For 1993, Nissan replaced the Stanza with the Altima. The major improvement over the Stanza was an extra inch of rear leg room and head room. The compact Altima was offered in four versions: base, step-up GXE, sporty SE, and deluxe GLE. The only available engine was a revamped version of the Stanza's 2.4-liter twin-cam 4-cylinder. When installed in the Altima, it provided 150 horsepower. A 5-speed manual was standard on all models except the flagship GLE version, which came standard with the 4-speed automatic that was optional on the three lower trim levels. A driver-side airbag came standard and when optional antilock brakes were ordered, rear disc brakes replaced the standard rear drums.
