This is awesome, except for one thing. As with all hybrid kits, you lose trunk space. Unfortunately, if I can't fit my groceries as well as the stroller for my daughter, it's out of the question. Obviously not everyone requires this, but how many commuters do you think never need the trunk space?
These batteries and controllers need to find another place. On the roof of the car, perhaps, unless you're an outdoor sports person and need racks for bikes or a kayak?
They don't show any photos, but I wouldn't be surprised if the batteries don't occupy the entire trunk, especially on the production model. Obviously this would also be dependent on the size of the original vehicle as well.
He mentioned the prototype is larger than it needs to be. They needed to have easy access to data ports to pull diagnostics info from the batteries and controllers.
The size of the final version should be about the size of a carry-on bag.
The video mentions that the production ready kit will be about the size of an airplane carry-on bag. I think for most cars it's possible to fit a roller carry-on bag, a stroller, and groceries with ample room leftover.
