Remember, the FJ Cruiser was intended to evoke the memory of Toyota's famed FJ Land Cruiser series, which were (and still are) legendary for their off-road prowess and durability. The FJ had some legitimate off-road chops, too, but don't expect the same kind of mission statement from the TJ Cruiser, if it ever does hit the showroom floor. The FT-4X was marketed toward Millennials – which didn't sit well with some of us – and the TJ Cruiser would likely go down a similar path as a small, utilitarian crossover.
When the TJ Cruiser will actually hit the market is unclear, but since it will likely ride atop Toyota's TNGA C-Platform, which also forms the basis of the C-HR, a solid chunk of the development work should already be done. All we can do now is wait and see.
