I did wonder when this Q? would arise. A friend and I were discussing exactly the same a few weeks ago. We came to the conclusion that unless LR produce a "military grade only" version LR have no chance of selling into the MOD as the new Defender is simply too complex; and no other military organisation will buy a combat vehicle that can only work when all 85 ecu's are fully functioning.
This led to the Q? If LR/TATA Group still see a significant global market within international defence they will need to offer a C21st combat ready vehicle...and this may not be the new Defender as we know it. If still a Defender, albeit a properly stripped out/down and armoured up version, could this lead to a lower cost Defender? Maybe even a Defender with wind down windows, no ECU's and no ridiculous over priced accessories list? If the answer is yes, then we could see a new Defender without the fluffy guff added to the current offering. If the answer is no, this leaves a market wide open for competitors to walk into, doors wide open. Which means Jim 'Grenadier' Ratcliffe's £600M investment could be a very smart investment. I for one can not wait to view the Grenadier...
