While SIA production in Indiana is up slightly from last year it is still down 30% from 2019. SIA produced 368,519 for the 12 months of 2019, but only 275,150 vehicles for the last 12 months. For those same 12 months there were 31,952 Imprezas and 22,180 Legacy US sales.So, which product line in Indiana will Subaru replace with EVs? Impreza or Legacy? My bet is that Impreza will bite the dust: that would cut another hatchback from the American market.
That sounds like a lot of potential factory space to shift EV production to Indiana without initially affecting any existing production lines.
There is some reason to think that a third of the Legacy sales in the US have the 2.4L 260 hp engine, so the Legacy line may be a lot more profitable than the Impreza line even though the total units are less.
I like the Impreza very much, but unfortunately it represents Subaru's past and not its future. In any case the Impreza would not have to be retired immediately, but I have my doubts that it will ever see a 6th generation.
