I'm in the process of getting a new chair. I found one that is made out of magnesium. The complete chair, less cushion and rear wheels weighs less than a gallon of milk. Check out the BT-Mg.

Overall, the chair isn't that large but it is awkward based on it's dimensions. The back rest is about 12" high. In total, without the rear wheels on, it is 18" wide. Measurement B is about 18", C is 22", D is irrelevant. E is 18". The front down tube angle is 85* (IIRC). With the rear wheels off it becomes an L shape but it all depends on the shape of the interior. Hope this measurements help. I just don't have the ability to get out to California to see these vehicles. I'm going to need to see a model 3 soon as I am an early reservation holder.
I figured the roof would have to stay home of possibly directly behind the front seats. I'd have to get a look in there to see. This is also a very large concern for me as I''d like to get the wife a model 3 but only if I can
put my chair in the trunk.
Do the engineers ever come chat with us for things like this? That would be outstanding. Hope this stuff helps.

I used to use a road racing chair similiar to this but they are too uncomfortable for me. I prefer to race in a hand cycle. Much more comfortable. But ultimately, my sport is rowing. It is what I excel at. The first is a hand cycle. The sleaker leaner one is a push rim racer. Both can be very fast.
