How many miles does a 2011 Chevy Impala get?
The 2011 Chevy Impala typically delivers in the low-to-mid 20s miles per gallon overall, with variations by engine and driving conditions. In general, you can expect roughly 23–24 mpg combined with the 3.5-liter V6 and about 21–22 mpg combined with the 3.9-liter V6, while highway figures trend higher for the smaller engine. Real-world results can vary based on maintenance, driving style, and load.
Engine options and fuel economy
Two V6 engines were offered for the 2011 Impala, both paired with front-wheel drive. The following EPA estimates reflect city/highway ratings and the combined figure for each engine.
EPA estimates by engine
- 3.5-liter V6 (FWD): approximately 19–20 mpg in the city and 29–30 mpg on the highway, for a combined around 23–24 mpg.
- 3.9-liter V6 (FWD): approximately 17–18 mpg in the city and 27–28 mpg on the highway, for a combined around 21–22 mpg.
Overall, the 3.5L V6 tends to yield better highway efficiency and a slightly higher combined mpg than the larger 3.9L V6, though both configurations stay in the low-to-mid 20s in typical mixed driving.
Real-world performance and driving factors
EPA numbers are estimates under controlled conditions. Actual mileage depends on several variables that drivers regularly notice in daily use.
- Driving habits: Gentle acceleration and steady cruising improve mpg; frequent hard accelerations and aggressive braking reduce it.
- Terrain and traffic: City stop-and-go traffic lowers mpg more than steady highway miles.
- Maintenance and condition: Proper tire pressure, clean air filters, and regular tune-ups help maintain fuel efficiency.
- Load and accessories: Extra weight (passengers, cargo) and roof racks can lower mpg.
- Climate: Extreme temperatures can affect fuel economy, especially if you use climate control heavily.
In practice, owners may see mileage that is lower or occasionally higher than the EPA estimates depending on these factors and the specific trim level they own.
Summary
The 2011 Chevy Impala offers two V6 engines with EPA estimates roughly in the low 20s combined: about 23–24 mpg with the 3.5L and around 21–22 mpg with the 3.9L. Real-world mileage varies by driving conditions, maintenance, and payload, but the Impala generally delivers respectable highway efficiency for a full-size sedan of its era.
