Red Rolls-Royce 20/25 Berline from 1933 with six cylinders, 3690 cc, 90 HP. Max. speed: 120 km/h

The Rolls-Royce 20/25 was the second of Rolls-Royce Ltd’s pre-war entry level models. Built between 1929 and 1936, it was tremendously popular, becoming the most successful selling inter-war Rolls-Royce.

Its success enabled Rolls-Royce to survive the economic difficulties of the Great Depression years and remain one of world’s great brands. A total of 3,827 20/25s were produced, of which over 70% are still on the road today.

The 20/25 was the successor of the highly successful 20 hp Rolls-Royce Twenty introduced in 1922.

The target market for the 20/25 was the same as the Twenty – the luxury, owner driver market. The project to develop the next generation 20 hp was code named Goshawk.

The goal for the new model was to increase power & performance.

This was achieved by increasing the bore size from 3 to 3.25 inches. The stroke was unchanged at 4.5 inches. This resulted in a 17% increase in capacity from 3128 to 3675cc – bring the RAC rating up to 25.4 hp.
