Creating the Mini Cargo sounds like a simple enough process. Auto Motor und Sport reports that the work-ready hauler will be based on the Clubman, with the rear bench seat removed in favor of a long load floor. The rear side windows will be ditched for sheetmetal (like most panel vans), though it's unclear whether or not the rear windows will be left intact.
We're curious to see what other alterations will be made to the Clubman in its transition to a proper panel van. Will the passenger-side rear-hinged door be left alone, or will it be removed? Will the rear suspension be strengthened to accommodate for heavy hauling? Assuming that plans for a Mini Cargo are indeed underway, we'll have to wait until March to find out.
