also had dual mirrors, air conditioning, tachometer, and power door locks and windows in some markets and possibly electronic fuel injection. The B12 chassis would be the last chassis to offer a station wagon model. Even more rare are the four-wheel drive versions of the station wagon, offered as an option for the 1987 (late introduction), 1988, and 1989 model years. These models featured an electrically activated single-range transfer case to drive the independently suspended rear wheels, making the car a selectable four-wheel-drive (not all-wheel-drive) vehicle. Sales were mediocre, totalling 429 in calendar year 1986, 2,050 in 1987, 2,408 in 1988, and a final 892 deliveries in 1989. All 1987 Sentras came standard with the E16 engine with , excepting the Sport Coupé and the later four-wheel-drive wagon, which received the throttle-body-injected E16i engine with identical power output. A five-speed manual transmission was standard, with a three-speed automatic available as an option. In 1988, all Sentras had the E16i, which was offered for this year with throttle body injection (TBI). In many parts of the world the E-series soldiered on in the B12 chassis with some versions getting the multi-point fuel injection E16E engine. From 1989 to 1990, the only engine choice was the GA16i, a 12-valve SOHC predecessor of the GA16DE. Transaxles offered were the 4- and 5-speed manuals (RN4F31A and RS5F31A, respectively) and a 3-speed automatic with torque converter lockup (RL3F01A). 1989 saw a subtle change in the body style of the Sentra sedan, as new larger, more rounded front corner lights were introduced to the front fenders and redesigned taillights were added to the rear fascia (station wagon retained same rear lights). The Nissan logo on the front grille was relocated from the right hand side to the center. In 1990, electrically retracted front shoulder belts were added (for the US market only), as well as 3-point harnesses for the rear passengers, excluding the center rear passenger. The Sport Coupe was a sportier style of the Sentra. It shared none of the body components with the standard model and was always imported from Japan, rather than being built in Tennessee. It was only available with the E16i or GA16i. All Sport Coupes had dual sway bars, dual remote-adjust mirrors, and a tachometer instrument cluster. The SE model added features like air conditioning and rear speakers. All B12 Sentras used the same wiring harness, regardless of the options
