23 MPG combined isn’t going to win any awards, but it’s a perfectly acceptable figure for the 2015 Chrysler 300 with the 3.6L V6. This isn’t a Prius competitor, nor is it trying to be. The 300 caters to buyers who prioritize space, comfort, and classic American sedan styling over frugality. For them, 23 MPG represents a reasonable trade-off for the 300’s other virtues.

City and highway performance

The EPA estimates the 2015 Chrysler 300 3.6L achieves 19 MPG in city driving and 30 MPG on the highway. The 19 MPG city figure is largely influenced by stop-and-go traffic, the engine’s displacement, and the car’s overall weight. The 30 MPG highway rating highlights the benefits of the smooth-shifting 8-speed automatic transmission. At cruising speeds, the transmission allows the engine to operate at lower RPMs, increasing efficiency. These figures are achieved in optimal testing conditions; expect variations based on driving style and local conditions.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2015 Chrysler 300 3.6L is $1,900. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. Of course, your actual fuel costs will fluctuate depending on how much you drive, the type of driving you do (city vs. highway), and the ever-changing price of gasoline in your area. If you live in an area with higher fuel costs or drive significantly more than the average, your annual fuel expenses will be higher.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy often differs. Drivers of the 2015 Chrysler 300 3.6L frequently report figures that are close to the EPA estimates, but variations are expected. Aggressive driving habits, frequent short trips, carrying heavy loads, and even tire inflation can impact fuel consumption. The age and condition of your specific vehicle will also play a role. Owners who prioritize smooth acceleration, anticipate traffic, and keep their 300 well-maintained are more likely to approach or even exceed the EPA figures.

How it compares

Compared to other large sedans of its time, the 2015 Chrysler 300 3.6L finds itself in the middle of the pack in terms of fuel economy. For example, the 2015 Toyota Avalon, another popular choice in this segment, achieves an EPA-estimated 21 MPG city and 31 MPG highway. The Chevrolet Impala with the 3.6L V6 is rated at 19 MPG city and 29 MPG highway, almost identical to the 300. Buyers considering the Chrysler 300 are often weighing its fuel economy against its styling, the comfortable ride quality, and the availability of rear-wheel drive, features not always found in its competitors. If you’re looking at all Chrysler fuel economy data, you’ll notice that the 300’s mileage is generally better than Chrysler’s larger SUVs and trucks, but naturally lower than smaller, more economy-focused vehicles like the Chrysler 200. Across 300 MPG across all years, this generation sits relatively average overall.

Tips to maximize efficiency

Regular maintenance is critical for optimizing the fuel economy of your 2015 Chrysler 300. Ensure that your car’s engine air filter is clean and replace it according to the manufacturer’s recommendations. A clogged air filter restricts airflow to the engine, forcing it to work harder and burn more fuel.

Proper tire inflation can also make a noticeable difference. Check your tires monthly and inflate them to the pressure specified on the sticker located on the driver’s side door jamb. Underinflated tires increase rolling resistance, which lowers fuel economy.

Avoid aggressive acceleration and braking. The 3.6L V6 in the 300 provides reliable power, but using it abruptly wastes fuel. Drive smoothly and anticipate traffic conditions to minimize unnecessary acceleration and deceleration. Also, resist the temptation to use “Sport” mode unless you really need the extra responsive performance.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t be causing undue wear and tear. Excessive idling consumes fuel without covering any distance. The 300 has a large engine that will waste significant fuel when left idling for long periods of time.

Consider using cruise control on the highway. Maintaining a consistent speed helps to optimize fuel economy. However, be mindful of traffic conditions and disengage cruise control when necessary to maintain a safe following distance.
