Dodge Charger Scat Pack Horsepower: What the Numbers Actually Mean

The Dodge Charger Scat Pack sits in an interesting spot in the muscle car lineup — powerful enough to feel genuinely fast, but positioned below the supercharged Hellcat variants. If you're researching this trim, the horsepower figure is probably the first thing you looked up. Here's what that number means, where it comes from, and how it compares across the Scat Pack's history.

The Core Horsepower Figure

The Dodge Charger Scat Pack is powered by the 6.4-liter HEMI V8, also known internally as the 392 HEMI (a nod to its approximate cubic-inch displacement). In standard production form, this engine produces 485 horsepower and 475 lb-ft of torque.

That output figure has remained consistent across most model years of the Scat Pack trim. It's a naturally aspirated engine — no turbocharger, no supercharger — which means the power comes entirely from displacement, compression, and mechanical efficiency rather than forced induction.

For context, the 392 HEMI sits above the base 5.7-liter HEMI (which makes around 370–375 hp depending on the model year and application) and well below the supercharged 6.2-liter Hellcat engine, which starts at 707 hp in standard Hellcat trim.

What the 392 HEMI Actually Is

The 6.4-liter HEMI is a pushrod V8 engine, a design lineage that traces back decades in American performance cars. Despite being a traditional overhead-valve architecture rather than a more modern overhead-cam design, it produces strong low-end and mid-range torque — the kind of power that's immediately noticeable in everyday driving, not just at high RPMs.

Key specs at a glance:

The 8-speed automatic transmission is standard on the Charger Scat Pack. Unlike the Challenger version of the Scat Pack, the Charger does not offer a manual transmission option — the four-door body style and its structural differences make that pairing unavailable.

How Scat Pack Horsepower Compares in the Charger Lineup 🏁

Understanding where the Scat Pack sits helps put the 485 hp number in context:

Note that Dodge introduced special editions and Jailbreak configuration options in later model years that allowed for different option combinations, though the core engine outputs remained tied to the specific engine offered.

Model Year Variations Worth Knowing

The Scat Pack trim was introduced to the Charger lineup in 2015, and the 485 hp output has been consistent across most production years through the 2023 model year — the final year of the current-generation Charger before Dodge transitioned to the next-generation platform.

A few things worth noting across model years:

• Early Scat Pack models (2015–2018) used a five-speed automatic before the eight-speed became standard
• Widebody variants were introduced around 2020, offering wider fender flares and broader wheel/tire fitment — the engine output remained the same
• Last Call editions in 2023 included special variants with unique styling packages, but engine specs were not meaningfully changed on the naturally aspirated Scat Pack

If you're comparing a used Scat Pack from 2016 to one from 2022, the horsepower rating is essentially the same — but features, transmission calibration, and available options differ.

Factors That Affect Real-World Performance

Advertised horsepower is a controlled measurement taken at the crankshaft under specific test conditions. What you experience at the wheels — and in actual driving — depends on several variables:

• Fuel quality: The 392 HEMI is rated for 91 octane premium fuel. Using lower octane can trigger knock sensors and reduce power output
• Altitude: Naturally aspirated engines lose power at higher elevations due to thinner air
• Temperature: Cold air is denser and generally helps combustion; very hot ambient temps can reduce effective output
• Condition and maintenance: Air filter health, spark plug condition, and oil viscosity all affect how efficiently the engine operates
• Modifications: Aftermarket cold-air intakes, exhaust systems, and tune files are common on Scat Pack owners who want more power — results vary widely and can affect warranty coverage

The Gap Between Specs and Your Situation

The 485 hp figure tells you what the engine is designed to produce under ideal conditions. Whether that output serves your needs depends on what you're buying the car for, where you'll drive it, how you'll maintain it, and what trim level and model year you're actually looking at.

Used Scat Pack pricing, insurance costs for a 485 hp rear-wheel-drive sedan, and fuel costs for a car that averages around 13–16 mpg city vary significantly depending on your location, driving record, and how you use the vehicle. Those numbers don't come from the spec sheet — they come from your own circumstances.
