The Mercedes-Benz GLS is a large seven-seat luxury SUV designed for Australian families and executives who need generous passenger space, strong towing ability and long-distance comfort. It combines a flexible three-row cabin with all-wheel drive, advanced driver assistance and premium technology, making it suitable for school runs, interstate touring and occasional unsealed-road use. Its size, fuel use and purchase price are substantial, but the GLS offers more family practicality than most flagship sedans and more road-focused comfort than the G-Class.

The Mercedes-Benz GLS is the brand’s largest mainstream luxury SUV and is often described as the S-Class of SUVs. In Australia, it is aimed at buyers who need genuine three-row accommodation, a large luggage area and the comfort expected from a flagship Mercedes-Benz. Its upright body provides easier access than a low luxury sedan, while the long wheelbase creates useful space for passengers in all three rows.
The GLS range combines powerful petrol or diesel engines with automatic transmission and fully variable all-wheel drive. Australian variants are designed for effortless highway performance, towing and carrying a full passenger load. Air suspension helps maintain comfort and control, while selectable driving modes can adapt the vehicle for different road conditions. Despite this capability, the GLS is primarily a luxury road vehicle rather than a hard-core off-roader.
Passenger comfort is a major strength. The first two rows provide generous space, supportive seating and extensive climate-control options. The third row is more usable than in many smaller seven-seat SUVs and can accommodate older children or adults for shorter journeys, although access and luggage space become tighter when every seat is occupied. Electric seat folding makes it easier to switch between passenger and cargo configurations.
Technology includes large digital displays, MBUX infotainment, smartphone connectivity, navigation and a broad range of assistance systems. Depending on the Australian variant and options, equipment can include premium audio, multi-zone climate control, surround-view cameras, advanced cruise assistance and rear-seat comfort features. The number of menus and settings can feel complex at first, so buyers should spend time learning the system during delivery.
The GLS is well suited to Australian interstate travel. Its quiet cabin, stable highway behaviour and strong engines make long journeys relaxed, while the high seating position provides good visibility. Towing capability can support caravans, boats or trailers when the vehicle is correctly specified, but buyers must confirm the exact rating, towbar package and payload for their chosen variant. Fuel consumption rises significantly when towing or driving in urban traffic.
Ownership requires realistic budgeting. The GLS is expensive to purchase, insure, service and equip with replacement tyres. Its length and width can make inner-city parking difficult, and some older garages may not provide enough clearance. For buyers who regularly use seven seats and value luxury, the GLS offers a strong combination of space and refinement. Those who rarely need the third row may find the smaller GLE easier to manage and less costly to run.
Australian families should inspect the GLS with all intended passengers and luggage before purchase. Child-seat placement, third-row access, roof-box use and towing-ball load can affect how much payload remains available. Large wheels can also influence ride comfort and replacement cost, particularly on rough regional roads. Buyers should confirm whether the chosen garage, apartment parking space or holiday accommodation can handle the vehicle’s height, width and turning circle. The GLS is highly capable, but its full value is realised only when the space and touring ability are used regularly.
This also improves everyday ownership confidence.
