What horsepower your Dodge Charger has depends on the year and engine you own
Dodge Charger horsepower varies significantly across model years and engine options. A 1970 Charger R/T with a 440 Magnum produced 375 horsepower, while a 2023 Charger with the supercharged 6.2-liter HEMI V8 produces 807 horsepower. The engine you have determines your power output more than anything else — two Chargers from the same year can differ by hundreds of horsepower depending on which engine was installed at the factory.
Finding your exact horsepower requires knowing your model year and engine size. You can locate this information on your vehicle identification number (VIN) — the 17-character code on your dashboard or driver's side door jamb — or in your owner's manual. Once you know your engine, you can match it to the horsepower table below.
Key Takeaways
- Dodge Charger horsepower ranges from around 250 hp in base models to 807 hp in the supercharged 2023 models, depending on engine choice.
- Your VIN and owner's manual contain the engine code needed to determine your exact horsepower rating.
- The same model year Charger can have vastly different power outputs — a 2020 Charger might have 370 hp or 485 hp depending on which V8 engine was ordered.
- Engine displacement, supercharging, and fuel octane requirements all affect the horsepower your specific Charger produces.
Classic Dodge Charger horsepower (1966–1974)
The original Charger generation produced horsepower figures that reflected the muscle car era. The 1970 Charger R/T with the 440 Magnum generated 375 horsepower, while the high-performance 426 Hemi produced 425 horsepower in the same year. Earlier models like the 1968 Charger with a 440 Magnum made 375 horsepower as well.
These figures were measured using the gross horsepower standard of the time, which differed from the net horsepower measurement used today. Gross horsepower was measured without engine accessories like the alternator and air conditioning compressor running, so the numbers were higher than what the engine actually delivered to the wheels. When the industry switched to net horsepower in 1972, the same engines showed lower numbers on paper even though their actual output had not changed.
Second-generation Charger horsepower (1975–1978)
Horsepower dropped significantly in the mid-1970s due to emissions regulations and the shift to net horsepower measurement. A 1975 Charger with the 400 cubic-inch V8 produced 185 net horsepower, while the 440 Magnum made 215 horsepower. By 1978, the 440 had been discontinued, and the largest engine available was the 400, which produced 190 horsepower.
This era marked a major decline in muscle car performance across the industry. Stricter emissions standards, lower fuel octane ratings, and the move away from high-compression engines all contributed to the reduced power figures. The Charger remained a recognizable nameplate, but it no longer competed in the high-horsepower segment.
Modern Dodge Charger horsepower (2006–2023)
Dodge revived the Charger nameplate in 2006 with a modern four-door sedan design. The base model came with a 2.7-liter V6 producing 190 horsepower, while the 5.7-liter HEMI V8 generated 370 horsepower. By 2015, the HEMI had been upgraded to 370 horsepower across the lineup, and a supercharged 6.2-liter HEMI option called the Hellcat arrived, producing 707 horsepower.
The 2023 model year introduced the final generation before production ended, with the supercharged 6.2-liter HEMI producing 807 horsepower — the highest output Dodge ever put in a Charger. Standard models used the 5.7-liter HEMI at 370 horsepower. The Charger SRT Hellcat Redeye, the most powerful variant, delivered the full 807 horsepower to the rear wheels.
How to find your Charger's exact horsepower
Your VIN contains an engine code in the eighth position that tells you which engine your Charger has. For example, a "P" in that position on a 2015 Charger indicates a 5.7-liter HEMI, while an "L" indicates the supercharged 6.2-liter Hellcat engine. Once you identify your engine code, you can cross-reference it with Dodge's official specifications or your owner's manual to find the exact horsepower.
Your owner's manual also lists horsepower directly in the specifications section, usually near the front or back of the document. If you no longer have the manual, you can read a PDF version from Dodge's website by entering your VIN, or you can contact a Dodge dealership with your VIN and they will provide the specifications. The dealership approach takes longer but guarantees accuracy.
Why horsepower varies between model years
Dodge adjusted Charger horsepower across generations for several reasons. Emissions regulations required manufacturers to reduce nitrogen oxide and particulate emissions, which often meant lower compression ratios and less aggressive engine tuning. Fuel octane availability also changed — older Chargers were designed for 100-octane fuel, while modern engines run on 87-octane regular unleaded, which affects maximum power output.
Technological improvements like direct fuel injection, variable valve timing, and turbocharging allowed modern engines to produce more horsepower while meeting stricter emissions standards. A 2023 Charger's 807 horsepower from 6.2 liters is substantially more efficient than a 1970 Charger's 425 horsepower from a 426 cubic-inch engine, even though the displacement is similar. Modern engine management systems optimize combustion in ways that were impossible in the muscle car era.
Engine options and their horsepower across Charger generations
| Model Year Range | Engine Option | Displacement | Horsepower |
|---|---|---|---|
| 1970–1971 | 440 Magnum | 440 cu in | 375 hp |
| 1970–1971 | 426 Hemi | 426 cu in | 425 hp |
| 1975–1978 | 400 | 400 cu in | 185–190 hp |
| 1975–1978 | 440 | 440 cu in | 215 hp |
| 2006–2010 | 2.7L V6 | 2.7L | 190 hp |
| 2006–2023 | 5.7L HEMI V8 | 5.7L | 370 hp |
| 2015–2023 | 6.2L Supercharged HEMI | 6.2L | 707–807 hp |
Frequently Asked Questions
How do I know if my Charger is a Hellcat?
Hellcat models have a distinctive supercharger whine when the engine starts and a badge on the hood or trunk that says "Hellcat." The 6.2-liter supercharged engine produces either 707 horsepower (2015–2022) or 807 horsepower (2023), compared to 370 horsepower for the standard 5.7-liter HEMI. Your owner's manual or VIN will confirm the engine type if you are unsure.
Does a 2012 Charger have more horsepower than a 2008 Charger?
Both the 2012 and 2008 Chargers with the 5.7-liter HEMI produce 370 horsepower. The base V6 models produce 190 horsepower in both years. Horsepower remained consistent across these model years unless you compare different engine options — a 2012 Charger with a HEMI has the same power as a 2008 with a HEMI.
What is the difference between gross and net horsepower?
Gross horsepower was measured with the engine running alone, without accessories like the alternator and air conditioning compressor. Net horsepower includes those accessories running, so it is a more realistic measure of power available to move the car. Dodge switched to net horsepower in 1972, which is why 1970 Chargers appear more powerful on paper than they actually were compared to modern standards.
Can I increase my Charger's horsepower with modifications?
Yes, but the amount depends on your engine and the modifications. A standard 5.7-liter HEMI can gain 20–50 horsepower with a cold air intake and exhaust upgrade. Supercharger kits can add 100+ horsepower to naturally aspirated engines. Consult a performance shop familiar with your model year to understand what is possible and what warranty implications exist.
Why does my 2020 Charger feel less powerful than the horsepower number suggests?
Horsepower is measured at the engine's crankshaft, not at the wheels. Automatic transmissions, the driveshaft, and the differential all consume power, so you lose roughly 15 percent of the engine's horsepower before it reaches the ground. A 370 hp Charger delivers approximately 315 hp to the rear wheels. Manual transmissions lose slightly less power, but the difference is small.
