Compare the2025 Kia Sorento HybridVS 2024 Mercedes GLB

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.

Over 200 people are killed each year when backed over by motor vehicles. The Sorento Hybrid SX Prestige has standard Parking Collision Avoidance-Rear that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The GLB doesn’t offer automatic braking for stationary objects directly to the rear.

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.

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, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

The GLB has not yet been evaluated by the IIHS for 2024.

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:

To lower fuel costs and make buying fuel easier, the Kia Sorento Hybrid uses regular unleaded gasoline. The GLB requires premium, which can cost on average about 84.9 cents more per gallon.

The Sorento Hybrid has 4.2 gallons more fuel capacity than the GLB (17.7 vs. 13.5 gallons), for longer range between fill-ups.

The Sorento Hybrid stops shorter than the GLB:

For better ride, handling and brake cooling the Sorento Hybrid has standard 19-inch wheels. Smaller 18-inch wheels are standard on 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 1.6 inches wider in the front and 2 inches wider in the rear than on the GLB.

The Sorento Hybrid has .3 inches more front legroom, 3.2 inches more front shoulder room, 2.6 inches more rear legroom, 3.2 inches more rear shoulder room, 2 inches more third row headroom, .5 inches more third row legroom and 9.2 inches more third row shoulder room than the GLB.

The Sorento Hybrid’s cargo area provides more volume than the GLB.

The Sorento Hybrid’s cargo area is larger than the GLB’s in almost every dimension:

The Sorento Hybrid has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The GLB doesn’t offer seats that fold into the floor.

Pressing a button automatically lowers the Sorento Hybrid’s second row seats, to make changing between passengers and cargo easier. The GLB doesn’t offer automatic folding seats.

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.

Both the Sorento Hybrid and the GLB have standard heated front seats. The Sorento Hybrid SX Prestige also has standard heated second row seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.

Standard air-conditioned seats in the Sorento Hybrid SX Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The GLB doesn’t offer air-conditioned seats.
