Overview
by the Edmunds Experts
9/17/2024
The 2025 GLB is Mercedes' second-smallest and second-most affordable SUV. It sits between the entry-level GLA and the popular GLC in size and price, though it's closer in size to the GLC and provides the same amount of cargo space. It boasts tech features found in Mercedes' more expensive models but provides fewer luxury features. And unlike many of its rivals, the GLB sports a distinctive boxy design. There aren't any significant updates for 2025 because Mercedes refreshed the GLB last year with updated styling and more standard tech.
Cost to DriveCost to drive estimates for the 2025 Mercedes-Benz GLB-Class GLB 250 4dr SUV (2.0L 4cyl Turbo gas/electric mild hybrid 8AM) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.76 per gallon for premium unleaded in Utah.
Although it's not considered a compact SUV like the Audi Q5 and BMW X3, the GLB is about the size of one inside and out but costs a little less. Compared to other subcompact SUVs like the BMW X1 and Audi Q3, it's a little larger and provides more passenger room and plenty of cargo space. Surprisingly, the GLB also offers a third row for seven-passenger seating, an uncommon feature for small SUVs. However, it's only large enough for children and eats up most of the cargo area when being used. There are four versions of the SUV: the regular GLB 250, the all-wheel-drive GLB 250 4Matic, the AMG GLB 35 performance model, and the electric EQB, which is reviewed separately.
Competitors to consider
You have a lot of options if you're looking for a small luxury SUV. We like the GLB a lot, but it's worth considering the BMW X1 and Volvo XC40 as well. If you want a larger SUV, two of our favorite compact luxury rivals include the value-packed Genesis GV70 and the GLB's big sibling, the GLC. The BMW X3, which BMW has redesigned for 2025, should also definitely be considered if it's in your budget. See what our test team thinks about the GLB in the Expert Rating below.

Great
8.1
out of 10
We drove the 2025 Mercedes-Benz GLB-Class on our test track and on real roads. Our Edmunds team conducts rigorous independent vehicle testing, driving 500,000 miles a year.The Edmunds Vehicle Testing Team evaluates a fresh batch of vehicles every week, pairing objective assessments at our test track with real-world driving on city streets, freeways and winding roads. The data we gather results in our Expert Ratings. They’re based on 30-plus scores that cover every aspect of the automotive experience.
Performance
8/10
How does the GLB-Class drive? In our testing, the GLB 250 reached 60 mph in 6.5 seconds, which is properly quick and at the top of the class. When you stomp the pedal, there's a noticeable delay before it starts accelerating, but with a lighter pedal application, it gets underway smoothly.
The GLB isn't particularly exciting to drive, but it is more capable than most SUV owners will need. The GLB's brakes are easy to control for smooth stops and impressively strong when you need to make an emergency stop. Around turns, the GLB feels sure-footed and planted.
Comfort
8.5/10
How comfortable is the GLB-Class? The GLB has a smooth ride and front seats that remain comfortable for hours at a time. We also like how the cabin stays pleasantly quiet on the highway, even on rough road surfaces. The climate control system also works well on both hot and cold days to keep you cozy at your desired temperature.
Interior
8.5/10
How’s the interior? The GLB's ride height and tall door openings make it easy to get in and out of. There's no need to step up or stoop down — just slip on in. Once inside, you'll find that all of the controls are logically placed and, after a very short time, you can operate them without having to take your eyes off the road.
The GLB's boxy shape affords generous space compared to most of its competitors. Its tall windows provide excellent outward visibility. One minor downside: The sun visors are too small and don't provide full coverage when moved to the side of the vehicle.

How’s the tech? The GLB gets high marks for its tech features. It comes with Mercedes' MBUX infotainment system and Apple CarPlay and Android Auto smartphone integration. MBUX is the easiest and best system out there, with many ways to control functions. It sometimes take a moment to process voice commands, but they work accurately.
The GLB's driver assist features are particularly good. The adaptive cruise works great whether you're driving in dense highway traffic or cruising on the open highway. The lane keeping assistance can be a little too aggressive in trying to keep you in the lane, but that situation is pretty rare.
Storage
8/10
How’s the storage? The GLB's boxy shape comes in handy when taking on cargo. It'll accommodate big and bulky objects, and the low liftover height of the cargo floor and the standard power liftgate make loading easier. There are also plenty of places to keep your personal items, with large door pockets and a sizable center bin. Spring-loaded cupholder tabs keep narrow beverages secure too.
For family duty, the GLB should work out OK. A rear-facing infant safety seat can fit, but only if you keep the rear seats slid all the way back and the front seats in a reasonable position. We did notice that some car seat bases we tested were a bit hard to latch onto the GLB's car seat anchor points.

