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".

2016 Dodge Viper ACR is ready to take a bite out of the Corvette Z06 [w/video]

The Dodge Viper ACR is back, and as Fiat Chrysler Automobiles tells it, it's the most venomous breed ever born. Before you get too excited, the 8.4-liter V10 produces 645 horsepower; five more than the standard Viper and five less than the supercharged Chevrolet Corvette Z06. It's unclear why Dodge didn't extract more from the huge engine, although we somehow imagine that certain people in Maranello, Italy had a say in the matter. Instead of blessing the ACR variant with bunches of extra output, Dodge instead turned to an aggressive aerodynamics package that it claims delivers nearly a ton of downforce at the Viper's maximum speed of 177 miles per hour. The total aero package includes an adjustable, twin-element, carbon-fiber rear wing, carbon-fiber diffuser, an extendable front splitter, and dive planes. Those big louvers on the hood? Yeah, they're removable, too. The "race-tuned" suspension uses coil-over Bilstein shocks that offer ten different settings and up to three inches of height adjustment. Kumho Ecsta V720 tires were built specifically for the Viper ACR, and come in 355/30 in back and 295/25 in front, with 19-inch wheels at all four corners. Along with the aero improvements, Dodge is claiming the Viper can pull a race-car-like 1.5Gs in higher-speed turns. Carbon-ceramic brakes with six-piston calipers add the stopping power that's greater or equal to the ACR's cornering performance. Dodge was also keen to reduce weight, taking some rather dramatic measures in the effort. The stereo has just three speakers, while the electric function was removed from the seats. Even the carpet has been replaced with a "lightweight" alternative. Finally, Dodge is offering up the innovative 1 of 1 customization it pioneered with the Viper GT earlier this year. That means that not only can you get the fastest Viper ever built, but it'll be entirely your own when you take delivery.

2016 Dodge Viper ACR racks up lap records

With 645 horsepower and an adjustable spoiler nearly six feet wide, the 2016 Dodge Viper ACR would look at home on the runways of most any airport, air base, or aircraft carrier in the world. But it's not built for the runway. It's built for the race track. And it has positively mastered them one after another. In fact, the new Viper ACR has not only beat the lap times of its own predecessor as it set out to, but took the production-car lap record at 13 tracks across the country. The endeavor started out at the Inde Motorsport Ranch in Arizona, where development engineer Chris "The Wolf" Winkler set a lap time of 1:33.75 on the Configuration 4 track to beat every other street-legal vehicle to ever lap the circuit. Then it was off to Buttonwillow, the MotorSport Ranch (in Cresson, TX), Big Willow, VIR, Grattan, Pittsburg, GingerMan, the Motown Mile, Nelson Ledges, Waterford Hills, and Road Atlanta. And with the new American Club Racer, Dodge took the lap record at each and every one. The journey culminated just days ago at Laguna Seca, where track expert Randy Pobst climbed into the Viper ACR and set a lap time of 1:28.65. That's 5.27 seconds faster than the previous ACR's time, and 1.24 seconds faster than the Porsche 918 Spyder that held the record until now. The sum total is a bragging-rights sheet of lap records set at 13 tracks across these United States. And you don't have to take Dodge's word on that. The records have been certified by the Sports Car Club of America (SCCA), cementing the ACR's place in the record books. Nice work if you can get it, and you can scope it out in the video above and press release below.
