21 MPG combined isn’t going to win any green awards, but that’s what you get with the 2020 Chrysler 300 AWD 3.6L. People don’t buy this car to save on gas; they choose it for its spaciousness, comfortable ride, and assertive presence. It’s a modern-day land yacht with all-wheel drive. Fuel efficiency is less important than these features. This specific configuration is for buyers who want a large, comfortable sedan that can handle bad weather and still look good.

City and highway performance

The 3.6L V6 in the Chrysler 300 gets 18 MPG in the city. Stop-and-go traffic reveals the engine’s appetite for fuel, especially given the added weight and drag of the all-wheel-drive system. The 300 does better on the highway, achieving 27 MPG. This difference shows how the engine can cruise efficiently at steady speeds. The eight-speed automatic transmission is important here, keeping the engine at optimal RPMs for fuel conservation during highway driving.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Chrysler 300 AWD 3.6L at $2,100. This is based on driving 15,000 miles per year, with a mix of city and highway driving, and assumes national average fuel prices. Your actual fuel costs will vary based on your driving habits and local gasoline prices. If you mainly drive in congested city traffic, you’ll probably spend more than $2,100. If you drive mostly on the highway, you might spend less.

Real-world expectations

EPA estimates are a starting point, but real-world fuel economy can change. Aggressive driving, frequent short trips, and heavy loads will hurt your MPG. On the other hand, gentle acceleration, anticipating traffic flow, and consistent speeds can help you get closer to the EPA ratings. Factors like tire pressure, vehicle maintenance, and even the weather matter. Tire pressure is especially critical in larger vehicles. Keeping your tires inflated can improve your gas mileage.

How it compares

The 2020 Chrysler 300’s fuel economy is competitive in the large, all-wheel-drive sedan category, but it’s not the best. The Nissan Maxima, with front-wheel drive only, gets a combined 24 MPG with its V6. The Toyota Avalon XLE, another front-wheel-drive competitor, gets around 26 MPG combined. The V6-powered Dodge Charger AWD has similar fuel economy, around 18 city and 27 highway. For those in the market for 300 MPG across all years, you’ll find a long history of vehicles in this segment prioritizing space and comfort over efficiency. This AWD version fits that pattern. Buyers looking at the 300 AWD aren’t always considering these more efficient FWD models. They want the extra confidence and traction of all-wheel drive and will accept the lower fuel economy.

Tips to maximize efficiency

Drive efficiently. The Chrysler 300 is a large vehicle, and quick acceleration or hard braking uses more fuel. Accelerate smoothly and anticipate traffic to improve your fuel economy. Leave plenty of space between you and the car in front of you and drive at a steady speed when you can.

Keep your tires inflated. Underinflated tires increase rolling resistance, making the engine work harder. Check your tire pressure at least once a month and inflate them to the pressure on the sticker on the driver’s side doorjamb. This is even more important with the weight of an AWD vehicle.

Remove extra weight. Extra weight in your trunk or back seat lowers fuel economy. Take out anything you don’t need and avoid using a roof rack if you don’t have to. A lighter vehicle uses less energy to accelerate and maintain speed.

Use the right drive mode. If your car has an “Eco” or “Fuel Saver” mode (check your owner’s manual), use it when possible. This mode typically changes the throttle response and transmission shift points to use less fuel. The car may feel slower, but it can help you get better MPG in some conditions.

Get regular maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s maintenance schedule for oil changes, air filter replacements, and spark plug replacements. Regular maintenance will keep your 3.6L V6 running smoothly for years. For all Chrysler fuel economy data, maintenance schedules are key to overall vehicle health.
