Well credit where it's due, this did actually happen, and happens often during MPG Marathons and the like. I just want to know how they keep it up over long distances. Must have been a very well panned routed avoiding all urban areas etc.
For anyone sceptical about the official MPG figures of diesels, apparently someone managed an amazing 97 MPG in a Gold TDI recently. And it wasn't a short trip either, a cross continent road trip of 995 miles. Good going!
