Another option to the utility route is that they go the G-Wagen way.
They have positioned themselves as a luxury brand, dropping the freelander and so on - so similarly positioned in the market to Mercedes perhaps.
At the end of the Defenders life they were at least partially positioning it as the niche 'real / rugged / leather seated 4x4'. They won't be ignorant of the Khan, Urban Truck, Bowler type mods going on at huge prices. So also not unlike the G-Wagen's market position.
They seem to be happy to do to low volume hi profit models - the series 1 restorations, the aluminium e-types, the re-invented special vehicles ....
So maybe we'll see a mega defender, with top spec powerful engine, clever electronics, on a strong beam axled chassis, with a luxurious interior, limited numbers, waiting lists, and huge prices ?
Sold as 'the icon' and priced accordingly?
