If you know about the Hellcat engine at all, you know it started with the 2015 Dodge Challenger SRT Hellcat. What’s cool about this particular car is that it looks a lot like muscle cars of yesterday, but it comes fully loaded with all the modern amenities we’ve grown accustomed to. The Challenger Hellcat sports the 707 horsepower 6.2-liter Hellcat V8 engine, which immediately puts it atop the muscle category and even made other American car companies consider adding more power.
However, the Challenger SRT Hellcat wasn’t the last Challenger to get the upgrade. In 2022, Dodge put out the Challenger Hellcat Jailbreak, which pushed the engine even further, upgrading to a 797 horsepower V8. But perhaps the king of all Challengers was the 2018 Dodge Challenger SRT Demon. The Demon took the Challenger to a whole new level with its 840 horsepower and 770 lb-ft of torque. The only problem? You’ll need to power it with 100 octane fuel to hit those levels of horsepower, and last time we checked, that wasn’t available at the corner gas station.
