The EPA has alleged that FCA installed undisclosed emissions software in about 100k Ram and Jeep diesel models [UPDATE]

Update: The text has been updated with official information from the EPA given in a press release and a conference call. Although an initial report from Reuters said the EPA will accuse Ram and Jeep of using emissions defeat devices today, that isn't quite the case. In a press release and a conference call, the EPA stated that the notice of violation sent to FCA is for the installation of eight undisclosed auxiliary emissions control devices on 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models with the 3.0-liter turbodiesel V6. The violation applies to about 104,000 vehicles in total. The agency also explained that auxiliary emissions controls on vehicles are not necessarily illegal, but installing them without disclosing them to the EPA when having the vehicle certified is. Though this initial notice of violation is for installing undisclosed software, the EPA may soon also classify these emissions devices as defeat devices, as it did with the software Volkswagen used. Depending on the outcome of the investigation, there could be fines of up nearly $45,000 per vehicle involved in the notice of violation. The agency revealed that the software alters how the emissions system performs in certain situations. In controlled testing, the vehicles are compliant, but in conditions such as high speed operation, the EPA found the vehicles would produce much higher levels of NOx emissions. The EPA is continuing to investigate, and is waiting for FCA to explain why these emissions control devices are not cheating or defeat devices. In an official statement, FCA stated it is looking forward to explaining that the software does not constitute a defeat device, and has also proposed software updates to achieve compliance. During the conference call, EPA representatives also noted that the vehicles are still safe and legal to be driven, and that owners do not need to take any action yet regarding their cars. It should be noted there is no stop-sale on current models at this time. Additionally, 2017 versions of the 3.0-liter diesel FCA vehicles have not been emissions certified yet.

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
