Chrysler unveils Dodge Challenger SRT Hellcat with ’600-plus horsepower’

Just one month after its facelifted muscle cars debuted at the 2014 New York Auto Show, Chrysler has taken the wraps off its high-performance Dodge Challenger SRT models.

Naturally, the biggest news with the 2015 Dodge Challenger SRT is what lies under the hood. It’s still powered by a 6.4-litre normally-aspirated 392 Hemi V8 under the hood, but output has been bumped up to 480 horsepower and 475 lb.-ft. of torque. It can still be paired to a proper six-speed manual transmission, but Chrysler’s new eight-speed automatic transmission is now optional.

But the Challenger SRT you really want is the one powered by the all-new, supercharged 6.2-litre Hemi V8 engine. Also known as the Challenger SRT Hellcat, Chrysler says this is the most powerful of any V8 engine fitted into its cars. Exactly how powerful is powerful? Although Chrysler hasn’t detailed a specific output figure, it promises “600-plus” horsepower. And like the “lesser” Challenger SRT, the Hellcat can be paired to either a six-speed manual or eight-speed automatic.

In terms of its specific powertrain bits and pieces, the Hellcat V8 features a crankshaft made out of forged steel, as well as forged alloy pistons and connecting rods, heat-treated aluminum-alloy cylinder heads, and last but not least, die-cast rocker covers finished in Hemi Orange. Other changes to the 2015 Challenger SRT and SRT Hellcat include adjustable Drive Modes pre-configured with Default, Sport, Track and Custom settings, as well as uniquely-tuned ABS and stability control systems, and six-piston Brembo brake calipers with two-piece, 390-millimetre rotors up front.

In addition to unique cosmetic tweaks inside and out, the Challenger SRT Hellcat rides on lightweight, 20-inch alloy wheels finished in matte black wrapped by Pirelli P Zero Nero rubber. Optional on the Hellcat are 20-inch bronze alloy wheels and dedicated Pirelli P Zero summer performance tires.
