In the wake of the diesel tide that was the Detroit Auto Show, we decided to hoodwink talk our friends at Honeywell into providing us with some of the most forbidden fruits of the Euro-spec diesel world. As a result we've been living and commuting with the not-for-the-USA 2007 Honda Civic i-CTDi and the 2007 Audi Q7 4.2 TDI for the last week. Over the next three days we'll be laying out our reviews of these cars and of how they fit the driving habits of the average American consumer. We'll be reviewing them separately today and tomorrow, with something special planned for Friday so sit back and enjoy the oil burning ride.
