Which 2027 Mercedes-Benz GLS changes matter most to Manchester families?

The changes the maker’s figures show for 2027 are price and output. Price rises at every trim with a published figure for both years, the GLS 580 goes from 510 to 530 horsepower and from 538 to 553 lb-ft, and the GLS 450 goes from 369 to 413 lb-ft (Mercedes-Benz, 2027). The 2027 GLS 450 4MATIC® SUV starts at $93,950 (Mercedes-Benz, 2027).

For a Manchester family, that price step matters because it sets the budget before the seating question even starts. The GLS 450, GLS 580 and AMG® GLS 63 each seat seven, with six seats available as an option (Mercedes-Benz USA, 2026).

The Mercedes-Maybach GLS 600 is the exception. It seats five, with four as an option, so a family that needs a third row should start with the other three trims.

How many seats and how much cargo space does the Mercedes-Benz GLS have?

The GLS 450, GLS 580 and AMG® GLS 63 each seat seven, and the Mercedes-Maybach GLS 600 seats five, according to Mercedes-Benz USA’s 2026 specifications. Each of the three seven-seat trims lists 84.7 cubic feet of maximum cargo room.

Third-row space is the number a family feels first. In the 2026 GLS 450, GLS 580 and AMG® GLS 63, the second row offers 41.9 inches of legroom and the third row offers 34.6 inches (Mercedes-Benz USA, 2026). The first row offers 40.3 inches in all three. The Maybach gives its second row more room, at 43.4 inches, but it has no third row to compare.

Cargo room has a second yardstick, and it is worth knowing. Consumer Reports requires a three-row SUV to have 46 cubic feet or more of usable cargo room to qualify for its “most cargo room” rankings. The GLS figure of 84.7 cubic feet is the maximum cargo number the maker publishes, so it measures a different thing. Ask us to show you the cargo area of the GLS 450 or GLS 580 in person at 875 Gold St, Manchester, NH, with the seats in the position you use every day.

What engines, drivetrain and towing does the 2027 Mercedes-Benz GLS offer?

The 2026 GLS 450 makes 375 horsepower and 369 lb-ft of torque, and the 2026 GLS 580 makes 510 horsepower and 538 lb-ft (Mercedes-Benz USA, 2026). The AMG® GLS 63 makes 603 horsepower and 627 lb-ft, and the Maybach makes 550 horsepower and 568 lb-ft. For 2027, the GLS 450 makes 375 horsepower and 413 lb-ft, and the GLS 580 makes 530 horsepower and 553 lb-ft (Mercedes-Benz, 2027).

All four trims list the same 7,700-pound maximum towing rating. The EPA lists each as a hybrid with all-wheel drive, and the combined fuel economy figures are 21 mpg for the GLS 450, 16 for the GLS 580, 17 for the AMG® GLS 63 and 15 for the Maybach GLS 600 (U.S. Environmental Protection Agency, 2026). The EPA’s combined figure weights city driving at 55% and highway driving at 45% (U.S. Environmental Protection Agency, 2026).

Those combined figures are the right ones to compare across trims.

What does a 2027 Mercedes-Benz GLS cost compared with a 2026?

The 2027 Mercedes-Benz GLS starts higher than the 2026 at each trim with a published price for both years. The starting prices, before destination, are below.

Starting prices by trim, before the destination charge:

The destination charge applies on top of these prices.

Model year also changes the New Hampshire registration bill. The town or city permit fee is 18 mills on each dollar of the maker’s list price for a current model year vehicle, and 15 mills for the first preceding model year, with a $5 minimum (New Hampshire General Court, 2026). The rate steps down each year, so the model year a family registers matters, not just the sticker price.

What warranty comes with a new Mercedes-Benz GLS?

The GLS carries a basic warranty of 4 years/50,000 miles (Mercedes-Benz USA, 2026). That coverage applies to the whole nameplate, so the GLS 450, GLS 580, AMG® GLS 63 and Maybach GLS 600 share the same basic term.

For a family, the basic term sets the first years of ownership. A new GLS bought in 2026 or 2027 starts with that same four-year, 50,000-mile coverage, so the model year you choose does not change the basic term. Ask us about the warranty on the exact GLS you are considering at 875 Gold St, Manchester, NH, before you sign.
