How many miles can a 2014 Chevy Impala go on a full tank?
On a full 18.5-gallon tank, a 2014 Chevy Impala typically travels about 400 to 570 miles, depending on which engine you have and how you drive.
To understand this range, it helps to know the fuel tank size and the different fuel economy figures for the two main engine choices offered in 2014. The Impala’s tank holds 18.5 gallons, and the available engines deliver different city, highway, and combined mpg ratings that affect total range.
Tank size and fuel economy by engine
The following estimates assume a full 18.5-gallon tank and typical EPA-style fuel economy figures. They illustrate the potential driving range on a full tank for each engine when operated under common conditions.
2.5L four-cylinder
For the 2.5L four-cylinder, which emphasizes highway efficiency, consider these ranges based on typical EPA-style figures.
- Estimated city-range: about 390–463 miles (18.5 gallons × 21–25 mpg city).
- Estimated highway-range: about 574–666 miles (18.5 gallons × 31–36 mpg highway).
- Estimated combined-range: about 520–540 miles (18.5 gallons × ~28–29 mpg combined).
These figures are approximate and depend on exact EPA ratings for your trim, load, terrain, and driving style.
3.6L V6
For the 3.6L V6, which prioritizes power, the ranges look different due to higher city fuel use and solid highway efficiency.
- Estimated city-range: about 333 miles (18.5 gallons × 18 mpg city).
- Estimated highway-range: about 555 miles (18.5 gallons × 30 mpg highway).
- Estimated combined-range: about 425 miles (18.5 gallons × ~23 mpg combined).
As with the four-cylinder, these are approximate figures that can vary with driving conditions, cargo, weather, and maintenance.
Estimating your own range
Use these steps to tailor the estimate to your actual car and driving habits.
- Identify your exact engine and the corresponding EPA ratings (city, highway, and combined) from the window sticker or manufacturer data.
- Multiply the 18.5-gallon tank capacity by the combined mpg to estimate total range on a full tank.
- For city-heavy driving, multiply by the city mpg; for highway-heavy driving, multiply by the highway mpg to get a more realistic range in those conditions.
These steps help you arrive at a personalized estimate that reflects how you typically drive your Impala.
Notes and caveats
Real-world range can vary due to factors like trip length, traffic, elevation changes, payload, tire condition, and air conditioning use. The figures above assume optimal fuel economy for the model year and configuration.
Summary
The 2014 Impala can typically cover roughly 400 to 570 miles on a full 18.5-gallon tank, with the exact figure depending on engine choice and driving conditions. Highway driving generally yields longer ranges than city driving, and your personal range will vary with load and terrain. For the most accurate estimate, check your trip computer or the vehicle’s window sticker for your specific configuration.
