Mercedes-Benz GLA or GLB: which fits Manchester, NH drivers?
The GLB fits most Manchester drivers better, because its extra cargo room and optional third row suit a household that carries gear through a New England winter. The GLA is the better pick for a solo or two-person driver who wants the smaller footprint. Both are sold new at Mercedes-Benz of Manchester, so the choice can be made on the lot.
Winter, parking, price and seating each change the answer, so each gets its own section below.

Which fits Manchester drivers better, the Mercedes-Benz GLA or GLB?
The GLB fits most Manchester drivers better, because it gives more cargo room and an optional third row for a household that carries gear. The GLA suits a solo or two-person driver who wants the smaller footprint. The maker’s figures show the gap: the GLA 250 carries 50.5 cubic feet of maximum cargo, and the GLB 250 carries 62.0 cubic feet. The GLB can also seat seven, a third-row option the GLA’s published figures do not show. We stock both new at 875 Gold Street, so the comparison can be made in one visit.
How many passengers can the GLA and GLB seat?
The GLA suits a driver who carries a passenger or two. The GLB is the one with an optional third row, which brings it to seven seats for a larger household. The GLB seats five as standard, with seven optional on each GLB trim the maker lists. Its front and second rows measure 41.1 and 38.1 inches, against 41.0 and 38.0 inches in the GLA, so a driver with one or two passengers gets nearly the same room in either. A family of four or more that rides together most days should start with the GLB.
Which has more room for winter gear and strollers, the GLA or GLB?
The GLB has more room for winter gear and strollers, with 62.0 cubic feet of maximum cargo against 50.5 cubic feet in the GLA 250. That room matters for skis, snow tires and sports gear through a New Hampshire winter. A household that loads the back with a stroller and cold-weather gear on the same trip gets the most from the extra space. A driver who packs light will find the GLA’s 50.5 cubic feet enough.
Is the smaller GLA easier to park and drive around Manchester?
Yes, the GLA is the easier of the two to park, and that is its case for a commuter who parks in tight spaces. The GLA 250 4MATIC® measures 173.6 inches long and 63.5 inches tall. The AMG® GLB 35 measures 183.1 inches long and 65.4 inches tall, with a wheelbase of 111.4 inches. If most of your parking is tight, the shorter GLA is the simpler car to park. A household that needs the GLB’s room gives up some of that ease, and it is a fair trade when the room gets used.
Which handles a New Hampshire winter better, the GLA or GLB?
Both models offer Mercedes-Benz 4MATIC® all-wheel drive, so traction in a snowstorm is a point both can meet. What separates them through a New Hampshire winter is the GLB’s room for gear and passengers, set against the GLA’s smaller size. Manchester has a long winter. The nearest station that reports snowfall, Massabesic Lake on the city’s eastern edge 4.5 miles from the airport, recorded 52.8 inches of snow a year and 71.4 days a year with an inch or more on the ground (NOAA National Centers for Environmental Information, 1991 to 2020 U.S. Climate Normals). The 4MATIC® versions are the GLA 250 4MATIC® and the GLB 250 4MATIC®.
How do GLA and GLB prices and running costs compare?
The GLA starts lower, and the GLB costs more for the room it adds. The GLA 250 SUV starts at $41,500, against $43,800 for the GLB 250 SUV. The GLA 250 also posts the better fuel figures at each pairing, with 29 mpg combined against 28 for the GLB 250.

|---|---|---|---|
| GLA 250 SUV | $41,500 | 26 / 34 | 29 |
| GLA 250 4MATIC® SUV | $43,500 | 25 / 33 | 28 |
| AMG® GLA 35 SUV | $58,550 | 22 / 30 | 25 |

The EPA combined figure weights city driving at 55% and highway driving at 45% (40 CFR part 600, subpart D), so it reflects a mix of stop-and-go and open-road driving. We offer upfront pricing, so the starting price is a figure you can see before you visit. Both models carry the maker’s basic warranty of 4 years or 50,000 miles.

Frequently asked questions
Does the Mercedes-Benz GLB really have a third row?
Yes, as an option. The GLB seats five as standard, and seven seats are available on each GLB trim the maker lists. Choose the seven-seat setup only if someone rides in the back most weeks.
Is the GLA or GLB better for a family of four in New Hampshire?
Four people fit in either, since both list front and second-row legroom for the seats. Seating alone does not settle it. The GLB is the better choice when the family’s gear goes along on every trip.
Do the GLA and GLB come with all-wheel drive?
Yes, with the 4MATIC® version. The GLA 250 4MATIC®, the GLB 250 4MATIC® and both AMG® 35 models are all-wheel drive.
What does the Mercedes-Benz GLA cost compared with the GLB?
The GLA’s starting price is lower at every matching pair of trims. The GLB’s higher price pays for its larger cargo area and optional third row. Compare the starting price first, then the trade-in and financing steps, which decide the final number.
