Full specifications for the ninth-generation Chevrolet Impala (W-body, 2006-2013), by engine — the 3.5L and 3.9L V6s and the front-drive 5.3L V8 SS. All three used GM’s 4-speed automatic. Power and EPA figures are cross-checked; the 3.9L dropped from 242 hp (2006) to 233 hp when it gained variable valve timing in 2007, and the V8 SS rating fell with the 2008 EPA method change.
Each column is one specific vehicle — a single engine or motor and, where shown, body style. Dimensions and several weights are specific to that body and drivetrain; other body or powertrain versions differ, so match the column to your own vehicle.

Sources: Owner's manual. Where an owner’s manual or homologation figure exists it takes precedence; workshop data fills only what those omit.
A dash (—) means we haven’t verified that figure for that variant yet. Figures are US-market. GVWR and some capacities aren’t published by the maker for every model, so they may be blank; your door-jamb label is the authority for weights and tire pressures.
