Dodge, America’s performance brand, continues to push the limits of the world’s only four-door muscle car, introducing the new 797-horsepower 2021 Dodge Charger SRT Hellcat Redeye — the most powerful sedan and fastest mass-produced sedan in the world.

To put that nearly 800 horsepower to the pavement, the new Charger SRT Hellcat Redeye boasts a Widebody exterior with integrated fender flares that add 3.5 inches of body width. The new 20-inch-by-11-inch Lightweight Carbon Black wheels ride on Pirelli 305/35ZR20 tires, which give the Charger SRT Hellcat Redeye more tire tread where the rubber meets the road. A newly designed, functional performance hood on both Charger SRT Hellcat models gives this four-door sedan an even more sinister look.

“The magic of the Dodge Charger is that it delivers all the performance of a true American muscle car while also being able to deliver a family of four or five, day in and day out,” said Tim Kuniskis, Global Head of Alfa Romeo and Head of Passenger Cars – Dodge, SRT, Chrysler and FIAT, FCA – North America. “The Charger is a big, comfortable, five-passenger sedan that can run the quarter-mile in the mid-10s, 0-60 in the mid 3s and reach a top speed of 203 mph, and be your daily driver.”

The Charger SRT Hellcat Redeye runs 1.2 seconds faster than the Charger SRT Hellcat on a 2.1-mile road course, equal to about 7 car lengths after one lap.

Dealer orders open for 2021 Dodge Charger models this fall, including the new SRT Hellcat Redeye; vehicles are scheduled to start arriving in dealerships in early 2021.

Dodge Charger Hellcat Redeye has the soul of the demon

Designed and engineered to appeal to muscle car enthusiasts who want even more — more power, more performance and more bragging rights at the drag strip — the heart of the new 2021 Dodge Charger SRT Hellcat Redeye comes from the limited-production 2018 Dodge Challenger SRT Demon. The supercharged 6.2-liter HEMI® high-output V-8 boasts 797 horsepower and 707 lb.-ft. of torque and is mated to a TorqueFlite 8HP90 eight-speed automatic transmission.

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 percent 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 valve train, fuel injection system and improved lubrication system.

Compared with the standard Charger SRT Hellcat engine, the Redeye features:

Largest factory supercharger of any production car – 2.7 liters versus 2.4 liters
Increased boost pressure: 14.5 psi versus 11.6 psi
Higher rpm limit: 6,500 rpm versus 6,200 rpm
Fuel: Two dual-stage fuel pumps versus one:
- At full throttle, the Dodge Charger SRT Hellcat Redeye 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
Larger induction air box with three sources of intake air:
- Functional, newly designed performance hood
- Mail-slot grille opening
- Air box opening near wheel liner

Additional features from the Challenger SRT Demon that help the Charger SRT Hellcat Redeye achieve its status as the most powerful four-door 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 sedan 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

Distinctive Dodge//SRT design: Where form meets the ultimate function

The Charger SRT Hellcat Redeye is unmistakably Dodge, featuring the aggressive, planted Widebody, standard, with 3.5 inches of added width paired with its wider wheels and tires. New, wider 20-inch-by-11-inch Lightweight Carbon Black wheels ride on wide Pirelli 305/35ZR20 tires. The Pirelli 305/35ZR20 all-season performance tires are standard; three-season tires are also available.

Beyond its menacing stance, the newly designed performance hood on the Charger SRT Hellcat Redeye looks even more sinister and provides maximum air intake to the supercharged power plant 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 air box.

The front fascia on the Charger SRT Hellcat Widebody includes the mail-slot grille, providing for additional cool air to travel into the radiator to help maintain ideal operating temperature even in the hottest conditions. Side sills connect the front and rear fascias to help amplify the integrated design.

Beating the heat

Heat is the enemy of any high-performance powertrain, so Dodge//SRT designers and engineers looked for more ways to keep the intake air as close to the optimum temperature as possible.

