FYI: (This is a follow-up article.)
On Monday Mary Barra, GM's CEO, announced the company was going to improve its cash flow by $6bn/year by the end of 2020. It's going to do this by laying off 15 per cent of its workforce. There's some other stuff in the announcement, but none of it contradicts the basic story: GM makes too many different products, and thinks it can do better for its shareholders by making fewer of them.
