The 2005 Chevrolet Impala belongs to the eighth generation of Chevrolet's large sedan. The front-wheel drive Impala offers two engines; the base model is powered by a 180-hp 3.4-liter V6, while the LS and SS models boast a 200-hp 3.8-liter V6. A 4-Speed automatic transmission comes standard. Key safety features include anti-lock brakes, daytime running lights, and optional side airbags. The LS and SS models further enhance passenger comfort and entertainment with standard OnStar system, 6-speaker stereo with CD player, and keyless entry. Changes from the previous year include an improved interior with more ergonomic controls and upgraded materials.
