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 Hyundai Tucson doesn’t offer pretensioners for the middle seat belts.

Both the GLB and the Tucson have standard driver and passenger frontal airbags, front side-impact 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, crash mitigating brakes, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

To reliably start during all conditions and help handle large electrical loads, the GLB has a standard 800-amp battery. The Tucson’s 600-amp battery isn’t as powerful.

The GLB’s 2.0 turbo 4-cylinder produces 60 more horsepower (221 vs. 161) and 108 lbs.-ft. more torque (258 vs. 150) than the Tucson SE/Value’s standard 2.0 DOHC 4-cylinder. The GLB’s 2.0 turbo 4-cylinder produces 40 more horsepower (221 vs. 181) and 83 lbs.-ft. more torque (258 vs. 175) than the Tucson SEL/Sport/Limited/Ultimate’s standard 2.4 DOHC 4-cylinder.

In heavy traffic or at stoplights the GLB’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Tucson doesn’t offer an automatic engine start/stop system.

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 Tucson.

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 Tucson doesn’t offer an SMG or a conventional manual transmission.

For better traction, the GLB has larger tires than the Tucson (235/55R18 vs. 225/60R17).

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 Tucson SE/Value’s standard 60 series tires.

For better ride, handling and brake cooling the GLB has standard 18-inch wheels. Smaller 17-inch wheels are standard on the Tucson SE/Value. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the Tucson Sport.

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 Tucson doesn’t offer run-flat tires.

Suspension and Handling

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 Tucson’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 Tucson doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the GLB’s wheelbase is 6.3 inches longer than on the Tucson (111.4 inches vs. 105.1 inches).

For greater off-road capability the GLB has a 1.5 inches greater minimum ground clearance than the Tucson (7.9 vs. 6.4 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

The GLB offers optional seating for 7 passengers; the Tucson can only carry 5.

The GLB has 1.1 inches more front headroom and .1 inches more rear headroom than the Tucson.

The front step up height for the GLB is 2 inches lower than the Tucson (17” vs. 19”). The GLB’s rear step up height is 2.5 inches lower than the Tucson’s (17.5” vs. 20”).

The GLB uses gas struts to support the hood for easier service access. The Tucson uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Hyundai. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 52% lower rating, Hyundai is ranked 22nd.

When three different drivers share the GLB, the memory seats and mirrors make it convenient for all three. Each setting activates different, customized memories for the driver and front passenger’s seat positions and outside mirror angle. The Tucson doesn’t offer a memory system.

The GLB’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The Tucson doesn’t offer an easy entry system.

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 Tucson doesn’t offer a heads-up display.

The GLB’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Tucson’s standard power window switches have to be held the entire time to close them fully. Only its driver’s window opens 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 Tucson 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 Tucson’s standard manually variable intermittent wipers have to be constantly adjusted.

The GLB’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Tucson Value/SEL/Sport/Limited/Ultimate.

When the GLB is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Tucson’s mirror doesn’t automatically adjust for backing.

The GLB’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Tucson offers an automatic rear view mirror, but its side mirrors don’t dim.

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 Tucson.

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 Tucson SEL/Sport/Limited/Ultimate.

Both the GLB and the Tucson 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 Tucson doesn’t offer rear air conditioning vents, only heat vents.

The GLB has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Tucson doesn’t offer a house-current electrical outlet.

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