What Challenger model has the most horsepower?

The top horsepower among Challenger models is held by the 2018 Dodge Challenger SRT Demon, delivering 808 horsepower on SAE net ratings (840 horsepower with 100-octane race fuel). It was produced in a limited run of 3,300 units, making it the standout in the lineup.

Where the horsepower race stands

To understand the current hierarchy, it helps to compare the top-tier Challengers that sports fans and buyers could actually encounter on the road or at the track.

Below is a concise look at the most powerful Challenger variants and their official horsepower ratings as published by Dodge.

• Dodge Challenger SRT Demon — 808 horsepower SAE net from a 6.2-liter supercharged Hemi; up to 840 horsepower on 100-octane race fuel; limited to 3,300 units produced in 2018.


• Dodge Challenger SRT Hellcat Redeye Widebody — 797 horsepower SAE net from the same engine with higher boost; available across several model years in the late 2010s to early 2020s.


• Dodge Challenger SRT Hellcat — 707 horsepower SAE net from the standard Hellcat variant.

In short, the Demon remains the horsepower king among Challengers, with the Hellcat Redeye Widebody a close second. No later Challenger model has surpassed the Demon's official horsepower rating.

How horsepower is measured and why the numbers matter

horsepower figures cited by Dodge use SAE net horsepower, which is measured at the crank with the engine in stock configuration, accessories installed, and aimed at real-world drivability. The Demon’s 840 horsepower figure refers to using 100-octane race fuel, a setup not typical for everyday driving, whereas the 808 horsepower rating reflects standard pump-gas performance. Because of fuel type, altitude, and testing methods, the numbers can vary between ratings and readers should treat them as published benchmarks rather than direct wheels horsepower.

Production context and current status

The Dodge Challenger as a model line was discontinued after the 2023 model year, ending an era that included the high-horsepower Hellcat and Demon variants. While new trims may come and go, no Challenger model released after the Demon has exceeded its horsepower milestone.

Summary

The 2018 Dodge Challenger SRT Demon is the most powerful Challenger ever built, with 808 horsepower SAE net (840 hp on 100-octane race fuel). The next strongest, the Hellcat Redeye Widebody, delivers about 797 hp, followed by the standard Hellcat at 707 hp. Since production ended in 2023, no Challenger model has surpassed the Demon's horsepower figure.

Which is faster, SRT or RT?

SRT is faster than RT because SRT models have more powerful engines, more horsepower, and better performance features. For example, a Challenger SRT has a more powerful engine with 475 horsepower compared to the 375 horsepower of the Challenger RT. This translates to quicker acceleration, with an SRT model achieving 0 to 60 mph in 3.7 seconds, while the RT model takes 4.3 seconds.
 
SRT

• Higher horsepower: SRT models typically have larger and more powerful engines, such as a 6.4L V8, producing around 475 horsepower and 470 lb-ft of torque. 
• Quicker acceleration: The combination of more power results in faster acceleration, with some models reaching 0-60 mph in around 3.7 seconds. 
• Advanced performance features: SRT models come with performance-oriented features, including a sport-tuned suspension and other technology, according to Bomnin Chrysler Dodge Jeep Ram Doral and Reddit users. 

RT

• Lower horsepower: RT models have a smaller engine, such as the 5.7L V8, that produces around 370-375 horsepower. 
• Slower acceleration: The RT's acceleration is still quick, but it is slower than the SRT. For example, the 0-60 mph time is around 4.3-5 seconds. 
• More affordable: RT models are often more budget-friendly and offer a balance between performance and practicality. 

Ultimately, the SRT is the faster and more performance-oriented option, while the RT is a more affordable and practical choice for drivers who want good performance without the highest price tag and fuel costs, notes Napleton's Northlake Chrysler Dodge Jeep Ram.

Which Challenger has the most HP?

The Dodge Challenger SRT Demon 170 has the most horsepower, producing up to 1,025 horsepower on an E85 ethanol blend. This makes it the most powerful production Dodge Challenger model ever made.
 

• Horsepower: Up to 1,025 hp when using E85 fuel; 900 hp on E10 fuel. 
• Engine: A heavily reworked 6.2-liter supercharged HEMI V8. 
• Performance: Capable of 0-60 mph in 1.66 seconds and a quarter-mile in 8.91 seconds. 
• Special features: The Demon 170's horsepower output is determined by the percentage of ethanol in the fuel.
