23 MPG combined won’t lead the fuel economy charts, but it reflects the 2020 Chrysler 300 3.6L’s position: a stylish and comfortable large sedan that prioritizes presence and a smooth driving experience over pure efficiency. Buyers likely accept the mileage trade-off for its spacious interior, distinctive design, and available all-wheel drive.

City and highway performance

The EPA estimates for the 2020 Chrysler 300 with the 3.6L V6 show different numbers depending on the type of driving. Expect 19 MPG in the city. This isn’t terrible for a car of this size, but frequent stop-and-go traffic will decrease that number. On the highway, the 300’s efficiency improves considerably, reaching 30 MPG. The smooth-shifting eight-speed automatic transmission helps keep the engine at its optimal rev range at cruising speeds, improving fuel economy. Aggressive acceleration, even on the highway, will quickly diminish these numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Chrysler 300 3.6L is $1,900. This is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. This is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of roads you typically drive on, and the price of gasoline in your area. Drivers with longer commutes or those who spend more time in city traffic should expect to spend more than $1,900 annually. Consider this figure a baseline, not a guarantee.

Real-world expectations

The EPA has a standardized testing procedure, but real-world mileage often differs. Many 2020 Chrysler 300 3.6L owners report achieving figures near the EPA estimates, but driving style is significant. Drivers who accelerate quickly will struggle to match the 30 MPG highway figure. Careful driving is key to maximizing fuel efficiency in this car.

Factors like tire pressure, vehicle maintenance, and even the use of accessories like air conditioning can subtly impact gas mileage. Review 300 MPG across all years for owner experiences.

How it compares

The Chrysler 300 competes in a segment with dwindling options. The Nissan Maxima, another large sedan, achieves a slightly better 24 MPG combined. The Maxima lacks the 300’s available all-wheel drive and offers a sportier driving experience than the Chrysler’s luxurious feel. The Toyota Avalon, known for its reliability and comfort, also manages 26 MPG combined in its XLE trim. The Avalon Hybrid gets 43 MPG combined. The Dodge Charger, mechanically similar to the 300 but with bolder styling, shares the same 23 MPG EPA rating when equipped with its 3.6L V6. The 300 buyer values space, comfort, and classic American styling over the absolute best fuel economy.

Tips to maximize efficiency

One of the simplest ways to improve fuel economy is to drive smoothly. Avoid sudden acceleration and hard braking. The 300’s 3.6L V6 delivers adequate power, so there’s little need to push the engine aggressively. Anticipate traffic flow and maintain a steady speed to decrease fuel use. These habits alone can help your MPG get closer to the EPA estimates.

Proper maintenance is critical. Make sure your tires are inflated to the recommended pressure (check the sticker on the driver’s side doorjamb). Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Regular oil changes and air filter replacements also improve engine performance and efficiency. See all Chrysler fuel economy data if you wish.

Reduce unnecessary weight by removing any cargo you don’t need from the trunk. Extra weight puts a strain on the engine, reducing fuel economy. This is relevant for a large sedan like the 300, where it’s easy to accumulate extra belongings in the spacious trunk without noticing the impact on mileage.

Avoid idling. If you’re stopped for more than a minute, it’s usually better to turn off the engine. Cars start quickly and reliably, and you’ll save fuel by not letting the engine run unnecessarily at idle. This is important in city driving if you are stuck at long traffic lights.
