The 1965-80 T Series Bentleys replaced the S Series, they were Bentleys version of the Rolls Royce Silver Shadow, technically identical, the Bentley had slightly lower bonnet and a simpler and lighter grille. The newly designed T Series Bentley and the Silver Shadow Rolls Royce got many new features such as disc rather than drum brakes, and independent rear suspension, rather than the outdated live axle design. In 1977, the model was updated the T2 Bentley and the Silver Shadow II in recognition of several major changes, most notably rack and pinion steering, bumpers were changed from chrome to alloy and rubber and the small grilles mounted beneath the headlamps were deleted.
