2018 Nissan Altima Exterior and Dimensions

The Altima sports bold dimensions that give the sedan an imposing figure, but it lacks the angular profile of many core competitors. The V-motion grille fits snugly between sharply styled halogen headlights. The front bumper extends aggressively ahead of the fascia but hangs quite low. Fog lights are embedded low within the fascia from the 2.5 SR upwards and LED clusters replace the standard headlights on the 3.5 SL. 18-inch steel wheels adorn the base S, while the SV and 2.5 SL ride on 17-inch alloys, and the SR and 3.5 SL are decked out with 18-inch alloys. The SR also shows off its sporty attitude with a trunk-mounted sport spoiler.

The Nissan Altima is quite long for a mid-size sedan, measuring in at 197.9 inches. Its width and height are more on par for the segment, at 72 inches and 57.8 inches respectively. The 2.5 SR adds 0.1 inches to the height, while the SL trims is 0.2 inches taller. Despite the car's extra length, its wheelbase is somewhat short at 109.3 inches. With a weight range of 3,212 lbs to 3,463 lbs, the Altima is on par with most rivals.
