In 2006, the Chevrolet Impala offered multiple engine options depending on the trim level. The lineup included a 3.5-liter V6, a 3.9-liter V6, and, in the performance-oriented Impala SS, a 5.3-liter V8.
The choice of engine in a 2006 Impala closely followed the model grade: base models tended to use a smaller V6, mid-range trims offered a larger V6 for more power, and the SS variant was equipped with a V8 designed for higher horsepower and torque. Most configurations used an automatic transmission, with gearing tuned to the engine.
The following section outlines the main engine options found in 2006 Impala models, including rough power ranges to help distinguish them.
- 3.5-liter V6 (gasoline) with sequential fuel injection, producing roughly 217 horsepower and about 214 lb-ft of torque. Standard on base models with a 4-speed automatic transmission.
- 3.9-liter V6 (gasoline) delivering around 240 horsepower and approximately 240 lb-ft of torque. Typically paired with mid-range LT trims and a 4-speed automatic.
- 5.3-liter V8 (gasoline, Vortec 5300) in the Impala SS, producing about 303 horsepower and roughly 323 lb-ft of torque. Paired with a 4-speed automatic transmission and marketed as the performance flagship.
In short, a 2006 Impala could be powered by a small to mid-size V6 or, in the high-performance variant, a V8. The exact engine depended on the specific trim and options the car had when it rolled off the lot.

The Impala SS was the only version in 2006 to feature the 5.3-liter V8, commonly referred to as the Vortec 5300. It produced around 303 horsepower and about 323 lb-ft of torque, delivering noticeably stronger acceleration than the V6-equipped models. This engine was paired with a 4-speed automatic transmission to balance power with everyday drivability.
Summary
The 2006 Chevy Impala offered three main engine configurations: a base 3.5L V6, an optional 3.9L V6, and the high-performance SS with a 5.3L V8. The exact engine depended on the trim, and all variants used an automatic transmission, with the SS delivering the strongest performance due to its V8 power.
