Hopefully not as the "Volt". It's a shame the car didn't work out, but the Bolt/Volt naming thing was a source of endless confusion.

The most annoying thing about that naming scheme is that Chevy also makes the Spark, which is 100% gasoline-powered. What was their rationale in greenlighting that name?

The spark was being sold under other names since long before the volt or the Bolt. When they started calling the Spark the Spark the Bolt was still several years off and they certainly didn't have a name for it at that point. The choice of "Spark" coincided with they giving all their small cars a bunch of active sounding names.

The Bolt may have been long off but the Spark name was announced in 2009 and started selling at the same time as the Volt. The Spark was available for the 2011 model year in Europe and for the 2013 model year in the U.S (with a BEV option). The Chevy Volt on the other hand was available for the 2011 model year. So they definitely seemed to be going for electricity themed names.

They offered a Spark BEV from 2013-2016 model years, maybe they intended to offer the battery only option sooner.

Cars have had spark plugs for over one century anyway.

I would rather they upsized it slightly. The Volt is essentially a Cruze body with a different drivetrain, and it is pretty small. I looked at buying one but banging my head on the roof on my way to sit down made me rethink the plan. It doesn't even need to be that much bigger, maybe just taller. A Prius, by comparison, is pretty spacious.

The Gen 1 Volt wasn't just a Cruze body and was a hatchback closer to the "cross-over" territory that is currently all the rage for them. For cost cutting GM moved the Gen 2 Volt into a Cruze body, and then GM killed the Gen 2 Volt for not being a cross-over or hatchback.

Same. Test drove a Volt and it felt like a plastic toy car, meanwhile the Bolt actually has headroom.
