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 best cars we drove this year

Six hundred and fifty. That's roughly how many cars pass through the hands of Autoblog editors every year, from the vehicles we test here at home, to the cars we drive on new product launches, testing roundups, long-term cars, and so on. Of course, our individual numbers vary due to several reasons, but at the end of the day, our team's repertoire of automotive experience is indeed vast. But let's be honest, some cars certainly stand out more than others. So as the year's about to turn, and as we're readying brand-new daily cat calendars for our cubicles, our editors are all taking time to reflect on the machinery that made this year so special, with one simple, open-ended question as the guide – a question that we're asked quite frequently, from friends, family, colleagues, and more. "What's the best car you drove this year?" Lamborghini Huracan When I review the list of everything I drove in 2014, picking an absolute favorite becomes almost impossible. I mean, how does one delineate between the joy offered by cars as different as the Alfa Romeo 4C, Volkswagen Golf R, Mercedes-AMG GT S and even the humble-yet-wonderful Chevy Colorado? Okay fine, I'll just pick the Lamborghini. I drove the Lamborghini Huracan LP 610-4 on a racetrack, in the mountains, and along southern coast of Spain. It felt like the king of the car jungle in all of those places, sucking the eyeballs of observers nearly out of their heads as it drove by, and almost melting my brain with its cocktail of speed and grip and intense communication. It feels a little easy to say that the one new supercar I drove this year was also my favorite, but the fact is that the Huracan is one of the finest cars I've driven during my career, let alone 2014. Judge me if you must. – Seyth Miersma Senior Editor Rolls-Royce Wraith There are a couple of ways to look at the question, "What's the best car you drove this year?" In terms of what was so good I'd go out and buy one tomorrow, that'd be my all-time sweetheart, the Volkswagen GTI. Or if I'm just talking about sheer cool-factor, maybe something like the Galpin GTR1, BMW i8, or Mercedes-Benz G63 AMG. But instead, I'm going to write about the sheer opulence of being the best of the best. The hand-crafted, holier-than-thou, shut-your-mouth-when-I'm-talking-to-you supremacy. I'm picking the Rolls-Royce Wraith. I drove the Wraith for a week in April, and was really, really impressed. This car does everything, perfectly.

Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.
