Here's a link I just found for the new Audi A3 TDI. I'm a huge fan of all things Toyota, but feel that more manufactures should get onboard w/ the diesels. I feel that they're almost missing the mark w/ hybrid vs. diesel technology.
I don't know the stats, but I think a large majority of European vehicles are diesels. I drove a 2005 Jetta TDI about a month ago, and got around 50mpg!
Wouldn't it be great to have a Tacoma getting 30+ mpg, and all the torque that you could handle that a diesels typically put out.
