The most powerful V-8 in Dodge's history is slapped between the fenders of the new 2015 Dodge Challenger SRT Hellcat, which uses a supercharger to force-feed air into a 6.2-liter V-8 for an estimated 600-plus horsepower. The stout V-8 is an optional engine on the redesigned 2015 Challenger SRT that, like other 2015 Challengers, shows off an all-new interior favoring an upscale, modern design over the previous year's retro look.
Base Challenger SRT buyers now have 485 hp, up from 470 hp, and a newly available eight-speed automatic transmission replaces the five-speed automatic. Back to the Hellcat — it's available with the eight-speed automatic transmission or a six-speed manual with nostalgic shifter-ball knob. Hellcat production is expected to begin in the third quarter of 2014.
