But he was shocked with disbelief as my car was not making as much noise as he had expected. Actually it was barely noticeable in lower RPMs. Maybe the upgraded hydraulic engine and gearbox mounts made the difference reducing vibration and sound.
Sound is definitely there and it's not that bad. But I can totally see this car's engine getting trashy at speeds above 120.
The engine sound can be heard at high revvs mostly when accelerating in first and second gears, but at lower rpms the sound is barely audible, and also thanks to the brilliant sound insulation too.
I doubt the engine mounts help in reducing the noise inside. The mounts if improperly fit, might give abnormal vibrations while cranking the engine and while going on irregular roads.

The i20s that I've been in and driven do sound refined. What I've been trying to say is that even though the engine noise can be heard inside other cars, it sounds refined when you compare it to the Polo's engine noise which sounds archaic in comparison.
If there are excessive vibrations at start, predominantly appearing from front, then you should get your engine mounts changed too. Open the bonnet, and ask someone to crank the engine while you watch the engine vibrations from front of bonnet. If you can see the whole cabin shaking, time to report to workshop.
I used to feel abnormal vibrations few months back, but mine was just a case of tightening a few nuts and bolts of the mount.
About the engine noise- There are many damping materials available in market which are effective too. When you plant to upgrade speakers in future, you can get some damping done.
