The BOLT is NOT a clean sheet
The BOLT is NOT a clean sheet BEV design. It is a mish mash combination of parts from other GM models, parts that were not specifically designed for a BEV yet were adapted to the BOLT. These are not million mile cars like Tesla models.
The biggest reason they are not selling is that they look like a fancy tennis shoe. Just plain ugly. A BEV car from GM should have been an original BEV design based on a medium sized sedan with 4 doors and possibly a brief hatchback. This is what the public wants, ala Tesla Model 3.
