Also,
@hmp10 , I think that this article answered a lot of questions for us both. First of all;
All Gravities will have air suspension. It looks like the "Zero Gravity" options will be three chamber while the base suspension is one chamber, at least based on this. It also looks as if rear wheel steering will only be available with the tri chamber system.
Smooth mode will have around 500 hp, while the Sprint mode will have the previously mentioned 800+ hp. I assume this is for the DE.
The Gravity Sapphire will be tri-motor, not quad-motor.
It drives well, like an "overgrown Cayenne" or AMG suvs. The view from the interior also seems like what an Air wagon would be like if it existed.
The steering wheel feels appropriate and "proportional" to the vehicle (?? no idea what is meant by this).
Most importantly to me though, sadly, is that the Gravity will have the same toe-room issue as the Air (or, to rephrase it, space under the front seat). The attached picture proves this:
Although I will keep in mind it's a prototype, I doubt that the "hump" (the rise that causes low under-seat space) under the front seats will be changed as the mechanicals should already be
fairly set in stone (assuming they are still on target). I also don't think the Air seat being there instead of the Gravity would make much of a difference, since that upward rise would still be there even if there is space "above" that rise. It would be very uncomfortable to slide your feet in that case, since even if there may be some space above it, that rise would be awkward. Hopefully the Pure/Touring do not have this, as they should have smaller battery packs.
