Two small independantly mounted engine/transmission units are not a good substitute for a single engine with a 2 speed transfercase on steep climbs, because the low powered rear engine which due to weight transfer will have to pull a lot of the vehicles weight will tend to stall, whilst the front engine will just uselessly spin the much more lightly laden front wheels.
After test results proved unsatisfactory, BMC developed the single engine dual range Austin Ant using many Mini/1100 components, but the British armed forces purchased Land Rover lightweights instead
