VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx. VW’s ultra-low emission Jetta BlueTDI will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.This newer version of the Jetta will meet the strictest emissions standards in the world.

Scania (part of Volkswagen) builds modified, heavy-duty diesel engines designed to run on almost pure ethanol (E95, or 95% ethanol, with a 5% ignition improver).If that sounds weird, that’s because it is. US auto manufacturers make a big deal out of converting cars and trucks to run on ethanol/gasoline blends of up to 85% ethanol.

Everything you ever wanted to know about biodiesel. While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.

Mercedes plans to release a diesel-hybrid SUV capable of 40 miles per gallon, with cleaner emissions than your standard car. Demo’d at the 2008 Geneva Auto show, the SUV is built on Mercedes’ relatively new BlueTec emissions control technology—a combination of catalytic converters and advanced chemical processing that scrubs out the worst pollutants produced by the diesel engine.

Farmers in Northern Queensland, Australia, are investigating another approach to producing renewable fuel: growing diesel trees. As weird as that sounds, it’s real, and it isn’t a scientific breakthrough. We’ve actually known about the trees for over 300 years.

Wind turbines have replaced 50 diesel generators on the Galapagos - a step towards sustainability.

Allen Schaefer, Executive Director, Diesel Technology Forum, is interviewed on advancements in clean diesel transportation, advantages of clean diesel as a fuel source and the differences between clean diesel and biodiesel.

As if it wasn’t bad enough that particulate matter from diesel exhaust causes a range of respiratory problems including 15,000 premature deaths each year, new research shows that even short-term exposure to nanoparticles found in diesel fumes can affect brain

While virtually everyone is familiar with the use of biodiesel as a substitute for diesel fuel, there are a few novel uses that may not have crossed your radar. Biodiesel can produce hydrogen, clean up oil spills, degrease your tools, heat your home, and more.

A few years ago, VW created a secret car that uses only 1 liter of fuel for every 100 km. That’s 285 MPG, and it's not a hybrid. It's a super-efficient lightweight diesel. Take a look at what they did...

Trying to learn how to make biodiesel, or interested in seeing how it’s done? It always helps to get a visual, and you may not be aware that there are currently enough biodiesel videos on YouTube to develop an entire college course on the subject. I’ve thrown out a representative sample, just to give you an idea of what’s available.

Toyota may lose its high-mileage stranglehold on the U.S. auto industry, thanks to Volkswagon’s new Golf hybrid-electric diesel.

Looking to find a source of biodiesel? This guide will help you figure out how to get from A to B exclusively on biodiesel.

The German company Loremo (short for low-resistance mobile) released a turbodiesel sportscar at last September´s Frankfurt International Auto Show capable of a whopping 117 mpg and range of no less than 621 miles. They also plan on hybrid and electric models, and even one that runs on vegetable oil.

Don't try this at home, but Transonic Combustion, has created a fuel injection system that will let diesel engines run on regular gasoline. The company's fuel injection system dramatically increases the internal compression in an engine, a standard 2.3-liter diesel engine that gets 50 miles per gallon can get 100 miles per gallon when retrofitted.
