Transport truck "Trailer Tail" - aftermarket aero kit ~5% MPG improvement (video)

Saw this today:

Quote:
ATDynamics TrailerTail ® – increases fuel efficiency of tractor trailers by over 5%

In 2008 it became the first and still the only rear fairing to be:

  • validated for fuel efficiency by the US EPA based on SAE testing;
  • sufficient for standalone compliance with 2010 CARB regulation supporting trailer aerodynamics;
  • exempt from US DOT length restrictions verified in an FHWA compliance letter provided to all TrailerTail® customers.
  • The device opens with one touch and closes in 5 seconds.
  • In the open position, it boosts fuel economy by 5.1% at 62 mph, according to SAE J1321 Type II fuel economy testing.
  • In the closed position, it folds flat against swing doors to enable normal access to cargo.


Grabbed this tuft testing image from the video as well:
