The 2023 Dodge Challenger Scat Pack typically achieves a 0-60 mph time of 4.2 to 4.5 seconds. While the 8-speed automatic transmission and Widebody configuration can push times toward the lower end of that range, real-world variables like tire temperature, surface preparation, and density altitude significantly influence these performance metrics.
For muscle car enthusiasts and collectors looking back from 2026, the 2023 model year remains a pivotal moment. As the final production year for the internal combustion engine (ICE) Challenger, the 2023 Scat Pack represents the pinnacle of naturally aspirated HEMI performance. Understanding its 0-60 capabilities requires a deep dive into the 392 cubic-inch engine, the transmission logic, and the physics of putting nearly 500 horsepower to the pavement.
The Heart of the Beast: The 3.92 HEMI V8
At the center of the 2023 Scat Pack’s performance is the 6.4-liter (392 cubic inch) HEMI V8. Unlike the supercharged Hellcat variants, the Scat Pack relies on natural aspiration. This provides a linear power delivery that is often more manageable for 0-60 sprints on non-prepped street surfaces than the high-torque surge of a supercharger.
The engine produces 485 horsepower and 475 lb-ft of torque. In the context of a 0-60 run, torque is the more critical figure. The 392 HEMI is designed to provide a broad torque curve, meaning it pulls hard from low in the RPM range. This is essential for overcoming the vehicle's substantial curb weight—which often exceeds 4,200 pounds depending on the configuration.
The "392" designation is a nod to Dodge’s history, but the modern execution is high-tech. It features a deep-skirt cast-iron block and aluminum alloy heads with hemispherical combustion chambers. The use of variable valve timing (VVT) allows the engine to optimize its breathing across the rev range, ensuring that when the driver mashes the throttle at a standstill, the engine responds with immediate, atmospheric force.
Transmission Dynamics: Manual vs. Automatic
One of the most significant factors in the 2023 Challenger Scat Pack's 0-60 time is the choice of transmission. Dodge offered two distinct options, and the performance gap between them is measurable.
The TorqueFlite 8-Speed Automatic
The majority of 2023 Scat Packs were equipped with the ZF-sourced TorqueFlite 8HP70 8-speed automatic transmission. This gearbox is widely considered one of the best in the industry for performance applications. In "Track" mode, the 8HP70 can execute shifts in approximately 160 milliseconds.
Because the automatic can stay in the powerband more effectively and shift faster than any human can, it consistently delivers the fastest 0-60 times. Furthermore, the automatic allows for more precise "brake torquing" or the use of the built-in Launch Control system, which manages engine RPM and wheel slip far more efficiently than a manual clutch setup.
The TREMEC 6-Speed Manual
For purists, the 2023 Scat Pack was one of the few remaining ways to get a high-displacement V8 with a 6-speed manual transmission. While the TREMEC TR-6060 is a robust, heavy-duty gearbox, it is objectively slower in a 0-60 contest. A skilled driver might achieve a 0-60 time in the high 4-second range, but the mechanical delay of shifting from first to second gear—and the difficulty of modulating the clutch for a perfect launch—usually adds 0.3 to 0.5 seconds to the sprint compared to the automatic.
Widebody vs. Standard: The Traction Factor
The 2023 Challenger Scat Pack was available in two body styles: the standard (narrow) body and the Widebody. This choice affects more than just aesthetics; it is perhaps the most critical mechanical differentiator for 0-60 performance.
The standard Scat Pack comes with 20x9-inch wheels wrapped in 245/45R20 tires. For a car with 485 horsepower, a 245mm rear tire is arguably insufficient for maximum acceleration. Owners of the standard body often struggle with "wheel hop" or excessive spinning when attempting a hard launch.
The Widebody package changes the equation by adding 3.5 inches of width to the car, allowing for 20x11-inch wheels and massive 305/35ZR20 Pirelli performance tires. The increase in the "contact patch"—the amount of rubber actually touching the road—is substantial. This extra grip allows the Scat Pack to put more of its 475 lb-ft of torque into forward motion rather than turning it into smoke. Consequently, the Widebody version consistently tests at the lower end of the 4-second spectrum (4.2–4.3 seconds), whereas the narrow body often hovers around 4.4–4.5 seconds.
Electronic Aids: Launch Control and SRT Performance Pages
To help drivers achieve these times, Dodge equipped the 2023 Scat Pack with a suite of electronic performance tools accessible through the 8.4-inch Uconnect touchscreen.
- Launch Control: This system allows the driver to preset a specific RPM for the launch. Once activated, the driver holds the brake, floors the gas, and the computer holds the engine at the desired RPM. When the brake is released, the system modulates engine torque to maintain the perfect balance between acceleration and tire slip.
- Line Lock: This feature locks the front brakes while leaving the rear wheels free to spin. This is designed for the "burnout box" at a drag strip, allowing the driver to heat up the rear tires to increase grip before a timed run.
- Launch Assist: Built into the ESC (Electronic Stability Control) sensors, this system detects wheel hop—a common issue with independent rear suspensions—and instantly reduces engine torque to prevent drivetrain damage and help the tires regain traction.
- Real-Time Telemetry: The SRT Performance Pages provide the driver with immediate feedback, including 0-60 times, G-force meters, and engine output stats. This allows drivers to see exactly how changes in their technique or environment affect their times.

Real-World Variables: Why Your Time May Vary
While Dodge and various automotive publications cite 0-60 times in the low 4s, many owners find their real-world results are slower. Several physical and environmental factors dictate the final number on the Performance Pages.
Density Altitude and Air Quality
Internal combustion engines are giant air pumps. The 6.4L HEMI is naturally aspirated, meaning it relies on atmospheric pressure to "push" air into the cylinders. At high altitudes (like Denver) or in extremely hot, humid conditions, the air is less dense. Less oxygen means a less powerful explosion in the combustion chamber. It is not uncommon for a Scat Pack to lose 0.3 to 0.5 seconds on its 0-60 time in "bad air" conditions compared to a cool evening at sea level.
Surface Preparation
The 0-60 times published by magazines are often achieved on a "prepped" drag strip surface treated with VHT or other sticky compounds. On standard highway asphalt or concrete, which may be dusty or polished, the Scat Pack will likely spin the tires. Traction is the bottleneck for this car; the engine has more power than the chassis can usually put down on an unprepared street.
Tire Temperature and Compound
The stock Pirelli tires on the 2023 Scat Pack are "summer" tires. They are designed to operate best when they are warm. If you attempt a 0-60 run on a 40-degree morning, the rubber will be hard and lack grip, leading to excessive wheel spin. Conversely, if the tires are too hot from multiple runs, they can become "greasy" and lose efficiency.
The "Last Call" Context and Collector Value
As we look back from 2026, the 2023 Challenger Scat Pack holds a special place as one of the "Last Call" models. While the Scat Pack wasn't a limited edition in the same way as the Demon 170, every 2023 model features a special "Last Call" plaque under the hood.
This model year was the final opportunity for buyers to purchase a brand-new, naturally aspirated HEMI Challenger. In the years following 2023, the industry shifted toward smaller-displacement turbocharged engines (like the Hurricane Straight-Six) and electrification. The 0-60 time of the 2023 Scat Pack—while slower than the modern 2026 electric counterparts—is valued more for the experience of achieving it: the vibration of the big V8, the roar of the active exhaust, and the mechanical feedback that only a large-displacement engine can provide.
Common Modifications to Improve 0-60 Times
For owners who were not satisfied with a 4.4-second sprint, the 2023 Scat Pack platform was highly receptive to minor modifications.
- Drag Radials: Replacing the stock street tires with street-legal drag radials (such as Mickey Thompson ET Street S/S) is the single most effective way to drop 0-60 times. With enough grip, a Scat Pack can dip into the high 3-second range.
- Mid-Muffler Delete: While this doesn't significantly add horsepower, it is a popular modification for the "sound" of the 0-60 run.
- Cold Air Intakes: Systems like the Mopar Shaker or various aftermarket intakes aim to bring cooler air into the 392 HEMI. While the gains are modest (5-10 hp), every bit helps in a heavy car.
- Weight Reduction: Removing the passenger seat and rear seats—a common practice for track days—can shave nearly 100 pounds off the car, improving the power-to-weight ratio.
Frequently Asked Questions
Is the Scat Pack faster than the R/T?
Yes, significantly. The 2023 Challenger R/T uses a 5.7L HEMI producing 375 horsepower, with a 0-60 time typically around 5.0 to 5.2 seconds. The Scat Pack's 6.4L engine provides over 100 additional horsepower, cutting nearly a full second off the 0-60 sprint.
Does the 2023 Scat Pack require premium fuel to reach these times?
Yes. To achieve the advertised 485 horsepower and the quickest acceleration times, Dodge recommends 91 octane (or higher) premium unleaded fuel. Using lower octane fuel may cause the engine's knock sensors to retard timing, resulting in reduced power output and slower 0-60 times.
How does the 0-60 time compare to a Hellcat?
The 2023 Hellcat, with its supercharged 6.2L V8 producing 717+ horsepower, is faster but also much harder to launch. While a Hellcat is capable of mid-3-second 0-60 times, on a standard street surface, a Scat Pack Widebody can often stay neck-and-neck with a Hellcat for the first 60 feet because the Hellcat simply has too much power for its tires to handle.
Can a manual Scat Pack beat an automatic?
In a 0-60 race, it is extremely unlikely. The TorqueFlite 8-speed automatic is optimized for the engine's torque curve and shifts with a speed and consistency that a human using a clutch and physical gear lever cannot match. The manual is chosen for driver engagement, not for winning 0-60 drag races.
What is the 1/4 mile time for a 2023 Scat Pack?
A 2023 Challenger Scat Pack typically completes the quarter-mile in 12.1 to 12.5 seconds at a trap speed of approximately 112-115 mph. The Widebody automatic models are generally the most consistent performers in this category.
Final Recommendation for Owners and Buyers
To get the most out of a 2023 Challenger Scat Pack’s 0-60 potential, focus on traction management. If you own a standard-body model, upgrading from the 245mm stock tires to a 275mm or 285mm performance tire will yield the most immediate improvement in acceleration. For those with the Widebody, ensuring the 305mm Pirellis are properly warmed and utilizing the "Launch Control" feature set to approximately 2,200–2,500 RPM will typically yield the best results on a typical road surface. Always remember that these performance metrics should only be tested in controlled environments, such as a local drag strip or sanctioned track event, to ensure safety and legality.
