You can't help but notice the Jaguar XKR-S. But that's entirely the point; it's the most outlandish, most-powerful and most focussed sports car the famous British car maker has ever produced. And it certainly doesn't want all of that to go unnoticed. With a potent 405kW supercharged 5.0-litre V8 nestled under its long, sleek aluminium-crafted nose the XKR-S takes the grand touring coupe formula to another level. It's still mighty comfortable and is an absolutely effortless cross-country bomber, but let the cat off the leash and the Jag transforms into a wild track-honed weapon.
