For enhanced safety, the front and middle seat shoulder belts of the Mercedes GLB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Buick Encore doesn’t offer pretensioners for the middle seat belts.
The GLB has standard Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Encore offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The GLB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Encore only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
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 Encore doesn’t offer a driver alert monitor.
Both the GLB and the Encore have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front-wheel drive, 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 and blind spot warning systems.
The GLB’s 2.0 turbo 4-cylinder produces 83 more horsepower (221 vs. 138) and 110 lbs.-ft. more torque (258 vs. 148) than the Encore’s 1.4 turbo 4-cylinder.
On the EPA test cycle the GLB 250 4MATIC Auto gets better fuel mileage than the Encore AWD (23 city/31 hwy vs. 24 city/29 hwy).
The GLB has 1.9 gallons more fuel capacity than the Encore (15.9 vs. 14 gallons), for longer range between fill-ups.
An eight-speed automatic (SMG) is standard on the Mercedes GLB, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Encore.
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 Encore 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 Encore:
For better traction, the GLB has larger tires than the Encore (235/55R18 vs. 215/55R18).
The GLB’s optional tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Encore’s 55 series tires.
For better ride, handling and brake cooling the GLB offers optional 20-inch wheels. The Encore’s largest wheels are only 18-inches.
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 Encore doesn’t offer run-flat tires.
For superior ride and handling, the Mercedes GLB has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Buick Encore has a rear torsion beam axle, with a semi-independent rear suspension.
The GLB has standard front and rear stabilizer bars, which help keep the GLB flat and controlled during cornering. The Encore’s suspension doesn’t offer a rear stabilizer bar.
The GLB offers an optional 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 Encore’s suspension doesn’t offer adjustable shock absorbers.
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 Encore doesn’t offer drift compensation steering.
For a smoother ride and more stable handling, the GLB’s wheelbase is 10.8 inches longer than on the Encore (111.4 inches vs. 100.6 inches).
For better handling and stability, the track (width between the wheels) on the GLB is 2.5 inches wider in the front and 2.6 inches wider in the rear than on the Encore.
For greater off-road capability the GLB has a 1.7 inches greater minimum ground clearance than the Encore (7.9 vs. 6.2 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.
The GLB offers optional seating for 7 passengers; the Encore can only carry 5.
The GLB has 1.1 inches more front headroom, .3 inches more front legroom, 1.7 inches more front shoulder room, .5 inches more rear headroom, 2.3 inches more rear legroom and 2.4 inches more rear shoulder room than the Encore.
For enhanced passenger comfort on long trips the GLB’s middle row seats recline. The Encore’s rear seats don’t recline.
The GLB’s cargo area provides more volume than the Encore.

A standard locking glovebox keeps your small valuables safer in the GLB. The Encore doesn’t offer locking storage for small valuables.
To make loading and unloading groceries and cargo easier, especially for short adults, the GLB has a standard power liftgate, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The Encore doesn’t offer a power liftgate.
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 Encore Essence, the GLB has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
The GLB offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Encore doesn’t offer a heads-up display.
The GLB’s power parking brake sets with one touch and releases with one touch or automatically. The Encore has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.
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 Encore’s passenger windows don’t close automatically.
If the windows are left open on the GLB 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 Encore can only operate the windows from inside the vehicle, with the ignition on.
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 Encore’s standard manually variable intermittent wipers have to be constantly adjusted.
While driving with high beams on, sensitive light sensors available for the GLB detect other vehicles which could be blinded and automatically switch to low beams. The Encore doesn’t offer automatic dimming high beams.
To help drivers avoid possible obstacles, the GLB offers optional cornering lights to illuminate around corners when the turn signals are activated. The Encore 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 offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Encore offers an automatic rear view mirror, but its side mirrors don’t dim.
Optional air-conditioned seats in the GLB keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Encore doesn’t offer air-conditioned seats.
The GLB offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Encore.
The GLB 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 is only available on the Encore Essence.
Both the GLB and the Encore offer rear vents. For greater rear passenger comfort, the GLB has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Encore doesn’t offer rear air conditioning vents, only heat vents.
To keep a safe, consistent following distance, the GLB offers an optional Active Distance Assist Distronic, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Encore doesn’t offer an adaptive cruise control.
To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes GLB offers an optional wireless phone charging system (Qi) in the center console. The Encore doesn’t offer wireless personal charging.
The GLB’s optional Active Parking Assist can parallel park by itself, stopping and changing direction automatically. The Encore doesn’t offer an automated parking system.
