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".

Dodge launches 1 of 1 Viper configurator

Get comfortable because you might be spending a good chunk of time in front of the computer on this. The configurator for the 2015 Dodge Viper GTC 1 of 1 is now online, and it's a ton of fun to play around with. Mechanically, the GTC is just like every current Viper with a 645-horsepower, 8.4-liter V10. But for the special editions Dodge lets buyers tinker with practically everything aesthetic thing. For the exterior alone, the choices include some 8,000 available body colors, two stripe styles in innumerable shades, two hood designs and various brake caliper hues. Plus, there are 16 upholstery colors inside, and options like red seat belts and carbon fiber trim. Dodge reckons there are over 25 million possible combinations, and the models are available to customers on a first-come-first serve basis for each model year. Although, two people wanting identical cars seems pretty unlikely. The configurator is a beauty too. It makes all of these myriad options extremely easy to pick from, and there are even four resolution settings to see your creation in the best possible way. Prices for the GTC start at $94,995 and deliveries are set to start in the second quarter of the year. Although, even if you have no intention of buying one, specifying these custom coupes is still highly entertaining.
