It’s Here: The 2021 Dodge Charger SRT Hellcat Redeye:

797 Horsepower On Tap Making It The Fastest Four-Door Muscle Car...

It’s been two long years since the 797 horsepower Dodge Challenger SRT Hellcat Redeye made its debut. At its launch, Charger enthusiasts were frustrated with the performance brand for only giving the Challenger the same powerplant that was found under the hood of the 2018 Dodge Challenger SRT Demon. Well, a new day has come and the Dodge//SRT brand has been listening. Enter the 2021 Dodge Charger SRT Hellcat Redeye Widebody, the most powerful sedan and fastest mass-produced sedan in the world.

Just like its sibling the Charger SRT Hellcat, the Charger SRT Hellcat Redeye will come standard with Dodge’s widebody exterior featuring integrated fender flares that add 3.5-inches of body width. This means that larger 20-inch by 11-inch Lightweight Carbon Black wheels wrapped in Pirelli 305/35ZR20 tires will attempt to help to put the near 800 horsepower of output to the ground.

While the exterior of the 2021 Dodge Charger SRT Hellcat Redeye looks like the standard Hellcat model, there is a lot of differences under the skin. Starting with supercharged 6.2-liter HEMI® high-output V-8 from the Demon which delivers 797 horsepower and 707 lb.-ft. of torque, the Charger SRT Hellcat Redeye screams. Only available with the TorqueFlite 8HP90 8-speed automatic transmission provides optimized fuel economy while enabling maximum performance with 160-millisecond shifts, and rev-matching.

Internal changes to the transmission in the Charger SRT Hellcat Redeye include an upgraded torque converter. The Charger Redeye’s torque converter delivers an 18% increase in torque multiplication when compared with the standard Charger SRT Hellcat.
Like its Demon brethren, the Charger SRT Hellcat Redeye’s engine has 25 major component upgrades, including a larger supercharger, strengthened connecting rods and pistons, high-speed valvetrain, fuel injection system, and improved lubrication system. Compared to the standard SRT Hellcat, the Redeye engine features…

  • Largest Factory Supercharger Of Any Production Car – 2.7-liters Compare To Hellcat’s 2.4-liters
  • Increased Boost Pressure: 14.5 PSI Compared To 11.6 PSI
  • Higher RPM Limited: 6,500 RPM VS 6,200 RPM
  • Fuel Pumps: Two Dual-Stage Fuel Pumps VS One
  • Larger Induction Airbox With Three Sources Of Intake Air –
    • Functional, New SRT Performance Hood
    • Mail-Slot Grille Opening
    • Airbox Opening Near The Wheel Liner

When at full throttle, the 2021 Dodge Charger SRT Hellcat Redeye consumes 1.43 gal/min (5.4 liters/min) of fuel. That’s enough to drain the fuel tank in just under 11 minutes, yet the car is still rated at 22 miles per gallon (mpg) when driven in normal highway conditions. Now, that’s impressive.

There is also other powertrain tech from the Challenger SRT Demon that helps the Charger SRT Hellcat Redeye earn the title as the most-powerful four-door muscle car…

  • Torque Reserve Delivers Up To 3.9 PSI Of Boost At Launch and Up To 55% More Engine Torque
  • Only Factory Production Sedan With Both SRT Power Chiller™ and After-Run Chiller
  • High-Strength Steel Prop Shafts Provide A 15% Increase In Torque Capacity
  • 41-Spline Half-Shafts Provide A 20% Increase In Torque Capacity

A newly designed, functional performance hood on both Charger SRT Hellcat Redeye and Hellcat models not only looks more sinister but provides maximum air intake to the supercharged HEMI from the functional hood scoop to boost power. This hood takes full advantage of the SRT Hellcat Redeye’s air intake system and is sealed to the airbox. The new performance hood, mail-slot grille opening, and airbox opening near the wheel liner combine to give the high-output engine an 18% greater air-flow rate than the 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 one second.

The innovative, award-winning SRT Power Chiller™, standard on the Charger SRT Hellcat Redeye only, lowers the intake air temperature further, resulting in improved performance. It diverts the air-conditioning refrigerant from the 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.

Race Cooldown, also an industry first, minimizes any heat soak effects, allowing the engine to stay in optimum operating temperature. When the engine shuts down, the Race Cooldown feature 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. Race Cooldown was first featured on the Challenger SRT Demon in 2018 and became standard on the Charger SRT Hellcat in 2019.

The 2021 Dodge Charger SRT Hellcat Redeye can run the quarter-mile in 10.6-seconds @ 129 mph (that is 0.36-seconds and 4 mph faster than the Charger SRT Hellcat. The top speed of the Charger SRT Hellcat Redeye is also 7 mph faster than the standard Hellcat at 203 mph. But when it comes to the track, the Charger SRT Hellcat Redeye ran a 1.2-second faster lap around FCA’s 2.1-mile road course (or about 7 car lengths) than the Charger SRT Hellcat.

Those colors include F8 Green, Frostbite, Go Mango, Granite Crystal, Hellraisin, IndiGo Blue, Octane Red, Pitch Black, Sinamon Stick, Smoke Show, TorRed, Triple Nickel, and White Knuckle.

The Satin Black Appearance Package, adds a hand-painted Satin Black hood, roof, decklid, and spoiler, enhancing the Charger’s sinister look.
