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.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

2020 Dodge Durango SRT Drivers' Notes | When excess is a good thing

Performance SUVs and crossovers from non-luxury brands are still in a nascent stage of development. Models like the Porsche Cayenne Turbo, BMW X5 M and others are on subsequent generations of their high-performance high-riding machines. Meanwhile, the 2019 Dodge Durango SRT is still refreshingly new. It’s also about as American as it gets. Dodge shoehorned in the 6.4-liter V8 and gave it an exhaust system that screams ‘Murica at anyone who strays too close. It makes a glorious 475 horsepower and 470 pound-feet of torque, completing the sprint to 60 mph in 4.4 seconds. An eight-speed automatic transmission sends power to all four wheels, which means you have traction — something the Challengers and Chargers with this engine could use a bit more of. Despite the Dodge being far cheaper than other big, high performance luxury SUVs out there, it still isnÂ’t cheap. The SRT has a base price of $64,490. Ours stickers for a much higher $78,235. Unsurprisingly, Dodge makes you pay the big bucks for most of the luxury features and customization options. A $2,395 Technology Group adds adaptive cruise control, lane departure warning and forward collision avoidance systems. Fancy interior materials like a suede headliner, nicer materials on the instrument panel and carbon fiber inserts can be had in a $2,495 package. The stripes are $1,295, and the 20-inch wheels cost $995. To get the second row console with an armrest and storage, youÂ’ll have to pay an extra $595. A $78,235 Durango might sound like a completely egregious amount of money, but itÂ’s still far below what youÂ’ll pay for a BMW X7 or Mercedes-Benz GLS that goes just as fast. ItÂ’s no muscle SUV for the people, but it is a muscle SUV for more people than could afford one previously. Assistant Editor Zac Palmer: An American SUV with a giant V8 feels like a superior descendant of muscle cars than most other “muscle cars” on sale today. Both the Mustang and Camaro slant toward the sports car side of things, leaving FCA to carry on the muscle car tradition. And man, Dodge carries it on well. FCA could slot its 6.4-liter V8 into nearly anything and IÂ’d love it, so it was no surprise that I enjoyed it thrashing it about in this behemoth of an SUV. Traction off the line was one major benefit in the Durango over the Charger and Challenger. Matt the throttle and it just leaps forward, similar to the Jeep Grand Cherokee SRT.
