I think some owners who might be contemplating buying a mk4 may be concerned about the hybrids ability to climb and descend steep hills.
I have commented in the past how IMO it climbs long continental alpine passes easily, and long descents are no problem even in D mode. Albeit maybe a bit noisier than usual when working hard or having to use its ICE for engine braking, rather than generator magnetic drag.
I have recently been able to put it through its paces in North Yorkshire , where hills can be very steep, although generally quite short. But probably as challenging as any you could find in the UK . Indeed I said to Mrs LV (in a fake Yorkshire Accent) "Eh Yup Lass, this is like the alps only steeper"

I went up and down Sutton Bank (on the A170 near Thirsk) several times. This is 25% ( 1 in 4) . No problem at all Up or down . It is quite short - only about a mile or so. Two passengers
Also several other roads signed as 20% (1 in 5) and I made hill starts on quiet roads with undulating hillocks that must be at least 25% for a few metres.
IMO UK owners should have no concerns , or indeed elsewhere in Europe.
Amazing how many road kill pheasants we saw . By coincidence we heard a discussion on the radio next day that the number of Pheasant chicks raised and released for shooting income has increased from just a few million to 50 million a year in recent years

Needless to say the opinions on this were heated.
