It looks like VW won’t be sending a diesel hybrid to the US after all. VW announced the 70 MPG diesel-hybrid electric Golf at the Geneva Motor Show, but turned around in the March 27 edition of Auto, Motor und Sport to say they wouldn’t be building the car because it would be “too expensive.” Read the rest of this entry »
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—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).

It looks like Solazyme will be making algal biodiesel for the US military, after a test-drive demonstrated the fuel’s superior cold-weather properties when compared to commercially-available biodiesel.Former Director of Central Intelligence and Under-Secretary of the Navy R. James Woolsey tested the fuel himself by driving to the Worldwide Energy Conference & Trade Show in an unmodified 2008 Ford F450 fueled by 100% algal biodiesel. Read the rest of this entry »
I’ve posted in the past about a possible hybrid LeMans car and performance diesels, but today there is some actual news on some non-gasoline race cars from Audi. As reported by AutoBlogGreen, Audi recently took second place in their first showing with the diesel-powered cars in the European LeMans (this is after having raced these cars since 2006 outside of Europe).
The new Vision GLK BlueTec hybrid sports a standard hybrid-electric system: An electric motor seamlessly supplements the 2.2 liter diesel engine during fuel-intensive acceleration. Regenerative braking repowers the lithium-ion batteries, and start-stop technology shuts the motor off when the car is at a dead stop.
This is what a team of engineers can do when challenged to push the limits of fuel efficiency and technology. You may have already heard of VW’s 1-liter car, but take a closer look. It’s a sports-economy concept car produced a few years ago by VW engineers, to answer one big question: could they build a car that consumes less than 3 liters of fuel for every 100 km traveled?
We all know that fast cars are fun and fuel-sipping cars are environmentally responsible, but is there a middle ground?
Short of expensive electric sports cars like the Tesla Roadster, there may be a solution to be found in diesel. Not only can diesel cars be fueled with waste vegetable oil, biodiesel, or some mixture of these fuels, but diesel engines produce a lot of torque and get better fuel economy than their gasoline-powered brethren.
Update: VW announced this car will not be built because it was deemed “too expensive.” Sorry Folks, VW Diesel Electric Hybrid Not Coming to US.
Toyota may lose its high-mileage stranglehold on the U.S. auto industry, thanks to Volkswagen’s new Golf hybrid-electric diesel. At 69.9 MPG, the new model is a serious contender for high-mileage biodiesel usage with a ridiculously low-emissions profile, especially since it will meet the strictest emissions standards in the world: Europe’s Euro V and America’s Tier II Bin 5.
This makes it likely to be released in California, since the major impediment to U.S. diesel vehicle sales has been emissions technology. But VW doesn’t plan on releasing the vehicle in until Europe late next year, which means we’d optimistically see a U.S. version sometime in 2010.
High-mileage-sportscar may sound like an oxymoron, and it’s a fair question to ask what was sacrificed to get 117 MPG out of this sleek, sporty-looking turbo-diesel, which is available in two models: a 2-cylinder LS and a 3-cylinder GT.
Besides the cool-looking flip-up lid and snazzy interior, Loremo’s real innovation (if the name was any hint) is based on two fuel economy fundamentals: substantially reducing weight and drag.
Thinking about ‘converting’ to biodiesel?
It’s not as hard as you think.
This series of posts is intended for readers looking to start using biodiesel by finding an older diesel vehicle, ‘converting it’, and then finding a local fuel source.
Before embarking on a biodiesel adventure, it may be a good idea to determine whether biodiesel is available in your area (it probably is), and most importantly, whether or not it’s conveniently located. While some of us are willing to go to great lengths to find and use alternatives to petroleum-based fuels, this isn’t practical for everyone.
For information on how to find biodiesel, see 6 Ways To Find And Use Biodiesel Anywhere, and for more background you may want to get started with the Biodiesel Mythbuster. This post is primarily focused on buying a used diesel, but it should be helpful to anyone interested in using biodiesel.
It’s important to understand that any diesel engine can run on any blend of biodiesel with no major conversion. In older vehicles, it’s not a bad idea to change out fuel lines (biodiesel eats rubber over time), but don’t let anyone convince you that this is difficult or expensive (more on this later). First, let’s find your first biodiesel vehicle:
