STROM 2

However more strength EU3 emission regulation prompted Land Rover engineers to hone the injection and exhaust system even further. The cylinder head was reworked, injector pressure was upped from 1350 to 1750 bar, and a cooler was fitted to the Exhaust Gas Recirculation (EGR) system to further reduce nitrous oxide emissions. This new Strom 2 finally needed a catalytic convertor to comply with emissions legislation.  

They put on a very lightly loaded cat with a very small amount of precious metal, which made it cost effective, because they don’t have very much to clean up. But without it, legislation was just too tight to know that every engine would go down the production line without a problem.

Little was said publicly about the revised engine; after all, this was largely complying with legal requirements. Performance was little changed, though low throttle take off control was improved.
