The JLR group revealed the Jaguar Ftype and the new Range Rover recently. But they revealed the most powerful sedan ever made by the British manufacturer. Its powered by a supercharged V8 from the XKRS which produces 550 horses and 660 Nm of torque. Its going to get a tough fight from the BMW M5, Merc E63 AMG and the Audi RS-6. But with those stunning looks and good performance it surely wont be ignored.
