From the Rolls-Royce factory in Derby the second model to bear the Bentley label was the Bentley 4 1/4 Litre. For an extra £ 50 a 4 1/4 litre engine was offered from March 1936 as an option in the already well-received Bentley 3 1/2 Litre chassis. Within short period sales of the 3 1/2 Litre declined and in fact the Bentley 4 1/4 Litre had become its substitute. The MR and MX chassis series introduced in 1939 were the final development of this model. Features like over-drive top gear as standard and improved White Metal bearings made the car ideal, then and now, for unstressed long distance Continental touring.
