The 2012 Dodge Charger SRT8 is all about the engine – a new 6.4 L HEMI V8 with 465 hp and 465 lb/ft of torque; other delights include a new front fascia, 4″ dual exhaust and Harmon Kardon stereo.
During the Cold War, the US held air raid drills with sirens powered by 331cid 185 hp Chrysler HEMI engines, throwing sound out as far as 25 miles away. Noisy fun begins at 2:54. (Thanks Brian!)
The 392 HEMI V-8 in the 2011 Dodge Challenger SRT8 392 pumps out a supremely beefy 470 hp and 470 lb/ft of torque, in addition to having highly damped shocks, 20″ rims and a throatier exhaust.
