Bentley R Type#R-Type Continental

Other than the radiator grilles and the carburation there was little difference between the standard Bentley R Type and the Rolls-Royce Silver Dawn. The R Type was the more popular car. Some 2,500 units were manufactured during its run, as compared to the Silver Dawn's 760.

During development it was referred to as the Bentley Mark VII; the chassis cards for these cars describe them as Bentley 7. The R Type name which is now usually applied stems from chassis series RT. The front of the saloon model was identical to the Mark VI, but the boot (trunk) was almost doubled in capacity.{{Citation needed|date=October 2014}} The engine displacement was approximately 4½ litres, as fitted to later versions of the Mark VI.{{Sfn|Culshaw|Horrobin|2013|p=83}} An automatic choke was fitted to the R-type's carburettor. The attachment of the rear springs to the chassis was altered in detail between the Mark VI and the R Type.{{Sfn|Bennett|2009|p=17}}

For buyers looking for a more distinctive car, a decreasing number had custom coachwork available from the dwindling number of UK coachbuilders. These ranged from the grand flowing lines of Freestone and Webb's conservative, almost prewar shapes, to the practical conversions of Harold Radford which including a clamshell style tailgate and folding rear seats.{{peacock inline|date=October 2014}}

All R Type models use an iron-block/aluminium-head straight-six engine fed by twin SU Type H6 carburettors.{{Citation needed|date=October 2014}} The basic engine displaced {{Convert|4566|cc|cuin|abbr=on}} with a {{Convert|92|mm|in|2|abbr=on}} bore and {{Convert|114.3|mm|2|abbr=on}} stroke.{{Sfn|Culshaw|Horrobin|2013|p=83}} A four-speed manual transmission was standard with a four-speed automatic option becoming standard on later cars.

As of 2017, it remains the last car by Bentley to be sold which has manual transmission.

The suspension was independent at the front using coil springs with semi elliptic leaf springs at the rear.{{Sfn|Culshaw|Horrobin|2013|p=83}} The brakes used {{convert|12.25|in|mm|0|abbr=on}} drums all round and were operated hydraulically at the front and mechanically at the rear via a gearbox driven servo.{{Citation needed|date=October 2014}}

The first example is the standard steel saloon built by Bentley, but a number of customers opted for a bare chassis which was taken to a coachbuilder of their choice.

A four-door saloon with automatic transmission tested by the British magazine The Motor in 1953 had a top speed of {{convert|101.7|mph|km/h|abbr=on}} and could accelerate from 0-{{convert|60|mph|km/h|abbr=on}} in 13.25 seconds. A fuel consumption of {{convert|15.5|mpgimp|L/100 km mpgus}} was recorded. The test car cost £4481 including taxes.{{cite journal |title = The B7 Bentley with automatic transmission| journal =The Motor| date = 14 October 1953}}

{{For|the R-Type's successor|Bentley S1 Continental}}

The R-Type Continental was a high-performance version of the R-Type. It was the fastest four-seat car in production at the time.{{Sfn|Egan|1990|p=120}}

The prototype was developed by a team of designers and engineers from Rolls-Royce Ltd. and coachbuilder H. J. Mulliner & Co. led by Rolls-Royce's Chief Project Engineer, Ivan Evernden.{{Sfn|Bennett|2009|pp=13–14}} Rolls-Royce worked with H. J. Mulliner instead of their own coachbuilding subsidiary Park Ward because the former had developed a lightweight body construction system using metal throughout instead of the traditional ash-framed bodies.{{Sfn|Bennett|2009|pp=11, 14}}

The styling, finalised by Stanley Watts of H. J. Mulliner,{{Sfn|Bennett|2009|pp=14–15}} was influenced by aerodynamic testing conducted at Rolls-Royce's wind tunnel by Evernden's assistant, Milford Read. The rear fins stabilised the car at speed and made it resistant to changes in direction due to crosswinds.{{Sfn|Bennett|2009|p=15}}

A maximum kerb weight of {{Convert|34|long cwt|kg lb}} was specified to keep the tyres within a safe load limit at a top speed of {{Convert|120|mph|km/h|abbr=on}}.{{Sfn|Bennett|2009|p=16}}

The prototype, with chassis number 9-B-VI{{Sfn|Bennett|2009|p=16}} and registration number OLG-490, which earned it the nickname "Olga",{{Sfn|Bennett|2009|p=17}} was on the road by August 1951.{{Sfn|Bennett|2009|p=16}} Olga and the first series of production Continentals were based on the Mark VI chassis, and used a manual mixture control on the steering wheel boss, as these versions did not have an automatic choke.{{Sfn|Bennett|2009|p=17}}

The early R Type Continental has essentially the same engine as the standard R Type, but with modified carburation, induction and exhaust manifolds along with higher gear ratios.{{cite journal |title = Used Car test: Bentley Continental| journal = Autocar | volume = 130 | issue= 3824 | pages = 47–48| date = 29 May 1969}} The compression ratio was raised to 7.25:1 from the standard 6.75:1,{{Sfn|Culshaw|Horrobin|2013|p=83}} while the final gear ratio was raised (lowered numerically) from 3.41 to 3.07.{{Sfn|Egan|1990|p=121}}

Despite its name, the two-door Continental was produced principally for the domestic home market, most of the 207 cars produced were right-hand drive, with 43 left-hand drive examples produced for use abroad. The chassis was produced at the Rolls-Royce Crewe factory and shared many components with the standard R type. R-Type Continentals were delivered as rolling chassis to the coachbuilder of choice. Coachwork for most of these cars was completed by H. J. Mulliner & Co. who mainly built them in fastback coupe form. Other coachwork came from Park Ward (London) who built six, later including a drophead coupe version. Franay (Paris) built five, Graber (Wichtrach, Switzerland) built three, one of them later altered by Köng (Basel, Switzerland), and Pininfarina made one. James Young (London) built in 1954 a Sports Saloon for the owner of the company, James Barclay.

After July 1954, the model was fitted with an engine with a larger bore of 94.62 mm (3.7 in), giving a total displacement of 4.9 L (4887 cc/298 in³).{{Citation needed|date=October 2014}}

The rarity of the R Type Continental has made the car valuable to car collectors. In 2015 a 1952 R Type Continental, in unrestored condition, sold for over $1 million USD. {{cite web | url=http://pursuingwo.com/20150502-rare-bentley-r-type-continental-brings-big-dollars-at-auction/ | title=Rare Bentley Brings Big Dollars At Auction | publisher=Pursuing W.O. | access-date=2 May 2015 | archive-url=https://web.archive.org/web/20150518213816/http://pursuingwo.com/20150502-rare-bentley-r-type-continental-brings-big-dollars-at-auction/ | archive-date=18 May 2015 | url-status=dead }}
