It was 1968 when the XJ6 first burst on to the scene, envisaged by company founder Sir Williams Lyons as a four-door with the handling of an E-type. It has been a permanent fixture of the luxury saloon firmament ever since.
There have been eight generations over the half century, all, except the latest, low and sleek three-box interpretations of the first, with its signature grille and twin pairs of round headlights. The eighth-gen is, of course, low and sleek and, even today, daringly contemporary, and it is this that provides the basis for the new XJ50 celebration model.
Jaguar, these days selling more SUVs than saloons, has been restrained in its celebration. The XJ50 gets a modest going-over of bumpers, badges and blacked-out grille, with new wheels and, inside, quilted leather with embossed leaper logos. XJ50 is spelled out in the illuminated kick plates.
