The production of the Rolls-Royce Wraith was carried out from 1938 and 1939 at their Derby factory. It took over the Rolls –Royce 25/30. The Wraith had a wheelbase which was four inches larger than its earlier model. The overhead valve and the 4257cc engine were also based on the 25/30. The car had a cross-flow cylinder head and a four speed gearbox. Other than the first speed, the higher ones had synchromesh and was a right hand change going by the tradition.
