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".

Fiat Chrysler's next-generation Uconnect is faster, built on Android

If you're a regular reader of Autoblog, you know that for a long time we've liked Fiat Chrysler's Uconnect infotainment system for its bright, clear, responsive touchscreen interface. Now, according to the company, it will be better than ever with Uconnect 5, the latest iteration of the system. It has upgraded hardware and a revamped graphic user interface (the stuff on the screen). Looking at sample screens shown above, there are characteristics shared with the old system, such as the time, status and shortcuts at the top and the menu icons at the bottom. In the middle, the major change is the addition of home screens that can be customized with favorite menus and readouts that are always available. Each of these home screens can have up to four functions and you can have five pages to flip through. The graphics themselves feature more legible fonts and updated icons. Each car brand will get its own set of icons, colors and textures to help create unique experiences. And while each Fiat Chrysler product will be able to have Uconnect, including Alfa Romeo that has until now lacked Uconnect, each brand has the ability to make small tweaks including the screen orientation. The system will support displays in landscape, portrait or square, so different brands may choose different shapes. Powering Uconnect 5 is a processor Fiat Chrysler says is six times more powerful than what's in current systems. It features 6 gigabytes of RAM and 64 gigabytes of internal storage. The processor also supports screens as large as 12.3 inches with as many as 15 million pixels, or nearly twice that of a 4K resolution TV. The system can display information on up to four screens, too. Uconnect 5's firmware is built on Google's Android operating system, joining a few other automakers in using Android as a base for their infotainment systems. Uconnect 5 brings with it a number of new features. It brings full Alexa integration, so you can use it just like you do at home, provided you have a data plan for the car. Apple CarPlay and Android Auto continue to be standard, but now they can be used wirelessly. You can also now connect two phones via Bluetooth wirelessly so you can access content from both. Navigation gets real time information and updates from TomTom. Users can create five profiles with unique climate, radio and instrument settings, plus one for a valet.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
