but why ? why should they compete,
when most car makers have copied the 4 wheel drive from Landrover
(actually, not even the WW2 JEEP was a new Idea, 4wheel drive was used way back in the 1930`s I think)
all the cars/estates you have shown are just versions, options, rather than new Ideas.
I gave you some more main motor manufacturer 4wheel drive options no one is talking about,
scorpio/sierra.
cavalia/vectra.
and Hi powered cosworths with a sierra body, a scopio body, or a shortend sierra saffire chassis wrapped in fake escort panels as an escort cosworth....
all made, but not in quantities that made it viable.
look at the Japs home market versions of lots of there cars,
lucidis/eminas, and the other mitsibishi people carrier with shogun mechanicles underneath, plus lots of there small cars & light vans not normally sold here in the UK.
I`ve seen odd tiny vans like honda acty 4wheel drive
the only small light truck was the little scooby pickup...
Its all about marketing,
if theres a strong market for a product, people will buy,
if not, they wont, so why make 4wheel drive versions if they dont sell enough..
