19 MPG combined. That’s the headline fuel economy number for the 2022 Chrysler 300 equipped with the 5.7L Hemi V8. It’s a figure that won’t register with someone shopping for a Prius, but it’s an accepted compromise for the buyer drawn to this American sedan. The 300 V8 isn’t about saving money at the pump; it’s about classic, comfortable motoring with readily available power.

City and highway performance

The EPA estimates the 2022 Chrysler 300 V8 gets 16 MPG in the city and 25 MPG on the highway. The city figure reflects the engine’s consumption when accelerating from stoplights and navigating urban environments. The highway number, while not stellar, is respectable, aided by the eight-speed automatic transmission that allows the engine to cruise at lower RPMs. Stop/start technology is only on V6 models, and Chrysler prioritizes smooth acceleration over maximizing every drop of fuel, especially in cities with many traffic lights.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Chrysler 300 V8 at exactly $2,750. This is based on driving 15,000 miles per year and using national average fuel prices. The actual cost will vary depending on your driving habits and the price of gasoline in your area. Someone who drives short distances in heavy traffic will likely exceed this estimate, while someone who spends most of their time on the open highway might see a slightly lower annual fuel bill.

Real-world expectations

While the EPA ratings are a benchmark, real-world fuel economy will fluctuate. Aggressive driving, frequent hard acceleration, and carrying heavy loads will negatively impact fuel consumption. However, a smoother driving style, anticipating traffic flow, and ensuring proper tire inflation can help you get closer to the EPA estimates. Owners give a wide range of MPG figures, but those who consistently achieve numbers below the EPA ratings are likely enjoying the Hemi’s power. The 300 is easy to drive at a relaxed pace, it is also easy to drive it aggressively. The choice is yours.

How it compares

In the world of large sedans, the Chrysler 300 V8 has limited competition. The Dodge Charger, sharing the same platform and engine, posts similar fuel economy figures. Other vehicles that offer similar performance include larger SUVs and pickup trucks, but their fuel economy is typically worse. For example, a V8-powered Chevy Tahoe struggles to hit even 20 MPG combined, highlighting the efficiency of the 300’s aerodynamic sedan shape. A BMW 540i might offer similar performance and luxurious amenities, it commands a higher price and its slightly better fuel economy (around 25 MPG combined) won’t offset the difference in purchase price for most buyers. You can view 300 MPG across all years to see if other models are better for fuel economy.

Tips to maximize efficiency

Gentle acceleration is key. The 5.7L V8 delivers ample performance even without hard pressing on the accelerator. Ease onto the throttle and allow the eight-speed automatic to shift through the gears. Avoid sudden bursts of acceleration unless necessary, as these maneuvers can reduce fuel economy.

Maintain a steady speed on the highway. Using cruise control can help prevent unnecessary speed fluctuations that waste fuel. Avoid frequent lane changes and minimize braking by anticipating traffic flow. A smooth pace is the efficient way to cover long distances in the 300.

Ensure your tires are properly inflated. Underinflated tires create more rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels (found on the doorjamb sticker). Proper tire inflation also improves handling and extends tire life.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines restart quickly and efficiently, and idling consumes fuel without moving the car. For those only interested in economy, all Chrysler fuel economy data show the PHEV Pacifica is worth a look.

Minimize the use of accessories. Air conditioning, especially on hot days, puts a load on the engine. Use it sparingly and consider opening the windows or sunroof when possible. Other power-hungry accessories, such as heated seats and high-powered sound systems, can also contribute to reduced fuel economy.
