I bought a 2015 GL350 for towing. Did the research and it will fit my needs. 7,500lb tow ability and 20mpg when I'm just in town. If you are ordering new, make SURE you have the trailer hitch package! If the vehicle does not have it, it's a lot for the dealer to install. Any gas powered vehicle will not get the same MPG as gasoil/diesel powered vehicles. The other big thing is how much easier even the 3L V6 tows over the gas 4.5L. Mine has 455lb/ft of torque, and that is what is needed for towing. Check some of the utube videos, with towing and MB, Lexus, or whatever vehicle in the search.

 

Thanks for your feedback. Should have mentioned I'm in the US so we don't get the diesel model MB. The 2020 GLS450 with the hybrid assist has 369lb/ft of torque and the GLS580 has 516lb/ft

 

You can't get a bluetec? I'm in Idaho, but had to go to Portland, OR to get the vehicle I wanted. Yes, it is not "new", but I paid 1/3 the price of the new vehicle. I love the fact I can get 27mpg on the highway, and that is measured, not just a guess.

 

A shame, but MB stopped selling diesels outside of Sprinter in NA. Hold on to yours, as you won't be able to get a newer one again! I would have loved to get a newer MB, mines a 2013, but I believe 2016 or 2017 is the final year for diesel.

 

Awesome cars, enjoy your Bluetec, but by all means don't do the oil changes as Mercedes indicates, I lost my engine at 160K miles, but dead set on rebuilding it, I love the car, CHANGE THE OIL AT 3k MILES!!!!!! please don't believe the bull crap about 10K mile oil changes, its going to cost me over 10K to fix, fortunately they make a better crank in the UK than the soft metal crank Mercedes puts in there from factory, mine never clunked or overheated or even hesitated, just seized, started and went for another 5 miles with no signs of damage and seized again, so fortunately since it had new oil and a full crankcase, and did not overheat, the damage did not go beyond the crank, just very sad that Mercedes sets you up for failure. ENJOY YOUR DIESEL, I am driving a newer gl 550 biturbo and am desperate to saddle up in my diesel again.

 

I had have 2012 GLS350 Diesel, did many many many mile while towing 6000lb travel trailer. This car I have replaced with 2022 GLS450. I was really worried if the new car will be able to do the same towing. To my surprise.. so far it is perfect. Last year did multiple trips across the USA, one road trip was 3800 miles in 10 days through Utah, Arizona, California.. Now second season, as today I have tow around 7000 miles total. With a good experience. It has more power than the diesel, the 9 speed gear box behaves much better than the old 7 speed. The mileage deteriorated little bit, from 13-14 mpg to 11-12 mpg, but nothing critical. The air suspension works well as it did in the old one. (I have to confess to a sin.. I don't use weight distribution hitch, because it was messing with the air suspension, I do keep the trailer hitch weight under 500 lb and let the car to be leveled by the air.)

The only issue I see is the position of the 7-Way plug receiver. It's heading down with steep angle, it's real pain to plug the connector reliably and if you use the Bluetooth brake controller, it's heading down and it lets very small clearance for the cable. This issue I will have to address by adding there some custom bracket.
