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".

Performance doesn't matter anymore, it's all about the feel

We've just had a week of supercars and high-end EVs revealed. Many of them boast outrageous performance specs. There were multiple vehicles with horsepower in the four-figure range, and not just sports cars, but SUVs with 0-60 mph times under 3.5 seconds. And it's not just a rarified set of supercar builders, comparatively small tuners are also building this stuff. Going fast is easy nowadays and getting easier. So what will distinguish the greats from the wannabes? It's all about how a car feels. This may seem obvious. "Of course it matters that a car should have good steering feel and a playful chassis!" you say. "Why are you being paid for this stuff?" But a lot of automakers have missed the memo. This past week I spent some time in a BMW M4 Competition convertible, and it's a perfect example of prioritizing performance over experience. It boggles my mind how a company can create such dead and disconnected steering; the weight never changes, there's no feel whatsoever. The chassis is inflappable, but to a fault, because it doesn't feel like anything you're doing is difficult or exciting. The car is astoundingly fast and capable, but it feels less like driving a car and more like tapping in a heading on the Enterprise-D. I also happened to drive something of comparable performance that was much more enjoyable: a Mercedes-AMG GT. It was a basic model with the Stealth Edition blackout package, and even though it had a twin-turbo V8 instead of a six-cylinder, it only made 20 more horsepower. The power wasn't the big differentiator, it was (say it with me) the feel. While not the best example, the steering builds resistance as you dial in lock, giving you a better idea of what's happening up front. Pulses and vibrations come back to you as you move over bumpy pavement in corners. The chassis isn't quite as buttoned down, either, providing a little bit of body roll that tells you you're pushing it. It's also easier to feel when the car is wanting to understeer or oversteer, and how your throttle and steering inputs are affecting it. The whole thing is much more involving, exciting and fun. 2021 Mercedes-AMG GT Stealth Edition View 8 Photos That's also to say nothing of the Merc's sounds. That V8 is maybe not the best sounding engine, but its urgent churn through the opened-up exhaust gets your heart racing. It also seems like it's vibrating the whole cabin, so you feel it as much as you hear it.
