2017 Ram Power Wagon

Impassioned calls for Ram to drop the Cummins 6.7-liter inline-six diesel into the Power Wagon are not new, nor is Ram’s response. I recently spoke with Jeff Johnson, Ram’s brand manager for heavy duty trucks, who unequivocally stated, “Ram has no plans to offer the Power Wagon with a diesel.”

Johnson pointed to the increased weight of the 6.7-liter Cummins versus the 6.4-liter Hemi V8 presently under Power Wagon hoods, as well as the difficulty of engineering the front end to accommodate both the diesel’s cooling requirements and the truck’s standard 12,000-pound winch.

We accept the reality of these challenges. But could Ram overcome them?

Absolutely, though Ram’s engineers have determined the cost outweighs the benefits. Even setting my enthusiast hat aside, I am not confident that bypassing this opportunity altogether is the best choice for Ram. Read More >

2017 Audi Q7 blue front

Audi’s European introduction of the beastly SQ7 SUV caused no shortage of speculation last year. Even as Volkswagen Group’s emissions scandal raged, many hoped the raw power of the SQ7’s cutting-edge diesel engine would be enough to compel Audi to bring the model stateside.

Waiting followed. Then, even more waiting. Audi told excited journos it hadn’t greenlit the model for a U.S. launch, despite its very marketable 435 horsepower and 664 lb-ft of torque — power made possible by 4.0 liters of displacement, two turbochargers and a lightning-quick electric supercharger.

Late last year, Volkswagen CEO Herbert Diess put the chill on expectations, telling everyone it wasn’t likely they’d ever see a new diesel Volkswagen product in the United States. This, despite current advancements in diesel technology. It now seems any hesitation the automaker might have felt about that proclamation has evaporated.

Diesels? Dream on. Read More >

Ram and Jeep fans looking to get into a new 1500 or Grand Cherokee with the highest possible fuel economy picked the wrong year to embark on their search. While owners of 2014-2016 Ram and Grand Cherokee EcoDiesel models wonder whether their vehicles are polluting as the EPA claims, Fiat Chrysler Automobiles’ 2017 EcoDiesels languish in legal limbo.

At first, the Environmental Protection Agency held up the certification of 2017 models as it slogged through a backlog of extra-stringent testing prompted by Volkswagen’s diesel emissions scandal. Then, in January, FCA’s hopes of getting 2017 EcoDiesels to dealers hit a brick wall. The automaker was accused of violating environmental regulations after the EPA discovered unannounced emissions control devices on the models — raising concerns of a possible VW-type defeat device scheme.

Then came a lawsuit filed by the U.S. Department of Justice. So, when can diesel fans get their hands on a light-duty FCA oil burner? It could be a while. Read More >

The university that sparked the emissions wildfire under Volkswagen has turned its testing equipment on Fiat Chrysler’s 3.0-liter EcoDiesel vehicles. The results aren’t pretty, especially for those with diminished lung capacity.

West Virginia University researchers who tested tailpipe emissions in real-world driving conditions claim the Ram 1500 and Jeep Grand Cherokee EcoDiesels, singled out by the Environmental Protection Agency in January for excess pollution and unauthorized emission control devices, are indeed quite harmful to air quality. The university plans to detail its findings in a report to be published within weeks.

FCA, which proved unable to sidestep the EPA’s wrath or a lawsuit from the U.S. Department of Justice, has spoken out against the university’s methods. Read More >

It’s hard not to imagine Volkswagen as a tempestuous child, prone to mischief and currently on a “time out” after getting caught lobbing spitballs in class. The thought softens the reality of a massive corporate deception that polluted the air and led to tens of billions of dollars in penalties.

As it turns out, serving as Volkswagen’s nanny is exhaustive work. After the U.S. government ordered a monitor to keep an eye on the automaker as part of its wildly expensive settlement, the monitor feels the need to triple his staff. Read More >

A problem faced by many Volkswagen TDI owners over the past several years has become a thornier issue ever since the company’s diesel debacle.

North of the border, several owners of 2.0-liter diesel models have turned to the media after high-pressure fuel pump failures turned their vehicles into Teutonic paperweights. The problem facing the owners was unique: to have the automaker buy back their vehicles as part of the emissions scandal settlement, the cars needed to be in running order. No longer covered by warranty, the cost to repair a fuel system contaminated by metal fragments was potentially more than the owners would receive in the buyback.

The burning anger is enough to melt snow. Read More >

Suing automakers over diesel emissions violations is quickly on its way to becoming passé.

Since Volkswagen admitted to installing software that circumvented pollution laws, regulators have been on the hunt for their next big target. While it might make their efforts seem like a bit of a witch hunt, there’s good reason to be on the lookout. Studies have shown diesel emission levels are often much higher than analysts expected, with experts attributing the results to the high probability that other automakers are skirting regulatory guidelines — likely by way of defeat devices.

Daimler, Renault, and PSA Group are all being investigated in their home countries as FCA faces legal action within the United States.

