Sounds like basic physics. 26 degree angle while lifted with air may cause car to tip in turn situations. Are you finding that the approach at 24 only occurs with air activated?; Perhaps the approach increases to 26 when the car is lowered to the ground? Wild guess.

Should the approach angle not decrease when lowered?
I would guess that VW would give us the best figures they can so I guess that at 300mm it has an agle of 24, and at 230mm 26. Very funny physics

I have tried the dealer....:confused:

Nothing to do with tip in or anything like that.

Wrapper, here in Aus we can order as a no cost option the off-road pack. This changes the skirts all the way around, exhausts (I think just the tips to ovals, affords underbody protection by way of a skid plate etc. This has the potential to change the approach angle but I noticed in their brochures it doesn't. It may do in SA though???

Hi
New to this forum, so hope I am posting in the right place.

Looking at buying a Touareg V6 TDI, can anybody tell me why the Touareg with Terrain Tech has more ground clearance than the standard one if the tyres and rims are the same size?

The t tech Touareg has 230mm ground clearance with a 26 degree approach angle, but the normal one with air suspension has 300mm clearance but only 24 degrees approach. how does this work? I do understand that the air Susp. only raises the body from the axles but this still does not seem right

please help.

I am referring to my T2 sales brochure, but the same logic probably applies.
Steel suspension 237mm ground clearance with Approach/dept angles of 28.4 & 28.1degrees.
Air suspension has 300mm max ground clearance, but 'normal' road level is only 215mm. This provides for the lesser Approach/dept angles you have probably seen.
At max (300mm) the angles are quoted as 33.2 & 33.6degrees.
Cheers, Dub

Hi
I agree with you but look at our brochure. The steel suspension 220m 22 degrees. If you are right and the approach angles are stated at the lowest suspension setting how come the one with air suspension @ 215mm has 24 Degrees. somewhere something does not make sense. But I think I am happy with the answer that it has a different belly plate and more under body protection(terrain Tech), that's what I want. will just need to wait for the right one.

Wapper - Rather confusing isn't it.
The way I read your brochure:
Standard 220mm is 22/23deg
Air normal setting is 24/25deg
Terrain Tech clearance increases to 230/235mm which gives 26deg
Terrain Tech with air at max setting (300mm) is 33/33deg.

Good luck with your search/purchase.

To further 'muddy the water' concerning air suspension heights, the figures for T3 air suspension are different to those for T1/T2: Following are T3 figures [T2 in brackets] taken from Touareg Self Study Guides

Level 1 (Load) : 147mm [160mm]
Level 2 (Hi-speed and if 'Sport' damper control selected when in Level 3) : 172mm [190mm]
Level 3 (Road level) : 197mm [215mm]
Level 4 (Off-road level) : 245mm [240mm]
Level 5 (X'tra level) : 300mm [300mm].

Perhaps I should get out my tape measure?

Not sure what underbody protection RSA terrain tech option has, but Aussie 4XMotion (T3 'offroad' option) underbody protection is not exactly 'tough'. Front belly plate is plate steel (but less than 2mm) - and from experience of getting 'hung up' on a tree stump in a paddock, it can bend/buckle rather than support the full weight of the vehicle. The other underbody protection that sits rearward of the belly plate is nothing more than a plastic stone guard whose primary function (as written in the technical literature) is to provide noise suppression.

If you want proper underbody protection for your Treg, I expect you will need to find customised after-market solution or build yourself.

OK, just measured various levels +/- 5mm at rear end of front strut:
L1 = 160mm
L2 = 190mm
L3 = 220mm
L4 = 245mm
L5 = 275mm (not the claimed 300mm).

Note my Treg is shod with 245/65R17 (almost new) with OD = 754mm.

A dealer did some research for me and said that the bumpers has a more robust design on the terrain tech package allowing for the increased approach angles.:|

Bumpers have a more robust design? Seriously? Can you post a pic of said bumper as it would have to be OEM and I find it hard to believe that SA Is the only market for them.

I unfortunately live in a small town and the closest Terrain tech Model is 800km away. The word that dealer used was "more aggressive bumper"
This is a picture I found on Auto Trader

Hi all. I know this an old thread but here is Volkswagens explanation of "Terrain Tech":


For the serious off-roader, the 4xMotion Terrain Tech Package (optional only on the
3.0 V6 TDI) is designed to tackle even greater off-road challenges with a more rugged transfer
case designed for effortlessly tackling the toughest territory. Features include reduction gearing
and centre and rear differential locks, each with up to 100% locking of power to the wheels. This
provides a climbing ability of 45° and a fording depth of 580mm, with air suspension


It does not look like its got anything to do with ground clearance and the approach angle. If the approach is less on a certain model it will have something to do with the design of the front bumper. Meaning the overhang will be a bit shorter for the model with higher approach angles. Air suspension will slightly increase the angles.

Hello, I have the spanish Terrain tech version.

As I read above, is 1cm higher on the front axel and 1.5cm higher on the rear axel, this is due to the 4X gear box which is bigger than the normal one.
Fuel capacity increases from 85ltr to 100ltr in this model and it is more capable in off road trials.
