If you’re in the market for a luxury seven-seat SUV then put the new Mercedes-Benz GLS on your shortlist ­– as, besides offering three rows of seats, Mercedes is keen to let you know that this version is the ‘S-Class of SUVs’ – quite a claim.

This isn’t a car that’s just been lightly freshened-up in an effort to attract more buyers, mind; this-generation GLS is bigger in every direction than before and features new underpinnings, engines and exterior styling.

It’s also packed with a range of advanced modern equipment, befitting of a flagship SUV with a three-pointed star adorning its nose – which should help Mercedes tackle rivals such as the long-wheelbase Range Rover and BMW X7.

Restrained, handsome styling

You won’t miss the GLS out on the road, in part due to its sheer size – it’s a whopping 5,207mm long, making it longer than both the X7 and long-wheelbase Range Rover, and it’s almost two metres wide.

Substantial footprint aside, the new second-generation GLS - or third-generation if you include the earlier GL-Class - features a completely overhauled exterior. Its styling is softer than its predecessor, resulting in a more restrained and dignified look, making the Mercedes a more subtle luxury SUV than the likes of the X7. It even looks a little more cohesive than the smaller GLE.

Limited engine range

Only one version of the GLS is initially available in the UK. Called the GLS 400 d, it features a stout 3.0-litre diesel that produces 330hp and a whopping 700Nm of torque, channelled to all four wheels via a nine-speed automatic and Mercedes’ 4Matic all-wheel-drive system.

More versions are joining later on, including a GLS 450 petrol with 367hp, as well as a hot Mercedes-AMG GLS 63 version after that. The UK won’t get the GLS 580 V8 petrol available in other markets.

Interior space for up to seven

The GLS is the firm’s largest seven-seat SUV with space in all three rows for adults. The third row is still best for smaller passengers unless you slide the middle row forwards slightly, but offers a vast amount of boot room if you fold the seats down (all fold electrically). Read on for a more detailed look into the GLS’ practicality.
