Clean Diesel

This isn't over yet, but it's one step closer now.

The FTC has announced a lawsuit against VW over its 'deceptive and unfair practices' as it advertised its 'clean diesel' vehicles.

After diesel models from Toyota, Nissan, and Mitsubishi failed real-world emissions tests, Japanese regulators plan to begin doing as part of its evaluations.

German automaker has already launched $1,000 'Goodwill' plan for car owners.

Someone is shaming Volkswagen TDI owners by posting flyers full of bad information on the cars in Portland, OR.

Many VW diesel owners, and potential owners, are mad at the automaker for its deceptive emission practices.

Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the federal government charged Friday.

Imagine if a little bit of water could make your internal combustion engine run cleaner and more efficiently, and help it produce more oxygen than a tree. That's what the LeefH2 device is designed to help your motor do. HNO Green Fuels, the maker of the LeefH2, wants to turn your engine – and every other combustion engine – into an oxygen farm while reducing particulate matter and getting more power out of your fuel.

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.

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, John Beltz Snyder

Airborne particulate matter can really do a number on us humans, particularly with regard to our cardiovascular systems. It seems reasonable for air pollution, then, to be a major concern when calculating the environmental and health costs of the way we do business. Diesel-powered transport has come under particularly

Diesel fumes are bad for people. But diesel power is good for a lot of heavy-duty work. So, for now, one answer to threading the needle of that little conundrum is to

Today, if you're a car company and you offer a diesel engine in this market, you have to go to great lengths to show consumers that it's less harmful to the environment than a gas-powered engine. That's why marketing types have come up with TDI Clean Diesel and EcoDiesel and Brandon Turkus

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here – perhaps not surprising when the two brands offer a total of 12 diesel models.

Luxury SUV and non-luxury car shoppers are the most inclined to consider alternative fuel vehicles. Not surprisingly, consumers looking for trucks are the least likely, according to a 2013 study from Phoenix Marketing International (PMI). Fuel-efficient "clean diesel" luxury SUVs from German automakers are warming up luxury SUV shoppers to alt-fuel powertrains like electric, hybrid, hydrogen or natural gas – but those options haven't been enough yet for truck shoppers.

Audi, in case you haven't noticed, is quite committed to diesel technology. It champions oil burners in both the racing world and to consumers, offering American customers a total of five diesel-powered models, which is more than any brand in the US market save for its parent company, Brandon Turkus

Volkswagen claims its newly launched Golf TDI BlueMotion is about as good as it gets with that old standby, the internal combustion engine. The new Golf consumes 3.2 liters of diesel per 100 kilometers, the equivalent of getting 73.5 US miles per gallon (on the European cycle), a 15-percent improvement in fuel economy over the previou

Here's the thing: it takes a lot of practice to drive like a true hypermiler. The 2013 VW Passat TDI Clean Diesel with a manual transmission, for example, has an EPA estimated 31 city/43 highway mile per gallon rating. Hypermiler Wayne Gerdes thinks the car is good for at least 68 mpg.

The fight to be the most popular fuel for commercial trucks wages on between the natural gas and clean diesel factions, with alt-player biodiesel joining forces with the Diesel Technology Forum team. The National Biodiesel Board joined up with the forum to improve diesel's reputation in Washington, and beyond, at a time when natural gas is gaining support.

Germany's largest automakers are renewing their pitch for their clean-diesel vehicles in the US as a way for consumers to combat high gas prices without having to resort to the (often) even pricier hybrid and plug-in hybrid options.
