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.

Subaru Impreza WRX, Dodge Charger police car from 'Baby Driver' are for sale

Fans of " Baby Driver," now is your chance to own some seriously cool bits of movie memorabilia. Allpro Subaru is currently selling two of the cars from the film. The first is one of the red Subaru Impreza WRXs that were used for some of the film's signature stunts, which made the red rally sedan the de facto hero car of the movie. There were a number of stunt cars used to represent the hero car, including a modified WRX and an STI with a WRX wing. This particular one, a 2006 model, is a little more interesting, as it was the one that was converted to rear-drive to make it easier to complete stunts with it. According to the description, it also has a turbocharger from a 2004 STI to make more power, which fits what stunt driver Jeremy Fry told us. The description reveals other interesting tidbits. The car does have a clean title and has 158,000 miles on it. Obviously some of those miles were a bit rough, and the description notes that the stunt driving has led to some cosmetic defects. The AutoCheck vehicle history report reveals more. Apparently this Impreza WRX led a rough life before filming, as it had four mild to moderate crashes reported. It also appears that it will need the Takata airbag replaced. But on the plus side, this car is a unique piece of car and film history, and its rear-drive layout should make it interesting to drive. On top of that, it also has a leather interior that appears to be in good shape. View 5 Photos You'd better have a healthy bank account before trying to buy this WRX. As of writing, the bidding has reached $40,300. If that's too pricey, though, Allpro Subaru has yet another car from the movie. It's a 2011 Dodge Charger police car in Atlanta, Ga. police livery, complete with a V8. It's also pretty thoroughly wrecked, though the description says that it is drivable. Based on the bullet holes in the windshield, the Charger appears to be the one used in the (mild spoiler alert) final showdown between Baby and Buddy. But because this car is much less famous and in far worse shape, it's also much cheaper. Bidding has only reached $3,000 at the time of writing.

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".
