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 First Drive [w/video]

The Dodge Viper is not a comfortable car. Livable, yes. The interior is covered in fine materials. But you still climb over a hot door sill to enter the tiny cabin. And the frequency range of the engine's noises seem specifically designed to cause headaches. What happens, then, if you remove all pretense of civility from a Viper and add equipment solely aimed at improving lap times? You would have the 2016 Dodge Viper ACR. In terms of achieving its purpose, this car is a absolute success. In many ways it's also the most honest Viper of the current generation. Prices start at $121,990 (including $2,100 gas-guzzler tax and $1,995 destination), or $32,900 more than the least expensive Viper. In ACR trim, the Viper loses the under-carpet padding, 9 of 12 speakers plus amplifier, carpet and trim from the cargo area, and sound deadening in front of the rear wheel wells. The parts of the interior still covered add healthy amounts of Alcantara or optional carbon fiber. That weight loss is compensated by the addition of go-fast bits like the giant rear wing (or the larger "x-wing" on the Extreme Aero Package), 10-way adjustable Bilstein Motorsports shocks, Brembo carbon-ceramic brakes, a rear diffuser, and a front splitter. Total claimed curb weight is 3,392 pounds in Aero trim (standard ACR trim is 18 pounds lighter), which is within a few stone of the rest of the Viper lineup. The diffuser strakes and leading edge of the splitter are removable, made to be replaced after rubbing on track tarmac and make street driving slightly more practical. Not that you'd want to drive the ACR on the street, with the lack of noise insulation and spring rates twice as stiff as the Viper TA, but it is street-legal. Dodge claims the DOT-approved Kumho Ecsta V720 tires on the ACR allow faster lap times than some race compound tires. Our test was limited to on-track shenanigans at Virginia International Raceway. Which is fitting because we wouldn't have anything good to say about driving the car on the street. The ACR is, essentially, a race car sold in the showroom, although with the Viper's 1 of 1 customization program, your custom build can include as many creature comforts as you like. Lined up in pit lane at VIR, the Viper ACRs for our evaluation blur the air with heat shimmer. All of the test cars have air conditioning, but that shuts off at full throttle with a six-second reset.

Playing in the snow | 2017 Dodge Challenger GT First Drive

The previous day was miserable. An icy rain fell over Portland, Maine, coating the pavement and making even walking a chore. Driving a muscle car like the Dodge Challenger seems ill-advised. But this is exactly the weather Dodge hoped for, because we're here to test the new all-wheel-drive 2017 Challenger GT. The morning of our test drive dawns sunny and cold. The remnants of a late January nor'easter now past, we nonetheless steel ourselves for a day of unruly roads. Stepping into an inch of slush, we open the huge door, climb inside, and nestle into the heavily bolstered driver's seat. Immediately comfortable, we know the Challenger well. It's an old friend. Late in life, it's finally finding stability. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Heading onto the Maine turnpike, we're struck by the Challenger's poise. All-wheel drive civilizes the coupe's brutish nature. We confidently navigate the first on-ramp – still wet from the storm – and merge onto the highway. A rear-wheel-drive car would come unsettled here, yet this Challenger's 19-inch wheels wrapped in all-season Michelin rubber are not disturbed. At the very least, the specter of tire spin would have made us overcautious. All-wheel drive doesn't morph the Challenger into a Subaru Outback, but it does make the Mopar a realistic year-round option for buyers north of the Mason-Dixon line. Dodge arrived at this conclusion after some introspection. The Challenger and its sibling the Charger sedan are usually cross-shopped with each other, and design is often the deciding factor. With Charger AWD sales remaining strong (in 17 Northern states at least 50 percent of Chargers are sold with the system), not offering an all-wheel Challenger leaves money on the table. Ben Lyon, Challenger brand manager, says the common refrain was, "I would have bought a Challenger, or I would have bought a two-door muscle coupe, if it was available with all-wheel drive." View 50 Photos Naturally, the Dodges share an AWD system, which has an active transfer case and the ability to disengage the front axle, making the Challenger a rear-wheel-drive car in certain conditions to help save fuel. Ambient temperature, wheel slip, Sport mode, passing situations, and the driver's behavior can trigger the all-wheel capability.
