A whole world separates the Jaguar S-Type from its successor, the attractive XF, which could be considered as one of the most beautiful sedan in the world. Designer Ian Callum has created the XF from the XK's characteristic attributes. The sedan is powered by a powerful 300 horsepower 4.2-litre V8 engine, while the optional turbo engine produces 420 horsepower. Its interior is that of a prestige sedan wanting to recover its status.
