Since joining this site, I have really noticed a lot of semi trucks with side skirts on the trailers.
Example site is at
Proven 7% Savings in Tractor Trailer Fuel Costs | Frieght Wing.
Are semi truck drivers going to lead the aero change over since they are ran less by looks over function? A 7% gain for a semi is quite a lot since they drive so far O.o. I know they have had the top caps for a while for the cab to trailer line to be more aero, but the side skirts is something new for me.
Also has anyone else noticed these? I live in michigan, and economy is complete crap where I live.
Discuss....
