Mercedes-Benz Tweaks GLA and GLB

mercedes benz tweaks gla and glb

Those of you just itching to get behind the wheel of a new entry-level Mercedes will enjoy the news that Stuttgart has given its smallest vehicles a nip and tuck while also gifting them an electrified powertrain.

In case you fell asleep in Merc 101, let us remind you the GLA and GLB share much in terms of structure and power teams but are styled to target two completely different customers. The GLA attracts those seeking rounded bodywork; the GLB was styled with a t-square and appeals to shoppers who think the G-Wagen is a looker.

For 2024, both get freshened front and rear designs, primarily courtesy of new lighting signatures emitted by snazzy LEDs. Grilles are typically loud Mercedes units, showing up for duty with enormous tri-star badges and an array of styles depending on which option package is chosen. Front bumper areas have been redesigned and there are new choices on the paint palette.

Americans can choose their GLA 250 and GLB 250 with or without 4Matic all-wheel drive guts. Under the hood is a mild hybrid arrangement comprised of a 2.0-liter four-cylinder that features an additional 48-volt onboard power supply for the belt-driven starter-generator. Power checks in at 221 horses and 258 lb-ft of torque backed by an eight-speed dual-clutch. These numbers will seem familiar but this year’s addition of the 48-volt system should fill in any power gaps at low speeds, potentially making these two feel a bit more fleet around town when trying to squeeze into that gap in traffic.

Not to be outdone, the AMG speed freaks made like Burger King and had it their way, tweaking the powertrain to belt out 302 horsepower and 295 lb-ft of torque. They also fettled the dual-clutch transmission and applied their own brand of aggro in the form of AMG-specific grilles and styling addenda, not to mention optional seats offered in snazzy colors.

Speaking of the interior, dual 10.25-inch screens now stand at the ready under a single pane of glass, ready to proffer details on vehicle vitals and infotainment. Packed into the system is the latest iteration of MBUX software, able to wirelessly work with smartphones or serve up a variety of info displays. Burmester sound systems remain optional, and Dolby Atmos is available in some models as well.

The 2024 Mercedes-Benz GLA/GLB and its variants will arrive in U.S. dealerships later in 2023.

    Question for anyone who has leased or bought one of these:

    Are these engaging to drive in any way, or are they relaxing to drive? Because for similar money, you can get a GLC300, and I can tell you with high confidence that is very comfortable and damn close to what I think of a Mercedes to be but in SUVese.

    During our lease GLC300 period, we got a loaner GLA to drive - the prior gen one. Hot garbage. Truly, it was 2010 Chrysler quality. Who in their right mind bought one of those?

      Weird, I posted a long reply yesterday regarding my experiences with these cars and TTAC didn’t allow it it seems…

      Bottom line: my last loaner when my A250 was getting serviced was a brand new facelifted 2023 GLA200 AMG Line without the Advanced Suspension Pack. It drove very nicely and didn’t feel like an SUV at all. Handling was crisp, steering feedback was good and the standard suspension was a splendid compromise between sport and comfort. It’s no sports car but you can toss it around sportily around corners and it will cope nicely. Didn’t detect much understeer either. The 163-hp 1.33-l turbo-4 is a very peppy and agile engine, a bit buzzy when accelerating but smooth and fairly quiet at idle. I don’t like the design of the GLA but the driving qualities were pretty good in my opinion, more than enough to satisfy someone who wants a comfortable and somewhat sporty ride.

    Circa late 2010 I tried to convince my mother to purchase a B class Mercedes. As she was looking for what would be her 'final' car. The B fit all of her requirements regarding visibility, safety, utility and ease of access/egress. However she balked at using 'premium' fuel and rumours of Mercedes maintenance fees and disregarded my suggestion.

  • Nrd515 Usually for me it's been Arby's for pretty much forever, except when the one near my house dosed me with food poisoning twice in about a year. Both times were horrible, but the second time was just so terrible it's up near the top of my medical horror stories, and I have a few of those. Obviously, I never went to that one again. I'm still pissed at Arby's for dropping Potato Cakes, and Culver's is truly better anyway. It will be Arby's fish for my "cheat day", when I eat what I want. No tartar sauce and no lettuce on mine, please. And if I get a fish and a French Dip & Swiss? Keep the Swiss, and the dip, too salty. Just the meat and the bread for me, thanks. The odds are about 25% that they will screw one or both of them up and I will have to drive through again to get replacement sandwiches. Culver's seems to get my order right many times in a row, but if I hurry and don't check my order, that's when it's screwed up and garbage to me. My best friend lives on Starbucks coffee. I don't understand coffee's appeal at all. Both my sister and I hate anything it's in. It's like green peppers, they ruin everything they touch. About the only things I hate more than coffee are most condiments, ranked from most hated to..who cares..[list=1][*]Tartar sauce. Just thinking about it makes me smell it in my head. A nod to Ranch here too. Disgusting. [/*][*]Mayo. JEEEEZUS! WTF?[/*][*]Ketchup. Sweet puke tasting sludge. On my fries? Salt. [/*][*]Mustard. Yikes. Brown, yellow, whatever, it's just awful.[/*][*]Pickles. Just ruin it from the pickle juice. No. [/*][*]Horsey, Secret, whatever sauce. Gross. [/*][*]American Cheese. American Sleeze. Any cheese, I don't want it.[/*][*]Shredded lettuce. I don't hate it, but it's warm and what's the point?[/*][*]Raw onion. Totally OK, but not something I really want. Grilled onions is a whole nother thing, I WANT those on a burger.[/*][*]Any of that "juice" that Subway and other sandwich places want to put on. NO, HELL NO! Actually, move this up to #5.

  • SPPPP It seems like a really nice car that's just still trying to find its customer.
  • MRF 95 T-Bird I owned an 87 Thunderbird aka the second generation aero bird. It was a fine driving comfortable and very reliable car. Quite underrated compared to the GM G-body mid sized coupes since unlike them they had rack and pinion steering and struts on all four wheels plus fuel injection which GM was a bit late to the game on their mid and full sized cars. When I sold it I considered a Mark VII LSC which like many had its trouble prone air suspension deleted and replaced with coils and struts. Instead I went for a MN-12 Thunderbird.
  • SCE to AUX Somebody got the bill of material mixed up and never caught it.Maybe the stud was for a different version (like the 4xe) which might use a different fuel tank.
  • Inside Looking Out Scandinavian design costs only $600? I mean the furniture.
