The XK's steering, with speed-sensitive power assistance, is finger-light a low speed, the general refinement excellent, and the ride – for the most part – very accommodating. That said, the 20-inch wheels many Jaguar buyers will go for produce a stiff-legged reaction to potholes that the intermediate 19-inch rims largely avoid.
But the soothing nature of the XK is what characterises it. Even at a high-speed cruise it remains admirably quiet, and only an exaggerated roar on rough surfaces and some question marks over high-speed stability in crosswinds disturb the calm. Rolling refinement really is this car's USP.
Pick up the pace and the XK subtly responds. It’s not a car to pummel the road into submission in order to maintain body control. Instead, the low-speed suppleness persists, even on the generally firmer and more sporting models.
The standard XK proceeds as you hoped it might: gracefully and with a pleasingly feline athleticism over challenging roads. The sensation is less raw and less aggressive than you’ll feel aboard many of the XK’s rivals, but that far from restricts its pace.
The slightly vague ‘sneeze factor’ remains in the light steering around the straight ahead, but resistance builds consistently once you’ve turned through that phase and the wheel’s general weighting and precision are good on lock.
