In the market, it will surely be close to a suburban. I am still in shock by the air and how it was even possible to fit that much space, considering I am used to gasoline cars and their builds.
In addition, a large frunk(almost guranteed to be 18-25 cubic feet) will remove the need for a large rear cargo area, which will mean the third row seats can be pushed further back without compromising anything. If my memory of the Air launch serves me right, I will likely spend the next month trying to sketch out how the fuck they managed to do that amount of interior space on a piece of paper every week, and failing every time.
