The Challenger SRT Demon 170: The King of the Quarter Mile
When Dodge announced the “Last Call” series, a collection of special-edition Challengers marking the end of the iconic HEMI V8’s production run, few could have predicted the legendary status of the final entry. The Dodge Challenger SRT Demon 170 is not just a car; it is a statement, a final, defiant roar from the age of internal combustion. Born from the same lineage as the record-setting 2018 Demon, the 170 represents the zenith of Dodge’s engineering prowess, a machine meticulously crafted for one purpose: absolute dominance on the drag strip.
At the heart of this beast lies a modified version of the legendary 6.2-liter supercharged HEMI V8. While it retains the familiar displacement, the Demon 170 undergoes a radical transformation, incorporating a larger, more aggressive 3.0-liter supercharger. This monstrous forced-induction system, coupled with a suite of upgraded internal components, allows the engine to breathe deeper and spin faster than ever before. The result is a powertrain that defies belief, capable of unleashing a staggering 1,025 horsepower and 945 lb-ft of torque when fed with E85 ethanol. Even on premium pump gas, the Demon 170 commands a formidable 900 horsepower and 810 lb-ft of torque, numbers that dwarf those of its contemporaries.
The performance figures are nothing short of astronomical. On a prepared drag strip, the SRT Demon 170 rockets from 0 to 60 mph in a mind-bending 1.66 seconds, a time that rivals the world’s most exotic hypercars. Its quarter-mile time is equally astonishing, clocking in at a scarcely believable 8.91 seconds at over 151 mph. These aren’t just statistics; they are benchmarks that rewrite the record books.
To achieve such performance, Dodge engineers implemented a comprehensive suite of chassis and drivetrain modifications. The suspension has been recalibrated for maximum traction, featuring specialized drag-tuned components that work in harmony with the beefy drag radials. A new trans-brake system, honed through rigorous testing, allows for picture-perfect launches, while revised driveline components ensure that every ounce of power is efficiently transferred to the pavement.
Production of the Demon 170 was, by design, limited to a mere 3,000 units in the United States, making it one of the most exclusive muscle cars ever created. The exclusivity, combined with the unparalleled performance, commanded a premium price tag, with MSRPs starting north of $100,000. Yet, for the most dedicated enthusiasts and collectors, the Demon 170 represents the ultimate expression of American muscle, a rolling testament to an era that will forever be etched in automotive legend.
The Dodge Challenger SRT Demon: The Original Drag Strip Monster
Before the Demon 170 claimed the throne, there was the original legend: the 2018 Dodge Challenger SRT Demon. Unveiled with more fanfare than perhaps any muscle car before it, the Demon was engineered with a singular focus: to dominate the quarter mile. Dodge didn’t just build a fast car; they built a drag racing weapon disguised as a street-legal production vehicle, complete with a factory-installed Demon Crate containing a treasure trove of drag racing essentials.
The heart of the SRT Demon is a heavily modified version of the 6.2-liter supercharged HEMI V8, sharing its displacement with the Hellcat but boasting a host of upgrades that set it apart. A larger 2.7-liter supercharger spins at an awe-inspiring 14.5 psi, feeding the engine a steady diet of air. The engine block, crankshaft, connecting rods, and pistons were all strengthened to withstand the immense forces at play. The result is a powerplant capable of producing 840 horsepower and 770 lb-ft of torque on premium 100-octane race fuel. On regular 91-octane gasoline, the Demon still delivers a formidable 808 horsepower and 717 lb-ft of torque, figures that remain eye-watering even by today’s standards.
Dodge’s marketing campaigns for the Demon were as bold as the car itself. They proudly proclaimed that the National Hot Rod Association (NHRA) had banned the car for achieving a quarter-mile time of just 9.65 seconds at 140 mph, a feat that underscored its unparalleled drag strip dominance. While achieving such times required specialized equipment and preparation, independent testing confirmed the Demon’s extraordinary capabilities. With launch control engaged and the Demon Crate’s Drag Pack properly installed, drivers could witness 0-to-60 mph times dipping into the low 2-second range, a testament to the car’s explosive acceleration.
Beyond the engine, the Demon incorporated a suite of performance-enhancing features. The Air-Grabber hood, featuring the largest functional cold-air intake ever installed on a production car, ensured the engine received a constant supply of cool, dense air. Torque-limiting software optimized power delivery for drag racing scenarios, while the lightweight construction, achieved through the removal of features like the rear seats and even the carpet in some configurations, shaved precious pounds for maximum performance.
The limited production run of 3,300 units ensured the SRT Demon’s exclusivity, solidifying its status as a collector’s item. While its quarter-mile times may have been surpassed by its successor, the 2018 Demon remains a cultural phenomenon, a symbol of American automotive excess and a benchmark for drag-focused performance that may never be replicated.
