The GLS 450 suits most Manchester, NH drivers; the GLS 580 suits V8 buyers
The GLS 450 4MATIC® fits most Manchester drivers. It starts at $90,250 and makes 375 horsepower. The GLS 580 4MATIC® starts at $116,150 and makes 510 horsepower, and it is the trim for drivers who want the V8 and the optional suspension.
The maker lists optional E-ACTIVE BODY CONTROL on the GLS 580 4MATIC® only. In its words, “Optional E‑ACTIVE BODY CONTROL for the GLS 580 4MATIC® is one of the most intelligent SUV suspension systems on the market” (Mercedes-Benz USA Media Newsroom, 2026). At Mercedes-Benz of Manchester, we sell both trims, so you can start with the one that matches how you drive.
What gas mileage do the GLS 450 and GLS 580 get around Manchester?
The GLS 450 4MATIC® is rated 19 mpg city, 24 highway and 21 combined. The GLS 580 4MATIC® is rated 14 city, 20 highway and 16 combined (EPA, 2026). For a daily drive, the combined rating is the number that matters most.
According to the U.S. Census Bureau’s 2020 to 2024 American Community Survey, Manchester workers have a mean travel time to work of 23.9 minutes (U.S. Census Bureau, 2024). A driver who spends that long in the car each day will see the GLS 450’s 21 combined mpg at the pump every week.
Is the GLS 450 powerful enough, or do you need the GLS 580’s V8?
The GLS 450 4MATIC® makes 375 horsepower and 369 lb-ft of torque from a six-cylinder engine. The GLS 580 4MATIC® makes 510 horsepower and 538 lb-ft of torque from its V8. The maker’s newsroom lists the two engines as an inline-six and a V8 (Mercedes-Benz USA Media Newsroom, 2026).
If you want the V8’s 510 horsepower and 538 lb-ft, the GLS 580 is the trim for you. If 375 horsepower and 369 lb-ft cover your driving, the GLS 450 does the job at a lower price.
How do the GLS 450 and GLS 580 handle New Hampshire snow and rough roads?
“All GLS models are equipped standard with 4MATIC® fully variable all-wheel drive (Torque on Demand)” (Mercedes-Benz USA Media Newsroom, 2026). That means both trims send power to all four wheels, with no add-on needed.
Both trims also ride on standard AIRMATIC® air suspension. The maker says it delivers a modern, well-balanced ride with firmer, sportier tuning than before, while keeping a high level of ride comfort (Mercedes-Benz USA Media Newsroom, 2026). For Manchester roads, the GLS 450 gives you the same all-wheel drive and standard suspension at the lower price.
What do the GLS 450 and GLS 580 cost to buy?
The GLS 450 4MATIC® starts at $90,250 and the GLS 580 4MATIC® starts at $116,150, both 2026 manufacturer prices. AMG® Line is standard on the GLS 580 and optional on the GLS 450. The GLS 450 rolls on 21-inch alloys as standard, and the GLS 580 rolls on AMG® 22-inch wheels (Mercedes-Benz USA).

Who should skip the GLS 580, and who should skip the GLS 450?
The GLS 580 is not the right pick for a driver who wants the lower price and better combined fuel economy. It starts at $116,150 and is rated 16 mpg combined.
The GLS 450 is not the right pick for a driver who wants V8 power, the 22-inch AMG® wheels or E-ACTIVE BODY CONTROL. For that driver, the GLS 580 is the trim. Seating and all-wheel drive do not decide between them, because both trims have the same seven seats and 4MATIC® system.
