Pro Tip: Pay close attention to fender badges and specific styling cues. Redeye models often feature a dual-snorkel hood and Redeye logos, while the Demon has unique Widebody flares and Demon-specific badging.
Step 3: Consulting Official Manufacturer Resources
What you need: Internet access and a few minutes of time.
Instructions: The most reliable source for a Hellcat’s horsepower is the manufacturer itself. Navigate to the official Dodge website (www.dodge.com). Look for sections like “Current Vehicles,” “Build & Price,” or “Specifications.” Once you locate the Challenger or Charger models, you can typically select the specific SRT Hellcat trim and view its detailed specifications, including engine output. The website will clearly list the horsepower and torque figures for each variant, often broken down by model year. This method provides the exact, officially published crank horsepower directly from the source.
Pro Tip: Always prioritize the manufacturer’s official website over third-party sites or forums, as this ensures the information is current and accurate, reflecting any minor updates or changes made during a model year.
Step 4: Cross-Referencing with Reputable Automotive Publications
What you need: Internet access and a critical eye for credible information sources.
Instructions: After consulting the official Dodge website, cross-reference this information with well-established and respected automotive publications. Websites like MotorTrend (www.motortrend.com), Car and Driver (www.caranddriver.com), and Edmunds (www.edmunds.com) consistently review and publish detailed specifications for new vehicles, including specific horsepower figures. Use their search functions to look for “Dodge Challenger Hellcat horsepower [model year]” or “Dodge Charger Hellcat Redeye specifications.” These sources not only confirm manufacturer claims but often provide real-world test results and comparisons, adding depth to your understanding.
Pro Tip: Be selective about your sources. Avoid forums, unverified blogs, or social media posts as primary information providers. Stick to professional automotive journalists and established review sites that have a proven track record of accuracy and unbiased reporting.
Step 5: Understanding Model Year Evolution
What you need: An awareness that vehicle specifications can change over time.
Instructions: The horsepower of a “Hellcat” isn’t a static number across all years. As noted in Step 1, the base Hellcat saw an increase from 707 hp to 717 hp starting in the 2019 model year. New variants like the Redeye (797 hp) were introduced in 2019, the Super Stock (807 hp) in 2020, and the Demon was a singular 2018 model. When researching, always specify the exact model year to ensure you’re getting the correct horsepower figure for that particular vehicle. For example, a “2016 Challenger Hellcat” will have different stated horsepower than a “2020 Challenger Hellcat Redeye.” This attention to detail is critical for accurate identification.
Pro Tip: When discussing or comparing Hellcat horsepower, always include the model year (e.g., “a 2017 Hellcat” or “a 2021 Hellcat Redeye”). This precision eliminates ambiguity and ensures everyone understands exactly which variant and its corresponding power output is being referenced.
Step 6: The Fuel Factor: How Octane Affects Stated Power
What you need: Basic knowledge of automotive fuels and their octane ratings.
Instructions: For optimal performance and to achieve the stated horsepower figures, all Hellcat models require premium unleaded gasoline with an octane rating of 91 or higher. The engine’s computer (ECU) is tuned to take advantage of higher octane fuel, which resists pre-ignition (knock) under high compression and supercharger boost. Using lower octane fuel can cause the ECU to retard ignition timing to protect the engine, resulting in a noticeable decrease in horsepower and potential long-term damage. For the Challenger SRT Demon, achieving its full 840 hp specifically requires 100+ octane race fuel (via the Demon Crate’s performance PCM), whereas it produces 808 hp on 91/93 octane pump gas.
Pro Tip: Always adhere strictly to the fuel recommendations found in your vehicle’s owner’s manual. While a Hellcat might run on lower octane fuel, it will not produce its maximum stated horsepower and could experience increased wear or long-term engine issues.
Step 7: Distinguishing Crank Horsepower vs. Wheel Horsepower
What you need: An understanding of how horsepower is measured and reported.
