Background
Jaguar took over the Daimler Company in 1960 and by body-doubling its Mk 2 as the Daimler V8-250, albeit with a smooth 2.5-litre V8 instead of the Jag’s straight six, sales could be increased at relatively minimal expense.
The Jaguar XJ6 of 1969 was such a wonderful car that even greater savings could be made. There was no need to fit a different drivetrain on the Daimler Sovereign version. Adding some flutes to the grille and changing some of the interior trim would do just as well.
Daimler’s heritage was even longer than Jaguar’s, so the Sovereign came across as slightly posher and more exclusive than the Jag. Having a real word for a name, and a regal one at that, added to the Daimler’s kudos – even if the Sov didn't have the Jag’s wood-capped doors.
It didn’t matter. In just about every other respect the Sovereign was an XJ6 – a game-changing luxury saloon that blew away the old idea that you could have grace or pace in a car, but not both at the same time.
Series II versions, with their raised front bumpers and shallower grilles, of both the XJ6 and the Sovereign arrived in 1973, as did an extended wheelbase model. Come 1975 and it was time to say goodbye to the 2.8-litre version of the XK engine, in favour of a new 170bhp 3.4-litre unit.
The Series III arrived in 1979 complete with more modern visuals, thanks to some clever tweaking that included a new grille, bumpers, roof and glasshouse, by Italian design house Pininfarina. Top-of-the-range Daimlers only, wore the Vanden Plas nomenclature until 1981, when a Jaguar version joined the ranks, with the name transferred between siblings and used on them exclusively from ‘83.