Fuel Economy
8/10
How’s the fuel economy? The EPA estimates fuel economy to be up to 28 mpg in combined city/highway driving. That's a little above average for the class. Based on our real-world driving, we suspect the EPA figure should be achievable with a light foot.
Value
7.5/10
Is the GLB-Class a good value? The GLB splits the difference between the smaller and more affordable GLA and the slightly bigger and more expensive GLC. It's an appealing option as long as you know what you're getting. Buying one with a ton of options significantly inflates the price, and at that point you should consider the more refined GLC.
Compared with other extra-small luxury SUVs, you pay a little more for the GLB, but you also get more in terms of space, performance and comfort. As with most models in this class, the quality of materials feels a bit cheap in some areas, but overall the GLB feels worth its price.
Wildcard
8/10
The GLB's upright and boxy styling gives it a more traditional and utilitarian SUV look, which we like. Is the GLB fun? No, not really. But that's mostly because we've only tested the GLB 250 so far. The AMG variant should have drivers seeking more excitement covered.
Which GLB-Class does Edmunds recommend?
The GLB is available in regular and performance trim levels. We recommend the regular GLB 250 or GLB 250 4Matic (if you need all-wheel drive) for most shoppers. It comes well equipped with a long list of standard features and offers several option packages. The AMG GLB 35 performance model is for those who have the budget for a sportier and more powerful GLB.
Purchased the 2021 GLB because I was looking for a compact-sized SUV with third row seating for kids. The GLB also has a modern interior, I like the turbine-style air vents and the "surfboard" infotainment and instrument cluster. Despite what others have said about navigating the infotainment, I don't find it hard or cumbersome to use. However, one nuisance is having to scroll to the … radio presets every now and then on the instrument display, sometimes it doesn't save the last setting. I also like the large panoramic sunroof although that's a $1500 option. The engine is peppy and the car is nimble (for an SUV) and has great class gas mileage. There are a few annoyances though: 1) The 2nd row seats don't fold all the way down IF the seats are moved to the front most position (the headrest hits the front seats), this makes it even more difficult to climb into the 3rd row; 2) Android Auto and Apply Carplay doesn't take up the full 10.25 inch infotainment screen, Google Maps only displays 7 inches. Hopefully Mercedes will update it to fill the screen.
The GLB isn't very stylish, isn't very fast and performance-oriented, and it's not the most luxurious Mercedes; however it offers the perfect practicality. The only competitor is the Discovery Sport which is also a compact, luxury SUV with a third row.
18 months on - A great ride with a cautionary tale
A follow up to my earlier review "A nice blend of space, tech and value". Had this car for 18 months now - finished the first service.
All the key points are very valid. The car offers exceptional space for a small SUV, easy to handle, great tech, super boot space.
One nagging issue from the start was poor gas mileage. Right from the time we took possession of the car in 2021, we … never got close to the advertised gas mileage. I asked about that in the first service check and got no response from the dealer except everything was ok. A few months past first service, the engine light came on and stayed on. We didnt take the car in immediately and suddenly found ourselves with an unreliable engine that died on. On taking it in for service, the CSR immediately mentioned that some GLB engines had faulty engines with leaking cylinders. They took the car in and replaced the engine cylinders as it was within warranty. Since then the mileage is exactly as advertised and the car performance is great.
Moral of the story - if you GLB isnt giving you good mileage - get your engine cylinders checked,
I have a defective vehicle built during COVID…Rain water accumulates next to the driver’s side seat. After 6 attempts for the dealership to identify the issue they determined that replacing the door and frame seals would work. Two weeks later the vehicle was ready…Went to pick it up and they did a horrible job on installing the new seals and they cut the headliner too where it didn’t … even meet the seal. Needless to say I left the vehicle to redo the repair, in the interim I filed a claim with MB Customer Care… Two and a half weeks later the vehicle was ready… I Inspected the vehicle with the service manager and found a 10 inch circular wet spot on the headliner in the rear of the vehicle. At this point the service manager said that he was going to work with MB Corporate and assigned me to a sales consultant to get me out of the vehicle and into another at my current lease price….Here it is a almost 2 months later my vehicle still has the original leak and the headliner above the driver gets wet and is stained and the electronic display flashes on and off and the AC fan sounds like a jet engine. I cannot get help from Mercedes-Benz corporate or any response from the dealership.
This one is a lemon!
As with any family, with an additional kid we had to upgrade from my coupe. We were searching for a SUV that had space for kids and a dog, provided the latest tech and was efficient enough for California gas prices. After doing a month of research, the GLB fit the badge very well. We liked the look and the interior tech.
We have had it for a month now. The mileage is as advertised. Not … the most performance oriented engine but it can be zippy enough. We got parking assist which is really for city driving and parking. Music system is decent. All this at a price for a loaded regular brand. It’s been a good ride so far.
We have a limited number of reviews for the 2025 Mercedes-Benz GLB-Class, so we've included reviews for other years of the GLB-Class since its last redesign.
