Silly question but (for once) I'm being serious.
If you live in Norfolk then you can ignore this topic.
Living in the south west however means lots of big hills, and therefore the ability to go up them is quite handy.
I was being passenger driven in a (I think) 150 TDI which a friend had on loan for a couple days and it really struggled with a couple of biggish hills in top gear (dual carriageway, A380 split at Telegraph Hill which anyone who's been to Torbay will have had to conquer).
Now I'm sure the mk6 GTD's I drove went up it pretty smartly and I know a couple of remapped Diesels I had years ago struggled a little on that hill and fared badly pre-remap.
With the prodigious torque of modern diesels I was a bit surprised the more modern car didn't like the hill, and it reminded me of the 140 TDI Cabrio I had for a week in October/November while mine was in for service, which really didn't like big fast hills in top gear. Obviously higher gearing offsets the torque figure a little but GTD's always feel very punchy through the gears and even the Cabrio went well on flat roads.
So, with 280 lb ft of grunt, how do GTD's cope with steep high speed hills?
Funnily enough a GTD passed us a bit later at break neck speed but that was on a better bit of road.
Obviously with a tuning box or map the GTD should eat hills like they're not there but I'm curious as to how the standard car copes.
