Nissan redesigned its rear-drive sports car for introduction in spring 1989, adding a turbocharged model that fall. Two curvaceous body styles were offered: a 2-passenger coupe, and a 2+2 coupe with a small back seat. A 222-horsepower, 3.0-liter V-6 was standard in all models except the 300ZX Turbo, which came only in 2-seater form. Equipped with twin turbochargers and twin intercoolers (one set for each cylinder bank), the four-cam, 24-valve 3.0-liter engine developed 300 horsepower with 5-speed manual shift, or 280 horsepower when fitted with a 4-speed automatic transmission. Automatic also was available with the less-powerful engine. Turbos had intercooler inlets in the front air dam, a rear spoiler, Z-rated tires, and super HICAS (High Capacity Actively Controlled Steering) 4-wheel steering. That meant the rear wheels first turned slightly in the opposite direction from the front wheels, then in the same direction, to improve stability in fast lane-changes. Antilock braking was standard. Door-mounted front seatbelts could be left buckled, to deploy automatically. A T-top roof was standard on the Turbo model. Other 2-passenger coupes could have a fixed roof or the removable roof panels.
