69Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

From drag races to roominess comparison, the Mazda3 came out ahead of the Audi A3 and BMW 1-Series in a diesel-hatchback comparison.

41Renault reveals tiny two-stroke twincharged diesel

The Renault-Nissan Alliance bills itself as the worldwide leader in electric vehicles with a claimed 58 percent of the global market share. In the highly competitive world of increasingly efficient powertrains, development can never stand still if the company wants to maintain that dominance. Renault just held a show of its latest drivetrain prototypes. The most bizarre of them wasn't electrified, but it was so weird that it needed to be shared.

4November 2014: The not-so-down-is-the-new-up edition

Last month, Nissan and BMW helped stem a disconcerting (for green-car watchers, at least) trend of declining year-over-year sales, as increased demand for the Japanese and German automakers' plug-in models made November slightly less painful than October. The year-over year decline of hybrid, plug-in and diesel sales narrowed to 10 percent in November from 13 percent in October, as Americans bought more than 43,000 new green cars. Last month's plug-in sales reversed their temporary decline, incr

74France says diesel cars a 'mistake,' announces phase-out plans

Anyone even vaguely familiar with the European auto market knows that diesel-fueled vehicles take up a huge portion of the roads there. A combination of high fuel efficiency, useful torque in tightly packed cities, low CO2 emissions and tax incentives all contribute to the popularity. However, ever the iconoclasts, the French government wants the oil burners off its roads in the coming years.

65Volkswagen announces new 268-hp TDI diesel, 10-speed DSG

We won't even ask how much torque it'll produce, but we could easily see the number cresting 450 lb-ft.

5Chrysler recalling 382k Ram HD diesel pickups, 184k SUVs

Between GM's ignition switches and Takata's airbags, it's been a big year for recalls, but they keep rolling in. The latest comes from Chrysler, which has announced a pair of recalls for certain heavy-duty pickups and SUVs.

18Land Rover mulling Evoque diesel for US

Jaguar Land Rover offers nearly all its models (save for the F-Type and outgoing XK) with diesel engines... it just doesn't offer any of them in the United States. But that's about to change, and that change is tipped to start with the Range Rover Evoque.

26September 2014: A tiny-step-in-the-right-direction edition

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

6Rolls-Royce gives up on electric, diesel models in favor of hybrid

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.

422014 Maserati Ghibli Diesel

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

10Audi recalling 70k TDI models worldwide over braking problem [UPDATE]

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.

29Q&A with HNO Green Fuels on their oxygen-creating LeefH2 device

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.

2Will Mazda sell diesel hybrids in Japan in 2016?

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.

280Angry Nissan Leaf Driver may make 'Rolling Coal' illegal in New Jersey

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.

62GM says it will offer more diesels in US, but on which vehicles?

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

306Autoblog editors come clean about their controversial automotive beliefs

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.

AddUS diesel vehicle sales are up 25% this year

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.

35Kia still said to be considering diesels in US

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.

3Audi celebrates 25 years of TDI

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.

471Rollin' Coal: A Dirty Subculture Among Diesel Truck Owners

Dirty engines used to harass pedestrians, other drivers

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

18Lexus LX to get diesel engine?

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.
