The Rolls-Royce 25/30 built between 1936 and 1938 is an updated version of the 20/25 with larger engine to provide more power, as often, over-large bodies had been fitted to the earlier model leading to complaints about its performance.cite book |last=Sedgwick |first=M.|title=A-Z of Cars of the 1930s|year=1989 |publisher=Bay View Books |location=Devon, UK |id=ISBN 1-870979-38-9]

The in-line 6 cylinder, overhead valve, engine is similar to that used in the 20/25 but increased in capacity to 4257 cc by increasing the bore from convert|3.25|in|mm|1 to convert|3.5|in|mm|1 with the stroke remaining at convert|4.5|in|mm|1. The compression ratio is 6:1. A single proprietary Stromberg downdraught carburettor replaced the Rolls-Royce one and magneto ignition was no longer fitted but a standby coil was provided. The four speed gearbox is mounted in unit with the engine and a traditional right hand change used. Synchromesh is fitted to third and top gears.

The riveted chassis has rigid front and rear axles suspended by half elliptic springs with hydraulic dampers. Braking is on all four wheels assisted by a mechanical servo, famously under licence of Hispano-Suiza. Separate rear brakes are fitted for the handbrake. The traditional Rolls-Royce radiator with triangular top was used with vertical louvres, the angle of which is controlled thermostatically to control engine cooling.

Only the chassis and mechanical parts were made by Rolls-Royce. The body was made and fitted by a coachbuilder selected by the owner.
