The GLB is an attractive luxury SUV for the money. Its boxy shape gives it a distinctive look while providing extra passenger and cargo space. Throw in some of the best technology available on the market and you've got one of the best small luxury SUVs around.
Part of the first GLB generation introduced for 2020
What is it?
The 2020 Mercedes-Benz GLB 250 is an all-new crossover SUV that slots in between the subcompact GLA and larger GLC. Initially, we questioned whether this sort of half-size between segments was really necessary. But after spending considerable time with the GLB, we're glad it exists on a number of levels.
Prices start at $37,595 for the base GLB 250, which is powered by a turbocharged 2.0-liter four-cylinder engine that produces 221 horsepower and 258 lb-ft of torque. An eight-speed dual-clutch automatic transmission sends power to the front wheels. Mercedes' 4Matic all-wheel drive is available as an option.
The GLB sets itself apart from other SUVs in the Mercedes stable with its upright, boxy shape that faintly mimics the larger and pricier G-Class. The proportions and lower ride height make it seem smaller than it is. In reality, it's closer in size to the GLC.
Why does it matter?
The 2020 GLB 250 finds a seemingly perfect middle ground between the too-small subcompact crossover class and SUVs such as the GLC. Taking into account that the GLB costs $5,900 less than the GLC, we consider it a best-in-class contender. With an unusual available third row of seats, the GLB is one of the most versatile vehicles in any class.
What does it compete with?
There aren't a lot of crossovers that can occupy the space between subcompact and small SUVs, and there are even fewer that offer third-row seats. That places the Range Rover Discovery Sport and the Volkswagen Tiguan as its most direct competitors. Most probably won't opt for the third-row seats, so we'd also cross-shop the GLB against the Volvo XC40 and the BMW X1.
How does it drive?
Around town, the GLB gathers speed smoothly and predictably. It hesitates just a bit if you mash the gas from a stop, but that's quickly followed by pleasing acceleration. Mercedes estimates the GLB 250 will accelerate to 60 mph in 6.9 seconds, which means it gets up to speed confidently without feeling as though you're putting undue stress on the drive components.
Handling isn't what we'd consider sporty or fun, but it's capable and instills driver confidence. Based on our initial testing, our main takeaway is that the GLB is impressively easy to drive. For the expected GLB buyer, we contend that's more important.
What's the interior like?
The GLB's boxy shape does wonders for interior volume compared to the more fluidly styled vehicles in the Mercedes lineup. There's a sense of vertical space in the front seats that reminds us of the cavernous G-wagen. The tall windows add to the airy sensation.
The rear seats are curiously less accommodating. The seat cushions are mounted lower to the floor, reducing thigh support for adult-size passengers. Rear headroom is also noticeably lower, though it's still suitable for taller occupants. Unfortunately, we did not get any exposure to the available third-row seats, but it's a fair assumption that they're only suitable for small children.
The GLB 250 garners high praise for driver and front passenger comfort. In our initial testing, we drove the GLB for about eight hours on the highway, and fatigue never set in. Notably, the optional multicontour seats with heating and ventilation are some of the most comfortable we've experienced over long distances. A rudimentary massage function frequently alters the angle of the seatback and cushion to shift your contact points. The moves are subtle but effective.
Further keeping fatigue at bay is the GLB's quiet cabin and compliant ride. Despite its entry-level pricing, the GLB proves itself worthy of the Mercedes-Benz badge.
The cockpit's general layout and design are very similar to the A-Class', upon which the GLB is based. A wide pane of glass houses two separate displays that are placed right in the driver's field of view to reduce distraction. Mercedes' industry-leading MBUX infotainment system remains our favorite for its numerous features and ease of use. Lending some industrial heft to the interior styling are some chunky trim elements with brushed metal-like finishes.
If there's anything to fault the interior for, it would be the sun visors. The tall front windows allow bright sunlight to broil your face slowly throughout the day, and the tiny sun visors do little to prevent that. Those visors don't slide rearward to protect you fully against sunlight from the side either. (Oh, the humanity!) As far as nitpicks go, this is a significant one that we hope is remedied in the future. Otherwise, the interior is excellent.
How practical is it?
Despite GLB's impression of a small footprint, its cargo capacity is huge. At its maximum with the rear seats stowed, there are 62 cubic feet to fill. That drops to a still impressive 56.7 cubic feet if you add the third-row seats, still larger than the GLC. A low liftover height and standard power liftgate make loading big bulky objects easy. There aren't any remote releases for the second-row seatbacks, so you have to open the rear doors and tug on a nylon strap near the seat-belt buckles to fold the seats down flat.
Up front, there are plenty of places to secure your personal items. The door pockets are large enough to hold a few drink containers, the cupholders feature some clever spring-loaded tabs to keep cups in place, and the center armrest bin is conveniently large. An optional wireless charging pad ensures your phone will stay put too.
What else should I know?
It should be readily apparent by now that we're big fans of this GLB 250, and we're confident you'll agree. It's so good that we're struggling to find any faults, as evidenced by our sun visor diatribe. Whether you're seeking luxury or not, you'd do well to check it out.
