In the past, the Environmental Protection Agency (EPA) typically issued grants for the advancement of proven technologies and rarely offered up government money on projects that some would consider experimental. As environmental concerns rose in recent years, the EPA created its emerging technologies program to fund unproven, cutting-edge advancements that offer the promise of reduced emissions and improved air quality. The program kicked off in 2008 with an aim to offer assistance to companies

Regular readers know we tend to be big fans of modern diesel engines. All the past demons that had plagued oil-burners over the years have been exorcised, including rough running, nasty smells, loud operation and narrow power bands.

This 163 hp unit replaces the 2-liter 143 hp unit and burns 7.1 l/100 km (33 mpg U.S.). The new diesel featu

In a rare move that probably won't attract the level of controversy or public comments that seem to be standard for EPA announcements these days (e.g.: California waiver), administrator Lisa Jackson will be in Ohio on Wednesday to talk about American Recovery and Reinvestment Act of 2009 grants for auto manufacturing communities, specifically clean diesel grants.

We recently received a note from an anonymous source indicating that there's a mildly strained relationship between VW and some of its dealers. The source of the consternation seems to be the highly anticipated Jetta TDI, which was just recently released in the U.S. market.
