Compare the2023 Kia SportageVS 2022 Mercedes GLB

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

Over 200 people are killed each year when backed over by motor vehicles. The Sportage Prestige has standard Parking Collision Avoidance-Reverse that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The GLB doesn’t offer backup collision prevention brakes.

The Sportage’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GLB.

To help make backing out of a parking space safer, the Sportage EX/SX/Prestige/X-Line/X-Pro’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The GLB doesn’t offer a cross-path warning system.

Both the Sportage and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, blind spot warning systems and around view monitors.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Sportage the rating of “Top Safety Pick” for 2022, a rating granted to only 155 vehicles tested by the IIHS. The GLB has not been tested, yet.

The Sportage comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The GLB’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Kia’s powertrain warranty covers the Sportage 6 years and 50,000 miles longer than Mercedes covers the GLB. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the GLB ends after only 4 years or 50,000 miles.

There are over 2 times as many Kia dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Sportage’s warranty.

On the EPA test cycle the Sportage FWD gets better fuel mileage than the GLB 250 FWD (25 city/32 hwy vs. 24 city/32 hwy).

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

The Sportage offers an optional space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the GLB; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed. Some tire options on the GLB don’t have a run-flat feature, either.

The Sportage has standard front and rear gas-charged shocks for better control over choppy roads. The GLB’s suspension doesn’t offer gas-charged shocks.

For greater off-road capability the Sportage has a greater minimum ground clearance than the GLB (8.3 vs. 7.9 inches), allowing the Sportage to travel over rougher terrain without being stopped or damaged.

The Kia Sportage may be more efficient, handle and accelerate better because it weighs about 50 to 250 pounds less than the Mercedes GLB.

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

The Sportage has .3 inches more front legroom, 1.8 inches more front shoulder room, .1 inches more rear headroom, 3.2 inches more rear legroom and .7 inches more rear shoulder room than the GLB.

The Sportage has a much larger cargo volume with its rear seat up than the GLB with its rear seat up (39.6 vs. 5.1 cubic feet). The Sportage has a much larger cargo volume with its rear seat folded than the GLB with its rear seat folded (74.1 vs. 62 cubic feet).

The Sportage has a 2500 lbs. towing capacity. The GLB has no towing capacity.

Standard Trailer Stability Assist on the Sportage uses the Electronic Stability Control sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. The GLB doesn’t offer electronic trailer sway control.

Heated windshield washer nozzles are optional on the Sportage (except LX/EX/X-Line) to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The GLB doesn’t offer heated windshield washer nozzles.

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

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Sportage has standard extendable sun visors. The GLB doesn’t offer extendable visors.

The Kia Sportage outsold the Mercedes GLB by almost four to one during the 2021 model year.
