22 MPG combined from the 2017 Chevrolet Impala 3.6L isn’t going to win any hypermiling awards, but it’s a reasonable compromise for buyers prioritizing space, comfort, and a smoothly delivered 305 horsepower. This isn’t a car purchased by those obsessed with squeezing every last mile from a gallon of fuel, it’s a choice made by those who value a traditional large sedan experience, often foregoing the hybrid alternatives for a conventional powertrain.

City and highway performance

The Impala’s EPA ratings break down to 18 MPG in the city and 28 MPG on the highway. The city figure is understandably lower due to the engine working harder during stop-and-go traffic. The highway number, however, is respectable, indicating the Impala’s V6 settles into a relaxed and relatively efficient cruise at higher speeds. The six-speed automatic transmission plays a critical role here, selecting the optimal gear for the conditions and helping to keep the engine in its efficiency sweet spot on the open road. Just be aware that aggressive acceleration will quickly drop those numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Chevrolet Impala 3.6L at $2,000. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Your actual fuel costs will vary depending on your driving habits, the type of roads you typically travel, and local fuel prices. If you drive significantly more than 15,000 miles annually or live in an area with higher gas prices, your fuel expenses may exceed the EPA’s estimate. Conversely, if you drive fewer miles or live where fuel is cheaper, the annual cost could be less.

Real-world expectations

While the EPA estimates provide a useful baseline, your real-world fuel economy may differ. Factors like driving style, tire pressure, vehicle maintenance, and even weather conditions can influence your MPG. Owners who prioritize less gas and drive conservatively can often meet or even slightly exceed the EPA’s highway rating. However, those who frequently engage in spirited driving, carry heavy loads, or operate the vehicle primarily in city environments may see lower numbers. Monitoring your fuel consumption over time and adjusting your driving habits accordingly can help improve your real-world MPGs.

How it compares

In 2017, the large sedan segment offered a few alternatives to the Impala. The Toyota Avalon, similarly equipped with a V6, achieved a combined EPA rating of 24 MPG, slightly better than the Impala. A Nissan Maxima, also with a V6, matched the Avalon’s rating. These gains are marginal and come with potentially different trade-offs in terms of interior space or driving dynamics, depending on the buyer’s preferences. For example, the Chrysler 300 with its V6 offered a similar driving experience to the Impala, but with a slightly lower 23 MPG combined, at a price. For a full picture, review all Chevrolet fuel economy data, and don’t miss detailed IMPALA MPG across all years before making a decision.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel efficiency in the 2017 Impala. Avoid aggressive starts and hard braking, as these actions consume more fuel. Instead, gradually increase your speed and anticipate traffic flow to maintain a smoother, more consistent pace. The Impala’s V6 is responsive, but it doesn’t need to be pushed hard to deliver adequate performance in everyday driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Properly inflated tires also improve handling and extend tire life.

Reduce unnecessary weight inside the vehicle. Remove any items from the trunk or cabin that you don’t need to carry around regularly. Extra weight puts a strain on the engine and decreases fuel economy. A lighter vehicle is a more efficient vehicle.

Minimize idling. Idling for extended periods consumes fuel without moving the vehicle. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, so you don’t need to worry about excessive wear and tear from frequent restarts.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. By avoiding fluctuations in speed, cruise control allows the engine to operate more efficiently. However, avoid using cruise control in hilly terrain, as the vehicle may downshift frequently, negating some of the fuel-saving benefits.
