The Jaguar XF only arrived in 2008, but in just three years, it has reset the course for a brand that was hobbled by the transgression of the X-Type and a beloved but aging XJ. In 2010, it received a new set of engines that delivered performance on par with the promise of the concept car, and now, for 2012, we have a car that delivers on the looks of that showstopper. Jaguar has revealed a refreshed XF at the New York Auto Show, and the renew isn’t ostentatious, but it is thorough, and rewarding.
