Compare the2025 Volvo XC40VS 2024 Mercedes GLB

Both the XC40 and GLB have child safety locks to prevent children from opening the rear doors. The XC40 Ultra 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 XC40 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.

The XC40 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The GLB doesn’t offer a whiplash protection system.

The XC40 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The GLB doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The XC40 has a standard CTA Auto Brake 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the XC40. But it costs extra on the GLB.

The XC40’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 XC40 and the GLB have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and available around view monitors.

The XC40’s corrosion warranty is 7 years longer than the GLB’s (12 vs. 5 years).

Volvo pays for scheduled maintenance on the XC40 for 3 years and 30,000 miles.

Mercedes doesn’t pay scheduled maintenance for the GLB.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the XC40’s reliability 23 points higher than the GLB.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Volvo vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Volvo 4 places higher in reliability than Mercedes.

The XC40’s 2.0 turbo 4-cylinder hybrid produces 26 more horsepower (247 vs. 221) than the GLB’s 2.0 turbo 4-cylinder hybrid.

The XC40 has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The GLB doesn’t offer a cap-less fueling system.

For better stopping power the XC40’s front brake rotors are larger than those on the GLB:

The XC40 stops much shorter than the GLB:

For better traction, the XC40’s optional tires are larger than the largest tires available on the GLB (245/45R20 vs. 235/55R18).

The XC40 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.

The XC40 B5 Plus handles at .86 G’s, while the GLB 250 4MATIC pulls only .83 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the XC40’s turning circle is 1 foot tighter than the GLB’s (37.4 feet vs. 38.4 feet).

For greater off-road capability the XC40 has a greater minimum ground clearance than the GLB (8.1 vs. 7.9 inches), allowing the XC40 to travel over rougher terrain without being stopped or damaged.

The XC40 is 7.6 inches shorter than the GLB, making the XC40 easier to handle, maneuver and park in tight spaces.

The XC40 has .8 inches more front shoulder room and 1.4 inches more rear shoulder room than the GLB.

The XC40 has a much larger cargo volume than the GLB with its rear seat up (20.4 vs. 5.1 cubic feet).

A control in the cargo area automatically lowers the XC40’s optional rear seats, to make changing between passengers and cargo easier. The GLB doesn’t offer automatic folding seats.

The XC40 has a 3500 lbs. towing capacity. The GLB has no towing capacity.

Optional Trailer Stability Assist (TSA) on the XC40 uses the Dynamic Stability and Traction 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 XC40 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.

Both the XC40 and the GLB have standard heated front seats. The XC40 also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.

The Volvo XC40 outsold the Mercedes GLB by 68% during 2023.
