Changes for 1972 included a revised grille without the central divider of the 1970 and 1971 items, new surface-mounted sidemarker lights rather than the previous flush-mount units, a new instrument cluster featuring a large rectangular speedometer and several small round gauges; the AM/FM radio option returned. The Demon had new fender-mounted metal "Demon" badges without the small devil character on the 1971 decals. The "Demon" decal on the rear of the car was replaced by DODGE and DART emblems on the lower right edge of the deck lid. Some Demons with the side and rear panel tape stripes retained the tape devil character. A new optional single hood scoop replaced 1971's dual scoops, and was coupled with a hood paint blackout that had been standard on the 1971 high-trim/high-value Demon Sizzler model. Cars equipped with the optional rally wheels now came with newly restyled center caps finished in a light argent (silver) paint.
