The 2006 Chevrolet Impala is a part of the brand's seventh generation mid-size sedans. Engine options include a 3.9L V6 with 240 horsepower and a 5.3L V8 with 303 horsepower, both mated to a 4-speed automatic transmission. Front wheel drive is standard across all three trims which are LS, LT, and SS. The LT trim is further divided into 1LT, 2LT, and 3LT based on feature level. Key safety features include advanced airbag system and anti-lock disc brakes, though modern safety features can be missed given the model year. For infotainment, it gets a 6-speaker audio system with a CD Player and optional satellite radio. Notable changes for 2006 include a redesign with more aggressive styling and an improved interior quality over the previous model year.
