What is a 5.7 Dodge Charger?

The 5.7 Dodge Charger refers to a Charger equipped with Dodge’s 5.7-liter Hemi V8 engine. It’s not a separate model or trim name by itself, but rather a powertrain option that has appeared in various Charger generations, most commonly in the R/T variants. In short, it’s a V8-powered Charger, not a standalone car.

Engine, power, and how it drives

The 5.7-liter Hemi is Chrysler’s classic V8 offer in the Charger lineup, known for its deep, muscular sound and strong mid-range torque. The engine uses a hemispherical combustion chamber design and a pushrod (OHV) architecture, with modern refinements such as variable valve timing and, on some models, cylinder deactivation (MDS) to improve efficiency during light cruising. Output varies by year and configuration, but a typical 5.7 Hemi Charger produces roughly 370 horsepower and around 395–410 lb-ft of torque, paired with an automatic transmission and rear-wheel drive as the standard setup. Some years offered all-wheel drive on certain configurations, though the 5.7 Hemi is most commonly associated with rear-wheel drive for that classic V8 experience.

Because of its age and lineage, the 5.7 Hemi Charger blends traditional V8 performance with modern electronics, including drive modes, selectable performance calibrations, and driver-assistance features that evolved over time. The result is a car that prioritizes straight-line speed and a visceral sound over the efficiency-focused approach of smaller engines.

The driving experience is defined by a forceful launch, a broad torque curve, and a soundtrack that reflects the engine’s V8 heritage. Fuel economy, unsurprisingly, sits lower than four-cylinder and V6 Chargers, especially when the throttle is worked hard on a highway on-ramp or a city crawl.

Key specifications and how they changed over time

Below are the core attributes most buyers associate with a 5.7-liter Hemi-equipped Charger and how those attributes tend to present across model years. This overview uses typical figures and common configurations seen in the Charger lineup.
