I blew the whole quote which is 3" longer than the Miata overall so you're right with the 90mm claim.
Edit: And 4 person occupancy, that explains it, will be interesting...

A wheelbase of 97.6 inches puts the S-FR about midway between Toyota’s current compact rear-drive sports coupe, the
Scion FR-S (101.2 inches), and the
Mazda Miata (90.9 inches). So, too, does the concept’s overall length of 157 inches, which is 10 inches shorter than the FR-S and three inches longer than the Mazda. At 66.7 inches wide, the Toyota is narrower than both cars, and it’s also taller, at 52 inches.
