"Most" as in the direct competition to the Model X. Yes, some manufacturers have large 8 seaters (Yukon, QX56, Pilot, Sequoia) but those are all massive vehicles and I don't think the Model X is competing with those. I think the competition is the smaller SUVs such as the Q7, SRX, MDX,GX, X5, GL550, and XC90, all of which are 7 seaters.
