I'm not trying to make a serious suggestion, but more like a thought experiment. What about stacking two Tesla’s batteries on top of each other? Of course you would need to remove that hump in front. But if you remove that hump and stack e.g. two new 100 kWh packs together (minus hump), you could get something like (WAG) 180 kWh capacity. Of course that would weight so much that you could not use it in sedan. But perhaps in big pick up or full size SUV. At the moment batteries limit the available HP's but with this you could use Tesla's bigger motors in front and rear and get something like 840 HP's. What do you think, would there be market for that? Or would price be too high? Of course in practise Tesla does not have the resources to do this at the moment.
