German prosecutors have incorporated Continental into a probe aimed at determining whether Volkswagen Group cheated on emissions testing. While confessing to the crime in the United States years earlier is a fairly good indication of corporate guilt, Germany wants to make extra sure VW was in the wrong and has branched out its investigation to include suppliers that may have played a role.

On Wednesday, the automaker acknowledged it had been subjected to yet another probe after investigators arrived to comb through its offices. The same treatment was given to supplier Continental, which is suspected of having some sort of involvement in a scandal the automotive industry can’t quite seem to move on from.  (Read More…)

Compared to the clattery, soot-spewing 350 diesel that helped sink General Motors’ reputation in the 1980s, the 3.0-liter Duramax inline-six introduced in the automaker’s full-size pickups late last year is a refined affair. It’s also making something of a reputation for itself, drawing buyers to the company’s truck-only brand who might otherwise have looked elsewhere in the industry for a pickup.

GMC now says it’s targeting a surprising take rate for the Flint-built engine. (Read More…)

The California Air Resource Board (CARB) just passed a mandate that will require manufacturers of big rigs, heavy duty pickups, and some construction equipment to adhere to new zero-emission quotas and a carbon-credit system.

As all-electric 18-wheelers are in short supply, California wants to wait a few years to put the new rules into play. Still, it’s eager to get the ball rolling so it can start replacing diesel-driven transport with something from the battery-electric section. It also gives the state another opportunity to pat itself on the back despite not having any clue whether or not the strategy is economically sustainable. Even with battery technology moving at a fair clip, there’s a lot of engineering left to be done before these types of vehicles can become commonplace.  (Read More…)

Volkswagen’s emission-related malfeasance was promptly identified and dealt with in the United States. The company was accused of using suspect software to game testing scores on diesel-equipped models in 2015. By October of 2016, VW was on the hook for a $15.6 billion financial penalty, in addition to mandatory fixes or buybacks on affected vehicles.

Things progressed differently on the European front. Germany has subjected the manufacturer to numerous investigations, ultimately deciding to fine the firm $1.18 billion in 2018 and enact widespread recalls. Civil suits have largely focused on VW’s legal representatives denying the software had any ill intent, claiming it was simply code that mistakenly allowed the cars to become non-compliant with regulatory limits. This didn’t fly, however, with a gigantic UK lawsuit finding the automaker guilty of intentionally misleading customers in April.

This week, VW lost another important legal battle in Germany when the Bundesgerichtshof found it guilty of cheating on emissions testing years earlier. The Federal Court of Justice in Karlsruhe decided disenfranchised diesel van owner Herbert Gilbert was entitled to a €28,000 payday, setting a precedent for thousands of other claimants seeking revenge.  (Read More…)

Despite the switch to low-sulfur fuel and ever more stringent emissions regulations around the world, compression ignition technology still gets a bad rap, tarnishing the remaining crop of diesel engine offerings despite their fuel economy advantages.

In the world of heavy duty pickups and large commercial vehicles, it’s a case of diesel or what else? Electric motors powered by battery banks the size of a refrigerator warehouse? Gotta use what works.

Diesel engine maker Cummins sees plenty of life left in the technology, and believes better is possible. If gasoline engines can shut down cylinders at will to conserve fuel, why not oil burners? (Read More…)

While it remains to be seen whether the revamped 2021 Cadillac Escalade enters production on schedule this summer, other details about General Motors’s loftiest SUV have begun leaking out.

One item concerns the vehicle’s price, while the other tidbit might interest those who have a difficult time separating their eco-consciousness from their economic reality. (Read More…)

It seems readers gravitated to Chris’ recent review of the Silverado 1500 Duramax. Indeed, I was curious to see just how well General Motors’ new 3.0-liter inline-six diesel handled day to day life and, more importantly, how well it performed at the pumps.

Looks like the pickup’s fuel economy was worthy of note. With each full-size member of the Detroit Three now fielding an oil burner, light-duty diesel fuel economy has become another arena in which to do battle. Of course, the industry has always used fuel economy as a yardstick (despite it not being much of a selling point at various times in history), and as always, the buyer’s mileage will vary, regardless of what EPA figures appear in the window sticker.

Have you ever been pleasantly surprised? (Read More…)

2020 Chevrolet Silverado front quarter

Somebody had to ruin the party. Five years ago the Dieselgate scandal broke, and automakers everywhere slowed down the development of their own oil-burning engines for the U.S. market. Until that point, many automakers were looking at bringing “clean” diesel tech from Europe to the U.S.

Of course, compression-ignition engines have been quite common in the truck market – though generally confined to the heavy-duty, three-quarter-ton and larger models for many years. In the last couple of years, each member of the Detroit Three has revealed a smaller diesel for their half-ton pickups. This 2020 Chevrolet Silverado 1500 is powered by a Duramax 3.0-liter inline six, backed up by a 10-speed automatic.

I’m not sure I’ve ever fallen so hard for a powertrain.

