Subaru has said that the costs assosciated with a low-priced mini car (Fit, Yaris, Fiesta) doesn't make financial sense. They don't intend to sell one.
Subaru knows how to sell only what is necessary and that showed through in the economic down turn when they made a profit as everyone else walloed in excess inventory. And, with gas prices under $4, SUV sales are up and mini-cars down, so Subaru was right.
