Plenty of broken/collapsed coils to be found out there.

Nothing, absolutely nothing, makes up for an owner who won't do preventative or scheduled maintenance.

"EAS is a proven KISS component" sorry thats a stretch in a 4x4.

Ive had both and there are a huge amount of things that can go wrong with air susp
1. Bag puncture
2. Bag failure
3. Airline leak
4. Compressor failure
5. Air Susp Computer Failure
6. Air susp height sensor failure leading to comp failure and even limp home modes.

Yes you may say i carry spares for all of the above, have a fault clearer for everything but there is no way that air is more reliable or even remotely close to as reliable as coils or can even be refered to as "keeping things Simple"

I have had both and know first hand what is more reliable.

Coils only break or colapse if you 1 put the wrong coils in for the work you are doing, 2 overload your coils or 3 have old coils that are fatigued.

Most Broken Coils can be fixed with 4 good quality stainless hoseclamps or welded with a few small pieces of metal using your dual batterys ..not that ive ever heard of it happening to anyone I know

I agree the newer Land Rovers and Range Rovers air systems seem to be far more reliable then days gone by and you can increase reliabilty of any air system with a proactive maintainence schedule and i even tell people how reliable they are now and outback friendly etc etc..however air susp will never be as reliable as coils..Landrover knows this and thats no doubt why they are supplying the cars that will most likely hit remote environments and tuff work with a Coil option Namely the Disco 5 and the Defender (when released)

Air is a reliable system on a newer landrover..however coils will always get you further with less drama. Its just a question of are you willing to give away the enless list of benefits of running an air system for that extra reliabilty of coils.

The only person that can answer that is the person buying the car.

Why would you want coils with independent suspension? At least with EAS you get cross link valves.. coils have a lot less articulation

Ask any outback driver or KOH driver. As above there is no doubt the list of benifits of air suspension is long. Unfortunatly being more reliable than coils is not one of them neither is it keeping things simple when choosing to run coils or air..will the defender have a air susp option? Most likely. Will the Air Susp be awesome? Yes. Will the air susp option be more reliable than coils? No

Well why not go all the way back to leaf springs then? About as much articulation as coils on independent suspension

And steel wrapped cart wheels - rather then those pesky
Pneumatic rubber things

Leaf springs dont work to well with the independent scenerio which is used for safety and comfort..LR3 +2 coil/air front gives same flex,rear you get more from air.
Hopefully Landrover sort out the independant flex issue with the new Defender.

Simple yes but not strong enough to withstand 3 tonne and not capable of or comfortable at 110kph, you also have zero grip up a hill...even the all rubber(no air) wheel/tyre combo wont work for the simple fact they fill up with mud, back to the drawing board Tombie

No need. I spend a lot of time driving in the bush - on my air suspended D4..
Even used on mine sites... where the Power Trains all run - Airbags... and the LVs regularly collapse struts/springs/leafs

Coils have a life, Bags have a life - the D3/4 bags are well armoured and unlikely to suffer a stick injury.

If the bags are replaced as part of an effective service schedule they won't let anyone down

Add to that - regardless of coil or air... you can always limp home...
