Interior volume numbers are captured all kinds of ways and not always consistently. Most sources give the Odyssey interior volume as 163.5 or 163.6 cubic feet in one trim and 160.1 in another trim. Lucid gives the Gravity cargo space as 112 cubic feet, but I have found no number for total interior volume. (Remember that the Lucid cargo space number includes the frunk.) So an apples-to-apples comparison of Lucid volume to Odyssey volume is hard to do.
We have been driving a Honda Odyssey since 2011 and now have a 2018 Odyssey. And I have spent a good part of an afternoon sitting in and playing around with the interior of a Gravity. Here's the bottom line of my own observations:
The passenger space of the Gravity looks and feels roomier than the Odyssey. The third row of the Odyssey is a bit easier for ingress and egress, but the Gravity third row is just as roomy with the second row in both vehicles pushed all the way back. In the second row, the Gravity seating really outshines the Odyssey, with longer bottom seat cushions and considerably more legroom with the front driver seat put to my preferred driving position in both vehicles. And the front seats of the Gravity outclass the Odyssey in legroom, perceived width, and seat comfort and adjustability.
In short, there will be nothing that we have done and carried in our Odyssey that we will be giving up when we switch to the Gravity. And we'll be picking up sports car power and handling, all-wheel drive, and a host of comfort and convenience features.
Dude. It's a Schrödinger’s cat paradox. Full stop.
A Lucid Gravity is in superposition until you observe it.
And when finally do, you'll see that it's an SUV.
The proportions are because it is low relative to other 3 row and large SUVs, it is 65in height as listed on the Spec, which is the same height as my 14 Honda CR-V, but it is 20 inches longer.
If this is a minivan, it's the sleekest and coolest-looking minivan I've ever seen:
Having seen this one twice in the flesh and an Aurora Green one, too, I can attest to what @Knucklehead and @msaunders9430 posted: some photographs are very misleading with this vehicle. It looks much racier in person than any minivan I've ever seen.
