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".

The Dodge Demon sheds some weight in pursuit of speed

The Dodge Demon teaser train isn't stopping until it hits New York City. In case you need a reminder, the upcoming Demon is the more pedestrian Hellcat's stripped-down and hopped-up sibling that promises to be built for the sole purpose of traveling a quarter-mile mile quicker than any of its rivals. The weekly video rollout on www.ifyouknowyouknow.com continues with the latest sneak peak, "Reduction." While there were early rumors that the Demon may pack an all-wheel-drive system and in turn gain enough grip to rotate the Earth underneath it, Dodge and SRT look to be going down a simpler route. The press release reveals the Demon is 200 pounds lighter than the standard Hellcat. It's unclear where all that weight is coming from, but at nearly 4,500 pounds, the Challenger Hellcat could stand to go on a bit of a diet. The video hints at adjustments to the wheels, steering, suspension, and brakes, as well as some modifications to the car's interior. Don't be surprised if the Demon is a bare bones stripper model with no back seat, no A/C, and no radio. Who needs music when you have 2.4-liter supercharger and a 6.2-liter Hemi V8 making sweet love under the hood?

2015 Dodge Challenger SRT Hellcat gets brace of new videos

Yesterday's big announcement focusing on the new Dodge Challenger SRT Hellcat had plenty of stuff going for it - information, pictures and the rabid enthusiasm that always accompanies such an eagerly anticipated reveal. What it was lacking, though, was a proliferation of videos of the new model.
Sure, yesterday's news came with one clip, but today, Dodge has come through with five videos. We've arranged them in what we think will be the most entertaining order, covering the powertrain, before moving on to exterior and interior design, then on to a full CGI dissection of the SRT Hellcat before capping things off with a piece on the non-supercharged Challenger SRT392.
Take a look below for all five videos, then head into Comments and let us know what you think.
