21 MPG combined isn’t going to win any fuel-sipping awards, but the 2017 Chrysler 300 AWD with the 3.6L V6 isn’t about squeezing every last drop out of a gallon of gas. This is a large, comfortable sedan with all-wheel drive, designed for effortless cruising and confident handling in all weather conditions. For buyers prioritizing space, style, and all-weather capability over ultimate economy, it represents a reasonable compromise.

City and highway performance

The EPA estimates for the 2017 Chrysler 300 AWD 3.6L reveal a split personality. 18 MPG in the city reflects the realities of moving a large, relatively heavy vehicle through stop-and-go traffic, and the 27 MPG highway rating is more respectable and achievable on long road trips, particularly when using the smooth-shifting eight-speed automatic transmission to its advantage.

While some might find these numbers underwhelming compared to smaller, lighter cars, they align with what’s expected from a large sedan with all-wheel drive from this model year.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Chrysler 300 AWD 3.6L to be $2,100. This is based on driving 15,000 miles per year and using national average fuel prices. This figure provides a useful benchmark for budgeting your transportation expenses, but remember that your actual fuel costs will vary depending on your driving habits, location, and prevailing fuel prices.

Aggressive driving, frequent short trips, and living in an area with high fuel costs will all push that $2,100 figure higher.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world MPG can vary significantly. Owners of the 2017 Chrysler 300 AWD 3.6L often report figures that are close to the EPA estimates, but this depends heavily on driving style and environment.

Expect slightly lower mileage during the winter months, particularly in regions that experience snow and ice, as the all-wheel-drive system works harder and winter-blend fuel has slightly less energy density. Regular maintenance, including tire inflation and air filter replacement, can also help maintain optimal fuel economy.

How it compares

In the large sedan segment, the 2017 Chrysler 300 AWD 3.6L sits roughly in the middle of the pack when it comes to fuel economy. Consider the Toyota Avalon, which achieves around 24 MPG combined in its front-wheel-drive configuration for similar model years, but you sacrifice the Chrysler’s available all-wheel drive. Conversely, a V8-powered Dodge Charger, aimed at a more performance-oriented buyer, might only achieve around 19 MPG combined.

Those considering the Chrysler 300 might also cross-shop it with SUVs like the Ford Explorer, which would offer similar space, all-wheel drive, but potentially slightly lower fuel economy in its four-cylinder form.

Tips to maximize efficiency

Drive smoothly and avoid aggressive acceleration. The 300’s 3.6L V6 delivers ample power, but using it all the time will take a toll on your MPG. Gentle acceleration and maintaining a steady speed are key to maximizing fuel efficiency, especially in city driving.

Take advantage of the eight-speed automatic transmission. This transmission is designed to keep the engine in its most efficient operating range. Avoid using manual shift mode unless necessary, and let the transmission do its job. It is also important to ensure the transmission is properly maintained and has no leaks.

Maintain proper tire inflation. Underinflated tires create more rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the manufacturer’s recommended level, typically found on a sticker on the driver’s side doorjamb.

Reduce unnecessary weight. Carrying extra weight in your trunk or backseat reduces fuel economy. Remove any items you don’t need to lighten the load and improve your MPG. The extra weight forces your engine to use more power to move.

Consider the drive mode, if equipped. If your 300 is equipped with a drive mode selector, experiment with different modes to see which offers the best blend of performance and fuel economy for your driving style. Typically, the “Eco” or “Normal” modes will optimize fuel consumption.
