The biggest change in the XF diesel is not the exterior or the interior. It is in fact the new four-cylinder, 2-litre motor from Jaguar Land Rover’s Ingenium engine family. Developing 180bhp at 4,000rpm and 430Nm of torque between 1,750 and 2,500rpm, this all new engine will eventually find its way into other Jaguar Land Rover vehicles. Currently in the XF, it belies its modest capacity by offering fairly strong power delivery and a noticeable slab of torque down low. Yes, the turbo takes a moment to spool up but once on song, the engine spins freely and with a surprisingly deep rasp. In terms of power delivery, progress is soft at the bottom end, before giving way to that surging mid-range but tapering off quickly soon after. In manual mode, you can hold on to nearly 5,000rpm but there is no point pushing past 4,000rpm.

For most occasions, the four-cylinder Jag offers effortless performance. What’s more, the shifts from the ZF 8-speed gearbox are smooth enough to be imperceptible; however, there is some hesitancy to kick-down in D. That said, you can put the XF in Dynamic mode to make the throttle response crisper and the gearbox more engaging. With our Vbox timing gear attached, the XF diesel cleared up the 0-100kmph sprint in 9.31 seconds and took 5.39 seconds in 20-80kmph roll-on acceleration, making it decently quick for its size.
The XF is not a supremely quiet car, especially when compared to the E-Class or the A6 but around town it’s silent enough to have low-key conversations at ease. At highway speeds though there is noticeable tyre roar, more so over coarse-chip surfaces. Where the XF feels most effortless is exactly where you would expect it. It’s an ideal long-distance weapon and if you spend a lot of time doing inter-city runs, it’s a great companion – that 8-speed automatic really allows the XF tostretch its legs on the highway.

Riding on 55-profile Continental tyres, the XF diesel maintains the plush composure of its bigger sibling, the XJ when encountering bad roads. Although we are not saying it’s simply unfazed by sharp potholes and big bumps, the XF deals with road imperfections better than you might expect – the ride quality has a soft edge to it and unlike its predecessor, this new model will take pretty big jolts without letting in any form of unnerving clunks.
