Yup, you read that right. A VW Passat Bluemotion has was followed around by a Guinness crew, who witnessed a 20.4 gallon tank be completely filled up with diesel and emptied 1,527 miles later. Average speed for the trip was 45 MPH.

That’s some pretty good mpg, Hans. Of course, domestic automakers continue to build giant SUVs and hope their lobbying efforts pay off instead of building a car Americans would be proud to buy. Sheesh.
