23 MPG combined isn’t going to win any fuel efficiency awards, but it’s what you get with the 2018 Chrysler 300 with the 3.6L V6, a car that prioritizes spaciousness, comfort, and classic American styling over outright frugality. This is for those who want a large sedan with a reliable engine and don’t mind paying a bit more at the pump.

City and highway performance

The EPA estimates for the 2018 Chrysler 300 3.6L V6 are 19 MPG in the city and 30 MPG on the highway. The eight-speed automatic transmission does a good job of keeping the engine in its sweet spot, contributing to decent highway numbers. The city figures are a realistic reflection of what to expect during stop-and-go driving. This isn’t a small, lightweight car designed for nimble maneuvering; it’s a substantial sedan that requires more energy to get moving and maintain speed in urban environments. The highway figure, however, makes this a comfortable and relatively efficient long-distance cruiser, ideal for road trips where space and comfort are important.

Annual fuel cost

The EPA factors in the official MPG estimates to calculate the estimated annual fuel cost, assuming 15,000 miles driven per year and the national average fuel price. For the 2018 Chrysler 300 3.6L V6, that figure comes out to $1,900. This is a useful benchmark for comparing with other vehicles in its class or considering the overall cost of ownership.

Keep in mind that individual driving habits and local fuel prices can significantly impact this estimate, but it provides a standardized point of comparison.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary depending on driving habits, road conditions, and maintenance. Drivers who frequently engage in aggressive acceleration or spend a lot of time idling in traffic are likely to see lower MPG numbers than those who prioritize smooth, consistent driving. Regular maintenance, such as ensuring proper tire inflation and keeping the engine tuned, can also help maintain optimal fuel efficiency.

Don’t be surprised if your actual MPG fluctuates a bit from the EPA estimates, those figures are generated under controlled laboratory conditions that don’t perfectly replicate real-world scenarios.

How it compares

Compared to its competitors, the 2018 Chrysler 300 3.6L V6 sits squarely in the middle of the pack. A similarly equipped 2018 Toyota Avalon offers slightly better fuel economy, rated at 25 MPG combined, thanks to Toyota’s engineering prowess and focus on efficiency. The 2018 Ford Taurus with its base 3.5L V6 achieves approximately 21 MPG combined, making the Chrysler 300 the slightly more efficient choice. Even all Chrysler fuel economy data shows that other models prioritize efficiency. The Dodge Charger, mechanically similar to the 300 but with a slightly more aggressive tune, achieves comparable numbers.

For 300 MPG across all years, it’s important to look at the overall picture when making a vehicle choice; fuel economy is only one factor among many. The 300 buyer understands that they are sacrificing some efficiency for the car’s signature styling and spacious interior.

Tips to maximize efficiency

Anticipate traffic flow and avoid sudden acceleration or braking. The Chrysler 300 is a heavy car, and excessive acceleration burns unnecessary fuel. Smooth, gradual inputs will help you conserve gas and maintain a more consistent speed.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the driver’s side doorjamb.

Reduce unnecessary weight. The heavier the car, the more fuel it consumes. Remove any unnecessary items from the trunk and interior to lighten the load.

Use cruise control on the highway. Maintaining a constant speed on the highway can significantly improve fuel economy. Use cruise control whenever possible to avoid fluctuations in speed and minimize fuel consumption. This is especially helpful on flat stretches of road.

Consider using a lighter touch on the accelerator. The 3.6L V6 offers adequate power for most situations. You don’t always need to mash the pedal to the floor. Learn to modulate the throttle and engine torque to your advantage, minimizing the need for aggressive downshifts and high RPMs.
