Rolls Royce 20/25 hp (USA built 1929 - 1936)


one of the few good looking cars of this model
1935,Gurney Nutting Sports Saloon

Keeping up with Rolls-Royce's two model policy the R-R 20/25 hp was built as a stablemate to the big R-R Phantom II. In comparison to the previous 20hp model, the 20/25 hp offered better acceleration and higher top speed. A better overall average fuel consumption than the predecessor's was an added bonus. The increased power output did give coachbuilders greater opportunities to build larger bodies. Nearly 4,000 chassis were produced and make this Rolls-Royce's bestselling model of the period between the Great War and WWII. 3827 Rolls-Royce 20/25 H.P were built.
