21 MPG combined is the key figure for the 2021 Chrysler 300 AWD with the 3.6L V6. It’s a number that won’t impress hybrid shoppers, but it’s respectable for a large, all-wheel-drive sedan that prioritizes comfort and a classic American driving experience. Buyers drawn to the 300 aren’t typically chasing maximum fuel efficiency; they value its spaciousness, smooth ride, and distinctive styling over squeezing every last mile from a gallon of gasoline.

City and highway performance

Fuel economy breaks down to 18 MPG in the city and 27 MPG on the highway. The city figure reflects the 300’s weight and the demands of stop-and-go traffic. The highway number, while not stellar, is reasonable considering the car’s size and the fact that it’s sending power to all four wheels. The eight-speed automatic transmission helps to keep the engine in its optimal rev range, contributing to the decent highway performance. This powertrain is geared for effortless cruising, not drag strip heroics, and the MPG numbers reflect that priority.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Chrysler 300 AWD 3.6L V6 at $2,100. This figure is based on driving 15,000 miles per year and assumes current national average fuel prices. It’s a useful benchmark for comparing running costs with other vehicles. Your actual fuel expenses may vary depending on your driving habits, the type of roads you typically drive on, and local fuel prices; however, the $2,100 EPA estimate provides a solid starting point for budgeting.

Real-world expectations

While the EPA estimates are a good starting point, real-world fuel economy often differs. Some drivers have reported numbers slightly below the EPA estimates, especially in demanding driving conditions. Aggressive acceleration, frequent short trips, and extended idling can all negatively impact fuel consumption. Drivers who prioritize smooth, consistent driving and spend a significant amount of time on the highway may find that they meet or even slightly exceed the EPA’s 27 MPG highway rating. Understanding your own driving style is critical to predicting your 300’s real-world MPG.

How it compares

The 2021 Chrysler 300’s fuel economy is competitive within its segment, but it isn’t a class leader. The Nissan Maxima, for example, a front-wheel-drive sedan, achieves 20 MPG city and 30 MPG highway. The Toyota Avalon, another front-wheel-drive competitor, also nets around 22 MPG combined. If you look at all Chrysler fuel economy data, you can see that the 300 lags behind smaller, lighter models. The all-wheel-drive configuration of the 300 undoubtedly contributes to its lower MPG compared to the front-wheel-drive competition. For those interested in better fuel economy, other vehicles offer alternatives, but they lack the 300’s specific blend of size, style, and available all-wheel drive. Look through 300 MPG across all years to see how this has changed over time.

Tips to maximize efficiency

The Chrysler 300 with the 3.6L V6 and AWD is not going to be an economy car, but there are some methods you can use to squeeze out the most miles for your money. First, maintain a consistent speed and avoid excessive acceleration and braking. The 300’s weight and AWD system require more energy to get moving, and stopping frequently wastes fuel.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder, reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended PSI, which can be found on the sticker inside the driver’s side door.

Minimize idling. Modern engines don’t need long warm-up periods, and idling burns fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. Restarting uses less fuel than prolonged idling.

Lighten the load. Carrying unnecessary weight in your vehicle reduces fuel economy. Remove any items you don’t need from the trunk and back seat, as every extra pound adds up. The 300 is spacious, but don’t treat it like a storage unit!

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy, especially on long trips. Try it out to experience a smoother riding experience.
