Costs are somewhat protected right now, but it was less than 75k. And since it's a prototype and not a full company, yes, there really is no warranty (unlike the motorbike project, where there is).
Range is also a negotiable thing, to a point - this doesn't get as much as the Tesla (yet?) but it doesn't need to. He can commute to and from work, and then some, and charge up. Considering charge times take in the minutes with the right setup, that's plenty. It's a pretty small group of people that are driving more than 200 miles everyday without stopping for a charge.
The other nice thing is that since we already have the gas station infrastructure in place, it can be converted to charging stations. With the right setup, you can charge this kind of car in mere minutes (think 15 minutes). All this means is that while the 200 mile range is nice, it's unneeded and a waste of money.
