* Driving style: Aggressive acceleration and high speeds significantly reduce fuel economy.
* Vehicle condition: Properly maintained vehicles generally get better gas mileage. Things like tire pressure, engine tune-up, and air filter condition all play a role.
* Terrain: Driving uphill or in stop-and-go traffic will lower fuel economy.
That said, you can expect the EPA estimated fuel economy to be in the range of 16-18 mpg city and 22-25 mpg highway. Keep in mind that these are estimates, and real-world mileage may differ. You'll likely see lower numbers in city driving and potentially higher numbers on long highway trips at steady speeds.
