The Jaguar XF has been a shot of adrenaline for the perpetually struggling leaping cat, as sexy lines and ample performance are adding new customers to the brand. We love the balance of the naturally aspirated V8 and the ample bite of its supercharged sibling, but we'll always be agreeable with the prospect of more power. Spy photos have shown us that an even more vicious feline is on the horizon with a blown 5.0L V8 that cranks out north of 500 ponies.

The folks over at Auto Telegraaf are reporting that the XFR will be unveiled at the Detroit Auto Show next January, which would give Jaguar a big introduction at North America's biggest auto show. We liked what we saw when the XFR made its cloaked debut at the Goodwood Festival of Speed (that graphic on the side should so be an option), and we're looking forward to seeing Tata's most powerful vehicle when it hits Detroit.
