Ok, for those of you who are impatient, you can take a look at these two images. This is the actual body that will be in the final production, except for some minor changes that may be decided in time to come.
This is the stage as of March 2008. As you can see it is not complete yet, the grille is not fixed, while the interior is basically blank.
The engine will not be a Campro since 1600cc would be ridiculous for a vehicle this size. All the rumours on superchargers are not true. Currently a 1800cc Mitsubishi sits in the engine bay, mated to a CVT transmission, and is in the "testing" stage.
The plan is to have 2 major variants. A regular and luxury. The luxury will have a 2000cc engine (not V6), Traction Control, keyless entry, 2nd row armrests, leather seats all round, and other amenities. Sun roof was planned but later scrapped after some market survey.
Both variants will receive Vehicle Information Display (PROVID), 2nd row air-conditioning, and all round power windows
Size is larger than that of Stream and Wish, but not the Grandis.
Dimensions:
Wheelbase - 2780mm
Length - 4580mm
Width - 1760mm
Height - 1540mm
That's it for now, more updates in time to come.
