Saw a tractor and trailor pass through Lowville this morning with wings on the back of the trailor. First time I've ever seen that. They were aimed in at about a 20-30 degree angle.

Would this be for better fuel milage -- to keep the road slop off the back, or both?
 
It wasn't a Red Bull truck was it? Cause Red Bull gives you wings... (sorry it is Monday morning lol)
 
LOl!!!!

Used to work on a production line. Guy side of me would down two Red Bulls before production started and another before 10:30 break. The guy almost literally did have wings!
 
Those are aerodynamics as said, ssupposed to break the suction behind the trailer and improve milage. California is trying to outlaw them for making the teailers over length.
 
THE SAD PART IS CALIFORNIA IS THE STATE BEHIND ALL OF THE SKIRTS AND WINGS ON TRAILER TRYING TO MAKE THE TRUCKS GET BETTER MILAGE. WITH ALL THE RESTRICTIONS THEY PUT ON BIG TRUCKS YOU CAN HARDLY GET A TRUCK TO GO TO CALIFORNIA ANYMORE. NO WANDER THEY ARE BROKE.
 
I was going to ask John F if he had heard anyone quote the savings. To me it would take a long time to recover the cost of the device, instillation and the aggravation of messing with the things. Just wondered what the real results were.
 
if you have an older truck that gets 7 miles per gallon you are not aloud to go into cal. -- you need one of those newer ones that cant get past 5 mpg-- well guess who wants to go there? no one !DAA!
 
Dart doesn't have any trailers with the rear wings, but the bottom wings get me .25-.5 mpg extra. The propaganda on the tails claims .25 mpg.
 
The newer trucks are back up to over 7 mpg again. Mine is at 7.78 mpg since new at 260,813 miles.
 
The wings on the back of a trailer are claimed to improve mpg 1%.
Not a big deal. That's why you do not see many of them.
The newer version opens and closes automatically with road speed so not much aggravation.

The low rider wings that go under the trailer from the landing gear to front of the trailer tire are a different story. They are claiming 5 to almost 6% better mpg. That's $2500 for every 100,000 miles based on 6 mpg and $3 fuel.
That's why you are starting to see a lot of these flaring's.
