Hennessey unleashes the 1700 demon: 1.355 hp and a thunderous roar
The Automotive world has seen its share of outlandish claims, but Hennessey Performance’s new Demon 1700 isn’t just a statement – it’s a full-blown acceleration weapon. Boasting a staggering 1,700 horsepower, this beast is poised to dominate both drag strips and public roads, cementing Texas’s reputation for relentlessly pushing the boundaries of Automotive performance.
A radical redesign
Starting with the legendary Dodge Challenger SRT Demon 170, Hennessey recognized the need for a significant upgrade. They’ve effectively rebuilt the engine from the ground up, ditching the factory 3.0-liter supercharger in favor of a more efficient dual-turbo setup. This surgical intervention has unleashed a monstrous 7.2-liter HEMI V8, stroked out to a massive 440 cubic inches – a nod to the era of legendary ‘Big Block’ muscle cars.
The engine itself has been completely forged, built to withstand the brutal 23 psi generated by twin Precision PT6870 turbochargers. This configuration allows the car to breathe with unprecedented violence, translating to a dyno-verified 1,355 horsepower directly to the rear wheels – a figure that dwarfs the output of a Bugatti Chiron.
Exclusive numbers and a new chapter
To handle this immense power, Hennessey has implemented a bespoke fuel system utilizing E85 and reinforced Stage 3 transmission. It’s not just about brute force; the Demon 1700 represents the debut of Hennessey Special Operations (HSO), a division dedicated to ultra-low-volume projects with stratospheric performance. Only twelve units will ever be produced, making it one of the most exclusive vehicles on the planet.
Completing the quarter-mile in a blistering 7.9 seconds at over 280 mph is a testament to the spirit of Automotive freedom – a defiant roar against the encroaching tide of electrification. While the industry embraces silence, Hennessey delivers a symphony of stainless steel exhaust notes and burning rubber. Price: $200,000+
Tim Kuniskis, head of Dodge and RAM, was reportedly stunned by the engine's performance, witnessing the 7.2-biturbo devour air and generate 675 horsepower more than the most extreme factory Demon configuration.
Possessing one of these twelve vehicles demands more than just a substantial bank account; it requires the courage to tame a machine constantly seeking to shatter traction limits, even at highway speeds. This isn’t just a muscle car; it’s a declaration of intent – a final, deafening statement from the V8 engine before it fades into Automotive history.
