This naturally aspirated V8 produces 375 horsepower and 390 pound-feet of torque, channeled power to the rear wheels through a robust automatic transmission that was tuned for both daily comfort and spirited highway merging.

Across SXT and R/T trims, the 5.7 Hemi delivers consistent output, while the optional performance calibration and transmission mode selectors allow drivers to tailor shift points and throttle response to match their style.

The chassis strikes a balance between sport and comfort, with firm springs and shocks that control body roll during cornering while still absorbing road imperfections at a civilized pace for long-distance drives.

Braking response is confident, with vented rotors up front providing solid bite, and the steering weight well-suited for urban parking and expressway cruising alike.
