Both the Sorento Hybrid and GLB have child safety locks to prevent children from opening the rear doors. The Sorento Hybrid has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The GLB’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 Sorento Hybrid are reminded to check the back seat when a sensor determines the back seat is occupied. The GLB doesn’t offer a back seat reminder.

The GLB doesn’t offer backup collision prevention brakes.

The Sorento Hybrid’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 Sorento Hybrid’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 Sorento Hybrid and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, blind spot warning systems, rearview cameras, driver alert monitors, available all wheel drive 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 “Good” rating, the Insurance Institute for Highway Safety grants the Sorento Hybrid the rating of “Top Safety Pick” for 2022, a rating granted to only 159 vehicles tested by the IIHS. The GLB has not been tested, yet.

The Sorento Hybrid 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 Sorento Hybrid 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 Sorento Hybrid’s warranty.

On the EPA test cycle the Sorento Hybrid gets better mileage than the GLB:

Regenerative brakes improve the Sorento Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The GLB doesn’t offer a regenerative braking system.

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

The Sorento Hybrid has 1.8 gallons more fuel capacity than the GLB (17.7 vs. 15.9 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Kia Sorento Hybrid higher (7 out of 10) than the Mercedes GLB (5). This means the Sorento Hybrid produces up to 8 pounds less smog-producing pollutants than the GLB every 15,000 miles.

The Sorento Hybrid’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the GLB are solid, not vented.

The Sorento Hybrid stops shorter than the GLB:

The Sorento Hybrid has a standard 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.

For better handling and stability, the track (width between the wheels) on the Sorento Hybrid is 1.8 inches wider in the front and 2.2 inches wider in the rear than on the GLB.

The Sorento Hybrid has a 2000 lbs. towing capacity. The GLB has no towing capacity.

Standard Trailer Stability Assist on the Sorento Hybrid 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.

To improve rear visibility by keeping the rear window clear, the Sorento Hybrid 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 Sorento Hybrid has standard extendable sun visors. The GLB doesn’t offer extendable visors.

Manual rear side window sunshades are available in the Sorento Hybrid to help block heat and glare for the rear passengers. The GLB doesn’t offer rear side window sunshades.
