When the Barra was in development Jaguar were in the midst of replacing their I6 with the V6.
From memory the Barra valvetrain and combustion chamber design was actually copied from the Duratec V6 used in the Jag S type. Used that basic setup and adapted it to suit. If I can remember that correctly.
