Predecessor Rolls-Royce Wraith
Successor Rolls-Royce Silver Cloud

The Rolls-Royce Silver Dawn is a full-size luxury car that was produced by Rolls-Royce at their Crewe works between 1949 and 1955. It was the first Rolls-Royce car to be offered with a factory built body which it shared, along with its chassis, with the Bentley Mark VI until 1952 and then the Bentley R Type until production finished in 1955. The car was first introduced as an export only model. The left hand drive manual transmission models had a column gear change, while right hand drives had a floor change by the door. In the British home market the Silver Dawn only became available from October 1953, with the introduction of the model corresponding to the Bentley R Type. [3]

History

In 1944 W. A. Robotham saw that there would be limited postwar demand for Rolls-Royce or Bentley chassis to be fitted with bodies from specialist coachbuilders, and negotiated a contract with the Pressed Steel Company for a general-purpose body to carry four people in comfort on their postwar rolling chassis, fitted as always with a distinct Rolls-Royce or Bentley radiator. Though he stretched the demand to 2000 per year, Pressed Steel were "nonplussed" by the small demand. [4]

A mere 760 were produced between 1949 and 1955. Silver Dawn Series A-D had bodywork identical to the Mark VI. In 1953, with the "E" series (Chassis Number SKE2), the Silver Dawn body was modified in parallel to the Bentley Mk VI body and a large boot was added. [5] While the Bentley Mk VI was renamed the Bentley R after this change, the Rolls-Royce Silver Dawn kept its name. Even with mass produced Standard Steel bodies, all panels forward of the bulkhead/firewall were slightly different for the Rolls-Royce to those fitted to the Bentley.

Technical description

In 1951 the Silver Dawn was upgraded to the 4 1/2 L engine and the full flow oil filter (Chassis Number LSFC2). In 1953 the high compression cylinder head was fitted from Chassis number SMF66 and from the same chassis number on the Bentley Mk VI type camshaft was fitted to left hand drive vehicles. [6] Earlier models up to circa May 1954 had a different fascia from the Bentley Mk.VI and 'R' Type, and were fitted with a single exhaust system. Later models from the SRH2 chassis series had the Bentley style fascia and the twin exhaust system, as fitted to the Bentley 'R' Type.

The inline six-cylinder engine had overhead inlet and side exhaust valves and had a capacity of 4,257 cc (259.8 cu in) until 1951 when it was enlarged to 4,566 cc (278.6 cu in). The carburettor up to Chassis number SFC100 was a single double downdraught Stromberg type AAV 26 until 1952 when it was replaced by a Zenith DBVC42. [1] [7]

A 4-speed manual gearbox was fitted to all cars at first, with a 4-speed automatic becoming an option in late 1952 on the 'E' Series chassis, and on the corresponding Bentley R Type chassis. There are conflicting reports if the automatic gearbox became standard in the Silver Dawn, but both manual and automatic options were available until the end of the production run. [8] However the original invoice for a 1955 UK model (Chassis Number SVJ115) clearly shows that the Automatic Gearbox was an optional extra and cost the buyer £70.0.0.

The suspension was independent at the front using coil springs while at the rear the live axle used half elliptic leaf springs. The car had a separate chassis made with traditional riveted construction until 1953 after which it was welded. Servo assisted 12.25 in (311 mm) drum brakes were used, hydraulically operated at the front but retaining mechanical operation at the rear. Although many cars were fitted with factory built bodies, others were supplied to external coachbuilders.

Performance

A factory bodied Silver Dawn with automatic transmission tested by The Motor magazine in 1954 had a top speed of 94.0 mph (151.3 km/h) and could accelerate from 0-60 mph (97 km/h) in 15.2 seconds. A fuel consumption of 15.4 miles per imperial gallon (18.3 L/100 km; 12.8 mpgUS) was recorded. The test car cost £4704 including taxes. [2]

The Rolls-Royce Silver Cloud is a luxury automobile produced by Rolls-Royce Limited from April 1955 to March 1966. It was the core model of the Rolls-Royce range during that period. The Silver Cloud replaced the Silver Dawn and was, in turn, replaced by the Silver Shadow. The John P. Blatchley design was a major change from the pre-war models and the highly derivative Silver Dawn. As part of a range rationalisation, the Bentley S1 was made essentially identical, apart from its radiator grille and badging.

The Bentley S1 was a luxury car produced by Bentley Motors Limited from 1955 until 1959. The S1 was derived from Rolls-Royce's complete redesign of its standard production car after World War II, the Silver Cloud. Each was its maker's last standard production car with an independent chassis. The S-series Bentley was given the Rolls-Royce - Bentley L Series V8 engine in late 1959 and named the S2. Twin headlamps and a facelift to the front arrived in late 1962, resulting in the S3. In late 1965, the S3 was replaced by the new unitary construction Rolls-Royce Silver Shadow-derived T series.

The Bentley R Type is the second series of post-war Bentley automobiles, replacing the Mark VI. Essentially a larger-boot version of the Mk VI, the R type is regarded by some as a stop-gap before the introduction of the S series cars in 1955. As with its predecessor, a standard body was available as well as coachbuilt versions by firms including H. J. Mulliner & Co., Park Ward, Harold Radford, Freestone and Webb, Carrosserie Worblaufen and others.

The Bentley was also available as a chassis for coachbuilders, but for the first time could be bought with a Rolls-Royce built Standard Steel body. The use of the name "wraith" coincided with the established tradition of naming models after "ghosts".
