For drivers who want the maximum factory power available in a Chrysler sedan, the 6.4L 392 HEMI® V8 is the top option. The 5.7L is capable, but the 392 sits in a higher performance tier.
After a long absence, this engine returned for the 2023 Chrysler 300C Final Edition. With only 2,000 units produced for the U.S. market, it represents the peak of American muscle luxury.
The 392 name comes from its displacement in cubic inches, a historic number tied to Chrysler performance. This naturally aspirated engine delivers big power without turbochargers, giving you immediate throttle response for merging in traffic.
| Feature | Specification |
|---|---|
| Horsepower | 485 hp @ 6,100 rpm |
| Torque | 475 lb-ft @ 4,100 rpm |
| 0-60 Time | 4.3 seconds |
| Quarter Mile | 12.4 seconds |
| Transmission | 8-Speed Automatic |
| Drivetrain | Rear-Wheel Drive (RWD) with Limited Slip Differential |
The 2023 Chrysler 300C 6.4L includes a standard Active Exhaust System that blends comfort with a more aggressive sound when you get on the throttle.
The Tech: An electronically controlled valve system automatically opens the exhaust pipes when you press the gas pedal firmly.
The Result: At cruising speeds on I-465, the cabin stays refined. When you accelerate to pass, the valves open for a deep V8 growl, letting everyone in Westfield know this is no ordinary sedan.
Exclusivity defines this powertrain in the modern lineup. Unlike other engines shared across multiple trims, the 6.4L HEMI appears in only one specific model for this era.
This stands as the only 300 sold in the U.S. from 2015 to 2023 to feature the 6.4L engine. To handle the power, it comes standard with red 4-piston Brembo® brakes and Active Damping Suspension.
Note: If you see a listing for a Chrysler 300 SRT from 2016 to 2022, be cautious. That model was not sold in the United States. The 2023 300C is the authentic U.S.-market performance flagship.
Both engines are V8s, but they serve different purposes. The numbers show why the rare 392 is worth the search.
