I surely hope they don't discontinue it......I really, really like my 2014, easily my favorite car that I've owned, and even in the 2018 models, now seven years without a major update, it is simply a more practical and even refined car for me than the competition. Same length as the Cruze hatchback, but longer inside from trunk to dash (important for me with skis); more ride height for visibility (useful in urban driving and in general for comfort); way quieter and smoother than other B-class cars (always welcome, why do other manufacturers cheap out on this?); huge trunk with my sedan that allows suitcases to be set vertically (versus the rather shallow affair on the Cruze); and almost ten inches shorter than the Cruze (good for urban maneuverability and parking). Oh, and the fact that GM doesn't shortchange driver legroom like Toyota and Honda and Ford all do.
But the Cruze is a little too large for me, the Spark a little too small, and I might have to consider going to, say, a Subaru Impreza or maybe a Toyota Prius (the one Toyota I've driven with a decent driving position for me) if they were to cut the Sonic. I'd gladly consider a Bolt if they charged faster and I had somewhere to charge it overnight, but neither of those things apply, yet. So give us at least one more Sonic generation to tide us over to EVs, please, or else find a way of shortening the Cruze without crimping interior room so that I can park it in the city.
