Enclave’s 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 GLS doesn’t offer comfort guides on its middle seat belts.

Both the Enclave and GLS have child safety locks to prevent children from opening the rear doors. The Enclave 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 GLS’ 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.

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 Enclave are reminded to check the back seat if they opened the rear door before starting out. The GLS doesn’t offer a back seat reminder.

The Enclave 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 GLS doesn’t offer front seat center airbags.

To help make backing safer, the Enclave Essence/Premium/Avenir’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLS doesn’t offer a cross-path warning system.

Both the Enclave and the GLS have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty Comparison

Buick’s powertrain warranty covers the Enclave 2 years and 20,000 miles longer than Mercedes covers the GLS. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the GLS ends after only 4 years or 50,000 miles.

The Enclave’s corrosion warranty is 1 year longer than the GLS’ (6 vs. 5 years).

Buick pays for scheduled maintenance on the Enclave for 2 years and 24,000 miles. Buick will pay for oil changes, lubrication and any other required maintenance (up to 2 oil changes). Mercedes doesn’t pay scheduled maintenance for the GLS.

There are over 5 times as many Buick dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

Reliability Comparison

J.D. Power and Associates’ 2017 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Buick 13th in initial quality, above the industry average. With 7 more problems per 100 vehicles, Mercedes is ranked 17th, below the industry average.

J.D. Power and Associates’ 2016 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Mercedes vehicles. J.D. Power ranks Buick third in reliability, above the industry average. With 29 more problems per 100 vehicles, Mercedes is ranked 12th.

From surveys of all its subscribers, Consumer Reports’ April 2017 Auto Issue reports that Buick vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Buick third in reliability. Mercedes is ranked 17th.

Fuel Economy and Range Comparison

On the EPA test cycle the Enclave AWD gets better highway fuel mileage than the GLS 450 V6 (17 city/25 hwy vs. 17 city/22 hwy).

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The GLS requires premium, which can cost 20 to 55 cents more per gallon.

Tires and Wheels Comparison

The Buick Enclave’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Mercedes GLS only has 5 wheel lugs per wheel.

The Enclave has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The GLS doesn’t offer vehicle monitored tire inflation.

Suspension and Handling Comparison

For better handling and stability, the track (width between the wheels) on the Enclave is 2 inches wider in the front and .9 inches wider in the rear than the average track on the GLS.

For better maneuverability, the Enclave’s turning circle is 1.7 feet tighter than the GLS’ (39 feet vs. 40.7 feet).

Chassis Comparison

The Buick Enclave may be more efficient, handle and accelerate better because it weighs about 950 to 1150 pounds less than the Mercedes GLS.

The front grille of the Enclave uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The GLS doesn’t offer active grille shutters.

The Enclave uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The GLS doesn’t offer active noise cancellation.

Passenger Space Comparison

The Enclave has .9 inches more front legroom, 3.9 inches more front shoulder room, .4 inches more rear legroom, 3.4 inches more rear shoulder room and 6.8 inches more third row shoulder room than the GLS.

To make loading groceries and cargo easier when your hands are full, the Enclave’s cargo door can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The GLS doesn’t offer a hands-free gesture to open its cargo door, forcing you to put cargo down if your hands are full.

Ergonomics Comparison

To improve rear visibility by keeping the rear window clear, the Enclave has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the GLS only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Enclave has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the GLS.

Recommendations Comparison

The Buick Enclave outsold the Mercedes GLS by 89% during the 2016 model year.
