IMO these were the most telling comments on the trial:

The earlier comment on differences between diesel fuel and gasoline are worth repeating. A gallon of diesel fuel typical releases about 15% more thermal energy than a gallon of gasoline when burned. So comparing gallons of diesel to gallons of gasoline when measuring efficiency really is comparing apples to oranges, in spite of the authors' claims otherwise. On a 'mile per unit of thermal energy' basis, the Prius won. On a 'miles per dollar of fuel' basis, the Prius won, although the E250 would have won that category in Europe due to tax differences between US and EU. That said, I've owned 6 vehicles with VW diesel engines, and liked them a lot. Prius not in my top 10 desirable vehicles.

I've put over 200,000 miles on my two VW diesels over the past few years. My Passat get close to 50 MPG on the highway and Sportwagen, with its roof rack, around 45. And they are fun to drive. I did test drive a Prius and to be honest, would rather ride a bus than drive that thing.
