The new Rolls-Royce 25/30 hp launched in the Spring of 1936 was at first offered as a model to be built alongside the 20/25 hp. It found a ready market with those who appreciated the prestige of the marque and engineering at top quality level but perhaps did not need the superior performance of the Phantom models. An evolution of the well-proven 20/25 hp engine the capacity had been increased from 3,669 cc to 4,257 cc. Improved performance enabled a top speed of about 75-80 mph depending on the type of coachwork fitted. The 25/30 hp in chassis form retailed for just £50 more than its predecessor.
