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".

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.

Ram 1500 mule caught sporting Mega Cab configuration

Our intrepid spy photographers have once again captured an unusual test mule out in the wild. This time we have a Ram 1500 that looks a little lengthy in the middle. We're pretty certain this is a 1500 and not a heavy duty model judging from the grille and hood. That said, FCA clearly went to great lengths to hide the cab. It's still clear that the rear section is longer than your typical quad cab, leading us to believe that the Mega Cab option will return to the 1500 line. Other interesting details are the covered tailgate and the Chrysler steering wheel in the interior. We're not entirely sure why it's covered up, as it doesn't appear to have a different function, but there could be some styling tweaks for a new trim level. The one part we can see is the tailgate handle, which may reveal some updated camera abilities as the normal location shows a differently shaped camera lens. There are also two small spots that could be cameras, but it's tough to say for sure. Will we see 360-degree imaging on the next Ram? The steering wheel is an unusual inclusion as well. Our photographer suggests that it could be necessary for using the latest UConnect infotainment system. Other than the wheel though, the interior looks identical to the current model. This updated cab option also leaves us wondering about the future of the Ram line. We have documentation that shows FCA plans to launch some type of refreshed Ram for the 2018 model year. So it's possible we're looking at an early test mule for that updated model, and the new cab option could be launched at the same time. In many ways, this Ram brings up more questions than answers.
