Just when drivers thought that the heyday of muscles cars was long gone, Dodge introduced the 707-horsepower Challenger SRT Hellcat. The Challenger SRT Hellcat reignited car enthusiasts’ love for muscle so much that Dodge and SRT made something even more powerful, the Dodge Challenger SRT Demon. So how do the two stack up against each other? Is the Challenger SRT Demon really different than the Challenger SRT Hellcat? Let’s take a closer look at the two…


The Challenger SRT Demon and the Challenger SRT Hellcat dominate the road, but in a race, there is an obvious winner. In 2018, the Dodge Challenger SRT Demon took the title from the Dodge Challenger SRT Hellcat as the fastest and most powerful production car on the street. The Challenger SRT Demon produces up to 840 horsepower and 700 lb-ft of torque. Due to the engine’s power and the Challenger SRT Demon’s race-inspired design, the Challenger SRT Demon blows through a quarter-mile in 9.6 seconds and can accelerate from 0-60 mph in 2.3 seconds.

The Challenger SRT Hellcat produces 707 horsepower and 650 lb-ft of torque, which is more than the Chevy Camaro and the Ford Mustang, but it’s 0-60 mph acceleration time of 3.5 seconds and quarter-mile time of 11.2 seconds is not enough to beat the Challenger SRT Demon in a race.


Now for the real question, what makes their engines different? That’s not an easy question to answer without getting very technical. Dodge and SRT went to serious lengths to make an engine that can produce all of that power and though both engines may sound similar, the Challenger SRT Demon has a lot more components.

The Challenger SRT Hellcat has a supercharged 6.2-liter HEMI SRT Hellcat V8 engine. The SRT Hellcat engine has a 2.4-liter supercharger, one fuel pump and a heat-treated aluminum-alloy cylinder heads, die-cast aluminum rocker covers and a forged-steel crankshaft. The SRT Hellcat engine also has a boost pressure of 11.6 psi.

The Challenger SRT Demon takes that engine configuration a step further. The SRT Demon engine is a supercharged 6.2-liter HEMI Demon V8 engine and the supercharger on the SRT Demon engine is .3 liters bigger (2.7L) bigger than the SRT Hellcat, and instead of one fuel pump, the SRT Demon engine has two dual-stage fuel pumps. Additionally, the Challenger SRT Demon has 25 other engine components that the SRT Hellcat engine doesn’t have. Of the 25 additional engine components, the Air Grabber hood and the SRT Power Chiller are two of the most notable because they provide significant horsepower gains by increasing the amount of cold air the engine receives.


The Challenger Demon has a wider body than the standard Challenger SRT Hellcat, however, Dodge did release a new Challenger SRT Hellcat Widebody for the 2018 model year. The Challenger SRT Demon was clearly built for the drag circuit as it comes standard with one seat, and it has a looser front suspension and huge drag radials. The Challenger SRT Hellcat was built for performance but also comfort. Built with seating for five passengers, the Challenger SRT Hellcat has a fierce look but maintains the functionality of a daily driver.

The Challenger SRT Demon comes equipped with 18×11-inch lightweight aluminum wheels with Demon-branded Nitto drag radial tires to give that extra boost of speed. The Challenger SRT Hellcat comes with 20×9.5-inch SRT low gloss black perf wheels with all-season performance tires.

Both vehicles will have a variety of trims and colors.
