19 MPG combined is what you get with the Dodge Challenger 5.7L. This isn’t a car people buy for sensible transportation; it’s a statement of intent, a rolling anachronism in a world of efficient hybrids and electric crossovers. The 5.7-liter HEMI V8 delivers a punchy dose of old-school muscle, and those who want that visceral experience understand the fuel economy trade-off and accept it willingly.

City and highway performance

The EPA estimates suggest 16 MPG in the city and 25 MPG on the highway for the 2018 Dodge Challenger 5.7L with its eight-speed automatic transmission. The city figure reflects the engine’s thirst during stop-and-go driving and idling, a common scenario for many Challenger owners who use the car for shorter commutes or weekend cruises. The highway MPG, while better, still pales in comparison to modern turbocharged four-cylinder engines. However, that highway number assumes you’re resisting the urge to tap into the readily available power, a restraint some drivers will find challenging.

Annual fuel cost

Using EPA figures, the estimated annual fuel cost for the 2018 Dodge Challenger 5.7L is $2,750. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this figure fluctuates with gas prices, and aggressive driving will certainly push that number significantly higher; the EPA numbers offer a useful benchmark for understanding the long-term running costs should you choose to embrace this powerful machine.

Real-world expectations

Forget the EPA numbers if you plan to fully exploit the 5.7L HEMI’s potential. Real-world fuel economy depends heavily on driving style. Frequent bursts of acceleration, spirited canyon runs, and extended idling will all contribute to lower MPG.

An owner who primarily uses the car for highway cruising and drives lightly might achieve closer to the EPA highway estimate. However, expect a realistic combined MPG closer to 16-18 if you enjoy the car’s performance. CHALLEGER MPG across all years provides further insight into how different model years compare based on user-submitted data.

How it compares

The 2018 Dodge Challenger 5.7L exists in a unique space. Compared to a modern muscle car like the Ford Mustang EcoBoost, which achieves around 25 MPG combined, the Challenger 5.7L sacrifices economy for a more traditional V8 experience. Even the Mustang GT, with its 5.0L V8, manages a slightly better 19 MPG combined. The Chevrolet Camaro LT1, packing a 6.2L V8, also gets 19 MPG combined.

The Challenger’s closest competitor, the Chrysler 300S with the 5.7L V8, manages similar fuel economy. For the Challenger buyer, the tradeoff is often seen as worthwhile: the rumble and instant torque of the HEMI is a key part of the car’s appeal and is not easily replicated by smaller, turbocharged engines. Buyers seeking less gas should consider all Dodge fuel economy data. This isn’t about cost savings; it’s about experiencing a specific type of power.

Tips to maximize efficiency

The eight-speed automatic transmission is your best ally in maximizing fuel economy. Drive in a relaxed manner, allowing the transmission to upshift early and keep the engine in its most efficient operating range. Avoid aggressive acceleration and hard braking whenever possible.

Tire pressure plays a significant role in fuel efficiency. Ensure your tires are properly inflated to the recommended pressure listed on the door jamb. Underinflated tires increase rolling resistance, reducing MPG.

Reduce unnecessary weight in the vehicle. Extra cargo in the trunk or rear seats adds to the vehicle’s overall load, requiring more energy to accelerate and maintain speed. Only carry essential items.

Plan your trips to avoid congestion and stop-and-go traffic. Consistent highway driving at a steady speed allows the engine to operate at its most efficient, yielding better fuel economy. Consider off-peak hours for errands or commutes.

Regular maintenance is critical. Ensure your engine is properly tuned and that components like spark plugs and air filters are in good condition. A well-maintained engine operates more efficiently, resulting in better fuel economy.
