Compare the2023 Subaru ForesterVS 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 Forester 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 Forester has standard Whiplash-Reducing Front Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Front Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The GLB doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The Forester (except Base/Premium) offers optional Reverse Automatic Braking 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.

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

The Forester’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 Forester (except Base)’s optional 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 Forester 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, rearview cameras, available blind spot warning systems, rear parking sensors and driver alert 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 standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Forester its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The GLB has not been tested, yet.

Subaru’s powertrain warranty covers the Forester 1 year and 10,000 miles longer than Mercedes covers the GLB. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the GLB ends after only 4 years or 50,000 miles.

There are over 65 percent more Subaru dealers than there are Mercedes dealers, which makes it much easier should you ever need service under the Forester’s warranty.

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 Forester’s reliability 46 points higher than the GLB.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Subaru vehicles are more reliable than Mercedes vehicles. Consumer Reports ranks Subaru 12 places higher in reliability than Mercedes.

The flat cylinder configuration of the boxer engine in the Forester lowers its center of gravity, enhancing handling stability without compromising ground clearance. The GLB doesn’t offer a boxer engine configuration.

On the EPA test cycle the Forester gets better mileage than the GLB:

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

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

The Forester has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The GLB doesn’t offer a CVT.

The Forester stops shorter than the GLB:

The Forester Wilderness has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare 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 maneuverability, the Forester’s turning circle is 3 feet tighter than the GLB’s (35.4 feet vs. 38.4 feet).

For greater off-road capability the Forester has a greater minimum ground clearance than the GLB (8.7 vs. 7.9 inches), allowing the Forester to travel over rougher terrain without being stopped or damaged. The Forester Wilderness’ minimum ground clearance is 1.3 inches higher than on the GLB (9.2 vs. 7.9 inches).

The front grille of the Forester 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 Forester has .5 inches more front headroom, 2.2 inches more front legroom, 2.2 inches more front shoulder room, .3 inches more rear headroom, 1.3 inches more rear legroom and 2.3 inches more rear shoulder room than the GLB.

The front step up height for the Forester is 1.5 inches lower than the GLB (15.5” vs. 17”). The Forester’s rear step up height is .3 inches lower than the GLB’s (17.25” vs. 17.5”).

The Forester has a much larger cargo volume with its rear seat up than the GLB with its rear seat up (28.9 vs. 5.1 cubic feet). The Forester has a much larger cargo volume with its rear seat folded than the GLB with its rear seat folded (74.2 vs. 62 cubic feet).

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

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

The Forester has a 1500 lbs. towing capacity. The GLB has no towing capacity.

Standard Trailer Stability Assist on the Forester uses the Vehicle Dynamics 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.

The engine in the Forester is mounted longitudinally (North-South), instead of sideways, as in the GLB. This makes it easier to service and maintain, because the accessory belts are in front.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Forester Premium/Sport/Wilderness/Limited/Touring’s exterior PIN entry system. The GLB doesn’t offer an exterior PIN entry system, and its Mercedes-Benz Emergency Call can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

To improve rear visibility by keeping the rear window clear, the Forester 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.

Consumer Reports rated the Forester’s headlight performance “Good,” a higher rating than the GLB’s headlights, which were rated “Fair.”

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

Both the Forester and the GLB offer available heated front seats. The Forester Touring also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated second row seats aren’t available in the GLB.

Insurance will cost less for the Forester owner. The Complete Car Cost Guide estimates that insurance for the Forester will cost $640 to $1840 less than the GLB over a five-year period.

The Forester will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Forester will retain 54.16% to 57.43% of its original price after five years, while the GLB only retains 46.13% to 48.36%.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Subaru Forester will be $12016 to $17689 less than for the Mercedes GLB.

Consumer Reports® chose the Subaru Forester as its “Top Pick,” the highest scoring vehicle in its category, based on reliability, safety and performance. The Mercedes GLB isn't recommended.

The Subaru Forester outsold the Mercedes GLB by almost five to one during the 2022 model year.
