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".

What does Jeep have cooking with this stretched Cherokee?

Chrysler has been spotted testing what appears to be a stretched Jeep Cherokee prototype. Which seems odd, considering that Jeep already makes a Grand Cherokee, and that's an entirely different model. The question then is just what the company has in the works here. We don't know for sure – but we do have some ideas. We're anticipating a new Grand Wagoneer to serve as the brand's flagship model, but stretching the Cherokee's wheelbase to leapfrog the Grand Cherokee's would take more than eight inches – and stretching a "compact" platform to get there wouldn't seem to make a lot of sense. Alternatively Jeep could be looking to wedge a new model into its lineup in between the Cherokee and Grand Cherokee, potentially offering a third row of seats and wearing the Wagoneer name - sans the "Grand" - as part of a new range of seven-seaters. Just what the point would be, however, when the Dodge Durango already offers three rows based on the same platform as the Grand Cherokee, is a bit of a mystery. Another possibility is that it's not a Jeep at all, but rather a Dodge. The brand is in need of a replacement for the current Journey, and we're also waiting to see what FCA does to replace the Grand Cherokee since it unveiled the Chrysler Pacifica to replace the Town and Country. More of a crossover approach could take the Cherokee's Compact US Wide (CUSW) platform as its starting point, but stretched like this prototype to offer more space. Whatever it is, we're sure this won't be the last we'll have seen of it, so watch this space. Related Video:

Cars.com runs 11-second quarter with Dodge Charger Hellcat

The Dodge Charger SRT Hellcat and its Challenger sibling are two of the heroes of the modern performance world. With a headline-grabbing 707 horsepower from a supercharged 6.2-liter V8, their output even shames many supercars. But how quick can one really cover a quarter mile? Cars.com recently decided to find out by taking a Charger Hellcat to the drag strip to see if the sedan lived up to Dodge's 11-second claims. The results were quite impressive. After 13 quarter-mile runs of adjusting variables like the tire pressures and the car's various electronic aids, the Charger Hellcat managed a pass in 11.03 seconds at 126.61 mph – the pinnacle result of the day. This car was mechanically stock and wore the optional Pirelli P Zero tires. According to Cars.com, other quick sprints reached 11.09 seconds and 11.1 seconds, which even beat the site's 11.41-second best from a Challenger Hellcat last year. Getting the Hellcat's prodigious power down without losing traction was a challenge, even on the summer tires. Cars.com thought it had a run that could have dropped below 11 seconds, but then the wheels spun. Using the factory-recommended pressures, the Charger Hellcat was no still slouch with an 11.27-second time recorded, but taking things down to 25 psi proved the quickest at the strip. We already knew that the Charger Hellcat was a wonderful vehicle for eating up huge gulps of asphalt at high speeds and could verify its 204-mile-per-hour top speed (quite a bit faster, incidentally, than the Ferrari California T's 196 mph top-speed). Apparently, the 11-second quarter-mile claim is just as accurate. Also, for any curious owners, the Cars.com story divulges many of the tweaks required to reach this seriously quick time.
