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".

Watch these Dodge Demons explode on a Texas drag strip

The Dodge Challenger SRT Demon is extremely quick. It can hit 60 mph from a dead stop in less time than it takes to read this sentence thanks to its supercharged 6.2-liter V8. That engine makes up to 840 horsepower and 770 pound-feet of torque, depending on what octane is running through the fuel lines. That's a ton of power going solely to the rear wheels. So much so that Dodge developed a number of features and a new set of tires specifically for the car. In our time with the Demon, the car took abuse run after run on a drag strip without skipping a beat, but it seems some actual owners aren't quite so lucky. Just take a look at what happened to a few of these cars. You can see the whole car shake and jitter right as the whole rear explodes in front of the tree. It seems the initial shock from the launch — the most taxing bit of any drag run — is what kills the differentials. Catastrophic failure is rarely pretty, but it is neat to see the whole thing occur in slow motion. Three more cars — four stock and one modified in total — suffered similar fates. Not a great look for Dodge or SRT. According to The Drive, a private drag event in Texas drew a number of Demon owners all trying to beat NHRA NHRA Top Fuel racer Leah Pritchett's time in her personal Dodge Demon — 42 stock Demons attended along with five modified cars. While no one managed to match her 9.65-second quarter-mile run, a few owners did dip below 10 seconds. Now, there are a few of caveats we must address. First, with any modified car, you run the risk of breaking something, even with a car that's set up from stock specifically for drag strips. Even a set of tires like the Mickey Thompsons shown in the video above can have an effect on driveline components. Horsepower may be king, but it's torque that's the rear killer. All that torque sends a shock through the car. Adding even more with aftermarket parts increases the risk of something failing. The modified car was apparently pushing out about 1,000 horsepower. That said, four of the five vehicles were stock, so any extra power or torque should theoretically be a non-factor. The drag strip's surface was maintained by a company called Mass Traction. FCA used Mass Traction during the Demon's development, so that too should be a non-factor in the part's failure. It's unclear what exactly caused the failures, though The Drive reports that FCA officials are investigating the matter. Related Video: This content is hosted by a third party.

Ward's announces 10 Best Engines 2015

Ward's Auto has named its 10 Best Engines for 2015, covering a range of powerplants from fuel-sippers to fire-breathers. As with past years, forced-induction reigns supreme, with seven of the ten engines featuring a turbo or supercharger. This year is slightly different, though, as two of the seven blown engines are turbocharged three-cylinder mills, from the Ford Fiesta and Mini Cooper. They're joined by the 2.0-liter turbo four from the Volvo S60, the 1.8-liter turbo four from the Volkswagen Jetta and the 2.0-liter boxer from the Subaru WRX. BMW and Chrysler were the only marques to be named to this year's list twice, with the electric motor from the i3 joining the Mini's three-pot, and the 3.0-liter turbodiesel V6 in the Ram 1500 and Jeep Grand Cherokee repping the diesel crowd, alongside a certain supercharged monster. Hyundai also took a prize with a zero-emissions powertrain, with the Tucson FCV's 100-kilowatt fuel cell making the list (apparently Ward's is quite generous with what it deems an "engine"). Rounding out the list are two Autoblog favorites, each displacing 6.2 liters, but producing their power very differently. On the one hand, Chevrolet's overhead-valve, 455-horsepower V8, found in the Corvette, makes its power the old fashioned way. And in the other corner, we have one of the most exciting engines of the year – the 707-hp, 6.2-liter, supercharged Hellcat V8, featured so prominently in the Dodge Challenger and Charger SRT Hellcat. "We spend a lot of time reading the powertrain tea leaves throughout the auto industry, and we're proud that this year's list is a microcosm of all the latest innovation coming from automakers," said Ward's Editor-in-Chief Drew Winter in a statement. "It's not just a list for enthusiasts or for environmentalists," he says. "There's something for every vehicle shopper and every budget. All the powertrains on this list deliver a first-rate driving experience," Winter added. Scroll down for the full list from Ward's, and let us know which engines you think belong and which should have been included in this year's rankings.