The hosts of the Discovery Channel’s Diesel Brothers have been fined $851,451 for selling modified pickups that violate Utah law and the federally recognized Clean Air Act.

U.S. District Court Judge Robert Shelby also said the plaintiffs, Utah Physicians for a Healthy Environment, could submit their attorney fees for the defendants to pay. Cole Cannon, lawyer to the stars, has said the plaintiffs’ attorneys previously told the judge they were seeking $1.2 million.

Friday’s court documents stipulate that David “Heavy D” Sparks, Joshua Stuart, Keaton Hoskins, and “Diesel Dave” Kiley pay $761,451 to the U.S. government with the remaining $90,000 going to Davis County in Utah. The group has already been found guilty of removing particulate filters and exhaust recirculation systems on the cars used for the television program. The only genuine surprise was the sizable fine —  as well as some court-appointed rules that will probably make the show less exciting to watch.  (Read More…)

2019 Mazda Skyactiv D CX-5 Diesel - Image: MazdaWhen it was rumors and innuendo, when it was delayed, when it was confirmed but unattainable, when it was launched, when it was actually under the hood of a vehicle we could drive on this continent, we’ve covered the story of Mazda’s diesel engine.

It’s a 2.2-liter turbocharged four-cylinder with a measly 168 horsepower but a stirring 290 lb-ft of stump-pulling torque. It resides not in the Mazda 6 for which it was originally intended but rather the highly acclaimed Mazda CX-5. It’s available only in the CX-5’s top-spec Signature trim, and only then at a $4,110 premium that drives the price up to an eye-watering $41,000. Its fuel economy gains are so minimal that the economic case for the CX-5 diesel is nonexistent.

And after one model year and just enough demand to help (in some small way) propel the CX-5 to yet another record sales year, the Mazda CX-5 diesel is missing. Truant. Unaccounted for.

Moreover, there’s no timetable for the CX-5 diesel’s return. (Read More…)

The road to America is often a long one, and the 2.2-liter diesel four-cylinder that finally set up shop in the Mazda CX-5 last year took a Donner Party-like detour after leaving Japan.

The Skyactiv-D engine was over half a decade late in arriving on these shores, and when it finally did — cleared by the EPA after certain modifications — journalists were underwhelmed by its power and economy. Now, it’s the midsize Mazda 6’s turn to try ditching gasoline. Will anyone be in line to greet it? (Read More…)

2019 Ford F150 Lariat FX4 front quarter

I’ve never owned a truck. Over my two-plus decades of driving, I’ve shopped for trucks new and used, but have always stopped short of stroking a check for something with a bed for various reasons big and little. Typically I needed something with more interior space, more lockable cargo space, or more comfort — but one thing always holding me back was fuel economy. Traditionally, trucks aren’t particularly efficient.

However, modern diesel engines can yield impressive economy, which is why we’re beginning to see them trickle into the half-ton range of pickups from each of the Detroit Three. Ford, long the sales leader in the segment, has given the Power Stroke treatment to this F-150, and we were curious if it improves an already impressive truck.

2015 Volkswagen Jetta TDI brown

While it absolutely pales in comparison to the fines levied in the United States, Volkswagen will still have to fork over a pile to appease the Canadians.

This week, the automaker pleaded guilty to 60 charges relating to its deception of regulators and consumers with emissions-rigged diesel vehicles. While $196.5 million sounds like small potatoes in this day and age, it happens to be the largest monetary fine for an environmental crime in the country’s history. (Read More…)

Mitsubishi is under investigation by German prosecutors for the suspected use of illegal defeat devices on diesel engines. As usual, the probe was kicked off by a series of raids — practically a cliche at this point.

Germany has certainly ran with the concept after U.S. regulators faulted Volkswagen for using illegal defeat devices to cheat diesel emission testing procedures in 2015. The reality is that regulators are cracking down the world over since the scandal, with Deutschland taking extra precautions to ensure other domestic brands don’t shame themselves like VW did.

Investigators are looking at 1.6-liter and 2.2-liter 4-cylinder Euro 5 and Euro 6 diesel engines and asking individuals who own Mitsubishi models (built after 2014) with those units to contact the police.  (Read More…)

Over 200 investors are seeking 900 million euros in damages over claims that Mercedes-Benz parent Daimler failed to disclose the use of emissions cheating devices similar to those that got Volkswagen into trouble back in 2015. This isn’t the first time the issue has come up. German prosecutors claimed nearly 690,000 Mercedes-Benz vehicles came equipped with rigged exhaust gas after-treatment systems and Daimler was slammed with a €870 million ($960 million) fine over the negligent violation of European clean air standards in the fall.

Those who invested into the firm are hoping to recoup losses from the scandal after the automaker’s share price shat the bed. Lawyers repressing the investors are seeking compensation after Daimler’s stock fell from €90 a share fall to approximately €60 in 2018, once German regulators began formally accusing the automaker of trying to circumvent emission rules.  (Read More…)
