Bentley R-Type

The successor to the Bentley Mark VI R-Type was sold by Bentley in 1952 as the second series-production car after the war. During development, the models were labeled under the Name Mark VII. In common speech, however, they were taged as R-Type Models according to the RZ chassis number stamping.


The first post-war Mark VI models were critizized because of their small trunk and the competitors could come up already with much more spacious tail sections, so the trunks of R-Type models were adjusted to gain more space. The result was a trunk lid made of lightweight aluminum and more space for 4 large and 2 small suitcases (instead of the 2 large and 2 small suitcases in the predecessor). And now it was also convenient to stow away two golf bags.

Apart from that in the standard steel saloon models shown here the chassis is made of cold-formed steel on a steel tube frame. As before World War II, some R-Type models were fitted with special bodies such as the Mulliner, Freestone, Webb, Radford or others.

By the way, the R-Type models are still listed in the papers under the name-Rolls Royce, because Bentley is standing since 1931 under the patronage of Rolls-Royce and the R-Type models are in every aspect, except the radiator and the hood, identical to the Rolls-Royce Silver Dawn and the later E Series models.

It is powered by a 4.6-liter in-line six-cylinder engine. The technology of this engine was game changing at these times. A water-cooled cast-iron motor block with an aluminum cylinder block, a bore of 92.08 mm and a stroke of 114.3 mm brings the vehicle smoothly up to 164 km/h top speed. Heat problems are unknown for a well-maintained engine. Mixture preparation takes place via two SU-H6 carburettors.

A 4-speed automatic transmits the driving force to the rear wheels. This automatic was also used in the successor models.

The suspension consists of individually suspended wheels on coil springs on the front axle and a rigid axle at the rear, with semi-elliptical leaf springs on each side. On the front wheels act hydraulic drum brakes on the rear wheels mechanical cable brakes which are controlled via a servo cable from the transmission.

Inside rules British solidity. In order to protect the passengers in the rear from the sun or unloved eyes, a sunblind can be closed from the driver’s side at the rear window.

The R-Type models were built in the period from 1952 to 1955.
