If you liked the new Jaguar XKR-S Convertible in pictures, you are going to absolutely love it when you see it in action in these videos and hear that V8 engine. That is the sound of 550PS (405kW) and 502lb/ft (680Nm). Thanks to the tower of power this handsome convertible becomes the fastest open-top Jaguar, and indeed one of the fastest convertibles in the world, with a top speed of 186 mph (300 km/h). It’s a 100 grand car this, but it’s worth every single penny.
