The “Hellcat” is a high-performance version of the Dodge Challenger and Charger models that have been in production since 2015. The Hellcat is known for its massive horsepower output, and there have been several variants of the car with varying levels of power. In this answer, I’ll provide an overview of the highest horsepower Hellcat models.
The first Hellcat models were introduced for the 2015 model year and were equipped with a supercharged 6.2-liter Hemi V8 engine that produced 707 horsepower and 650 lb-ft of torque. This engine was paired with either a six-speed manual or eight-speed automatic transmission.
In 2017, Dodge introduced the Challenger SRT Demon, which was a limited-edition model designed for drag racing. The Demon was equipped with a modified version of the Hellcat’s supercharged 6.2-liter Hemi V8 engine that produced a whopping 808 horsepower and 717 lb-ft of torque when running on high-octane racing fuel. The Demon was capable of running the quarter-mile in under 10 seconds and had a top speed of 168 mph.
For the 2018 model year, Dodge introduced the Challenger SRT Hellcat Widebody, which was a version of the Hellcat that had wider fenders to accommodate wider tires for improved traction. The Hellcat Widebody was equipped with the same supercharged 6.2-liter Hemi V8 engine as the regular Hellcat, but it produced slightly more power at 707 horsepower and 717 lb-ft of torque. The Hellcat Widebody was also available with either a six-speed manual or eight-speed automatic transmission.
In 2019, Dodge introduced the Challenger SRT Hellcat Redeye, which was an even more powerful version of the Hellcat. The Hellcat Redeye was equipped with a supercharged 6.2-liter Hemi V8 engine that produced 797 horsepower and 707 lb-ft of torque. This engine was paired with an eight-speed automatic transmission. The Hellcat Redeye was capable of reaching a top speed of 203 mph and could run the quarter-mile in 10.8 seconds.
In 2020, Dodge introduced the Charger SRT Hellcat Redeye, which was essentially the same car as the Challenger Hellcat Redeye, but with a four-door sedan body style. The Charger Hellcat Redeye was equipped with the same supercharged 6.2-liter Hemi V8 engine as the Challenger Hellcat Redeye, producing 797 horsepower and 707 lb-ft of torque. The Charger Hellcat Redeye could reach a top speed of 203 mph and could run the quarter-mile in 10.6 seconds.
Finally, in 2021, Dodge introduced the Challenger SRT Super Stock, which is the most powerful version of the Hellcat to date. The Super Stock is equipped with a supercharged 6.2-liter Hemi V8 engine that produces 807 horsepower and 707 lb-ft of torque. This engine is paired with an eight-speed automatic transmission. The Super Stock is capable of reaching a top speed of 168 mph and can run the quarter-mile in 10.5 seconds.
In conclusion, the highest horsepower Hellcat models are the Challenger SRT Demon and the Challenger SRT Super Stock, both of which produce 807 horsepower. The Hellcat Redeye models produce slightly less power at 797 horsepower, while the regular Hellcat and Hellcat Widebody models produce 707 horsepower.
