Hi Haydn,
I guess you have gone for for the diesel engine, which is an updated version to meet EU6 regulations, and basically the larger version of the engine [2.7 diesel] that my s type has. A very good engine designed by Ford and Peugeot.
The style and design of Jaguar cars still shows some of the qualities of earlier Jaguars, and if you look carefully at the Jaguar F type -- sports car -- you will see similarities to the famous E Type of the sixties, and looking carefully at the XF you will see similarities with the s type of the eighties.
When the Mark 2 Jaguar was first shown, Bill Lyons [who was a Lancashire man] who founded Jaguar used the words "Grace, Pace and Space" and that really remains the motto of Jaguar.
Regards,
Peter.
