BL finally pulled out of the project in 1983. Perkins initially decided to pursue the project alone, and even produced advertising brochures for the engine as an industrial power unit, but BL withdrew all technical support and Project Iceberg was wrapped up in late 1983. BL's other collaboration with Perkins (producing a diesel version of the O-Series engine) produced the highly successful 'Prima' unit. BL (and its Rover Group successor) bought in 2.5-litre 4-cylinder turbodiesel units from VM Motori to use in the SD1 and Range Rover.
