no ER fuel engine
If I can't go morwe than 90 miles without having to take at LEAST 30 minutes to fill up (they did not mention the use of SCiB batteries or Li-Tit, so it;s LiPo at best, and that means long charges), and that's assuming availability of a 3 phase charging station, it's not an option. I don't knowe too many people who do more than 45 miles each way to work, but that does not account for trips to the store, days shopping around town and running errands, bringing the kids to sporting events, and more. 90 miles is NOT enough, even for folks who commute less than 30 miles a day round trip.
Put a 2-3 cylender ICE in it that can generate at least 2/3rds of the cars battery draw with a high efficicny generator. What can that really add, $1500 to the car's cost? The battery then can be smaller, getting maybe 60-70 mile range, and shaving 20% of the packs, likely saving the same $1500. If I can go 250+ miles in it, then i don't have to have a SECOND car. On the rare occasins I'd use fuel (average likely 10 miles a day) even if the extra $1500 and saccrifice of a few cubic feet of cargo space was the result, that's less than the costs to own a second car, deal with having to swap cars, and keep in mind, the cost estimates to fill the battery up are based on home power; don;t think for a SECOND using a fast charger will cost the same, it will likely be double, close to the same cost as gas to drive the same distance.
