Ok, wading depth is where the Disco trumps it (580mm vs 700) but it’s not really something I ever plan on taking to its limit. Water scares me a lot.
Both cars are air suspension, are independent and have anti roll bars, so the articulation is basically the same from the limited off-roading I have done.
The Touareg comes with proper locking centre and rear diffs, whereas the Disco had just a locking rear which was an optional extra. The disco does have JLR’s terrain response though, and they’ve kinda been doing that for a long time
Touareg has a slightly smaller approach angle, but a better departure.
I think saying every metric ahead is wrong (much like me saying it’s better in every way), but consider the whole package. The engine and box are better, they don’t rust, the compressors and pumps don’t fail and or leak, and you don’t need to take the body off to replace the EGRs
D3 and D4 drive like tanks on the road, as opposed to this which is just like driving a big Golf. Most of them did come with coil springs, some with ‘low profile tyres’ and they do ride harder. If the D4 had the Touareg drivetrain and engine, it would be the best car ever.
