Background
Even before the Armistice in 1918 Henry Rolls had predicted the need for a new, “small” Rolls-Royce. He had postulated that a significant number of Rolls-Royce owners would find themselves unable to recruit or afford the number of staff they had enjoyed the luxury of before the War. He sensibly assumed that a smaller less demanding car than the Silver Ghost would attract a following, especially if it no longer necessitated retaining the services of a chauffeur.
With the new car given the go-ahead by the Rolls-Royce board in 1920, the company were keen to reassure the public that it may be a more accessible model but that “under no circumstances would the standards of excellence maintained in their products be diminished.” On 6 October 1922, Rolls-Royce unveiled its new ‘small horsepower’ car. Its six cylinder, 3.1-litre engine was less than half the size of the Silver Ghost's engine, but the new model also weighed around 30% less than its larger sibling rendering the performance differential impressively narrow. The car was simply called the “20 h.p.” thanks to its output under the RAC taxable horsepower rating. The car soon simply became known as the “Twenty.” The Rolls-Royce was very well received by existing customers and new converts alike. One owner wrote to the company stating that “‘I drove my 20 H.P. here (France) from Liverpool and am very satisfied with the running of the engine, not having to change gear between Liverpool and Versailles.”
This was a time, of course, when Rolls-Royce would supply just the chassis and running gear leaving customers to appoint a coachbuilder of their own choosing. A number of long-established and experienced coachbuilders existed who could create a majestic body to go with your Rolls-Royce chassis, one of the most prolific of which was Barker. Barker had been founded in 1710, making carriages for the well-to-do. By the 1920’s, however, the demand for sturdier bodies resulted in Barker using heavier components rather than embracing developments in the use of light alloys. As such Barker bodies were considered as amongst the heavier offerings ultimately leading to them being acquired by their key competitor, Hooper, in 1938.
By the time production had ceased in 1929, 2,940 examples had been built and sold. The Twenty was a highly influential model and the straight‑six-cylinder engine – with detachable cylinder head and overhead valves – becoming a template for Rolls-Royce engines for the next 30 years.
