Our new ground pounding 392/6.4L HEMI® has been tearing up the asphalt since the beginning of the year. This torque monster comes standard in our new Challenger and Charger SRT8 models (and yes, we also share it with the 2012 Chrysler 300C and Jeep® SRT8 family members). Its mind numbing performance has rewarded its owners with 12-second ET slips at the drag strip. Want to know how we extracted 470 horsepower and 470 lb.-ft. of torque while increasing gas mileage? Check out the video from the 6.4L HEMI Technology Review Conference and hear it first hand from Gary Rogers who is the head engineer on our latest incarnation of the GEN III HEMI.
