quoted from an interview between autoguide and Nissan VP of Product Planning, Pierre Loing:
Previous to that, Loing was less than open on the brand’s plans for its next-generation of sports cars, though he did provide some hints at the future. He described the two opposing sports car formulas, the first of being a car with a big engine and equally big horsepower ratings. This concept he referred to as “US centric,” commenting that such a car, “becomes almost unsellable in Europe and China because of CO2.” He even admitted that the appeal of such cars is dwindling in the US saying that, “it still sells in the US, but not in as big of numbers as it used to in the early 2000s.”
Commenting that the big horsepower, big engine philosophy is, “the current recipe of Z,” the alternative is a smaller vehicle with a lower displacement engine utilizing turbocharging. “We are still studying between those two,” said Loing, though it would appear the decision for the latter has already been made.
