Launched as a 2006 model, the design features smooth lines. The big headlamps have a premium, jeweled appearance with three independent lighting units and are smoothly integrated into the front end. The tail lights are nicely integrated as well. These details complement other quality attributes, such as tight tolerances of 3.5 mm or less between body panels and substantial grab-style door handles that won't pinch your fingers or snap away from your hand on a cold morning. Flat-blade windshield wipers provide consistent pressure on the glass, which helps eliminate streaking and wind noise.
The LS, LT and LTZ are distinguished by exterior trim but share one front end design, while the SS sports a completely different design that includes a dual-split grille with SS-signature black-diamond crosshatch pattern. The Impala SS also features Corvette-inspired bright exhaust tips. A rear spoiler is standard on LTZ and SS models, and is available on LT.