One key to the engine’s imposing power output is air – and plenty of it. The newly designed, functional performance hood on the SRT Hellcat and SRT Hellcat Redeye provides maximum air intake to the high-output supercharged power plant.

On the Charger SRT Hellcat Redeye, the new functional performance hood, mail-slot grille opening and air box opening near the wheel liner combine to give the high-output engine an 18 percent 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.

2021 Charger SRT Hellcat lineup: More horses, expanded technologies and more features

From 717 to 797 horsepower, Dodge is delivering the most powerful Charger SRT Hellcat lineup ever for the 2021 model year.

Powered by the proven supercharged 6.2-liter HEMI Hellcat V-8 engine, the Charger SRT Hellcat ups the ante by increasing the shift points to 6,100 rpm in automatic mode, which yields a 10-horsepower boost, now delivering 717 horsepower and 650 lb.-ft. of torque.

The innovative, quick-shifting TorqueFlite eight-speed transmission is standard on all Charger models and provides optimized fuel economy while enabling maximum performance with 160-millisecond shifts and rev-matching on Charger SRT Hellcat and SRT Hellcat Redeye.

All 2021 Charger SRT Hellcat models are loaded with standard performance features, including:

Adaptive Damping Suspension — SRT-tuned Bilstein three-mode Adaptive Damping Suspension system includes: Auto mode = sporty but compliant ride; Sport mode = firm, maximum handling; Track mode = firm, maximum handling plus performance shifting and gear-holding feature
Braking system — Braking power comes from the standard Brembo brake system with two-piece, 15.7-inch front rotors and six-piston front calipers for outstanding heat management, thermal capacity and longevity
Electric power steering (EPS) — Electric power steering delivers better steering feel and ease of turning at parking lot speeds. It can be calibrated to optimize steering effort for a variety of driving situations via settings in the SRT Performance Pages
Launch Assist — Launched on the Challenger SRT Demon as a factory-production car first, Launch Assist helps resolve one of the biggest challenges to clean launches and driveline integrity – wheel hop, which happens when tires quickly slip and regain traction at launch, rapidly storing up and releasing energy in the driveline. These high torque spikes can quickly and severely damage driveline components and, up until now, the only solution was to back out of the throttle. Charger SRT Hellcat models use the wheel speed sensors to watch for signs that the tires are slipping/sticking. If hop is detected, the engine control module momentarily reduces torque to maximize traction almost instantly – without the driver having to lift the throttle. Launch Assist reduces loads in the driveline from wheel hop by up to 20 percent
Torque Reserve — Becomes active once the engine speed passes 950 rpm. The system closes the bypass valve, “prefilling” the intake with boost, manages fuel flow to cylinders and manages spark timing to balance engine rpm and torque
Launch Control — Holds the engine at optimal launch rpm and waits for the driver to release the brake. Launch Control then uses engine torque management to optimize wheel slip for maximum acceleration
Line Lock — Engages the front brakes to hold the Charger stationary, but leaves the rear wheels free for a burnout to heat up and clean the rear tires. The system will also let the driver perform a controlled rolling burnout and can engage for up to 200 rear wheel revolutions
Larger induction air box — Sealed to the new functional performance hood for a steady supply of cool outside air, the SRT Hellcat Redeye’s air box includes an additional inlet near the wheel liner
SRT Drive Modes — Accessed via the 8.4-inch Uconnect touchscreen, drivers can tailor their experience by adjusting horsepower, transmission shift speeds, steering effort, paddle shifters, traction and suspension settings. SRT Drive Modes offer selectable settings for Street (Auto), Sport and Track. There is also a custom setting for the driver to select individual preferences
SRT Performance Pages — Brings critical vehicle performance data to the driver’s fingertips, including a real-time dyno graph, g-force heat map and much more

With all of these features, the 2021 Charger SRT Hellcat lineup delivers improved performance numbers and a faster quarter-mile time.

Charger SRT Models	1/4-mile Elapsed Time/Speed	Top Speed
Redeye Widebody	10.6 seconds @ 129 mph	203 mph
