What horsepower your Dodge Charger has depends on the model year and engine you choose

Dodge Charger horsepower varies significantly across model years and engine options. A base 2024 Charger with the 3.6-liter V6 produces 292 horsepower, while the 5.7-liter V8 generates 370 horsepower. The high-performance R/T models jump to 495 horsepower with the supercharged 5.7-liter engine, and the top-tier SRT Hellcat delivers 797 horsepower from its supercharged 6.2-liter V8. Older Chargers from the 1960s and 1970s ranged from around 150 horsepower in base models to over 400 in muscle car variants, while 2015–2023 models fell between 292 and 707 horsepower depending on trim.

The horsepower figure matters for acceleration, towing capacity, and fuel consumption. A higher-horsepower engine will accelerate faster and handle heavier loads, but it also typically costs more to purchase, insure, and fuel. Understanding what each engine produces helps you match the vehicle to your actual driving needs rather than paying for power you won't use.

  • Horsepower directly affects acceleration, fuel economy, insurance costs, and towing capacity across all model years.

Current generation Charger horsepower (2024 model year)

The 2024 Dodge Charger lineup offers four distinct horsepower levels across its engine options. The base SE and SXT trims use a 3.6-liter V6 that produces 292 horsepower and 260 pound-feet of torque. This engine is paired with an eight-speed automatic transmission and is designed for fuel efficiency and everyday driving rather than performance.

The GT and R/T trims step up to a 5.7-liter V8 that generates 370 horsepower and 395 pound-feet of torque in naturally aspirated form. The R/T model also offers a supercharged version of the same 5.7-liter engine that increases output to 495 horsepower and 525 pound-feet of torque. The SRT Hellcat, the top performance variant, uses a supercharged 6.2-liter V8 that produces 797 horsepower and 707 pound-feet of torque.

Horsepower in recent Charger generations (2015–2023)

From 2015 through 2023, Dodge offered Charger models with horsepower ranging from 292 to 707. The base V6 engine remained relatively consistent at around 292 horsepower throughout this period. The standard 5.7-liter V8 produced 370 horsepower, while the R/T supercharged variant delivered 485 to 495 horsepower depending on the specific year.

The SRT Hellcat, introduced in 2015, initially produced 707 horsepower. By 2021, Dodge increased this to 717 horsepower through refinements to the supercharger and fuel system. The Redeye variant, added later in the generation, matched the Hellcat's output. These high-performance models were designed to compete with the Chevrolet Camaro ZL1 and Pontiac Firebird Trans Am in terms of raw acceleration and top speed.

Classic Charger horsepower (1968–1974)

The original Dodge Charger generation, produced from 1968 to 1974, offered a wide range of engine options that reflected the muscle car era. Base models came with a 225-cubic-inch slant-six engine producing around 145 to 155 horsepower. The 318-cubic-inch V8 generated approximately 230 horsepower, while the 340-cubic-inch V8 produced around 275 horsepower.

The most powerful option was the 440-cubic-inch V8, which produced 375 horsepower in standard form and up to 390 horsepower in the high-performance 440 Magnum variant. The legendary 426-cubic-inch Hemi V8, available in select years, delivered 425 horsepower and became one of the most sought-after engines in muscle car history. These figures made the classic Charger competitive with the Chevrolet Chevelle SS and Plymouth Road Runner during the height of the American muscle car era.

How Dodge measures and rates horsepower

Dodge horsepower figures are measured at the engine's crankshaft using a dynamometer, which is a standardized testing device. The measurement is taken at a specific engine speed (typically around 5,000 to 6,000 RPM for V8 engines) and represents the maximum power the engine can produce under ideal conditions. This is called gross horsepower or SAE net horsepower, depending on the testing standard used.

The actual horsepower delivered to the wheels is lower than the engine's rated output because energy is lost through the transmission, differential, and drivetrain. This loss typically ranges from 10 to 15 percent on automatic transmissions. Dodge publishes the engine's rated horsepower, not the wheel horsepower, which is why a Charger advertised at 370 horsepower will deliver roughly 315 to 330 horsepower at the rear wheels when tested on a dynamometer.

Horsepower versus torque and what each means for driving

Horsepower and torque are often confused, but they measure different things. Torque is the twisting force the engine produces, measured in pound-feet, and it determines how quickly the car accelerates from a stop. Horsepower is the rate at which the engine can do work over time, and it determines how fast the car can go and how quickly it accelerates at higher speeds.

A Charger R/T with 495 horsepower and 525 pound-feet of torque will feel quick off the line because of the high torque, and it will continue accelerating strongly at highway speeds because of the high horsepower. A base Charger V6 with 292 horsepower and 260 pound-feet of torque will feel slower in both scenarios. For everyday driving, the difference is most noticeable during highway merging and passing, where the higher-horsepower engine reaches passing speed more quickly.

How horsepower affects fuel economy and insurance costs

Higher horsepower engines consume more fuel because they require larger displacements, more fuel injection, and higher compression ratios. The 2024 Charger V6 is rated for approximately 19 miles per gallon in the city and 30 on the highway, while the 5.7-liter V8 drops to around 16 city and 25 highway. The supercharged R/T variant falls to approximately 14 city and 22 highway, and the SRT Hellcat achieves roughly 12 city and 19 highway.

Insurance premiums also increase with horsepower because insurers view high-performance vehicles as higher risk. A 2024 Charger SRT Hellcat will cost significantly more to insure than a base V6 model, sometimes 50 to 100 percent more depending on your age, driving record, and location. If you drive fewer than 10,000 miles per year or primarily on highways, the fuel economy difference may be less noticeable, but the insurance cost difference will be when ready.

Frequently Asked Questions

What is the most powerful Dodge Charger ever made?

The 2021–2023 SRT Hellcat Redeye is the most powerful production Charger, with 797 horsepower. The original 1970 Dodge Charger 500 with the 426 Hemi engine produced 425 horsepower, which was the most powerful classic Charger. Modern supercharging technology allows the current generation to exceed the classic era by a significant margin.

Can I increase horsepower on my Charger through modifications?

Yes, but the extent depends on your engine type. V6 engines can gain 20 to 40 additional horsepower through intake and exhaust modifications. V8 engines can gain 30 to 80 horsepower with similar modifications. Supercharged engines like the R/T and Hellcat can be tuned for additional output, but modifications may void your warranty and affect reliability.

Does a 2024 Charger have more horsepower than a 2015 Charger?

The base engines are similar—both produce around 292 horsepower in the V6 and 370 in the standard V8. The 2024 R/T supercharged engine produces 495 horsepower compared to 485 in the 2015 model, a modest increase. The SRT Hellcat increased from 707 horsepower in 2015 to 797 in 2024, a significant jump of 90 horsepower.

What horsepower do I need for towing with a Charger?

The Dodge Charger is not designed as a towing vehicle—it is a performance sedan. The V8 models can tow up to 3,500 pounds with the proper hitch and brake controller, but the V6 is not rated for towing. If towing is a priority, a Dodge Ram truck or Durango SUV would be more appropriate choices.
