Fans of small victories will appreciate the "progress" that Americans made with their purchases of green-car vehicles last month. Automakers and everyone else, though, will scratch their heads. That's because green-car sales had their fourth straight down month in September, as Americans purchased about 42,000 hybrids, plug-ins and diesels last month. And while the deficit compared to last year wasn't as steep as August's 11 percent year-over-year decline, sales were still down 9.6 percent and c

Will BMW's Gas-Electric Tech Finally Do The Trick?

Rolls-Royce is not what you might characterize as one of the greenest automakers on the market. Its vehicles tend to be rather large, saddled with lots of plush leather, thick carpets and wood trim, and powered by twelve-cylinder engines in excess of six and a half liters. But that doesn't mean that the stoic British automaker isn't trying to clean up its act, even if its customers haven't responded in kind.

Burning Extra-Virgin Olive Oil Is Cheaper But Less Exciting Than You'd Think

It used to be easier to make sense of the auto industry. There were mainstream manufacturers, and there were niche sports car manufacturers. That was before Porsche starting selling more crossovers than it does sports cars, Lamborghini began preparing to go down the same road, and Ferrari introduced an all-wheel-drive hatchback. But long before the arrival of the Cayenne, the unveiling of the Urus and the advent of the FF, the storied marque that is Maserati was already bolstering its sports car

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.

Is this water electrolysis hydrogen scheme for real?

Recently, we ran an article: LeefH2 wants to clean up pretty much every diesel engine and it mentioned the way HNO Green Fuels, the maker of the LeefH2, wants to create oxygen from a diesel engine while also reducing particulate matter. I had some concerns with that.

Could the "Zoom Zoom" automaker start making hybrids that go "glug glug glug"? Mazda, known for its fuel-efficient Skyactiv engine line, will be the first Japanese automaker to make a diesel-hybrid vehicle for Japan and Europe.

This Is What Happens When You Smoke Out A State Rep

It's always a few bad apples who ruin polluting just for fun for the rest of us. That time-honored American tradition of being rude for laughs, otherwise known as 'rolling coal,' might become illegal in New Jersey, if a Nissan Leaf-driving politician gets his way.

The desire for more diesel vehicles on American roads has become a popular talking point among automotive enthusiasts. We hear about the super-efficient, high performance oil burners cruising all over Europe and don't see any reason that they couldn't work here. After all, their high torque figures and great range would seem like a perfect match for US roads, even if their fuel is generally more expensive than gasoline. It looks like General Motors might be listening, though. Steve Kiefer, the a

Our Staff Voices Their Unpopular Opinions... How About You?

We all have controversial opinions. Be it whether you think the Nissan Juke is actually pretty attractive, manual transmissions aren't always better, or you honestly didn't hate the Pontiac Aztek, we all harbor some persuasion, be it big or small, for which we catch copious flak upon expression.

Going against popular perception, diesel vehicles are showing some pretty good pickup. The context, of course, is US sales of oil-burners. And those sales are on the rise as more Americans look to cut refueling costs via more fuel-efficient vehicles.

Is Kia making diesel rumors a biennial thing? The South Korean automaker once again may take a closer look at making an oil-burner available for US consumption, JustAuto says. All in the name of fuel economy, of course.

Nope, the diesel engine never really did go out of style for Audi. Now, the German automaker has released a video reminding the world of its persistence with the oil-burners and is commemorating the Silver Anniversary of Audi's first commitment to turbodiesels in 1989. And, yes, there are some road racers shown in the clip, so some of those bad boys actually move pretty well.

Dirty engines used to harass pedestrians, other drivers

The owners of these trucks already love their diesel engines, but for their bad boy reputation.

Australian consumers appear poised to get another diesel-burning luxury SUV in the near future, and word is it's coming from Lexus, of all automakers. Sean Hanley, chief executive of the company's branch in Oz, recently told Aussie website Drive that he's "pretty confident" that the new engine for the LX is getting the green light.

When it comes to diesel trucks, the good old days weren't so good. Go back a quarter-century, for instance. Back then, a single diesel-powered truck was throwing off about 60 times the emissions a typical "clean diesel" truck does today. Cough.

For The First Time, Fusion Energy Beats Chevy Volt

We have to blame the VW oil burners and Malibu mild-hybrids.

If you're in the market for a hot hatch, there are some excellent choices at your disposal – especially if you live in Europe. But if you want a diesel, well, your choices become rather more limited. Volkswagen tends to that niche market with the Golf GTD (essentially an oil-burning version of the GTI available Stateside), but that's about the extent of it. The pleas of those looking for more diesel-burning hot hatch choices haven't fallen on deaf ears at Ford, with the Blue Oval not only

US government handing out $1 million to improve air quality

Everyone deserves clean air, but the Environmental Protection Agency (EPA) has never directly offered diesel emission reduction program assistance to tribal (aka Native American) entities before. This is what makes a new announcement from the EPA about a million dollars targeted at reducing emissions from older diesel engines a bit more interesting than usual.

Diesel and hybrids both selling well in Texas, California

As we've already learned, 2013 was a pretty big year for diesel and hybrid sales. According to registration data, there are now 7 million diesel passenger vehicles and 2.8 million hybrids on the roads in the US. Diesel registrations grew by 410,040 last year, and hybrids increased by 531,385. From 2010 to 2013, diesel registrations increased by 30 percent, and hybrid sales grew by 64.5 percent. When compared to an overall market growth of just 3.7 percent, those numbers are remarkable. Diesel Te

You can reap big long-term ownership savings by getting one of these efficient vehicles

Diesel vehicles typically save $2,000 to $6,000 in total ownership costs over three to five years when compared to similar gasoline models.

People rightfully dislike wireless signals being transmitted from the person behind the wheel when they text while drive, but there are times when a car's wireless signals can be good news. Researchers at the Massachusetts Institute of Technology (MIT) have found a way to use wireless signals under the hood to help cut pollution from heavy-duty vehicles such as diesel-powered trucks. That's something we can get behind.
