The Jaguar XF is another splendid addition to the models made available by Jaguar. It is a luxury executive vehicle and it is not hard to tell, the interior gives the feel of a posh, classy office which would be a privilege to sit in let alone drive. It gives you a smooth ride and eliminates much if not all of the noise from the outside world. For these reasons the Jaguar XF has won the What Car? Best Executive Car four years in a row from 2008 to 2011! Pretty impressive seeing as it was only introduced in 2008. When it comes to engines the XF shares the same ones as the XJ with the addition of a 2.2 litre diesel for the more eco conscious.
