CNET:

When I first began talking with Audi about road-testing the company’s new Q7 TDI clean diesel SUV on Road Trip 2009, I have to admit that I was more than a little bit suspicious of that term.

“Clean diesel.” It sounded a lot like another new term of art, “clean coal,” and I think we know pretty well that there really isn’t much that’s clean about coal. Plus, I think many of us have negative associations with diesel, a technology long known for sooty fumes, loud engines, and a whole lot of pollution.
Still, Audi was talking about high fuel efficiency, low emissions, and an engine that rivaled–or even surpassed–the power of its traditional gasoline counterparts. Indeed, there was even the discussion about outdoing hybrids for overall performance in certain driving conditions.
