The 2008 Charger RT with a 5.7-liter HEMI V8 makes about 345 horsepower.
In official ratings, the 5.7 HEMI in the Charger RT delivers roughly 345 hp (SAE net) at about 5,200 rpm, with around 375 lb-ft of torque available near 4,000 rpm. This output helped give the late-2000s Charger RT strong acceleration for a full-size sedan of its era, and the exact figure can vary slightly by market, transmission choice, and drivetrain configuration.
Context and lineup
During the 2006–2008 period, the Charger offered multiple engine options. The 5.7L HEMI was the powerplant for the RT trims, providing a substantial upgrade over the base V6 engines. A higher-performance SRT8 model used a larger 6.1L HEMI with more horsepower, but that engine is not the one in the standard 5.7 HEMI Charger.
Notes on ratings
Horsepower figures are typically SAE net ratings for U.S.-spec vehicles of that era. Subtle differences can appear between markets or with different transmissions, but the widely cited figure for the 2008 5.7 HEMI Charger is approximately 345 hp and 375 lb-ft of torque.
Summary
In summary, the 2008 Dodge Charger powered by a 5.7-liter HEMI V8 delivers about 345 horsepower and around 375 lb-ft of torque, making it a capable performance sedan for its time. For a specific car, refer to its window sticker or VIN documentation to confirm the exact rating.
