Compare the best new & used car deals with Carwow: Meet the updated Mercedes big daddy SUV - the GLS! Mercedes has given its largest SUV a mid-life facelift, and Mat’s got his hands on this behemoth to find out what’s changed and whether it can compete with the likes of the BMW X7 and Range Rover!When it comes to the exterior design… Well, not a whole lot has changed! Around the rear, you’ll find some of the most obvious fake exhausts in the business, while there’s also some updated lights and a new bumper. Along the side, the only changes are new alloy designs, and upfront, the most notable difference is the huge grille - which is definitely an improvement on the old model! Step inside and the similarities to the previous gen continue, but thankfully it’s still a pretty luxurious place to sit. There’s a huge digital dial screen (with lots of customisation available) coupled with a big infotainment screen in the centre of the dash. There’s a fair bit of storage throughout the cabin, and the seats are super comfortable. What’s more, bar a few small areas, pretty much everything is coated in soft-touch materials. There are four engines to choose from with the new GLS. At the start of the range, you can pick a 3-litre straight-six turbo petrol or diesel, and these deliver 380hp and 370hp respectively. At the top-of-the-range is the AMG GLS 63, which is packing a 4-litre twin-turbo V8 that can put down 612hp. All cars come with a 9-speed automatic gearbox and four-wheel drive. So it sounds pretty impressive, but there’s one issue - the starting price is around £108,000! So is it worth it?! You’ll need to stick with Mat and see for yourself!Chapters00:00 Intro00:39 Design02:56 Price04:14 Interior09:06 Back Seats14:21 Boot16:31 5 Annoying Things18:!4 5 Good Things20:02 Engines20:47 Town Driving23:37 Motorway Driving25:20 Country Road Driving26:42 0-60mph27:29 Verdict
