Compare the2023 Mercedes GLBVS 2023 Buick Enclave

For enhanced safety, the front and second-row seat shoulder belts of the Mercedes GLB 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 Enclave doesn’t offer pretensioners for its second-row seat belts.

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

For enhanced safety, the front seat shoulder belts of the Mercedes GLB are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Buick Enclave doesn’t offer height-adjustable front seat belts.

The Mercedes GLB has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Enclave doesn’t offer knee airbags.

The GLB’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 Enclave doesn’t offer a driver alert monitor.

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

The GLB comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Enclave’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The GLB’s corrosion warranty is unlimited miles longer than the Enclave’s (unlimited vs. 100,000 miles).

To reliably start during all conditions and help handle large electrical loads, the GLB has a standard 800-amp battery. The Enclave’s 730-amp battery isn’t as powerful.

As tested in Car and Driver the Mercedes GLB is faster than the Buick Enclave:

On the EPA test cycle the GLB gets better mileage than the Enclave:

The GLB offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Enclave doesn’t offer an SMG or a conventional manual transmission.

For better stopping power the GLB’s brake rotors are larger than those on the Enclave:

The GLB stops much shorter than the Enclave:

The GLB’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Enclave’s standard 65 series tires. The GLB’s optional tires have a lower 45 series profile than the Enclave’s optional 55 series tires.

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

The GLB’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Enclave doesn’t offer drift compensation steering.

The GLB 250 4MATIC handles at .89 G’s, while the Enclave Essence pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The GLB 250 4MATIC executes Motor Trend’s “Figure Eight” maneuver quicker than the Enclave Avenir (27.5 seconds @ .63 average G’s vs. 28.4 seconds @ .6 average G’s).

For better maneuverability, the GLB’s turning circle is .6 feet tighter than the Enclave’s (38.4 feet vs. 39 feet).

For greater off-road capability the GLB has a greater minimum ground clearance than the Enclave (7.9 vs. 7.5 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

The Mercedes GLB may be more efficient, handle and accelerate better because it weighs about 700 to 800 pounds less than the Buick Enclave.

The GLB is 1 foot, 10.4 inches shorter than the Enclave, making the GLB easier to handle, maneuver and park in tight spaces.

The GLB is 6.5 inches narrower than the Enclave, making the GLB easier to handle and maneuver in traffic.

The front step up height for the GLB is 1 inches lower than the Enclave (17” vs. 18”). The GLB’s rear step up height is 1.2 inches lower than the Enclave’s (17.5” vs. 18.7”).

A low lift-over cargo hatch design makes loading and unloading the GLB easier. The GLB’s cargo hatch lift-over height is 28.5 inches, while the Enclave’s liftover is 30.5 inches.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the GLB. The Enclave doesn’t offer locking storage for small valuables.

Unlike the driver-only memory system in the Enclave Premium/Avenir, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, suspension setting, power steering assist, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The GLB’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 Enclave’s passenger windows don’t close automatically.

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

The GLB’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 Enclave’s standard manually variable intermittent wipers have to be constantly adjusted.

To help drivers avoid possible obstacles, the GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The Enclave doesn’t offer cornering lights. The GLB also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The GLB’s optional Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Enclave doesn’t offer an automated parking system.

The GLB will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the GLB will retain 46.13% to 48.36% of its original price after five years, while the Enclave only retains 43.19% to 43.97%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mercedes GLB will be $2535 to $11902 less than for the Buick Enclave.
