The T6 Ranger, as it is now, will never be sold in the United States.
When it was launched, it was simply too big. Too close to the F150.
And now the Ranger's natural competition, the Colorado, has been released in the US.
But the US Colorado is nothing like the global car. It's much bigger... and bigger than the Ranger, which was already "too big".
In other words... if Ford wants to sell the Ranger, they'll have to upsize it... which will lead to the market cannibalization they were trying to avoid in the first place. They could downsize it, but the rest of the world is already enjoying the new, bigger Ranger, and wouldn't buy a smaller one... so your economies of scale go out the window and you've got a new, small truck only sold in the US that has to meet strict Federal standards... which will cost $$$.
So... no Rangers for you. Sorry.
