This generation Maxima was fitted with an independent rear suspension, and continued to offer the road scanning, electronic Super Sonic Suspension (sonar). The digital touch entry system on the GXE (in conjunction with the new Luxury Package) allowed the windows to be lowered and the moon roof opened from outside the vehicle on a keypad integrated on the front door handle, without the key in the ignition. One of the industry's first heads up displays was also included in the package, for model years 1989-92. The system projected a holographic image of the vehicles speed on a small screen in the windshield. The VE30DE engine was exclusively offered on the 1992–1994 Maxima SE. It was a 3.0-liter, 24 valve, DOHC motor. Its iron block was topped with aluminum cylinder heads and featured a dual length intake manifold (5-speed model only), variable intake valve timing, coil on plug ignition, plus a limited-slip differential. The VE30DE was rated at at 5600 rpm and at 4000 rpm, and had a 6500 rpm redline. SE models include white-faced gauges, twisted-spoke turbine wheels (.5 inch wider than GXE wheels and similar in design to wheels offered on the Z31 300ZX), body-colored grille, twin-tip mufflers, factory-tinted tail lights, black trim replacing chrome, firmer sport suspension, and optional 5-speed manual transmission.

The SE also had a rear spoiler and black side mirrors, whereas the GXE has body-color side mirrors. During this year, the Maxima was first introduced to the European market, replacing the Laurel. For European markets, the model range was: 3.0, 3.0 S, and 3.0 SE. Nissan Australia began importing the J30 series for a May 1990 release to replace the locally assembled Nissan Skyline (R31) sedan and station wagon.
