20/25 H.P., 1933, #GTZ67, Hooper Limousine. The vast majority of 20/25hp
were bodied with spacious limousine coachwork similiar to this.
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..
