SRT cars: 707 or 500 hp

Hellcat-Engine-Web Today, Dodge released power ratings for the long-awaited Hellcat V8 engine. They exceeded Allpar’s past estimates of around 650-680 hp and up to 640 lb-ft of torque, coming in at a stunning 707 horsepower and 650 lb-ft. Buyers of the 2015 Challenger SRT Hellcat can limit themselves or other drivers to “just” 500 horsepower (more than the 392’s top rating) by using the black key fob, reserving the red fob for racing or for themselves, according to Chrysler’s Russ Ruedisueli. SRT powertrain chief Chris Cowland reported that the supercharger’s design and specifications were jointly developed by Chrysler and IHI.

The Hellcat engine racks up a lot of “mosts:” most powerful Dodge V8 ever; most powerful Challenger ever; and, last but definitely not least, the most powerful factory muscle car ever.

Look for the 2015 Challenger SRT Hellcat it to begin arriving at Dodge dealerships sometime this quarter.
