The XF is one of the sportiest offerings among midsized luxury sedans. It's taut and agile yet possesses a supple and composed ride. The 340-hp supercharged V6 is punchy but maybe too growly for some. We got 21 mpg overall with our AWD version. A more powerful 380-hp version is also available. The front and rear seats are comfortable, and the trunk is large. However, interior ambience is a bit austere for a Jaguar, and the standard infotainment system is slow and somewhat fussy. The uplevel InControl Touch Pro system isn't much better. All models get a generous five-year/60,000-mile warranty, which includes free scheduled maintenance and roadside assistance.