Instructions: It’s important to differentiate between “crank horsepower” (bhp – brake horsepower) and “wheel horsepower” (whp). The horsepower figures quoted by Dodge (707, 717, 797, 807, 808, 840 hp) are all crank horsepower measurements, taken directly at the engine’s crankshaft without any drivetrain components attached. When this power is transmitted through the transmission, driveshaft, differential, and axles to the wheels, some energy is inevitably lost due to friction and parasitic drag. This typically results in a 10-15% loss, meaning the horsepower measured at the wheels (whp) will be lower than the stated crank horsepower. For example, a 717 hp Hellcat might put down approximately 600-650 whp on a dynamometer.
Pro Tip: Never directly compare published crank horsepower figures to dyno-measured wheel horsepower numbers. These are two distinct measurements, and confusing them can lead to misunderstandings about a vehicle’s true performance capabilities.
Step 8: Verifying with Your Vehicle’s Documentation
What you need: Your vehicle’s owner’s manual or the Vehicle Identification Number (VIN).
Instructions: If you own a Hellcat, the most definitive source for its specific stock horsepower rating is its own documentation. Consult the owner’s manual, typically found in the glove compartment, under the “Specifications” or “Engine” section. This will provide the precise factory-rated horsepower for your exact model and year. Alternatively, you can use your car’s VIN (Vehicle Identification Number) to look up detailed factory specifications. While some online VIN decoders might offer engine details, for specific horsepower figures, the owner’s manual or contacting a Dodge dealership with your VIN will yield the most accurate results for your individual vehicle.
Pro Tip: Keep your owner’s manual safe and accessible. It’s an invaluable resource for all your vehicle’s specifications, maintenance schedules, and operational details, providing certainty beyond internet searches.

Key Factors Influencing Hellcat Performance
While the advertised horsepower figures are impressive, a Hellcat’s real-world performance can be influenced by several external and internal factors. Understanding these can help you maximize your beast’s potential.
Fuel, Temperature, and Altitude: The Performance Triangle
The environment and what you feed your Hellcat play a significant role in how much power it truly puts down.
- Fuel Quality: All Hellcats are designed to run on premium 91+ octane fuel. Using lower octane fuel can lead to the engine’s computer retarding timing to prevent detonation, which directly reduces horsepower and torque. Always use the recommended fuel for optimal performance.
- Ambient Temperature: Supercharged engines love cool air. Colder, denser air contains more oxygen, allowing the engine to make more power. Conversely, hot weather can cause performance to drop slightly as the engine works harder to cool the incoming air charge. This is why a Hellcat might feel even more powerful on a crisp, cool evening.
- Altitude: Thinner air at higher altitudes means less oxygen available for combustion. While a supercharger helps force air into the engine, it still can’t completely overcome the effects of very high altitudes, which can lead to a slight reduction in overall power compared to sea level.
For peak performance, try to run your Hellcat in cooler conditions with a tank full of fresh, high-octane fuel.
Maintenance, Modifications, and Driver Skill
Beyond environmental factors, how you care for and drive your Hellcat also impacts its performance.
- Regular Maintenance: Keeping up with routine maintenance, such as oil changes, spark plug replacements, and air filter checks, ensures your engine runs efficiently and produces its advertised power consistently. A neglected engine won’t perform its best.
- Aftermarket Modifications: Many Hellcat owners choose to modify their vehicles for even more power. Common upgrades include cold air intakes, smaller supercharger pulleys (to increase boost), and custom engine tunes. However, it’s crucial to choose reputable tuners and quality parts, as improper modifications can damage the engine or even reduce reliability.
- Driver Skill: Horsepower is only one part of the equation. Effectively launching a Hellcat and managing its immense power requires considerable driver skill. Getting the tires to hook up, managing traction control, and knowing how to utilize the car’s various drive modes (e.g., Track mode) are critical for putting all that power to the pavement efficiently and safely.
A well-maintained Hellcat in the hands of a skilled driver will always outperform one that isn’t, regardless of its peak horsepower figure.
