The VCU 4x4 system is simple, there are just a few fundamental principles you need to be aware of.
Number 1: When ewe is on full lock all four wheels is turning at different speeds. This is why full time 4x4's have massive turning cicles as else them's transmission would melt.
Number 2: The Freelander's rear diff ratio and the IRD ratio (similar to yer tratter's transfer box) is different. This is to take up the lag when your front wheels start to slip so that the VCU engages quicker and you get power to the back wheels when you needs it.
Number 3: Because of this system the Hippo is much more "car like" in the way it handles, which is why many of us like it. As a daily driver it feels very civilised.
Number 4: On the Hippo 2's ewe have them new fangled Haldex units wot likes to break alot. They allows you to select 2wd, 4x4 auto or full time 4x4. The Hippo 1 is basically in the second mode at all times, which for the most part works just fine.
