That fast back crap won't help a bit, it will only add weight. A pickup truck already gets that effect by the turbulant air behind the cab with no extra weight.
Sorry, I have to correct that one, it doesn't completely create that effect, it causes air to go over the turbulent air, or "air bubble" but doesn't lessen the air wall that is behind the truck. the point is to cause the air to flow down the said "fastback" and create the smallest air trail behind you as possible. if it's traveling over the "air bubble" it's working more like those covers that make the truck look more like an SUV than a truck. Therefore you have a large trail of air behind you like my suv would make, but this would create a sedan effect, making only a small trail of swirling air behind you as tall as the tailgate is, instead of as tall as the roof line.

If you made that Boat tail, what would you make it out of? would be the question. Some would choose Coroplast, some would go with fiber glass. In any event, I think that it being a truck, with basically a wall for a window that even though you add 50kg's, you'll save about 80+ if your like me and drive about 85% Highway, 15% city. That's a lot. Look up Basjoos's aerocivic.

I know your just trying to say that, for most people who drive more in the city, it will actually hurt them more than help, but the ecomodders who will craft one themselves drive more on the highway, which is why they are doing this. The ecomodders who drive in the city will slim and trim down their vehicles.




Not trying to bag on ya or anything, but if you look at the cover, it's definitely not made from a metal, but more of a plastic or fiberglass application. For this guy, it saved him money, for the guy who lived deep in the city, will cost him money. That's why they're either DIY or Aftermarket covers (the non fastback ones that are square and turn a regular truck into an SUV) because if they were standard, it wouldn't help everyone. the ones that it WOULD help, buy them to do so.

I get what your saying. And it's a good point.
