The stunning new XJ has just broken cover, while, not long after launch, the XF received some welcome, if not entirely necessary, tweaks. Key to these fixes was the arrival of new diesels, including the hot S model. A fine example of having one’s cake and scoffing the lot, it offers hot–hatchbeating performance, while not embarrassing you on the CO2 scoresheet. Not much else changed, but not much else needed to – you get the same sleek exterior and dramatic interior, and a drive that will cosset or coax you, depending on your mood.
