23 MPG combined is the fuel economy for the 2023 Chrysler 300 with the 3.6L V6. This isn’t going to win any awards, but it’s a figure the 300’s buyer accepts. This car is bought for its size, its swagger, and a dose of old-school American sedan character that’s increasingly rare. Buyers aren’t cross-shopping it against Prius Primes; they want a roomy, comfortable cruiser, and they value that above all else.

City and highway performance

The EPA estimates of 19 MPG in the city and 30 MPG on the highway show the 300’s dual nature. Around town, the car’s weight and the inherent inefficiencies of stop-and-go driving affect fuel economy. On the open road, the smooth-shifting eight-speed automatic transmission and reasonably aerodynamic shape let it stretch a gallon of gasoline further. Achieving that 30 MPG highway figure requires a light foot, however. Frequent bursts of acceleration will lower it. Those wanting to explore 300 MPG across all years should be aware that previous models had slightly different fuel economy ratings.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Chrysler 300 3.6L V6 is $1,900. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. It also assumes national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and prevailing fuel prices in your area. It’s a useful benchmark, but individual results will differ.

Real-world expectations

Don’t expect to consistently match the EPA figures. Aggressive driving, heavy traffic, and even something as simple as tire pressure can impact fuel economy. Real-world numbers tend to hover slightly below the official ratings, especially in areas with significant stop-and-go traffic. A lead foot will push that annual fuel cost north of the $1,900 estimate without breaking a sweat.

How it compares

The Chrysler 300 exists in a shrinking segment. The Nissan Maxima, with its 3.5L V6, manages 24 MPG combined, slightly better than the 300, but with slightly less road presence. The Toyota Avalon offered similar size and comfort, but those were discontinued after 2022. Some might consider a Kia Stinger GT-Line with its 2.5L turbo four, which gets 25 MPG combined, but that’s a smaller, sportier vehicle with a very different vibe. All Chrysler fuel economy data shows that the 300 is on the lower end of the MPG scale compared to other vehicles in its lineup.

Tips to maximize efficiency

The 300’s 3.6L V6 is a well-proven engine, but it does have a sweet spot. Accelerate smoothly and avoid abrupt throttle inputs. The eight-speed automatic is programmed to upshift quickly, so let it do its job and avoid stomping on the gas pedal unless absolutely necessary.

Ensure your tires are properly inflated. Check the sticker on the driver’s side doorjamb for the recommended pressure. Underinflated tires increase rolling resistance, which hurts fuel economy. A simple tire pressure gauge and inflator can pay for themselves quickly.

Minimize idling. Modern engines don’t need to warm up for extended periods in most weather conditions. If you’re stopped for more than a minute, consider turning off the engine. Excess idling burns fuel without moving the car.

Reduce unnecessary weight. Hauling around extra cargo in the trunk or back seat adds weight, which reduces fuel economy. Clean out any unnecessary items to lighten the load.
