The 2012 Dodge Charger SRT8 debuts at the 2011 Chicago Auto Show
The heart of the 2012 Dodge Charger SRT8 is the 392 cubic inch, 6.4L Hemi V8 which, in this application, churns out 465 horsepower and 465lb-ft of torque. That is 40 more horsepower and 45 more lb-ft of torque than the old 6.1L Hemi found in the previous SRT-Chargers and thanks to the active intake manifold and revised camshaft, the new 392ci Hemi offers 80 more lb-ft of torque at lower RPMs. Thanks to the Chrysler Fuel Saver system, this new Hemi offers better fuel economy than the old engine with a combined effort of a multiple displacement system and the new active-valve exhaust system – although no exact specs have been given. More importantly (to the average SRT8 buyer), the 6.4L Hemi allows the new Charger SRT8 to dash from 0 to 60 in under 5 seconds in route to a top speed around 175mph and according to Chrysler, the new Charger SRT8 will be capable of quarter mile times in the high 12 second range, although with the Challenger SRT8 running in the 12.40s with the same 6.4L Hemi (with 5 more stated horsepower), I suspect that number to be conservatively high. My safe money is on the new SRT8 sedan running the quarter in the mid 12 second range in stock form.
