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

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. Hardware: 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 Software: 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 Result: 13.5=575@500 Related Video: This content is hosted by a third party.

2015 Dodge Challenger Drag Pak previewed

Dodge and Mopar have never strayed far from success in drag racing, be it on run-what-you-brung nights at the local strip or at the highest levels of the sport. Hoping to both add to that heritage and capitalize on some of the media spotlight that's shown so brightly on the brand of late, Dodge has given us our first look at the 2015 Mopar Challenger Drag Pak test car.
Though this first iteration doesn't make use of the 707-horsepower Hellcat engine, it seems to be a pretty formidable racing package. Starting with a stock '15 Challenger, Mopar adds a full roll cage built to National Hot Rod Association specs. Rubber front and back is drag racing-ready as well, with 28x4.5-inch tires in the front, and fat 30x9-inch tires out back - all from Hoosier.
Powering the beast is a massive 426-cubic-inch (7.0-liter) Hemi Race V8, with output levels that are still unspecified. A Chrysler 727 automatic transmission connects up to a racing style shift lever, with integral line lock.

NHTSA investigating Ram 1500 models for rear differential failure

The National Highway Traffic Safety Administration is investigating Fiat Chrysler Automobiles and its Ram brand following a number of reports regarding the 2005 Dodge Ram 1500 pickup. According to 15 consumer complaints, the trucks' rear differential locked up while in other cases, the driveshaft separated at its connection to the diff.
Nearly half of the reports claim the truck was traveling at or above 50 miles per hour, while two consumers reported that the diff lockup/driveshaft separation sent their pickups into a spin. Most troubling, though, is that consumers reported little to no sound indicating there was a problem with their truck.
We reached out to Ram for additional information, such as how many vehicles may be affected or what equipment might be fitted that could cause the issue. Unfortunately, the company wasn't willing to elaborate on specifics.
