Compact SUV with Third Row and Modern Interior

2021 Mercedes-Benz GLB-Class GLB 250 4MATIC 4dr SUV AWD (2.0L 4cyl Turbo 8AM)

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.

A Great SUV, why wear a suit when can wear a Tux

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.

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,

GLB with AMG Option - review

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.

More room than expected

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!
