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".

Junkyard Gem: 1991 Dodge Stealth R/T

Chrysler's relationship with Mitsubishi goes back to the early 1970s, when the first Mitsubishi Colt Galants arrived from Japan with Dodge Colt badging. Plenty of Mitsubishi-built Arrows and Ram 50s and Challengers followed, and the joint Chrysler-Mitsubishi plant in Illinois began building cars in 1988. By the 1990s, you could find Mitsubishi DNA throughout the American Chrysler family, and the Mitsubishi GTO was brought over to become the Dodge Stealth starting in 1991. Here's one of those first-year Stealths, now residing in a Colorado self-service boneyard. Four grades of Stealth were available here in 1991, with the R/T Turbo AWD at the very pinnacle. This car, a regular R/T, is one step down from that model but still a pretty quick machine for its time. MSRP was $25,155, or about $55,370 in 2022 dollars. The R/T got this naturally-aspirated DOHC 6G72 engine, displacing 3.0 liters and making 222 horsepower. If you got the turbocharged version in the R/T Turbo AWD (or the Mitsubishi 3000GT VR-4), power went up to 300 horses. The 3000GT (as the GTO was known here) was mechanically identical to this car but had slightly different styling. The GTO/3000GT/Stealth replaced the Mitsubishi Starion and its Chrysler/Dodge Conquest siblings, which were sold here from the 1983 through 1989 model years. The Starion was a rear-wheel-drive machine that competed for sales against the Toyota Supra and Nissan Z, while the Mitsubishi GTO was available with either front- or all-wheel-drive. As illustrated by this photo of the rear suspension, this car is a front-wheel-drive version. Americans loved automatic transmissions 30 years ago, nearly as much as we love them today, but this car has a proper five-on-the-floor manual. If you wanted the optional four-speed automatic, it cost 813 bucks ($1,790 today). The Stealth R/T AWD had a mandatory five-speed manual transmission. This car has been hit hard by junkyard shoppers and the ravages of time, but it was fairly luxurious when new. Air conditioning was standard equipment on the R/T, though not on the lesser Stealths. This car came close to 150,000 total miles, but fell a bit short of that milestone. The final year for the Dodge Stealth was 1996, though the Mitsubishi 3000GT remained available here through 1999. The Mitsubishi GTO held on through 2000 in its homeland. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Outhandles the Lotus Esprit!

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.
