OK, I got to drive one today, a 2.0T rather than the 2.5T. Impressions were really positive. It isn't the engine I'd choose personally, though I'm sure my wife would find it excellent, it reminded me a lot of the Volvo 2.5 5 pot turbo when it was in its 177kw form rather than the current 185kw or whatever. It accelerates fine for daily use with a slight build up and surge, but having it come from the rear wheels is good.
The cabin is quite lovely. You sit low with the centre console comparatively high, and it is a nice driving position. The interior tech seemed much better than the 2012 XF, and far quicker as well. I didn't get to play with that much at all, but it seemed to me to be a big improvement.
The thing that struck me the most is how small the car felt to drive. The XF always felt like a big car, and the XK does as well. Even my wife's V40CC feels big. This felt tiny to drive, like an A class. But in a good way, like wherever you point the car that's where it will go - very tight. Essentially the same as an f type, but with your arse and spine remaining unbruised. Just awesomely good, better than any sedan I've ever driven.
And the ride was amazingly good. This one sat on 19"s, and I deliberately aimed for rough patches on the road to see how it felt - barely registered. Compared to the CC, it is light years ahead. It was as good as the XF on 19"s but handled better than the XF on 20"s.
So pretty impressive stuff. Still waiting to drive the 2.5T, but pretty convinced we will get one.
