Mercedes Benz 2012 Aerodynamic Truck and Trailer
 

It has been listed here before, but I stumbled on this video which gives one a better look at some of the detail:

I need to look at it again, but the main thing I noticed, that I didn't see in other images was the side ducts at the rear bringing in air from behind the wheels and into the base drag zone.

It has the air turning deflecters on the front corners and a duct built in at edge of headlight housing to do the same, so giving the effect of a more rounded face I imagine.

The boat tail is short, but under european regulations it is not allowed at all, but they are hoping to get approval in the near future from changed legislation.

Can't see it unless I launch a browser that supports Flash™.

Is it the Actros? Here's a video about it (there seem to be many)

that shows a secret feature at 4:45. I think the best feature is the cab you can stand up in with a murphy bed.

Yeah, I think the other Vid is a Flash player,

It has all the comforts, but my main goal was trying to identify what aero improvements have been done and how they may be adapted to the small truck/pickup/van/RV types of situations found here.
