5Alpina B5 Biturbo sedan looks the M5 square in the eyes

Do you love the notion of the 507-horsepower, twin-tubocharged Alpina B5 Touring, but just can't get behind a high-performance family wagon? Alpina has good news for you. The company has officially pulled back the curtain on the new B5 Sedan, and the vehicle boasts the same wicked driveline as its long-roof twin. That means there's a dizzying 516 pound-feet of torque pouring out of the same forced-induction 4.4-liter V8. A ZF eight-speed automatic transmission takes care of gear-swapping duties

AddPreem to offer B15 biodiesel across Sweden beginning in April

Beginning in April, Swedish oil giant Preem will offer diesel blends containing 15 percent renewable diesel (B15) and 5 percent biodiesel (B5) at 366 fueling stations throughout Sweden. The B15 blend, which Preem fittingly calls Evolution Diesel, is claimed to cut carbon dioxide emissions by 16 percent compared to conventional ultra-low-sulfur diesel.

4Alpina teases BMW B5 Bi-Turbo ahead of Goodwood debut

The Alpina B5 has been spotted a couple of times and seen front and back, so it's pretty clear what we'll be in for. However, before the car's official unveiling at the Goodwood Festival of Speed in July, Alpina has released a sketch of what will be one of the hottest 5ers that doesn't begin with an "M." There will be two turbos stuck to the engine lurking behind that highly slatted front end, and we're told that "there will be an eye towards fuel economy with this car." But presumably, just one

AddGreenlings: PHEV? DSG? VMT? A guide to common green vehicle acronyms

Guide to Common Green Acronymns

Deciphering the new vocabulary of the green car movement can sometimes be a real head scratcher. To alleviate as much confusion as possible, we would like to present our readers with a list of common acronyms and what they mean, with plenty of links for more information. If you have some TLAs (that's three-letter acronyms) that you'd like us to add to our glossary, just let us know in the comments.

AddTry B100? Not in your new diesel engine

Manufacturers of diesel engines make it clear that small amounts of biodiesel are usually fine (most say B5, or diesel with five percent biodiesel mixed in, is OK), but they won't make any promises about higher concentrations. Popular Mechanics has a good article that explains that these companies aren't just trying to make life difficult for plant-fuel lovers: there's technology in new diesel cars that doesn't play nice with biodiesel. The Environment Protection Agency and the California Air Re

AddBiodiesel can't void your warranty?

Most manufacturers, including heavy-hitters like Volkswagen and Mercedes-Benz, allow the use of a 5 percent biodiesel blend (aka B5) without violating the terms of the car's original factory warranty. What happens if you use a higher biodiesel concentration? That's a good question, and the answer isn't particularly clear at the moment. According to Steve Keyes, Volkswagen's director of public relations, "All Volkswagen TDI models are warranted for the use of up to a B5 blend. Blends of biodiesel

AddEPA ups America's Renewable Fuel Standard to 10.21 percent for 2009

In 2009, the U.S. will use at least 11.1 billion gallons of renewable fuel. This was the pronouncement of the EPA today regarding an increase in the Renewable Fuel Standard Increased from 7.76 percent (the 2008 number) to 10.21 percent, an increase of 2.45 percentage points or about 2 billion gallons. The 11-plus billion gallons will be blended into transportation gasoline as E10, E85 and different types of biodiesel blends. The raise continues the EPA's policy of gradual increases in the annual

AddComprehensive list of biodiesel myths dispelled

Gas2.0, a website focused on biofuels, has published a very interesting set of 22 dispelled biodiesel myths. Some of them are dispensed with very straightforwardly and all are in favor of using biodiesel.

AddWashington State farmers experiment with canola as biodiesel cash crop

Farmers in Washington State are experimenting with canola for biodiesel production as a new cash crop to supplement existing diary or vegetable crop income. Conditions in Snohomish County, which boasts cool temperatures, moist sea air and good soils, are proving to be so ideal for canola growing that yields are vastly outpacing European norms. Last year Snohomish County farmers averaged 158 gallons / 598 L of biodiesel per acre of planted canola compared to just 84 gallons / 318 L of biodiesel p

AddCummins approves the use of B20 in some engine ranges

With the growing acceptance of biodiesel, the fuel has become more available and standards are being created to make sure that all biodiesels are created equal. With some of those hurdles being overcome, manufactures are able to do a better job of testing and ensuring that their engines will operate on biodiesel blends with a higher concentration of renewable fuels. Cummins has done exactly that, and has announced that their 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines a

AddNew Mexico House passes B5 by 2012 bill with 47-8 vote

New Mexico has voted a through a House Bill that would require all diesel fuel sold in the state to be B5 by 2012. The bill, which passed the House in a 47-8 vote, moves to make diesel fuel containing five percent biodiesel compulsory for all state agencies and public schools from July 2010 onwards. All diesel fuel would move to a B5 blend by July 2012. In case of poor product availability or excessive price however, the measure could be suspended by officials.

99In the Autoblog Driveway: 2003 VW Jetta SVO (Straight Vegetable Oil)

One lesser-known movement in green car technology is converting diesels to run on SVO, or Straight Vegetable Oil. Unlike biodiesel, which is produced by chemically modifying vegetable oil so that it can be used in a diesel vehicle with no modifications, SVO requires a second fuel system for the vegetable oil in addition to the standard diesel fuel system. Also, one doesn’t operate and fill up an SVO vehicle like a normal petrol or diesel car. It sounds like a lot of work, so why are more a
