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 Kia Sportage doesn’t offer pretensioners for the middle seat belts.

The GLB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Sportage 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 has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Sportage doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the GLB and the Sportage 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, daytime running lights, rearview cameras, driver alert monitors, available all wheel drive, lane departure warning systems and blind spot warning systems.

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 Sportage 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 Sportage.

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

For better traction, the GLB has larger tires than the Sportage (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 Sportage LX’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 Sportage LX. The GLB’s optional 20-inch wheels are larger than the 19-inch wheels on the Sportage SX Turbo.

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 Sportage 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 Sportage’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 Sportage 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 Sportage (111.4 inches vs. 105.1 inches).

The GLB 250 4MATIC handles at .89 G’s, while the Sportage SX Turbo AWD pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the GLB has a 1.1 inches greater minimum ground clearance than the Sportage (7.9 vs. 6.8 inches), allowing the GLB to travel over rougher terrain without being stopped or damaged.

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

The GLB has 1.4 inches more front headroom and .2 inches more rear headroom than the Sportage.

The front step up height for the GLB is 1.5 inches lower than the Sportage (17” vs. 18.5”). The GLB’s rear step up height is 1.9 inches lower than the Sportage’s (17.5” vs. 19.4”).

The GLB uses gas struts to support the hood for easier service access. The Sportage 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 Kia. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 45% lower rating, Kia is ranked 20th.

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 Sportage 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 Sportage 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 Sportage 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 Sportage 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 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 Sportage’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 Sportage 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 Sportage’s 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 Sportage 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 standard outside mirrors include heating elements to clear off the mirrors for better visibility. Kia charges extra for heated mirrors on the Sportage.

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 Sportage’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 Sportage 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 Sportage.

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 costs extra on the Sportage.

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 Sportage 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 Sportage doesn’t offer an automated parking system.
