2011 Dodge Challenger SRT8 392 Debuts
470 horse 392 HEMI in front of a Tremec 6-speed stick... now THAT is a Challenger!New 392 HEMI V-8 Offers Wide Torque Range
The return of the legendary 392-cubic inch HEMI powertrain back to the street in the Dodge Challenger SRT8 392 provides another step in showcasing the evolution of the performance brand.
Pumping out 470 horsepower and 470 lb.-ft. of torque, the newest HEMI engine in the SRT product lineup provides an additional 90 lb.-ft. of torque at 2,900 rpm versus the previous 6.1-liter V-8 engine. The added torque allows for inspired standing starts and improved straight-line performance while new, performance-tuned motor mounts improve idle stability and ride control at any speed. An active intake manifold and high-lift camshaft with cam phasing provides maximum low-end torque while optimizing high-end power.
The 2011 Dodge Challenger SRT8 392 is available with either the standard five-speed automatic transmission with Auto Stick or an available Tremec TR-6060 six-speed manual transmission that was first offered on the 2008 Dodge Viper SRT10. An improved heavy-duty clutch provides easier shift engagement.
