#1 factor ngaun is fuel injector spray pattern and timing, fuel rail pressure and timing, latest fuel system as a whole(kasama na dito egr, vgt, butterfly valve timing.) Kaya lahat ng All new SUVs tahimik na since they all run the latest CRDI system, much refined and more environment friendly(euro 4.)

An ordinary Joe would see it as super tahimik ng makina kala mo gas engine + euro 4 marked on the owners manual.

I understand 2017 mux is still euro 3 like the prev gen monty, fort and everest.
The 4J series is over a decade old already as far as I know. Sila nauna gumamit ng 3rd generation CRDi sysyem. Let's see how the new 1.9 RZ4E engine fares.
