It did not work the first time Ford offered the Ford Ranger in the US. Low sales number had lead to Ford removing the truck from their US lineup so what makes them think that it will work this time?
To be fair, the truck segment in one of the most popular segment in the US right now so offering a truck does make sense but will people want the Ford Ranger. While the truck was removed from the US market, it continued to strive is markets like Australia.
Rumors about Ford thinking about offering a truck start a long time ago but rumors about it being the Ford Ranger started after the truck was spotted getting tested here in the US.
While Ford has not announced anything yet, it is currently believed that the Ford Ranger will be produced at their Michigan plant in 2017 after the Ford Focus and Ford C-Max contract ends.
