Td5 is much better than older models. Bar maybe a good V8. But most Td5’s have more sound proofing. Puma models are a bit better. But tbh this is more down to the design of a Defender. They have poor NVH as the body is made up of lots of bits. And it is all bolted together, metal to metal onto the chassis.Hi,
I own a TD5 110 and on long journeys (I'm driving the high way to get to the destination) the noise level drives me (sometimes) crazy .
How is the noise level comparable between the different engines TDI, TD5, TD4 2.4 and TD4 2.2?

Mine is ex-military with a 300tdi and no soundproofing at all, its bloody LOUD !!!
But not as loud as my old V8 Trials motor.
But why? Unless you need the utility of a Defender or the modular design of the body, the other vehicles are much better bets.True enough, but it’s not a Defender is it? That’s the thing, there’s something about Defenders (and previous versions) and nothing else will do.
The differences are much greater than sound proofing. The biggest difference is the Discovery uses a 1 piece body shell, that mounts on rubber isolating donuts to the chassis. The Defender mounts metal to metal on the chassis and the body is made up of many parts. There are however many other NVH enhancements on a Discovery above and beyond this.I think you will find that the noise levels in a Defender will depend on the quality of the sound-proofing rather than the specific engine fitted.
A 300tdi Discovery is a lot quieter than my 300tdi Defender, the mechanics are virtually identical but the Discovery has about an inch of soundproofing and carpet.
Either that or rotten floors and sills are really good at blocking noise.
The TD4 is a BMW engine found in the FreelanderI know...Disco/RRC similar and more comfortable....but it's not a Defender - don't know why I have this car but it is good to have one
So the TD4 is a bit quiter, I've heard from a TD4 2.2 driver that he can talk on a normal level on highway and radio is also on "normal" volume setting, because the 2.2 has some noise reduction factory fitted - is this true?
The question is: Is it worth to change to a TD4 2.2 or not? From lightnings perspective it is possible to get the noise level under control...my cruise speed is at 110kph (68mph). From my perspective i won't change the car because I like the TD5, the vent flaps and I've touched a lot of parts and I know what I have....
I'm not convinced, early 4-speed Range Rovers were pretty bloody noisy.The differences are much greater than sound proofing.
