Dodge’s 797-Horsepower 2019 Challenger SRT HELLCAT Redeye:

A Deeper Look Into Dodge's Baby Demon:

With Ford Motor Company boasting about it’s upcoming 2019 Ford Mustang GT500 having over 700 horsepower, Dodge wasn’t going to let it spoil the fun for the 2019 model year. Using the 2018 Dodge Challenger SRT Demon as a template for improving the SRT HELLCAT, Dodge managed to build another “Top Cat” to fill in the slot left by the quarter-mile king it built for only one model year.

Dodge introduced the 2019 Dodge Challenger SRT HELLCAT Redeye, a 797-horsepower and 707 lb.-ft. of torque  muscle car that ups the ante for the Dodge muscle car lineup. Taking the 6.2-liter Supercharged HEMI V8 from the SRT Demon, the HELLCAT Redeye gets unique tuning for this application, without losing much horsepower. The SRT Demon had 808-horsepower in it’s standard form, while the the SRT HELLCAT Redeye is only 11-horsepower down from it’s big brother.

Unlike the SRT Demon, the SRT HELLCAT Redeye gets some options. The amazing powertrain can be equipped in either standard Challenger SRT HELLCAT body or optioned with the widebody kit. For those not on a suicide option, may want to pay for the widebody kit, which takes advantage of the Pirelli  305/35ZR20 All-season versus the Pirelli (PZero Nero All-season) 275/40ZR20 tires on the non-widebody cars. The SRT HELLCAT Redeye offers two final drive ratios, a standard 2.62:1 or available 3.09:1 for enhanced launch capability.

At full throttle, the Dodge Challenger SRT HELLCAT Redeye’s high-output engine consumes 1.43 gal/min (5.4 liters/min) of fuel – enough to drain the fuel tank in just under 11 minutes, yet is still rated at 22 miles per gallon (mpg) when driven in normal highway conditions.

The 2019 Challenger SRT HELLCAT lineup delivers improved performance numbers, including a new top speed of 203 miles per hours (mph), making the Challenger SRT HELLCAT Redeye the most powerful, quickest and fastest muscle car.

Challenger SRT Models 1/4-mile elapsed time/speed Top Speed
Redeye Widebody 10.8 seconds @ 131 mph 203 mph
HELLCAT Widebody 10.9 seconds @ 127 mph 195 mph
Redeye 11.1 seconds @ 131 mph 203 mph
HELLCAT 11.2 seconds @ 125 mph 199 mph




Additional features from the SRT Demon that help the Challenger SRT HELLCAT Redeye achieve its status as the most powerful, quickest and fastest muscle car:

  • Torque Reserve delivers up to 3.9 psi of boost at launch and up to 55 percent more engine torque
  • Only factory production car with both SRT Power Chiller™ and After-Run Chiller
  • High-strength steel prop shafts provide a 15 percent increase in torque capacity
  • 41-spline half shafts provide a 20 percent increase in torque capacity

One key to the engine’s imposing power output is air – and plenty of it. The new, low-restriction, dual snorkel hood is fully functional and sealed to the air box.

When combined with the Air Catcher headlamp and an inlet near the wheel liner, these three sources give the SRT HELLCAT Redeye’s high-output engine an 18 percent greater air-flow rate than last year’s SRT HELLCAT engine (1,134 cubic feet per minute). At full power, this is the equivalent flow rate to 89 adults simultaneously emptying their lungs in 1 second.

The revised air inlet path on the new dual snorkel hood results in an intake air temperature reduction of 4 degrees Fahrenheit.

The innovative, award-winning SRT Power Chiller™, standard on the Challenger SRT HELLCAT Redeye only, diverts the air-conditioning refrigerant from the interior cabin to a chiller unit mounted by the low-temperature circuit coolant pump. Charge air coolant, after being cooled by ambient air passing through a low-temperature radiator at the front of the vehicle, flows through the chiller unit, where it is further cooled. The chilled coolant then flows to the heat exchangers in the supercharger.

The SRT Power Chiller™ lowers the intake air temperature further on the Challenger SRT HELLCAT Redeye, resulting in improved performance.

The After-Run Chiller, also an industry first, minimizes any heat soak effects, allowing the engine to stay in optimum operating temperature. When the engine shuts down, the After-Run Chiller, now standard across the Challenger SRT HELLCAT model lineup in 2019, keeps the engine’s cooling fan and low-temperature circuit coolant pump running to lower the supercharger/charge air cooler temperature. The driver can track the supercharger coolant temperature on the SRT Performance Pages in the 8.4-inch Uconnect touchscreen and know in real time when the supercharger is at the optimum temperature for another run.

The 2019 Dodge Challenger SRT HELLCAT Redeye is available in fourteen different colors… B5 Blue, Destroyer Grey, F8 Green, Go ManGO, Granite Crystal, IndiGO Blue, Maximum Steel, Octane Red, Pitch Black, Plum Crazy, TorRed, White Knuckle and Yellow Jacket all return for 2019. A new color called Triple Nickel joins the color palette for 2019.
