When Dodge Went Full Mad Scientist
The Dodge Challenger has always been a big-engine muscle icon, but in 2023 Dodge flipped the whole script with the SRT Demon 170, a production car built explicitly to obliterate acceleration records. With more than 1,000 horsepower, it wasn’t just the fastest Challenger ever made. It became the most powerful street-legal muscle car on the planet, and a dramatic send-off for the HEMI V8 era as the Challenger’s final “Last Call” model.
A Brief Snapshot Of Challenger History
The Dodge Challenger name dates back to the early 1970s as Dodge’s pony car answer to the Mustang and Camaro. After decades of dedicated fans and several revivals, the modern Challenger was reborn in 2008 with retro styling and serious performance potential. Over time, Dodge kept pushing the envelope, especially with SRT variants like the Hellcat and earlier Demon models that raised the bar for American muscle.

What “Last Call” Means
Regulatory pressure and shifting market trends led Stellantis to announce the end of the Challenger and Charger in their current V8 forms after the 2023 model year. To celebrate, Dodge released a series of “Last Call” special editions, with each one celebrating a piece of the Challenger’s legacy. The Demon 170 was the final and most extreme, the ultimate muscle send-off.
The Birth Of Demon 170
Revealed at the Roadkill Nights Vegas performance festival in March 2023, the Challenger SRT Demon 170 built on the legacy of Dodge’s 2018 Demon but took things far beyond. Dodge engineers tore into almost every major system on the car, from the supercharger to the drivetrain, to create a vehicle unlike anything else sold by a mainstream manufacturer.
Engine: A Monster HEMI V8
At its heart is a supercharged 6.2-liter high-output HEMI V8 that produces 1,025 horsepower at 6,500 rpm and 945 lb-ft of torque at 4,200 rpm when fueled with high ethanol blends like E85. That makes it one of the most powerful production V8 engines ever offered—and the most powerful in muscle car history.

Boost And Breathing
The Demon 170’s supercharger is massive, featuring a 3.0-liter IHI unit with a 105mm throttle body and enlarged pulley that raises boost significantly above prior Hellcat and Demon models. The engine’s fueling system is designed to take full advantage of ethanol blends, allowing it to reach peak outputs that conventional gasoline simply can’t match.
Chassis And Strength
To harness all that power, Dodge upgraded nearly every section of the drivetrain. The differential housing is stronger, half shafts are beefed up, and the driveshaft is reinforced to handle the torque. Even Mickey Thompson drag-radials were developed specifically for the 170, making it the first factory car with staggered drag radials straight from the showroom.

Acceleration That Defies Belief
The Demon 170’s factory claims are staggering: 0–60 mph in just 1.66 seconds and a quarter-mile completed in 8.91 seconds at 151.17 mph, according to NHRA-certified testing. That makes it not just the fastest muscle car but one of the fastest production cars ever, irrespective of drivetrain type.

G-Force Launches And Physics Theater
Part of the Demon 170’s mind-bending performance comes from its launch physics. It can deliver over 2.0 Gs of acceleration at launch, meaning drivers feel twice their body weight pressing into the seat within fractions of a second. This level of force is more akin to rockets than road cars.
Quarter-Mile Dominance
Running an 8-second quarter-mile was once the exclusive domain of million-dollar specials or heavily modified racers. The Demon 170 did it straight from the factory, a feat that earned it an NHRA letter of violation on safety grounds because it ran faster than allowed without a roll cage or parachute. That’s how extreme this version truly is.
MSRP And Production
Despite its extreme performance, Dodge priced the SRT Demon 170 at a relatively modest $96,666 MSRP before fees and gas guzzler taxes, putting insane horsepower in the hands of enthusiasts rather than ultra-wealthy collectors. Production was limited, with around 3,300 units planned (3,000 for the US and 300 for Canada), making it both coveted and rare.

A New Kind Of Demon Heritage
The Demon 170 isn’t just about raw power. It incorporates second-generation drag racing tech like TransBrake 2.0, which helps drivers launch with precision, and drag-mode suspension tuning for maximum traction. This car wasn’t just built to boast figures; it was engineered to put them down on the strip.

Rarity And Collectibility
Because it marks the swan song of the Challenger’s gasoline era, the Demon 170 has already become a collector’s trophy. Early auction results and secondary market sales have shown examples trading in the $150,000–$250,000 range depending on mileage, color, and build number. Pitch Black models and other special colorways that rolled off the final assembly line are especially prized among Mopar enthusiasts, and command even higher premiums.

How It Compares To Other Challengers
Earlier Challengers like the Hellcat and first Demon were already mind-boggling. The Hellcat pushed over 700 horsepower, and the 2018 Demon nudged past 800, but those figures pale next to the Demon 170’s 1,025 horses. The Demon 170 is essentially the culmination of every line of Dodge performance thinking from the last decade.
The Legacy Of Muscle
In a world where electrification and emissions regulations are reshaping the industry, the Demon 170 represents the peak of internal combustion muscle car capability. Its performance numbers may hold up for years, especially since gas-powered muscle cars with this level of output are unlikely to become commonplace again anytime soon.
A Glorious Send-Off
The Challenger’s final production car refused to fade quietly. Instead, it exploded onto the scene with more horsepower and acceleration than nearly anything else on the road. More than just a farewell to a model, the Demon 170 was a statement that muscle cars could still be wild, extreme, and unapologetically fun even in a changing automotive landscape.
Final Thoughts
The Dodge Challenger SRT Demon 170 will be remembered as a muscle car myth made real—a factory-built monster that forced traditional performance metrics into a corner and rewrote them. It doesn’t just stand atop a list of horsepower figures. It symbolizes an era when muscle cars pushed boundaries and captured imaginations around the world.
