An EPA combined rating of 18 MPG isn’t going to win any fuel economy awards, and the type of driver who buys a 2020 Dodge Charger with the 6.4L Hemi isn’t really expecting it to. This isn’t a car purchased for sensible commutes or maximizing gas mileage. It’s a modern muscle car, a four-door throwback to a bygone era, purchased for its performance, its aggressive styling, and the primal satisfaction that comes from putting your foot down and hearing that V8 roar. Fuel economy is, at best, a secondary consideration.
City and highway performance
The EPA estimates break down to 15 MPG in the city and 24 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the Charger’s hefty engine and aggressive tuning take their toll. The highway number is more respectable, aided by the 8-speed automatic transmission which allows the engine to cruise at lower RPMs. However, maintaining that 24 MPG requires a disciplined right foot. Any temptation to use the Hemi’s prodigious power will send that number tumbling down quickly. For those planning longer trips, it might be worth examining CHARGER MPG across all years to see if earlier models offer a significant fuel savings.
Annual Fuel Cost
The EPA estimates an annual fuel cost of $3,200 for the 2020 Dodge Charger 6.4L 8-cyl. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also uses the national average fuel price at the time of calculation. Of course, your actual fuel cost will vary depending on your driving habits, the type of fuel you use, and where you live. Those with longer commutes or a penchant for performance driving should expect to exceed this estimate, while those with shorter trips and a gentler driving style may find themselves closer to (or even below) the EPA’s figure.
Real-world expectations
Real-world fuel economy for the 2020 Dodge Charger 6.4L often deviates from the EPA estimates. Drivers who frequently use spirited acceleration or spend most of their time in heavy traffic can expect average fuel economy in the low teens. Those who prioritize efficiency and spend more time on the highway might see figures closer to the EPA’s 24 MPG. Remember that the Charger’s performance-oriented nature makes it particularly sensitive to driving style. A lead foot will be penalized severely at the pump.
How it compares
Compared to other large sedans, the Charger 6.4L’s fuel economy is predictably on the lower end. For example, the Toyota Avalon, a more comfort-oriented large sedan, achieves 22 MPG combined with its V6 engine. Even the Chrysler 300, which shares a platform with the Charger, manages slightly better fuel economy in most trims. A V6-powered 300 can achieve upwards of 23 MPG combined. Those seeking similar performance with potentially better MPG could consider the BMW 540i, which delivers comparable horsepower with a turbocharged inline-six and achieves around 25 MPG combined. However, none of these alternatives captures the same raw, unapologetic muscle car ethos that defines the Charger 6.4L. Those seeking to explore all Dodge fuel economy data will quickly see the tradeoff this vehicle makes.
Tips to maximize efficiency
Resist the urge to constantly accelerate hard. The 6.4L Hemi is incredibly responsive, making it tempting to use its power at every opportunity. However, smooth, gradual acceleration will significantly improve fuel economy. Treat the throttle with respect, and you’ll be rewarded with fewer trips to the gas station.
Use the Charger’s Eco mode when appropriate. This mode modifies the engine and transmission mapping to prioritize fuel efficiency over performance. While it does dull the throttle response somewhat, it can make a noticeable difference in MPG, especially in city driving and highway cruising.
Maintain proper tire inflation. Underinflated tires increase rolling resistance, which leads to lower fuel economy. Check your tire pressure regularly and inflate them to the recommended level, found on the sticker inside the driver’s side doorjamb. This is a simple but effective way to improve MPG.
Reduce unnecessary weight. Carrying extra cargo in the trunk or rear seats adds weight to the vehicle, which requires more energy to accelerate and maintain speed. Remove any items you don’t need to carry on a regular basis to reduce weight and improve fuel economy.
Consider premium fuel. While the Charger 6.4L doesn’t *require* premium fuel, using it can potentially improve performance and fuel economy, especially under heavy load or during spirited driving. The engine is designed to take advantage of the higher octane rating, which can result in a slight MPG increase. Experiment and see if it makes a difference for your driving style.
