Jaguar's flagship sedan gets the 550-horsepower engine from the XFR-S to bring the XJR back to the forefront.
Back in the day, the XJ was the Jaguar sedan of choice. But these days Jag has the XF as well, and a new XS on its way. So while the XJR may have held the British performance sedan crown decades ago, that role has since fallen to the XFR. But now Jaguar has announced the new XJR, which it will debut next week at the New York Auto Show. Slotting in above the 470-horsepower XJ Supercharged and 510hp XJ Supersport, the new XJR takes its blown 5.0-liter V8 with 550 horsepower from the XFR-S and XKR-S performance models.
Jaguar isn’t saying much about the XJR at this point, only that it will be “the most focused, agile and responsive Jaguar XJ ever made”, combining “supercar performance and assertive looks with the highest levels of luxury”. By comparison, the soon-to-be-replaced Mercedes-Benz S63 AMG packs 14 less horses at 536, Audi’s S8 packs 30 less at 520, but the RS7 has 10 more at 560. Maserati’s new Quattroporte, meanwhile, offers up to 523 horsepower with the twin-turbo V8, making it 27 horsepower less powerful than the new XJR.
