They dropped the Volt which you can only pry out of owners cold, dead hands. They dropped the Bolt EUV which seems to be similarly adored.
What dumbass metric is causing these stupid decisions?
Sales and margin for the most part. The sales part, I imagine it's largely a failure of successfully marketing the vehicles, but I could be wrong.
The Volt to me was largely a failure of marketing at the time. Practically no normal people I know have any clue about what the Volt was. I went to a few dealerships to look at one and most salespeople didn't have a clue about the car (common though with car sales) or didn't even have any on hand to show. There was practically zero mindshare of GM equating with hybrids; the vast majority of car buyers I knew interested in hybrids essentially only knew/cared about Toyota. With declining sedan popularity in the US the writing was on the wall.
The Bolt was seen by many US car buyers as too small of a car and often confused for the several years older PHEV Volt. The amount of normal people I've heard use Volt/Bolt interchangeably is incredibly high. The people I talked to about the Bolt EUV figured it was just a different trim level of the same car, not realizing it was a good bit bigger.
Three different cars with different capabilities and yet so many people would just think they're the same V/Bolt thing GM talked about a decade or so ago.
