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".

Corvette Z06 and Viper TA square off at the strip

There are many long-standing grudge matches among automobiles: 911 vs GT-R, Mustang vs Camaro, Ferrari vs Lamborghini... but as far as high-end American metal goes, it doesn't get much more legendary than Viper vs 'Vette. So after Chevy released the new Corvette Z06, we knew it was only a matter of time before it would have to square off against the Viper TA. And what better place to pit these two parallel pillars of American performance than on the drag strip? Fortunately that's just what we have here. In one corner, the 2014 Dodge Viper TA, with its 8.4-liter V10 pumping out 640 horsepower and 600 pound-feet of torque. In the other, the 2015 Chevrolet Corvette Z06, the supercharger on its 6.2-liter V8 more than making up for the discrepancy in displacement and cylinder count to produce 650 hp and just as much torque. But numbers don't tell the whole story, so watch the video clip to see which reaches the end of the quarter-mile first.

Inner Demon revealed: 840 hp and other jaw-dropping details

After months of teasers, rumors, cryptic messages, and veiled hints, the 2018 Dodge Challenger SRT Demon is finally here, and it's as wonderfully insane as we hoped it would be. Finally we know the facts and figures that Dodge has been hinting at for so long. 840 horsepower. 770 lb-ft of torque. 2.3 seconds to 60 mph. A quarter-mile run of 9.65 @ 140 mph. While pricing hasn't been announced, Dodge is trying to keep it under $100,000. That horsepower figure makes this the most powerful production V8 ever. With those 0-60 and quarter-mile times, it's also NHRA certified as the quickest production car ever. Someone with the means needs to line a Demon up against a Tesla Model S P100D. All that power and all of the Demon's trick launching software and hardware will throw a driver back against their seat with 1.8 Gs. Drivers will be seeing a bit of sky, as the Demon is the first production car to pull a wheelie from a dead stop. Yes, this is all totally and 100 percent street legal. View 48 Photos In order to make all this power, the red-painted supercharged 6.2-liter Hemi V8 has been significantly improved over the Hellcat. It's equipped with a larger 2.7-liter supercharger that turns the boost up to 14.5 psi, redlines at 6,500, and has what Dodge is calling SRT Power Chiller, a system that uses the air conditioning to cool the air coming in through the new Air Grabber hood scoop. In order to keep your engine running time and time again, there is an after-run cooler than cools the supercharger after the car is shut off. The pistons and connecting rods have been strengthened to deal with the higher load. In order to feed enough juice into the engine, the Demon uses dual fuel pumps. We assume that a decent EPA rating wasn't on the top of the engineer's list. Oh, and the Demon can run on 100-octane with the press of a button. With the traditional SRT black and red keys, the Demon actually has three horsepower ratings: 500 with the black key, 808 with the red key, and the full 840 with the red key and 100-octane fuel. Don't worry, even if you have the black key, the Demon will drop the 1/4 mile in 11.59 seconds, still quicker than almost anything around. Most of the rest you already know from the seemingly endless teasers. The Demon wears lightweight wheels with sticky 315/40R18 Nitto drag radials at all four corners.
