Well we have a disco 2 TD5 and if you ask me they are extremely underpowered unless you drive them ie keep them up at 1700 rpm and they are ok we bought ours so the wife could tow the horsebox with it but it does struggle compared to our touareg.we are looking at getting it chipped which should make a massive difference,we are going to use Bell auto services and i am lead to believe he does the chips for other companies as well ie twisted.
