Review

The Mercedes GLS has an impressively punchy and smooth diesel engine, and it certainly looks flash inside, but the build quality, ride comfort and handling all disappoint for a luxury SUV of this price.

get the best price

As you’d expect given the GLS’s high starting price, even the entry-level trim is well equipped: keyless entry and start, heated and electrically adjustable leather seats, 22in alloy wheels and air suspension are all included, as are a head-up display and a high-end Burmester stereo.

Right now, this 3.0-litre six-cylinder diesel that produces 325bhp is the only engine on offer in the GLS. It’s impressively smooth and strong, and mostly works well with the standard nine-speed automatic gearbox. However, its average fuel economy is surpassed by most rivals, including the BMW X7 xDrive40d, which is also quicker.
