ATDYNAMICS is a Silicon Valley based clean transportation technology company and the leading global supplier of semi-trailer rear-drag aerodynamics technology.

Our Products

ATDynamics designs and manufactures a suite of clean technology products engineered to reduce the fuel consumption of the global freight transportation industry.  By REDEFINING THE SHAPE OF THE MODERN TRACTOR-TRAILER, ATDynamics’ trailer aerodynamics technologies are reducing the fuel consumption and associated greenhouse gas emissions of global trucking fleets by 12%.

The Company’s flagship TrailerTail® product line alone will deliver over $40 billion in fuel savings to trucking companies and consumers over the next decade by streamlining the airflow at the back of over 4 million long-haul semi-trailers traveling on US and international highways.


Every TrailerTail® equipped semi-trailer offsets the equivalent greenhouse gas emissions of removing one passenger vehicle from the road.
