"Jeep has also announced that a 3.0L EcoDiesel V6 turbodiesel engine will become available on the Wrangler and Wrangler Unlimited in Europe beginning in 2019. it will produce approximately 260 hp (194 kW; 264 PS) and 442 lb⋅ft (599 N⋅m). This is for the Europe market. The rest of the world except for North America will get a 2.2l 4 cylinder turbo diesel. North America will not get a diesel Wrangler right now, even though the 3.0 EcoDiesel is used in the North American Ram 1500 and Jeep Grand Cherokee" from

I do wonder if this is correct due to the fact that many countries in Europe have Heavy taxes on big diesels and they are trying to bann them in the cities, maybe the smaller 2.2 diesel, but what do I know.
Here in Sweden the annual road tax for the pentastar is about 500 dollars and the current diesel is maybe 900 dollars, almost twize the cost and a new 3 liters V6 is bigger and will probably cost even more in taxes.
