The Iceberg engine was slated for fitment in the Range Rover, Rover SD1 and the Jaguar XJ but the project encountered problems with failure of the alloy cylinder heads and internal cooling. They were limited by the need to use the same basic block casting as the petrol engine to allow the Iceberg engine to be produced on the same production line to reduce costs. Whilst these problems could have been overcome, the project ran into financial and logistical problems caused by the reorganisation of BL and specifically the splitting of Land Rover and Rover into separate divisions.
