The Isis was a revised version of the 1927 Morris Six (JA series) and used the same 2468 cc engine and 3-speed gearbox. It had an all-new chassis, and the steel body had an American look, not surprising, as the body pressing dies from Budd were shared with some Dodge models William Morris had recognised the potential of pressed steel car bodies and introduced them to Europe in Pressed Steel Company, a joint venture with Budd, sited beside William Morris's plant.
It was the first Morris to have hydraulic brakes and chromium plating replaced the previous nickel finish on brightwork.
The car could exceed 65 mph (105 km/h) and return 28 miles per imperial gallon (10 L/100 km; 23 mpg-US).
After 3939 of the original Isis model had been made it received a facelift in 1932. Following the court-forced separation of William Morris from his joint venture with Edward G Budd the steel panel body was replaced by a traditional wood frame construction. Mechanically the car was similar but the gearbox received a fourth speed. The chassis received additional cross bracing in 1934 and an automatic clutch and freewheel were fitted to some models. 3467 of the new Isis were made (including Twenty-Five models).
A de-luxe version, the Morris Twenty-Five was launched 12 October 1932 for the 1932 London Motor Show with larger 3485 cc engine. It was replaced in July 1935 by a new Twenty-Five, the flagship of the series II Morris range, and given an overhead valve engine (as the series III) in August 1938 with the rest of the Morris range.
