Excellent, thank you, it sounds like the D3 is just what I need. Is yours coil or air suspension?

Most days the loudest noise in my D3 is my Tinnitus!

My D3 was v. quite until I put a roof rack and Cooper STs on. Both of these add a dull roar to the car at 100kph.
The stereo covers it up nicely however.
The worst thing for road noise is when I put the awning on. That sounds like Darth Vader is on the roof.

I'll second that in my D4....except for the day I inadvertently drove over a creek wash-out....then there was a rather loud version of "ladies and gentlemen please brace for landing"
Interesting comment...... same in my D2. But.... the tinnitus is louder in the D2 than outside. I did some measurements. Audible noise at 100KPH is around 70dB, not bad at all. However, sub-sonic (inaudible) low frequency noise was around 95 dB!
Thus the inaudible low frequency noise still makes the tinnitus worse.
My single cab Defenders are bloody noisy - like about 80dB at 100KPH BUT the low frequency noise is only 85dB. Even without any hearing protection, I get less tinnitus in the Defenders.
It's all getting a bit complicated......

Off topic i know, but which awning and what racks are you using.

Can't talk for the others but it has been noted by many that have gone to places like the Arctic...which is really quiet when there is no wind...tinnitus is really obvious....
I was referring to how quiet it is in the D4 cabin....exaggerating a bit thou...but it is quiet.

One of the reasons I choose a D4 over a fairly new D3 was that the D4 was that little bit quieter. It is a very relaxed crusiser, on the open road I am amzed at what is probably only a small difference in sound levels can do after 8 hrs of driving. It is the only car i have driven for long periods and felt like I have been sitting in the lounge room the whole time. It is a pleasure to cruise in especially when the kids and SWMBO are asleep.

As a fellow tinnitus sufferer, I originally got a V8 D3 for this reason. The engine was suprisingly economical unless driven hard or fast, which helped encouraging me to drive at a quiet 105 km/hr. The only intrusive noise when not driving floored was when driving on very "open pore" bitumen. New road tyres are the key to keeping road noise down, in my experience. In general the D3/D4 it was about as quiet as anything I've ever been in (except the front top deck of an Airbus A380). The A/C of any vehicle on full roar can be noisy, but if you get the rear A/C, running it at a faster speed than in the front quiets things down more. Items on the roof make noise no matter what, although the official LR cross bars were pretty quiet.
My current 3.0 D4 is nearly as quiet as the V8 D3 was at high speeds, but there's more diesel rumble in the city. I have an aftermarket roofrack which causes tinnitus-inducing roof vibrations, but have managed to quiet that a bit with some 4" plastic pipe inelegantly stuffed in the front. Or I just go through the hassle of taking the rack off for town drives. On my D4 the air suspension compressor is much quieter than it was on the D3, which makes a difference to the tinnitus.
Of course all this is swamped by the effect of SWMBO but that's a small price to pay (okay, mine did radio work for the ABC decades ago and can talk clearly, loud and fast).

I drive an assortment of 4WD's in any one week. The D4 is a stack quieter than everything else. The Landcruiser 100 & 200 are very good but not in the same league for interior noise. Patrols are quite noisy as are the diesel Pajero's. However, put a a genuine LR Expedition rack on the D4, and you will have an intrusive roar at 100kmh. I have shut it up to an acceptable level, using a piece of shaped poly pipe, covered with a rubber steam insulation. As with Dingmark Jim above .
