In addition to the new XJR, Jaguar also arrived in Manhattan this year (2013) with the most extreme XK to date. The XKR-S GT packs the same 550-horsepower 5.0-liter supercharged V8 as the existing XKR-S (not to mention the aforementioned XJR and the XFR-S sedans), but upgrades with revised suspension, brakes, rolling stock, aero and more to make us forget that Jaguar ever had to play second fiddle to Aston Martin. It’s the first roadgoing Jaguar to use carbon-ceramic brakes, and also features adjustable dampers and active exhaust system, but the price tag jumps to $174,000 for each of the 30 units that will reach North America.
