The Chevelle Malibu was redesigned for 1973 along with the rest of the Chevelle models (Deluxe and Laguna), accounting for the biggest change in the model since the Chevelle hit the market in 1964.

This new body design featured a new roof line, revised front and rear ends, distinct rear quarter glass for 2-door models and new side windows split with center pillars on 4-door models, a body that was 5 inches longer and an inch wider, and greatly improved visibility over previous models. There was also the addition of the new federally mandated 5mph bumpers.
