1. Bolt looks like a small hatchback. Looks normal to me.
2. Bolt is a ground-up new design for GM. It's not a modified ICE.

3. GM's battery sourcing has no problems currently, nor in the foreseeable future. Many companies are ramping production to provide low-cost cells (inc. LG Chem, Samsung SDI, BYD).
4. You'll hear more from GM and others about DC fast-charging in the coming year or two. But this is definitely one of the big achilles heels for the Bolt, until DC fast chargers are more prevalent.
IMO:
I hated how the LEAF drove... I didn't take it seriously and still don't.
I was impressed at how the Volt drove, and I think it was a noble attempt at a plug-in hybrid.
The Bolt... I'm going to wait until test driving it to make a conclusion. But it's definitely in a different (smaller, less performance) class than the Model 3... and ultimately the price will need to reflect that.
