2015 Dodge Challenger SRT Hellcat

In May, Dodge officially announced the brand new 2015 Dodge Challenger SRT, boasting a supercharged 6.2-liter HEMI Hellcat engine.

At the time, it was touted as 600-plus horsepower. This week, the brand announced official results of an unprecedented 707 horsepower and 650 lb.-ft. of torque, making it the most powerful muscle car ever.

The Challenger’s new engine is the first factory supercharged HEMI, as well as Dodge and SRT’s first application of V-8 supercharger technology. For the first time in Chrysler Group history, the all-new 2015 Challenger SRT Hellcat comes standard with two key fobs — red and black. The red key fob is the only key that can unlock the full 707 horsepower and torque potential, while the black key fob limits the driver to a reduced engine output of 500 horsepower.

Additionally, the 2015 has been redesigned and totally re-engineered with performance-enhancing technologies inside and out, including the new TorqueFlite eight-speed automatic transmission and an all-new interior inspired by the classic 1971 Challenger.

The 2015 line-up includes the Challenger SXT, coming with a standard Pentastar V-6 engine combined with the TorqueFlite eight-speed transmission that delivers 300 horsepower; the Challenger R/T boasts the high-torque 5.7-liter HEMI, now paired with the TorqueFlite eight-speed or six-speed manual transmission; and the 6.4-liter HEMI Challenger Scat Pack that delivers 485 horsepower and 475 lb.-ft. of torque with the TorqueFlite eight-speed or six-speed manual.

The 2015 Dodge Challenger and Challenger SRTs are will arrive at dealerships in the third quarter of 2014.
