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".

Mopar teases four of 'nearly 20' SEMA Show concepts

Yesterday it was Chevrolet. Today, Mopar has dropped some SEMA knowledge, releasing a quartet of teaser images that give us some indication of what kind of cars, trucks, and crossovers Fiat, Chrysler, Dodge, Jeep, and Ram will be showing in Las Vegas. Like Chevy, Mopar's concepts utilize both production and concept accessories, although Fiat Chrysler has gone a bit more indepth on at least one of its concepts. Immediately, the most tantalizing teaser is the one shown above. Yes, that's the back of a Challenger, and aside from the bright orange accents on the gray body, you should take notice of the badge mounted on the spoiler – yes, that says "GT AWD." To be honest, such a vehicle wouldn't be a huge shock, as both the Challenger's LX platform-mates, the Dodge Charger and Chrysler 300, are offered with all-wheel-drive options. Still, adding such a vehicle to the production cycle would give Dodge a leg up on the rear-drive only Ford Mustang and Chevrolet Camaro. Aside from that concept, FCA has also released teasers of a Ram-based concept, a 300-based concept, and what we're guessing is a Fiat 500X. We can't wait to see what the actual Fiat concept has to do with kiteboarding. As for the 300 and Ram, there's not a lot of hints on what sort of styling details they'll contain. The Chrysler has additional LED accents and what we're guessing is matte blue paint, while the Ram is based on a Hemi-powered 1500 with Rebel styling cues. This is just a very tiny sample of Mopar's final SEMA roster, which include "hundreds" of parts. There should also be a total of 20 vehicles covering all four former Chrysler Group brands, as well as Fiat. Naturally, we'll have plenty to report on each vehicle once the SEMA show kicks off in the next couple weeks.

The last time Dodge recycled the Demon name, it was for a Miata fighter

We and the rest of the automotive world are eagerly awaiting the reveal of the Dodge Challenger Demon. And why wouldn't we be? It's going to be a Hellcat, but with less weight, bigger fenders, more performance, and more Vin Diesel. This isn't the first time we've been excited about a Demon from Dodge, though. Ten years ago, Dodge had another demonic car, but it was very different from the new one. The Demon of 2007 was a lithe little roadster that looked primed and ready to take on the Miata, as well as the now-departed Solstice and Sky twins. The Demon was just under an inch shorter than the MX-5 and the Solstice, and it packed a 172 horsepower 2.4-liter four-cylinder that fell right between the Miata's 170 and the Solstice's 177 outputs. Dodge's estimated the curb weight, which for a concept is largely theoretical, also slotted between the two cars at 2600 pounds. That was about 150 more than the Mazda, and about 200 less than the Pontiac. The pitch perfect specifications were presented in a crisp two-seat roadster wrapper. In many ways, it looked like a baby Viper, with a menacing crosshair grille, slanted headlights, and fat rear fenders. The Demon's line's were brutally simple and geometric, too. They didn't seem far removed from the first-generation Audi TT. The interior was also plain and simple. The key highlights were a horizontal aluminum accent that ran the width of the dash, echoed by an aluminum-covered center console. The instrument cluster was uncluttered, with just four gauges, and the only controls were some climate knobs, a double-DIN head unit, and a six-speed manual. It turns out that the 2007 Demon didn't drive very well, though. You see, we actually drove this concept back in the day, and like many concepts, it still had a long way to go to be production ready. The gearbox would grind, the ride quality was terrible. However, the interior was roomy, and the engine sounded suitably grumbly, if a bit coarse. At the time, we said Dodge should absolutely build the little roadster. In retrospect, the company probably made the right decision not to invest in the Demon. The small rear drive sports car segment was, and still is, an extremely niche market. It would have been a big investment for little return, something FCA today is trying to avoid. This is all before taking into account the fact that the recession was just around the corner. In the end, we can't be too sad though.
