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".

2020 Colorado Winter Driver's Notes | Behind the Wheel S02 // E12

2020 Mercedes-AMG GLC 63 I’ve had bad luck with SUVs this winter. Especially performance ones. First, I got a 2019 Range Rover Sport SVR delivered on summers right as two feet of snow fell, rendering it undriveable. Then, coronavirus cancelled Easter Jeep Safari as well as my trip out to Moab in the 2020 Jeep Wrangler Rubicon Diesel. Thankfully, when this 469 horsepower luxury mall crawler was dropped off, the sun shone down and the snow (mostly) held off.  The first thing that I noticed was there were a few blank buttons throughout the cabin, something that you may see in an entry model vehicle, but IÂ’m not accustomed to seeing in an AMG. Not a great look for a vehicle with an $80,000 price tag. Thankfully that was where the disappointment ended. As soon as you press the start button, the engine fires up and the exhaust note is incredible. Hopping on the highway ramp near my house, I floored it, and the biturbo V8 had me pressed back into the driver's seat, and this wasnÂ’t even the S version that our staff drove last year. Inside and out, the GLC 63 was everything youÂ’d expect from Mercedes. The interior was immaculate, and while the infotainment wheel and touch pad may take some getting used to for someone who isnÂ’t familiar, by now I have it down so that I can use it without looking. And while the V8 left me smiling ear to ear, I was most impressed by the amount of useable interior space there is. I happened to be moving at the time of this review and while all of my large furniture was shoved into the back of a moving van, I was able to fit almost everything else in the back of the GLC. 2019 and 2020 Fiat 500X Trekking ItÂ’s hard to say goodbye to an AMG and then turn around and be excited when a Fiat 500X pulls in your driveway (I know, I know, automotive journalist problems). That being said, when the red Fiat pulled up, I found myself admiring it. I am very familiar with the 500X. Back in 2016 Autoblog had one for a year as our long term test vehicle. I drove that car everywhere, multiple trips up north in Michigan, and even tracked it at Gingerman Raceway for a few laps before the brakes started smoking.  The 2019 model I had in my driveway and the 2020 model I drove in the snow up in the mountains feel very similar to that car. The interior is stylish and surprisingly roomy. The greenhouse is airy.

Jeep Wrangler 4xe's hybrid powertrain: Could it be headed to other FCA products?

On its own, the 2021 Jeep Wrangler 4xe plug-in hybrid is a big deal for the brand and the model line. It's the most powerful and most efficient Wrangler by significant margins, and it doesn't give up the off-road capability that makes the Wrangler so special. But another great thing about this hybrid powertrain is its potential to be transplanted into other FCA vehicles. Just to recap, the layout of the Wrangler's hybrid powertrain, front to back, is as follows: engine, clutch, electric motor, clutch, transmission. The engine is the same 2.0-liter turbocharged four-cylinder that's a standalone engine for the Wrangler. The transmission and electric motor are sort of one unit, with the motor and clutch replacing the torque converter of the transmission. And the transmission itself is the ubiquitous eight-speed ZF automatic gearbox. Its transmission code name is 8HP75PH. The ZF eight-speed is available in every FCA product with a longitudinally-mounted engine and rear-wheel drive or four-wheel drive, with variations in the amount of power and torque it can handle. Not only that, but the Ram 1500 and 2500 and the Jeep Wrangler and Gladiator all have powertrains that utilize the non-hybrid version of the 8HP75 transmission specifically. Even the gear ratios for that transmission as well as the 8HP70 used in the Jeep Grand Cherokee, Dodge Durango, Dodge Charger and Chrysler 300 are nearly identical to those in the 8HP75PH. And a Fiat-Chrysler representative confirmed that the transmission portion of the hybrid drivetrain is basically carry-over from the regular 8HP75. So a transplant could be a relatively simple process. As for which of these models would be the most likely to receive the hybrid powertrain first, the Jeep Gladiator and Ram 1500 would seem like good bets, since they likely have the most similar transmissions, and the Gladiator in particular because of its closely-related underpinnings to the Wrangler. Both are also highly profitable trucks that sell well and could justify the development costs of adapting another powertrain. And in the case of the Ram, there's the impending F-150 hybrid to think about. Although Ram isn't going after a fully electric model, a PHEV could be a nice middle ground. A potential limiting factor would be whether the hybrid powertrain would be sufficiently robust to handle heavy payload and towing demands, particularly over longer periods.
