"I much prefer smaller sports car," Nakamura tells the Herald. "It is the time to look at that. With 370Z, we still don't know next generation will have a larger or smaller engine."
If Nissan were to reduce the size of the 370's powerplant, it would be the first time that model's displacement has dropped. Since the Z gets its model designation from the size of its engine (3.7 liter V6), Nissan could have a problem marketing a smaller Z called the 300Z, since the last time a new 300Z was sold in the States was way back in 1986.
More likely would be the revival of long-forgotten nameplates like 200SX or 240SX. Either would almost certainly be direct competition for the Subaru and Scion rear-drive coupes.
Nakamura reminded fans that even if the 370Z loses some cubic inches, Nissan will still have the young but already legendary GT-R. When asked if Nissan would be willing to support three sports cars, Nakamura says, "If there is a market, we will do it."
