21 MPG combined won’t excite hypermilers, but it’s relevant to buyers who appreciate a large, comfortable, and classically styled sedan with available all-wheel drive. The 2023 Chrysler 300, in this AWD 3.6L V6 configuration, isn’t about squeezing out every last mile. It’s about delivering a smooth, confident ride with enough power to handle most situations, at the cost of fuel consumption. Its goal is not green efficiency, but rather a comfortable, secure, and stately driving experience.

City and highway performance

The EPA estimates for city and highway driving reflect the Chrysler 300’s character. 18 MPG in the city indicates the engine works harder in stop-and-go traffic, typical of larger vehicles. The 27 MPG highway figure is more respectable, suggesting relaxed cruising and efficient performance when the engine isn’t constantly accelerating and decelerating. The 8-speed automatic transmission helps on the highway, keeping the engine in its most efficient RPM range. These numbers aren’t class-leading, but they are realistic given the 300’s size, weight, and the presence of all-wheel drive, which inherently adds friction and consumes more fuel than a RWD system. Understanding this trade-off is key to appreciating this car.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Chrysler 300 AWD 3.6L V6 at $2,100. This calculation is based on driving 15,000 miles per year and assumes national average fuel prices. Remember that this is an estimate, and your actual fuel costs will vary depending on your driving habits, the type of driving you do (city versus highway), and the price of gasoline in your area. Aggressive driving, prolonged idling, and consistently driving in heavy traffic will all increase your annual fuel expense beyond that $2,100 mark. However, a driver who spends most of their time cruising on the highway could potentially beat that estimate. Unlike some cars, the 300 doesn’t require premium fuel; it is designed to run on regular unleaded. You can find all Chrysler fuel economy data on our site.

Real-world expectations

While the EPA estimates offer a standardized comparison, real-world fuel economy often differs. Drivers of the 2023 Chrysler 300 AWD typically report figures close to the EPA estimates, but variables such as driving style, tire pressure, and even ambient temperature can impact the final number. Using accessories that draw power, such as the climate control system, can also subtly reduce fuel efficiency. Owners who prioritize smooth acceleration and anticipate traffic flow often report better mileage than those with a more aggressive driving style. All-wheel drive is primarily there for inclement weather, and it impacts efficiency; disengaging it if possible can help with fuel economy. Tire inflation plays a surprisingly noticeable role; correctly inflated tires reduce rolling resistance and improve MPG.

How it compares

Compared to its competitors, the 2023 Chrysler 300 AWD’s 21 MPG combined rating paints a specific picture. For example, the Toyota Avalon, a front-wheel-drive sedan, achieves a combined 26 MPG with its standard V6 engine. The Nissan Maxima, another FWD option, gets around 24 MPG combined. The Dodge Charger, sharing a platform with the 300, can achieve similar numbers if equipped with its RWD V6, but opting for the more powerful V8 engines will significantly decrease fuel economy. These comparisons highlight that the 300’s AWD system contributes to its lower fuel economy compared to front-wheel-drive rivals. The all-wheel-drive variants of other full-size sedans, such as the discontinued Ford Taurus, typically fall within a similar MPG range. Someone choosing the 300 isn’t prioritizing ultimate fuel efficiency; they’re prioritizing the confidence and sure-footedness that AWD provides, even with the modest hit to fuel economy. They’re also likely drawn to the 300’s classic American sedan styling, a design that sets it apart from the more streamlined and modern aesthetics of some of its competitors.

Tips to maximize efficiency

Gentle acceleration and braking are critical. Avoid sudden bursts of speed and hard stops. The 300 has enough mass that smooth inputs are rewarded not just with better fuel economy but with a more comfortable ride for you and your passengers. Anticipate traffic flow to minimize unnecessary acceleration and braking maneuvers.

Maintain proper tire inflation. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the doorjamb sticker. Underinflated tires increase rolling resistance, which reduces fuel economy. This is important on a car with the 300’s heft.

Minimize idling time. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel without benefiting the engine.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy, especially on long drives. However, be mindful of hilly terrain, as cruise control may downshift aggressively to maintain speed, negating some of the fuel savings.

Keep up with routine maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug maintenance. A poorly maintained engine can waste fuel and decrease performance.
