In 1988 Ecclestone sold Motor Racing Developments to Alfa Romeo. The Formula One team did not compete that year, but Alfa Romeo put the company to use designing and building a prototype "Procar"—a racing car with the silhouette of a large saloon (the Alfa Romeo 164) covering a composite racing car chassis and mid-mounted race engine. This was intended for a racing series for major manufacturers to support Formula One Grands Prix, and was designated the Brabham BT57.
