Hellcat: 411 lb-ft at 1,200 rpm (with video)

by David Zatz on

The Hemi Hellcat V8 used in the Dodge Charger and Challenger not only generates 707 peak horsepower and 650 pound-feet of torque; it also builds up a stunning 411 pound-feet of torque at just 1,200 rpm, providing instant-on responsiveness, according to Charger/Challenger SRT chief engineer Darryl Smith.

While showing social media folk a model Hellcat engine, Mr. Smith talked about the custom-designed, 2.4-liter supercharger, pointing out that while they started with the 392 (6.4 liter) SRT Hemi, they ended up changing 90% of the parts to deal with the added power.

On the track, we found that the Hellcat, while moderately easy to drive smoothly even with the “red key,” would jump instantly to even moderate presses on the gas pedal. It easy easy to race to over 120 mph, in the rain, on a short straightaway, despite a slow, gradual increase in power (to avoid spinning out on the treacherous surface).

More experiences will be reported on Monday; and you can listen to the Hellcat Chargers and Mr. Smith’s revelations in this brief video.
