20-ish mile range difference between 5 seat and 7 seat Gravity?

If you can find a selection of summer performance tire sets that will fit the 22/23" wheels, I'd certainly like to know about it. As I said, the Michelin Pilot Sport 4S will fit if you are okay with different speed ratings and an EV/nonEV tire split between the axles.

I'm not being sarcastic. I really would like to get comfortable that tires won't be exceptionally tricky to find for those wheels.
I did have to manually plug in the sizes, but it looks like Aston Martin spec summer Pirelli PZero PZ4 summers? It's a little sketch, they may be similar to DBX tires, but the load rating may not be sufficient, we don't know the Gravity curb weight, although I have optimism that it might actually just be under 6000 lbs (Touring being 400 lbs less than GT). Otherwise putting summers on the 21/22 would be significantly easier since JLR seems to use them on performance SUVs. It's like mutant of Land Rover fronts and Aston Martin Fronts. Seems too early to speculate and find this stuff. Only thing I can see is that the 22/23 are going to be seriously expensive replacement rubber relative to standard Hankook EV stuff....
 
Pure speculation here, but I'm guessing it's some kind of rack and pinion device driven by a motor placed between the floorboard and the bottom of the seat cushion. It wouldn't require a large motor, and there should be room for it there.

A better picture of the mechanism in this photo from reddit: https://www.reddit.com/media?url=ht...bp&s=92b7d46b4b47b487f57c52ff703a0de94355fe5d

That looks like a fairly deep mechanism, requiring at least an inch of floor space, maybe 2?
