Ecclestone held BMW to their contract for the 1987 season, but the German company would only supply the laydown engine. The upright units, around which Brabham had designed their new car, were sold for use by the Arrows team. Senior figures at Brabham, including Murray, have admitted that by this stage Ecclestone had lost interest in running the team. The 1987 season was only slightly more successful than the previous year—Patrese and de Cesaris scoring 10 points between them, including two third places at the Belgian Grand Prix and the Mexican Grand Prix. Unable to locate a suitable engine supplier, the team missed the FIA deadline for entry into the 1988 world championship and Ecclestone finally announced the team's withdrawal from Formula One at the Brazilian Grand Prix in April 1988. During the season-ending Australian Grand Prix, Ecclestone announced he had sold MRD to EuroBrun team owner Walter Brun for an unknown price.
