Built to rival BMW's M5, Mercedes-Benz's E63 AMG and Audi's RS6, the new Jaguar XF-R looks every inch the true rival in these newly leaked official photos. The details that accompany the images indicate it will be a match in terms of power as well, rated at 510hp (380kW). The information leaked matches well with previous expectations. The XF-R has been no stranger to the spy camera, captured as recently as last week undergoing camouflaged testing. It is scheduled for an official debut in just a few days at the 2009 Detroit Auto Show, however, so it's not surprising that official images have emerged.
