Rolls-Royce 20/25 and the small-horsepower cars: grandeur for the merely wealthy (1922–1939)

Not every Rolls-Royce customer employed a chauffeur, and Henry Royce built for the rest: the 20hp of 1922 began the small-horsepower line that brought the best car in the world to the doctor, the solicitor and the squire, growing through the Rolls Royce 20/25, the pre-war company’s best seller, to the 25/30 of 1936. The small cars carried the same engineering religion at two-thirds the money, and they remain the gentlest door into pre-war Rolls-Royce ownership today.

The 20hp: Royce goes compact

The post-war market wanted a Rolls-Royce its owner could drive, and the 1922 20hp answered: a 3.1-litre overhead- valve six in a compact chassis, unhurried by design and utterly refined by religion, priced well under the 40/50 flagships. Purists grumbled at three speeds and a central change, soon corrected to four and the right hand, and 2,940 were built to 1929 wearing everything from doctors coupes to little limousines. The formula, full Rolls-Royce quality at approachable scale, never changed thereafter.

The 20/25: the pre-war best seller

Enlarged to 3.7 litres in 1929, the 20/25 became the company’s inter-war workhorse: 3,827 cars through 1936, more than any pre-war model, serving exactly the clientele Royce imagined and quite a few chauffeurs besides. Pace rose as coachwork fattened, synchromesh and refinements arrived year by year, and the registers today document a survivor population of remarkable depth. The 25/30 of 1936 completed the growth at 4.3 litres, sharing its enlarged six with the sporting sister marque’s cars from the same works, before the Wraith modernised the line in 1938, and together the family defines sensible pre-war grandeur.

Every coachbuilder, every body

The small chassis democratised the coachbuilt age: Park Ward, Hooper, Thrupp & Maberly and the great houses dressed thousands, while provincial builders like Caffyns of Eastbourne served their counties, producing saloons, sedancas, tourers, dropheads and the beloved doctors coupes. No catalogue existed; every car was an order. That variety is the family’s collecting joy today, and its market logic: the body sets the price, from accessible formal saloons to the open coachwork that leads every auction, with the Phantoms’ economics repeated at friendlier numbers.

What a small-horsepower Rolls is like to drive

The small cars drive as their buyers hoped: the sixes pull with silken, unhurried elasticity, the controls reward period technique without demanding heroics, and the chassis rides with the house composure at a scale that suits modern roads far better than the flagships. Sixty is a contented cruise, seventy possible late in the family, and the owner-driver brief shows in every control weight. The pre-war touring scene runs on these cars, and a well-sorted 20/25 will cross a country in a day with ceremony intact.

Buying into the family today

Coachwork rules: ash-framed bodies want expert structural assessment, restoration outruns values, and sound original cars are therefore the only sensible buys, verified against the registers that know most survivors. Mechanical parts and knowledge flow through outstanding clubs, the 20 Ghost Club and the marque’s technical network serving the family devotedly. Closed cars offer extraordinary engineering per pound; tourers and dropheads carry the premiums; doctors coupes charm everyone. Buy body, history and registers’ verdict together, exactly as with the family’s larger siblings.

Running one today

Ownership is more approachable than the radiator suggests: the small sixes are willing, patient engines that thrive on regular use and careful lubrication, most consumable parts can be had or made through the marque network, and the technical literature is deep enough that a competent home mechanic can handle routine care. Thirst in the low teens and stately gearing set the touring rhythm rather than limit it, and insurance and storage, not mechanical attrition, are the real budget lines. The wedding-trade past that once dented the family’s image has faded into its opposite: survivors that worked for their living tend to come with continuous histories, and the clubs’ events give the family the active social calendar that keeps values honest and cars exercised. A 20/25 used monthly is a happier machine than one embalmed, and the market has learned to pay accordingly.

Where the small Rolls sits in the market

This is the accessible pre-war Rolls market. For hand-built Derby engineering wearing bespoke coachwork, the closed cars in particular remain among the great value positions in the entire pre-war world, and the family’s club support makes the ownership as approachable as the price. The full record, 524 recorded sales with the earliest 20hp the dearest of the three and a famous coachbuilder often lowering rather than raising the figure, is on the page covering what a 20/25 sells for. Buyers who choose on structure and history rather than gloss consistently do best here, exactly as they do across every corner of the coachbuilt pre-war world built on the same Derby engineering.
