The EB downhill mileage makes ZERO sense. The fuel cuts off when coasting, and the mileage should have been well into the 30's. Something doesn't add up there. I'm not suggesting it will match the mileage of any truck with 240hp,& a superior transmission; I'm merely pointing out that the numbers make no sense. (over 100 000miles of experience with all manner of late model F150's speaking here).
Not much of a comparison, as the was NO control at all of the many variables.
I don't know about you, but there is no coasting downhill when I tow. If I let off the throttle, I am slowing down.
If that is the case, why are exhaust brakes on diesels so popular? And why is the Ecoboost faulted for not having enough engine braking when coming down from altitude?
I would assume the big diesels with some type of retarding feature, are towing bigger trailers. These weight of these bigger trailers probably overcome the wind resistance a lot easier as gravity is acting on more mass. There are hills that I tow on that have truck runaway ramps and I have to keep pulling all the way down those hills. The VM A630 (Ecodiesel) is not made to pull these heavy loads, so no exhaust brake is needed, IMHO.
