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 Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues. Hardware: 35 percent lower rate front springs/28 percent lower rate rear springs 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar Drag-tuned Bilstein Adaptive Damping Shocks Software: Rear = F/F and Front = F/S F/F – F/S maintained @ wide open throttle (WOT) F/F – F/F < WOT Traction control disabled/ESC maintained Result: 13.5=575@500 Related Video: This content is hosted by a third party.

Stellantis won't race to split electric vehicles from fossil fuel cars

MILAN - Stellantis is not considering splitting its electric vehicle (EV) business from its legacy combustion engine operation, its finance chief said on Thursday, as the carmaker presented above-expectation revenue data for the first quarter. Chief Financial Officer Richard Palmer told analysts he did not see huge benefits in the kind of separations pursued by rivals such as France's Renault and U.S. Ford. "We need to manage the company and the assets we have through this transition," he said. "There are benefits to having the cash flow being generated by the internal combustion business for the investments we need to make." Palmer said the group, formed by a merger last year of Fiat Chrysler and Peugeot maker PSA, was not averse to considering adjusting its structure "but we aren't anticipating any big changes." Palmer's comments came after the world's fourth largest carmaker said its net revenue rose 12% to 41.5 billion euros ($44.1 billion) in the January-March period, as strong pricing and the type of vehicles sold helped offset the impact of the semiconductor shortage on volumes. That topped analyst expectations of 36.9 billion euros, according to a Reuters poll. Milan-listed shares were up 0.5% by 1415 GMT, in line with Italy's blue-chip index. The impact of the chip crunch was evident in the decline in shipment figures which fell 12% in the quarter to 1.374 million vehicles. It was a similar story for Germany's BMW which posted higher revenues on Thursday and a decline in car sales. Riding the Recovery Stellantis, whose brands also include Citroen, Jeep and Maserati, confirmed its 2022 forecasts for a double-digit adjusted operating income margin, after 11.8% last year, and a positive cash-flow despite supply and inflationary headwinds. Morgan Stanley analysts said after the results that Stellantis had better management than many peers and benefited from its significant exposure to a stronger U.S. economy and a European recovery from the COVID-19 pandemic. They also said it was less affected by a slowing Chinese economy. Palmer said it was important for the group to maintain double-digit margins and keep delivering positive cash flows. "A 12% increase in revenue with a 12% decrease in volumes indicates a very strong performance on price and mix, which augurs well for our margin performance," he said. He said semiconductor supply problems were expected to ease this year with continued improvements in 2023.
