How many MPG is a Hellcat?

In brief, a Hellcat typically delivers about 16 mpg combined, with roughly 12–13 mpg in city driving and 21–23 mpg on the highway, though exact figures depend on model, year, and drivetrain.

What people often want to know about the Hellcat family is how a supercharged V8, producing well over 700 horsepower in most variants, can still be practical on the road. The answer varies by which Dodge you choose, as the lineup spans the Challenger, the Charger, and the Durango, with several trims that affect efficiency. Below is a concise guide to the most common configurations and their EPA estimates in recent years.

What is a Hellcat?

The Hellcat name denotes Dodge’s high‑performance family built around the 6.2-liter supercharged Hemi V8. The lineup includes the Challenger SRT Hellcat, Charger SRT Hellcat, and, in some years, the Durango SRT Hellcat, with horsepower ranging from about 707 to 797 in some variants. Fuel economy is a secondary consideration to performance, and EPA estimates reflect that emphasis by showing lower MPG than typical sporty or luxury sedans.

EPA fuel economy by variant

The following ranges summarize recent EPA estimates for the main Hellcat variants, recognizing that exact numbers vary by model year, drivetrain (including automatic vs. manual where offered), and equipment.

• Challenger SRT Hellcat (latest years with 8‑speed automatic): approximately 13 mpg city / 22 mpg highway / around 16 mpg combined.


• Challenger SRT Hellcat Redeye (and Jailbreak variants in some years): typically about 11–12 mpg city / 21–23 mpg highway / roughly 15–16 mpg combined.


• Charger SRT Hellcat (8‑speed automatic): around 12–13 mpg city / 21–23 mpg highway / about 16 mpg combined.


• Durango SRT Hellcat (where offered): roughly 11 mpg city / 17 mpg highway / about 13–14 mpg combined.

These figures illustrate the general trend: highway driving yields the best efficiency, city driving lowers it significantly, and higher-output variants typically sit toward the lower end of the range. Real-world mileage can vary based on driving style, tires, weather, and maintenance.

What factors affect mpg in a Hellcat?

Several variables influence the mpg you’ll actually see in a Hellcat, beyond the official numbers above. The most impactful include driving style, road conditions, and how aggressively you accelerate, as well as:

• Vehicle weight and aerodynamics — bigger, heavier versions like the Durango carry greater drag and weight.


• Transmission and gearing — automatic transmissions with multiple gears behave differently from any manual options, affecting efficiency.


• Tire choice and tire pressure — stickier tires used for performance grip can lower MPG, while proper inflation helps.


• Engine efficiency and octane requirements — higher-octane fuel is recommended for peak performance, and using it can influence efficiency and engine timing.


• Maintenance and condition — clean air filters, spark plugs, and timely oil changes help maintain optimal fuel economy.

Understanding these factors can help you set realistic expectations and plan fuel stops accordingly when owning or test-driving a Hellcat.

Tips to maximize mpg on a Hellcat

While you’re unlikely to rival the fuel economy of a mainstream compact, you can optimize efficiency through cautious changes in driving habits and maintenance.

• Drive smoothly with gradual starts and steady speeds, especially on highways.


• Keep tires properly inflated to the manufacturer’s recommended level.


• Follow recommended maintenance schedules and use the specified octane fuel for your engine variant.


• Minimize weight and avoid roof racks or heavy accessories that add drag.


• Use planned road trips to take advantage of long highway stretches for better average mpg.

These practices won’t transform a Hellcat into a high-efficiency vehicle, but they can help you pull a little more miles per gallon from the tank on everyday drives.

Bottom line

For most Hellcat variants, expect roughly 12–13 mpg in city driving, about 21–23 mpg on the highway, and around 16 mpg combined as a practical average. Specific numbers depend on the exact model year, trim, and drivetrain configuration. If fuel economy is a major consideration, review the EPA ratings for the precise vehicle you’re evaluating and weigh them against performance expectations.

Summary

The Hellcat family is defined by extreme power, not economy. While real-world numbers vary, most models deliver mid‑teens in combined MPG, with highway efficiency near the mid‑20s and city mileage in the low teens. Potential buyers should consult the exact EPA ratings for their preferred year and trim, and consider driving habits and maintenance as key factors in actual fuel economy.

Which car gets 70 MPG?

Several hybrid and diesel cars can achieve around 70 mpg, though it's often an official rating and can vary in real-world driving. Examples include the Vauxhall Corsa with a 1.5-litre turbo diesel engine, which can get up to 70.6 mpg, and various hybrid models, including some versions of the Hyundai Elantra Hybrid and Toyota Prius, which can reach this level under ideal conditions.
 
Examples of cars with around 70 mpg

• Vauxhall Corsa (1.5-litre turbo diesel): Can achieve up to 70.6 mpg, making it one of the most fuel-efficient diesel cars available. 
• Hyundai Elantra Hybrid: Early models were advertised with a claimed 70 mpg combined fuel economy. 
• Toyota Prius: Various models can get close to 70 mpg, especially older non-plug-in hybrids which are cheaper on the used market. Plug-in hybrid versions can also run on electric power for short distances. 
• Hyundai Ioniq Hybrid: Can achieve around 59 mpg combined. 

Important considerations

• Official vs. real-world MPG: The 70 mpg figure is often an official rating that is achieved under specific testing conditions, and your real-world mileage may be lower or higher depending on your driving habits, the vehicle's condition, and road conditions. 
• Hybrid vs. diesel: Both hybrid and diesel cars can achieve high MPG, but hybrids have the added benefit of electric-only driving for short distances, while some diesels can have higher upfront costs but offer impressive fuel economy on long-distance journeys. 
• Age and model: Some of the models with the highest MPG ratings are older, so be sure to research specific model years when shopping. 
• Type of driving: While hybrids and diesels can be very efficient, their fuel economy can vary significantly depending on whether you are driving in the city or on the highway. 

Which V8 gets the best MPG?

The most fuel-efficient V8 depends on the vehicle type, but the 2024 Chevrolet Silverado 5.3L V8 is a top contender among trucks, achieving 16 mpg city/22 mpg highway. For a high-performance sports car, the Lexus RCF has shown potential for impressive real-world efficiency, achieving 38.55 mpg in one eco-mode test, and the 2020 Corvette has reported up to 25 mpg. In the SUV category, the 2024 BMW X7 M60i is among the most efficient, with an EPA rating of 16 mpg city/21 mpg highway.

How far can a Hellcat go on a tank of gas?

Hellcat models get approximately 13 MPG city / 22 MPG highway, though real-world mileage can vary significantly based on driving style, with many drivers reporting closer to 15-18 MPG overall and some achieving over 25 MPG on the highway. The EPA ratings are based on a mix of city and highway driving, and the actual number depends heavily on how hard the car is driven, with some noting that using the "Eco" mode does not improve fuel economy as much as expected.
 
Official EPA ratings 

• City: Around 13 MPG
• Highway: Around 22 MPG 

Real-world mileage

• Average/Overall: Drivers often report around 15-18 MPG 
• Highway: It is possible to achieve 22-25 MPG or even higher on the highway if driven conservatively 
• City: Driving in the city will significantly lower the overall average, with some users reporting 16-18 MPG in mixed city/highway conditions 

Factors that influence mileage

• Driving style: Aggressive acceleration and hard driving will lower MPG considerably 
• "Eco" mode: While available, it may not significantly improve fuel economy, especially compared to a conservative driving style on the highway 
• Fuel tank size: The 18.5-gallon fuel tank combined with highway speeds can result in a driving range of over 420 miles, but this drops significantly with more aggressive driving
