The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

For every action...

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages.

Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension.

The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself.

An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability.

Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues.

  • 35 percent lower rate front springs/28 percent lower rate rear springs
  • 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar
  • Drag-tuned Bilstein Adaptive Damping Shocks
  • Rear = F/F and Front = F/S
  • F/F – F/S maintained @ wide open throttle (WOT)
  • F/F – F/F < WOT
  • Traction control disabled/ESC maintained
  • 13.5=575@500
