Handy if you happen to drive into the back
of one, also. |

And a Merry Christmas to half and all. |

Would also be handy for the modified-with-skirts and spoilers crowd. Instead of fiberglass repair, you just detach the mounting points and install a new car-loon. |

Saw this idea in PopSci long time ago, no one ever went anywhere with it. I don't know why not, but whatever the reasons are I'm applying all of them to your idea. |

And bunning it anyway. Anything that raises fuel mileage in the fuel-thirstiest vehicles on the road can't be all bad. |

BMW car carriers have a sort of curvy arse, why is that? Does anyone know what's going on inside that big rounded bustle on BMW's enclosed transporters? |
|
| |
The best shape seems to be a blunt, rounded dome. There are already regulations in some countries to limit the protrusion of following aerodynamic aids to 5 feet. |
|
| |
The other big savings are to be had in fairing the underbody and sides of trailers, especially the wheels. That would also prevent a lot of accidents involving run-over by the rear axles. |
|

[UB], I agree, I think you could add a couple of aero add-ons reasonably easily to cover the gap between the trailer and the cab, the trailer and the ground and maybe even a hollow nose cone(for cooling), especially for cab-overs with flat fronts. |

The idea being to design them to be inflatable on the highway and then vacuum deflated and auto-stored away for city trafic. |

I worked in transport for a while. We could never understand why trucks weren't designed with a central driving position, to allow cabins to be made more aerodynamic. |
|
| |
[UB], some designer cranked out a stack of aerodynamic concepts, and named them all Utah x (x = positive integer). A couple of them were trucks, one had a central driving position and, strangest of all, a gigantic hole in the center the directed airflow at the front of the trailer. With a rounded front on the trailer, that plus the airflow coming around the side of the cab made for a nearly-laminar flow around the trailer. Neat, but weird. |
