Bentley S1 and Bentley S1 Continental
(1955 - 1959)

Bentley S1, 1958, #B403FD, Harold Radford Countryman
Bentley S1, 1958, #B403FD, Harold Radford Countryman. The special shape of the bootlid betrayes this one as a Harold Radford Countryman version.

A close inspection of the Bentley S1 left no doubt that Rolls-Royce had decided to restrict differences between the Silver Cloud I and the Bentley S1 to radiators and badging as there were no differences technically. The models shared the straight six cylinder F-engine with 4,887 cc now in its final stage of development. The body lines lent themselves to two-tone paintwork and usually on the Bentley S1 the bonnet top was finished in the lower colour (experts know that the side moulding on the Bentley bonnett doesn't run up to the radiator edge as the one on the Silver Cloud model does). The mildly tuned Bentley S1 Continental was added within six months after introduction of the new model. This brisker performing variant distinguished itself by not being available with a standard coachwork; customers had to select an appropriate one from the choice offered by specialist coachbuilders.
