gainful

I was giving a loaner 2020 GLC when I brought in my 2017 GLC for service. Noticed quite a few things:

1. The engine is louder on 2020, more exhaust notes than the 2017 engineer which is mostly metallic noise.
2. The ride on 2020 is much more improved over the 2017 --soak up bumps really well -- I am not sure it is the suspension that is re-turend, or the tire has been improved (both have the Pirelli Scorpion AS run-flat). The 2020 with tire pressure at 40 psi has a more supply ride than my 2017 at 32 psi.
3. The 2020 steering is slightly heavier than the 2017. Overall the ride on 2020 is much better, but it lost some agility that came with the 2016-2019 model.
4. Interior quality is much improved too. Panels fit tighter together and there is no squeaking or any sort. More solid construction.
5. Didn't notice a material difference between the acceleration of the two.

What do you guys feel?

Thanks for the update, looking forward at some point to get a 2020 loaner to see how it is (and be jealous of course...)

Point 2, may just be new Scorpions versus older. I noticed that the ride and sound quality of the scorpions seem to degrade the more miles on them. possible they did re-tune the suspension though
Point 4 may also be related to time, though as the 2020 are the 5th year with many of the same trim components it is possible they have engineered fixes for some annoyances that cropped up over the years

I just returned a brand new 2020 loaner (Coupe) that I had while they were getting my 2016 CPO GLC 300 SUV ready. My 2016 has far fewer options, sad to say. But it has non-runflats, which makes the ride (IMO) better than the 2020 I had (which had the RFs). Both are quicker than the 2012 C300 I traded in. The 2016 is solid and quiet and very sure footed on dry roads. The tires that came with it aren't highly rated for snow and/or ice, and I've felt that on the snow/ice patches I've hit. If the winter becomes too snowy here, I'll have to look at snow tires.

I did not like the sloped hatchback of the coupe, but that's just my preference. I felt the same way when I had an X5 and got an X6 as a loaner. Both the 2020 loaner and my 2016 have the same sound system. The loaner had Nav and all the other goodies, like Apple Play. Mine does not. The original owner of my 2016 paid the upgrade for the big moon roof, but didn't get Nav. To each his own, I guess. The loaner had the hands-free tailgate, which was sweet. Mine does not, but I'll live with that. And the loaner had the best heated steering wheel I've ever encountered. It heated up in a instant. My 2016 has heated seats, but not the steering wheel. Bummer.

If this GLC 300 serves me as well as my C300 did, I may trade it in on a new one in a year or two. Really liking the GLC 300 line so far, though.

I recently had a 2020 loaner while my 2019 GLC300 was in for service.

Here are my notes:

1. New Comand system was hard to get used to, no wheel, just touch pad.
2. The larger format screen was nice, but then again, the graphics are different and took some getting used to.
3. The rear view mirror made the look out the back appear much more confined. Did they change the rear window size in the hatch? I found that I had a hard time seeing out the rear view mirror.
4. There was more noise in the cabin. My 2019 has the Acoustic glass and the 2020 did not.
5. The engine/transmission performance was not as smooth and linear as my 2019.
6. I won't comment on the ride since my 2019 has the AMG Line package and the 2020 loaner did not.

If I were to choose, I'd keep the 2019. It just felt like a better vehicle.

Same with me. Took my 17 in for service I have the Night package/ AMG line 19 inch and they gave me 2020 GLC for the day. I didn’t like it.
The steering wheel controls were confusing everything seemed cluttered together, the engine sounded louder inside the cabin compared to mine which sounds quiet inside. I have acoustic glass don’t know if that’s a difference.
I have Michelin Defenders LTX replaced the Continentals RFL after 20k miles mine has a quieter softer ride don’t miss the RFL at all. If I had to spend 55k again I think I would look around for something different. Maybe.

I am debating whether to lease a GLC 300 2020 after I turn in my leased GLC 300 2017 (18 inch wheels). A major concern of mine is ride quality. I am a bit worried about some of the comments here as well as some recent online reviews of the GLC 300 2020,

For example, at Cars.com (https://www.cars.com/articles/2020-m...aulers-410781/) the authors write:

“The only issue I have with the GLC300’s driving dynamics is the ride quality, which is surprisingly stiff. I credit my test vehicle’s 20-inch wheels and low-profile tires as the culprit here.”

and at motor1.com (https://www.motor1.com/reviews/37499...0-first-drive/), the authors write:

“The GLC’s nimble nature comes at the cost of ride quality, though, and the crossover’s multi-link front and rear suspensions’ stiff tuning leaves heads tossing and cargo turning while going over small road irregularities. That said, it’s likely the GLC’s standard 18-inch wheels and all-season tires make for a less rigid ride.”

Has anyone else found the GLC 300'’s 2020 ride a but stiff compared to that of previous years’ GLC 300s?

I also attribute the 2020 loaner's stiffer ride to the runflats. I once owned a Z4 with runflats and it also had a harsh ride until I swapped them out for standard tires.

I noticed the noise reducing felt material is gone under rear cargo.

My 2018 with acoustic glass and 18" was chosen specifically for the soft and quiet ride. Hope they didn't mess that up with "tech" upgrade. BMW did that with E90 LCI so I wouldn't be surprised.
