That test is 60% city. On the highway at 75 mph, the Bolt would likely drop to 200 or a little below. The Model Y LR AWD does ~240 under similar conditions.
Yep - Augusta to Atlanta (Lithonia Supercharger) is also brutal going 75mph and up 400ft in elevation, and there's no supercharger in between the two cities. A 3 SR+ RWD will average maybe 150 miles of range along that route.
Yeah, that'd be cutting it pretty close. I'd be tempted to bring a CHAdeMO in case it looked risky mid-route. I bet there's at least one CHAdeMO along the route.
