There’s always been a sort of fluidity to the ride and handling compromise of modern Jags, and if anything the new XF has enhanced this further. It feels quite firmly sprung, but the damping keeps it from jarring over anything but the most punishing potholes, and there's no unflattering post-bump wobble or shudder form the body, giving the XF a ruthlessly composed yet supple feel over all sorts of surface intrusions. Even big, low speed bumps are smoothed over easily, and expansion joints and the like are more heard than felt.
This well-resolved damping also helps the tyres maintain consistent contact and grip levels with the road, even over fast mid-corner yumps, which in turn brings confidence to the light-footed handling even over scrappy-feeling country roads. Together with the organic-feeling steering, the Jag is a car that keen drivers can really revel in, yet is also easy to judge in a tight spot, and generally enjoyable even in the sort of awkward, traffic-clogged ebb and flow that's often the reality of driving in the UK.
The powertrain is no hindrance to any of this. Step-off is smooth and predictable, with the eight-speed auto keeping the V6 in a satisfyingly effortless mid-range mooch. Is it the most refined six-cylinder in the class? Not really, and nor is it the most intuitive gearbox, with the odd unexpected heartbeat of a pause just when you don’t want it if you’re dallying with Sport mode.
Still, there's masses of mid-range urgency, while engine noise isn’t bad unless you really rev it out, road noise is well suppressed and there’s very little mechanical vibration, so this remains a refined exec that would have you feeling fresh even after many hours of motorway slog.
An excellent driving position is a big part of that, too. The XF S gets full electric adjustment including tilt and four-way lumbar adjustment as standard, plus a seat that drops as low as anyone could want. Heated front seats and suitably top-notch leather, plus various driver aids including traffic sign recognition and automatic emergency braking, complete a pretty comprehensive standard spec.
It’s just a shame that the general perceived interior quality is still a touch behind that of Audi and BMW, let down by details such as the slightly clicky stalk movement, the fairly aged graphics on the (optional) head-up display, and some unfinished-looking wiring and seat-back release buttons tacked into the boot.
The colour touchscreen, complete with nav, is perhaps a touch slow to respond and not as easy to muddle through as the best rotary-controlled alternatives, but key functions are really easy to access and adjust, and with time it's easy to get on with this system. A fairly stonking, 10-speaker Meridian sound system and every method of media or phone connectivity you could want also means the Jag will satisfy audiophiles.
Rear passengers might feel that it’s a bit dark in the back, since the tapering windowline cuts out the light a bit, but there’s actually more leg room than in a BMW 5 Series, and not much less head room. A broad seat base offers loads of thigh support, too, so even lanky passengers will be fine in the back.
The boot is on a par with most rivals', and you get standard split-folding rear seats so you can actually squeeze a 2.0-metre-long item into the XF, provided it fits through the narrow, letterbox-shaped opening leading from the boot into the main cabin area.
