19 MPG combined is what you get with the 2019 Chrysler 300 with the 5.7L Hemi V8. You’re not buying this car because you’re prioritizing fuel efficiency; you’re buying it for its blend of traditional American sedan swagger, satisfying V8 rumble, and surprisingly accessible price point. It’s a statement, a throwback, and a comfortable cruiser all in one, and for its dedicated fanbase, fuel consumption considerations take a backseat.

City and highway performance

The EPA estimates of 16 MPG in the city and 25 MPG on the highway reveal a compromise. The city figure shows the Hemi’s thirst when dealing with stop-and-go traffic; the engine’s displacement simply demands more fuel to get moving from a standstill, even with cylinder deactivation. The highway number, however, is respectable. The eight-speed automatic transmission allows the engine to cruise at relatively low RPMs, and the inherent efficiency of a large-displacement engine at steady state minimizes fuel consumption. These numbers reflect consistent driving habits that most owners should expect to see.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Chrysler 300 5.7L at $2,750. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes fuel prices based on the national average, which, of course, fluctuates throughout the year. This number provides a useful benchmark for budgeting, but your actual fuel expenses will vary depending on your driving habits and local fuel costs.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy for the 2019 Chrysler 300 5.7L can vary significantly. Driving aggressively will quickly lower those numbers. Constant hard accelerations and aggressive driving will keep the engine in its less-efficient operating range. Conversely, smooth acceleration, anticipation of traffic flow, and a focus on maintaining consistent speeds will yield results closer to, or even slightly better than, the EPA estimates.

If you do a lot of city driving, realistically expect to see numbers closer to the 16 MPG mark. Consistent highway drivers could see averages around 25 MPG or even higher with careful use of cruise control.

How it compares

Compared to other large sedans, the 2019 Chrysler 300 5.7L isn’t a fuel-sipping champion. The Nissan Maxima, with its 3.5L V6, achieves a combined EPA rating of 24 MPG. Even a similarly sized sedan like the Toyota Avalon, equipped with its 3.5L V6, manages 26 MPG combined. Within the Chrysler family, checking all Chrysler fuel economy data will reveal more efficient options; however, these vehicles don’t offer the same classic American sedan experience, rear-wheel drive configuration or V8 grunt as the 300. The Dodge Charger, mechanically similar and often cross-shopped, offers comparable fuel economy with its 5.7L Hemi. When looking at 300 MPG across all years, fuel economy has remained relatively consistent across generations of this model. The key takeaway is that buyers of the 300 5.7L are typically prioritizing something other than outright fuel efficiency.

Tips to maximize efficiency

One of the simplest ways to improve fuel economy in the 2019 Chrysler 300 5.7L is to drive smoothly. Rapid acceleration and hard braking waste fuel. Anticipate traffic flow and maintain a consistent speed whenever possible. Avoid unnecessary idling because this burns fuel without moving the vehicle. If you know you’ll be stopped for more than a minute, turn off the engine.

Regular maintenance is critical for optimal fuel efficiency. Ensure your tires are properly inflated, as underinflated tires increase rolling resistance and reduce fuel economy. Keep up with scheduled oil changes and air filter replacements, as these components directly impact engine performance and efficiency. Using the recommended grade of gasoline will also help maintain optimal performance.

Take advantage of the eight-speed automatic transmission. These transmissions are designed to keep the engine in its most efficient RPM range. Avoid aggressive use of the accelerator pedal that forces the transmission to downshift unnecessarily. Let the transmission do its job and shift smoothly through the gears.

Consider your route. Avoiding congested areas and choosing routes with less stop-and-go traffic can significantly improve fuel economy, especially in city driving. Planning your trips and using navigation apps to find the most efficient routes can save you fuel and time.
