History of the Rolls Royce 25/30
The Rolls-Royce 25/30, produced between 1936 and 1938, is an improved version of the 20/25 with a bigger engine to offer more power, as over-large bodies were frequently attached to previous models, resulting in complaints about its performance. The in-line six-cylinder overhead valve engine is identical to that used in the 20/25 but has a larger capacity of 4257 cc. The Rolls-Royce carburettor was replaced by a single Stromberg downdraught carburettor, and magneto ignition was no longer used, however, a backup coil was provided. Third and top gears were outfitted with synchromesh.
The inflexible front and rear axles were still supported by half elliptic springs with hydraulic dampers. A mechanical servo assists with braking on all four wheels. For the handbrake, separate rear brakes are installed. Rolls-Royce only produced the chassis and mechanical elements. The body was constructed and installed by a coachbuilder chosen by the owner.
