How to make WK2 Diesel Quieter

Hi guys! I'm new here. I have 2014 Grand Cherokee Eco-Diesel. I want to know how to make it as quiet as a Bluetec Diesel. I almost bought an ML350 or a GL 350 Mercedes. They are extremely quiet compared to the Grand Cherokee at 40K more dollars. Am thinking of Dyna-matting the rear interior of my GC. I had an 07 Toyota Sienna LTD AWD before this, and at least one owner did this to his Sienna to make it quiet. This problem is probably an age thing. But I like it QUIET. This new GC is noisier than my Sienna was on the highway, but the fuelage of this GC is amazing compared to my Sienna.(double the mileage)
Also, this was the only vehicle that had all the features that I wanted. Heated steering wheel, diesel, air suspension, tow package, etc.... But I wish it was quieter on the highway. Love the power, hate the road and engine noise. Don't want a Mercedes, because the creature features are way better in the GC, And way less dollars !! Looks are better too !!!

The GC is a bit noisy at start up and at low revs around 20 -30 MPH. But at highway speeds it is extremely quiet, I saw one test where at 70 mph they were registering something like 67 db. Apart from and depending on wind direction the mechanicals are eerily silent on tge highway, absolutly no complaints from me.

This is my opinion as well.
I have some vibration at idle but once under way it goes away and is very quiet. Btw, I'm not that young either!

I also looked at the MB, BMW and Audi options but chose the jeep as well!

Depending on the tires that came on it, you might try a "touring" radial of some kind. Check tirerack.com for some reviews. I had some Michelin touring radials on my last car, and they were pretty quiet.

Check out sounddeadenershowdown.com. In order to block out exterior noise, you'll want MLV. Home Depot sells a cheap alternative:

It won't be an easy/fun task.

Are you trying to reduce engine noise (since you referenced a Bluetech engine) or just overall road noise? As someone else noted, tires make a huge difference. When I put Goodyear Silent Armour tires on our old 2008 WK, I no longer had to adjust the radio volume every time I hit the freeway section with rough pavement.

The ecodiesel is a little noisier than the Mercedes engine in our 2008 at a cold startup.

The MB is MUCH quieter than the GC diesel, to the point it is difficult to tell it is a diesel. I drove both the GLK250 and ML350 Bluetec and if the dealer had been better to work with I'd have one of them today. Part of it is they have a heavy rubber gasket that surrounds the engine and seals to the bottom of the hood blocking a lot of the noise. I don't know if sound deadening inside would do much; they should have that already.

Regardless of what others think in terms of how quite it is (I agree I think mine is very quite, although I have a v8) - to answer the OPs question, I think dynamat is really your best option. My biggest concern is that you have to take off panels, and lots of them depending on where you want to dynamat and that could introduce rattles and squeaks. If you do decide to go forward with it any quality car audio shop can handle the work.
