I don't know why you aim at them in particular. The only subcompacts left in NA I believe are the Nissan versa and the Mitsubishi mirage, and the Mirage gets killed next year.
They all killed their small cars. All of them.
No more Honda Fit, no more Mazda 2 / Yaris, Kia Rios, Chevy Spark, Chevy Sonic, Nissan Micra, Mitsu Mirage. In Canada at least, the Fiat 500 only exists as an overpriced BEV model with such a small range it's unusable except as a pure city car.
