23 MPG combined is an acceptable fuel economy figure for the 2019 Chrysler 300 with the 3.6L V6. To be clear, buyers aren’t choosing this car for Prius-like efficiency. They’re choosing it for its imposing presence, comfortable ride, and surprisingly good value for a large sedan. The fuel economy is simply something they’re willing to live with to get those attributes.

City and highway performance

The 3.6L V6 and eight-speed automatic transmission work well together to provide adequate power in most situations. The EPA estimates 19 MPG in the city and 30 MPG on the highway. The highway number is respectable and achievable, especially on long road trips. City driving, however, tends to drag down the overall average, given the car’s weight and the engine’s need to work harder in stop-and-go traffic. While the V6 is a willing partner, it’s still tasked with motivating a large car, and that takes fuel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Chrysler 300 3.6L to be $1,900. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that your actual fuel costs will vary depending on your driving habits, local fuel prices, and how often you use features like air conditioning that can impact fuel consumption. Using premium fuel will not improve fuel economy in this engine.

Real-world expectations

The EPA provides a standardized testing protocol, but real-world fuel economy can vary significantly, as you know. Conservative drivers who spend more time on the highway and anticipate traffic can certainly achieve close to 30 MPG on long trips. However, aggressive driving, frequent short trips, and lots of idling can easily drop the observed MPG into the high teens. The key to maximizing fuel economy in the 300 is to drive smoothly and avoid unnecessary acceleration and braking. Always check your tire pressure!

How it compares

The Chrysler 300 competes in a dwindling segment of large sedans. Compared to its closest rivals, the 300’s fuel economy is generally competitive, but not class-leading. The Dodge Charger, which shares many components with the 300, achieves similar fuel economy numbers with its V6, though the Charger’s available V8 engines are significantly thirstier. A Toyota Avalon, though not quite as traditionally styled as the 300, delivers around 26 MPG combined, offering a notable advantage to buyers prioritizing less gas. Even smaller sedans like the Honda Accord 2.0T can achieve up to 30 MPG combined, showcasing the compromises inherent in opting for a large car with a powerful engine. Review 300 MPG across all years for more perspective, and check all Chrysler fuel economy data to compare against other models made by this manufacturer.

Tips to maximize efficiency

One simple thing you can do for better mileage is ensuring your tires are properly inflated. Check the sticker on the driver’s side doorjamb for the recommended pressure and maintain it. Underinflated tires create more rolling resistance, which forces the engine to work harder and consume more fuel.

Aggressive driving habits such as rapid acceleration and hard braking can significantly reduce fuel economy. Instead, try to accelerate smoothly and maintain a steady speed whenever possible. Anticipate traffic flow and avoid unnecessary braking by coasting to red lights and stop signs.

Excessive idling wastes fuel. If you’re stopped for more than a minute or two, it’s generally more fuel-efficient to turn off the engine, especially if you’re running the air conditioning. Modern engines are designed for quick restarts and don’t need to warm up for an extended period before driving.

Reduce the amount of weight you carry in your vehicle. Extra weight increases the engine’s workload. Remove any unnecessary items from your trunk and passenger compartment. Every little bit helps improve fuel economy.

Use cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration. Cruise control can help you achieve optimal fuel economy on long drives by preventing variations in speed that can waste fuel, but remember to shut it off when driving in the rain to avoid hydroplaning.