Edmunds says
The all-new 2020 Mercedes-Benz GLB is easily one of the best SUVs out there. It's spacious, versatile, luxurious and great to drive. With a starting price under $38,000, it should get some non-luxury shoppers to step up to a premium brand.
Cost to DriveCost to drive estimates for the 2020 Mercedes-Benz GLB-Class GLB 250 4dr SUV (2.0L 4cyl Turbo 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 $3.49 per gallon for premium unleaded in Texas.
Have owned many cars and SUV's, last one a BMW X1. This one looks great, plenty of room, great ride and peppy performance from the turbo 4. The 8 speed dual clutch trans is a gem that seamlessly keeps the vehicle in the right gear to use the wide torque band. The technology can be overwhelming, but slowly getting used to.
This is my first Mercedes Benz. By way of comparison I owed, all new, three Jeep Cherokees/Grand Cherokees (1988,1994, 2000), two Ford Escapes (2009,2012) , and a turbo VW beetle (2004), and a Chevrolet Z-06 Corvette (2004). The workmanship on the GLB (2020) is superlative and way above my other cars. I opted for a number of options, including the AMG package and the larger flat screen … dash. I mentioned those for a couple of reasons, hereinafter.
The AMG package doesn't, in the 2000 model, provide any additional horsepower. It does, however, provide for different styling, drilled rotors, larger wheels, and other items. Whilst the larger wheels are, in my view, better looking you will need to get snow tires as the AMG tires are not all season. So, if you are going to be using it in a snow environment plan ahead for that expense.
Another downside to the AMG package is that the GLB factory mudflaps will not fit the AMG model. I had to use generic items and make them fit.
I am 6'4" so the interior dimensions were important. I fit better in the GLB than the GLC. Moreover the visual sight lines from the GLB are also better. That being said, the driver's cockpit is a bit cramped for me on a lengthy drive. Although the seat has infinite adjustment you still have to contend with the steering wheel and the center console. In long drives I found that the edge of the center console strikes my leg about 4 inches below my right knee, and the door handle is at the same point on the left. It's difficult to move to a comfortable place regardless of where the steering wheel is placed (tilt & telescope). Also, I cannot see the complete speedometer or tachometer because the steering wheel, at my height, is blocking my view. I don't understand why Mercedes Benz does not allow the flat screen to be switched, putting the infotainment system directly in front of the driver and the speedometer/tachometer in the middle (like a Mini Cooper). I purposely bought the heads up display which solves some of those problems. It has sufficient adjustment for my height.
On summer blend gas, with summer tires, I can obtain low 30mpg at 75 to 80 mph on expressways, and mid 20s with winter blend fuel, and snows. City driving, regardless of fuel or tires is low to mid 20s. Because it is a turbo, 91 octane is required.
Turbo lag is not terrible. More annoying is when driving in the "comfort " transmission setting, the upshifts are terrible. You need to really accelerate to overcome the, in my view, lag time on upshifts. I found switching to "sport" in the city eliminates that issue altogether.
Cargo space is great if you are carrying loose sand but, as an example, my golf clubs won't fit without one on the backseats down. Likewise, the roof rails look good but there are no crossmembers so unless you build or find something aftermarket anything narrower than the rails will be resting on the roof.
Last, I tried to find the fuse panel inside the passenger compartment to wire my Valentine v1 and a dash camera. Despite where the owner's manual indicated the fuse panel is in the passenger compartment, it is yet to be found.
Overall I am pleased with the car. I've only 5,000 miles so reliably hasn't been tested.
For a smaller SUV, we found the GLB to offer plenty of elbow room, with ample passenger and cargo space. We didn't need the 3rd row, so we don't have to worry about sacrificing cargo capacity. The base model doesn't include some basic features, such as a garage door opener, enhanced interior ambient lighting, or a heated steering wheel, but we don't feel short-changed at all. We still … have heated seats and plenty of options in our particular vehicle to meet our needs. The 4matic is a MUST in Colorado, so that was an upgrade we couldn't do without. The turbo acceleration is very noticeable, and every mode handles exceptionally well. As first-time MB owners, we are very pleased with the GLB!
The GLB is very attractive, inside and out. It has a very smooth and pleasant ride. And has been excellent in the snow. It has many upscale features as well.
I’ve owned my GLB for 5 weeks and it’s already been in the shop twice. The first time I brought it in was because the car wouldn’t let me unlock it to get in. Once I was in, it said that it couldn’t detect my key and wouldn’t … start. If the key battery is dead, you’re supposed to be notified on the dashboard supposedly. That never happened. I now have to take my car back in because the trunk isn’t closing properly. The power litigate closes and latches the trunk, but it then immediately unlatches.
A few other disappointments are that I gave up some safety features in my Mazda. You’d think a car thats $20,000 more would have those standard, but no. The premium sound system isn’t nearly as good as the BOSE in my Mazda either. Also, the shifting can be jerky from time to time.
