China is going to be the largest car market in the world soon.
I would let others try out the first batch but I think a made-in-China Cummins should not be discounted immediately just because of location of manufacture. China makes millions of cars today and while they are not as well-made as Japanese cars, the quality is getting better fast. If the Cummins warranty is good, that's what matters, no?
I think the 2.8 is a tad small for any 60 or 80 Wagon if it is going to be lifted and carrying a heavy load. Would be fine in a Shorty Cruiser.
Toyota has put the 2.8 4-cyl 1GD-FTV in the Prado- but I wonder how many choose this option over the petrol/gas version.
The premium for diesel in the Prado is 700K JPY or around $6500 USD. Would you pay that much more for a diesel in your Prado? I probably would because the petrol option is the 2.7L 2TR-FE, which is down on torque by a lot compared to the 1GD.
The 1GD numbers are very similar to the Cummins 2.8 both in HP and torque.
The VDJ is too dirty for Japan's emissions, sadly.
