The Quant looks like an amazing vehicle that has a 600km range and insane sub 3 second 4wd acceleration. A couple of things to keep in mind though:
1. If you have $1M to spend you could build a pretty big/fast Nissan Leaf or Tesla Model S.
2. Not much has been said about the nanoFlowCell and it is hard to gauge exactly how much storage it can produce
3. I hope my pessimism is wrong and they build lots of these.
