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".

Cruise Woodward Avenue with Autoblog's Dodge Challenger Hellcat

While Autoblog was consumed by coverage of the increasingly important Monterey Car Week last weekend, there was another big even going on. The Woodward Dream Cruise is significantly lighter in terms of news, but there's no denying that it's a far bigger, and far more egalitarian than what the wine-and-cheese crowd experience on the links at Pebble Beach. The Dream Cruise crams tens of thousands of cars and over a million spectators along a four-lane ribbon of asphalt between Ferndale and Pontiac, MI. What's remarkable aren't these numbers, though, so much as the distances they travel. Owners and admirers come from far and wide, across the United States and in some cases across the globe, to take in the spectacle. This year, local radio and television coverage featured fans that traveled from Japan, Australia, and Europe, just to take in the cruise. Of course, we realize that not everyone can make the pilgrimage to Woodward Avenue. With that fact in mind, we decided to bring a bit of the Dream Cruise to Autoblog with a time-lapse video of the cruise route. You can experience the good (a Lamborghini Gallardo, Chevrolet Chevelle, and Oldsmobile Cutlass 442), the bad (the traffic jams), and the ugly (no, your 2003 Ford Focus does not qualify as a classic, get the hell out of the cruiser lanes). So join us, as we turn off 8 Mile Road behind the wheel of our 2015 Dodge Challenger SRT Hellcat and run north, through Ferndale, Pleasant Ridge, Royal Oak, Huntington Woods, Berkley, Bloomfield Township, and Bloomfield Hills, before ending up on Wide Track Drive in Pontiac.

Watch Jay Leno drive an ex-highway patrol '61 Dodge Polara

The latest vehicle to swing by Jay Leno's Garage is a 1961 Dodge Polara. This one was used by the California Highway Patrol half a century ago, ordered specially by the state police instead of the Darts that were usually used by law-enforcement. After sitting out in the sun for a few decades, it recently underwent a comprehensive, ground-up restoration by the historians and craftsmen at the Automobile Club of Southern California. As you can see for yourself, the result of the restoration is really quite stunning. The ACSC apparently spared no expense, bringing the 413-cubic-inch V8 back up to working order, along with the emergency lighting, radio, certified speedometer... the works. In the process they even found the engine cranked out more than the factory quote of 325 horsepower, recording 332 hp and 406 pound-feet of torque on the dyno. The Polara CHP cruiser hadn't even been back out on the freeway since the restoration was finished. But after getting the full run-down from the guys responsible for its resuscitation, Jay wasted little time in bringing it back to its natural habitat.
