Jaguar introduces two all-new engines for the 2013 XF: a 3.0-liter supercharged V6 and a 2.0-liter four-cylinder. Both are meant to offer buyers better fuel efficiency than the existing V8. The XF also gets another significant new piece of equipment for 2013: optional all-wheel drive. Finally, all 2013 XFs get a new eight-speed automatic transmission, while a standard stop-start function for the V6 and V8 engines also helps save fuel.

Midsize sedans, even those from premium automakers, can have a certain me-too kind of presence. Usually, there's only so much designers can do, or have been willing to do, with a four-door sedan aimed at generally conservative and cautious buyers. But the 2013 Jaguar XF happens to be a pleasant exception. With a design presence and air of exclusivity, the XF makes an impression that its more mainstream rivals struggle to replicate.