General Motors is now being sued for allegedly installing defeat devices in its trucks to sidestep emissions tests, making it the sixth major manufacturer accused of diesel cheating since 2015. However, General Motors isn’t dabbling in gray areas, acting confused, or assuring the public it will get to the bottom of the accusations. It says the claims against it are flat out wrong.  Read More >

The U.S. Department of Justice has filed a civil lawsuit against Fiat Chrysler Automobiles, alleging the automaker violated the Clean Air Act.

At the root of the lawsuit is roughly 104,000 Ram 1500 and Jeep Grand Cherokee vehicles equipped with the 3.0-liter diesel V6, sold between 2014 and 2016. Earlier this year, the Environmental Protection Agency accused FCA of failing to disclose eight auxiliary emissions control devices during the certification process. The vehicle’s software allows for higher-than-permitted emissions at certain times.

Despite FCA’s protests — as well as attempts to head off a potential multi-billion-dollar fine — the parallels between this case and Volkswagen’s emissions saga are growing by the day. Read More >

The Environmental Protection Agency and California Air Resources Board will soon announce an approved fix for roughly 84,000 recalled Volkswagen diesels. As part of VW’s buyback program of cars equipped with emissions-cheating defeat devices, the soon-to-be-certified modification allows 2012-2014 Passat TDIs to operate within acceptable pollution guidelines.

Volkswagen has already designed fixes for the Generation 3 diesel 2.0-liter engines, providing vehicle owners the choice to keep and repair their car, or to have it bought back. Similar fixes in Europe have yielded complaints of reduced fuel economy, starting difficulties, trimmed power, weak acceleration, and even abnormal sounds. As usual, if you want to hold onto your TDI, you may be doing so at your own riskRead More >

After being forbidden from selling 2017 Ram 1500 and Jeep Grand Cherokee models equipped with the 3.0-liter diesel V6, Fiat Chrysler Automobiles is hoping for a little love from the Environmental Protection Agency.

The EPA suspended the certification process in January after discovering eight undeclared auxiliary emissions control devices on the EcoDiesel models. The existence of the software, installed in those vehicles since the 2014 model year, earned FCA a notice of violation of the Clean Air Act. Since then, the automaker has attempted to work with environmental regulators to smooth over the controversy, even as its mailbox filled with subpoenas from federal and state authorities.

Yesterday, we learned the Justice Department was readying a lawsuit against FCA. With the potential for billions of dollars in fines staring it in the face, FCA has whipped up a new application in the hopes of placating the EPA and selling some light-duty diesels. Read More >

General Motors seems to hope buyers of its upcoming diesel Chevrolet Cruze hatchback are interested in both fuel economy and tossing around their new purchases with reckless abandon.

When it goes on sale this fall, the 2018 Cruze diesel hatch will offer a standard six-speed manual transmission, as well as something you won’t find on its diesel sedan sibling — the RS Package. It looks like “fun diesel” is the new “clean diesel.” Read More >

The U.S. Justice Department is preparing itself for a lawsuit against Fiat Chrysler Automobiles over, you guessed it, diesel-burning engines. Cetane-rated fuel has been a broad target for governments lately, but the forthcoming FCA suit is less concerned with what you’re burning than with how you’re burning it.

Officials are concerned the automaker may have used a defeat device after the Environmental Protection Agency accused it of using software that allowed about 104,000 diesel vehicles to emit excess emissions. The models in question are 2014-2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0-liter diesel engines. Read More >

Earlier today, we mentioned Volvo was preparing to dump its diesel-burning engines because the EU is aggressively pursuing anti-diesel legislation. While it’s easy to accuse Europe of being fraught with fringe environmentalists, the truth is that the continent spent decades avoiding restrictions on diesel-burning passenger vehicles, sold loads of them, and has suddenly found itself with its green pants around its ankles.

In addition to hazy skies, air pollution isn’t exactly great for your health. A recent study published in Nature found diesel engines produced 5 million more tons of nitrogen oxide than previously estimated for 2015. The research focused on vehicles in Australia, Brazil, Canada, China, the European Union, India, Japan, Mexico, Russia, South Korea and the United States and uncovered that we’ve grossly overestimated the amount of good being done by our global regulatory efforts. Companies are practically guaranteed to be falsifying testing results while others are openly incapable of reaching government-enforced guidelines.

Who cares? It’s not like anyone is dying, right? Well, not exactly. Read More >

Volvo Cars is prepared to lower the curtain on diesel engines. Rising standards for nitrogen oxide emissions — and the cost associated with reducing them — has guided the automaker away from oil burners and into the loving arms of gasoline. “From today’s perspective, we will not develop any more new generation diesel engines,” CEO Hakan Samuelsson told Germany’s Frankfurter Allgemeine Zeitung.

That is not to suggest Volvo won’t get some serious mileage out of its last batch of diesels, though. The automaker has no plans to abandon the motors outright, suggesting it could march onward with its current lineup for at least a few more years. Diesels would also help Volvo meet corporate fuel economy targets while it gets new super-economical electric powerplants ready for market.  Read More >

Should you expect Ford Fusion levels of engine choice in the next-generation Jeep Wrangler? A new report claims yes, you should.

A source who claims connections at a Fiat Chrysler Automobiles plant has told Jalopnik the upcoming 2018 model will host six engines, but a rational take on the matter would suggest readers not get their hopes up — at least, not in the U.S. Read More >
