Performance Benchmarks
Launched on October 13, 2018, the Hellcat Redeye shattered expectations by outpacing the base Hellcat by a tenth-second in quarter-mile runs, clocking 10.8 seconds for Widebody models and 11.1 seconds for standard versions, both at 131 mph trap speeds. Independent tests confirm 0-100 mph in 11.8 seconds and lateral acceleration of 0.98 g, proving its track prowess beyond straight-line speed. At full throttle, it guzzles 5.4 liters per minute, emptying its 18.5-gallon tank in under 11 minutes.
| Performance Metric | Hellcat Redeye (Widebody) | Standard Hellcat |
|---|---|---|
| 0-60 mph | 3.4 seconds | 3.6 seconds |
| Quarter-Mile | 10.8 sec @ 131 mph | 11.7 sec @ 115 mph |
| Top Speed | 203 mph (327 km/h) | 199 mph |
| Braking 60-0 mph | 94 feet | 97 feet |
| Skidpad | 0.98 g | 0.95 g |
These figures, verified in 2021 Edmunds testing, highlight upgrades like 41-spline half-shafts to prevent axle failures during launches.
Chassis and Handling Upgrades
The Redeye Widebody variant, introduced alongside the 2019 model year, adds 3.5-inch wider fenders, 305/35R20 Pirelli P-Zero tires on 20x11-inch wheels, and adaptive suspension damping for sharper cornering. Launch control pre-fills the supercharger bypass valve and uses a two-step rev limiter, optimizing boost from a standstill. Brembo 6-piston front brakes with 15.4-inch rotors deliver supercar-stopping power, essential for managing 4,443 pounds of curb weight.
- Activate Launch Control via Uconnect screen or steering wheel.
- Select track mode for stiffened damping and maximized traction.
- Engage line lock to heat rear tires for 20 seconds.
- Hold brake, floor accelerator to 2,500 rpm, then release for liftoff.
- Monitor Torque Reserve to maintain supercharger spool during rollout.
Fuel Economy and Practicality
Despite its ferocity, the Hellcat Redeye achieves EPA ratings of 13 mpg city, 22 mpg highway, and 16 mpg combined, with a 407-mile highway range on its 18.5-gallon tank. Cylinder deactivation seamlessly switches to V4 mode during cruising, balancing thirst with usability for daily drives. Real-world tests show 240 miles in city conditions, underscoring its dual nature as street-legal missile.
Historical Context and Legacy
Unveiled in 2018 as a bridge between the 707-hp Hellcat and limited-run 840-hp Demon, the Redeye arrived amid muscle car wars, forcing competitors like Chevrolet to revive the ZL1 1LE. By 2021, Charger variants joined with identical 797-hp specs, expanding the lineup to sedans. Production continued through 2023, with over 10,000 units sold, cementing its status as the most powerful production V8 ever at launch.

Pricing and Availability
Starting at $71,170 for the 2021 Challenger SRT Hellcat Redeye coupe, Widebody models climbed to $76,999, excluding $1,700 gas-guzzler tax and destination fees. Used 2023 examples now fetch $80,000-$100,000 in 2026 markets, boosted by collector demand post-Dodge's V8 era pivot. Options like the 3.09 rear axle ratio added $1,095 for top-speed runs.
| Trim Level | Base MSRP (2021) | Key Features |
|---|---|---|
| SRT Hellcat Redeye | $71,170 | Standard body, 11.1-sec quarter-mile |

Competitor Comparison
The Hellcat Redeye dominated 2019-2023 with unmatched power-per-dollar, outgunning the 650-hp Camaro ZL1 (3.5-sec 0-60) and 755-hp Mustang Shelby GT500 (3.3-sec) in quarter-mile traps. Its interchiller-unique among production cars-cools intake air via A/C, sustaining power longer than rivals. Today, in May 2026, it remains a benchmark as electrification rises.
- Vs. GT500: Redeye cheaper, torquier low-end
- Vs. ZL1 1LE: Superior straight-line, less nimble
- Vs. Demon: More accessible, slightly detuned
Even in 2026, the Hellcat Redeye's specs-born from 2018 engineering-defy time, blending raw V8 fury with street legality. Its launch amid Detroit's horsepower arms race, quoted by SRT boss Tim Kuniskis as "the most capable muscle car ever," ensures enduring appeal.
Weight distribution favors the rear at 56/44 percent, aiding traction, while electric power steering tunes precisely for this 4,449-lb beast. Drag strip records from 2019 NHRA events show consistent sub-11-second passes, outlasting tires in minutes.
"Dodge has detuned it to 797hp... quarter-mile time of 10.8@131mph." - Street Machine
