Q: Does a TrailerTail® really save fuel?
A: Yes, The TrailerTail® fuel savings have been proven in on-road SAE Type II third-party tests. TrailerTail® will deliver 5.1% fuel-
efficiency gains at 62 mph and over 6% at 68 mph or greater. The patented TrailerTail® design lowers vehicle fuel consumption
by reducing low-pressure suction drag directly behind a trailer. ATDynamics TrailerTail® technology delivers over twice the
fuel-efficiency gains of any other commercially available rear drag reduction technology and is the only rear-mounted
aerodynamic device which allows fleets to fully comply with 2010 CARB trailer aerodynamics regulations.
Q: How much fuel will a TrailerTail® save?
A: Each TrailerTail® added to long-haul trucking operations will deliver between $1,000 and $5,000 each year in cost savings. Use our Fuel Savings Gauge to determine your fleets potential savings, or use the table below:

Q: How quickly will a TrailerTail® pay-off?
A: TrailerTail® will pay for themselves in less than a year for high mileage trailers. ATDynamics will work with dedicated fleets to provide customized financing plans.
Q: How does a TrailerTail® enhance the safety and performance of a tractor-trailer?
A: Because the TrailerTail® streamlines airflow and minimizes turbulent vortices behind a trailer, truck drivers notice less sway at the backs of their trailers and improved visibility when using their rear-view mirrors during rain or snow. Trailing passenger cars experience both a smoother ride and a decrease in hazardous road spray, plus, without the drafting benefits of suction drag,
they have less incentive to harass truck drivers by tailgating dangerously close to the rear of tractor-trailers.
Q: Is it legal?
A: Yes, the TrailerTail® is the only device to officially demonstrate compliance with DOT regulation CFR 658.16(b)(4) which allows
for a 5 foot extension for non-cargo carrying aerodynamic purposes.ATDynamics will work with fleet customers to ensure that appropriate documentation from the DOT is laminated to the lower panels of all TrailerTail® devices.
Q: How does the TrailerTail® benefit the environment?
A: Each trailer driving with the TrailerTail® for 50k miles or more per year reduces the carbon dioxide it releases into the atmosphere by over 4 tons. The annual emissions savings from two TrailerTails® is greater than the CO2 that the average passenger car emits in a year.
Q: How does a TrailerTail® impact the loading and unloading of cargo at docking bays?
Patented TrailerTail® design allows drivers to operate swing doors normally. The device opens with one-touch and collapses in less than six seconds flush against the doors for normal loading / unloading.
Q: What about rain/ice/dirt/grime?
By streamlining the airflow at the rear of vehicles, the TrailerTail® reduces the turbulent spray behind a trailer and leads to lower snow, dirt, and grime accumulation on trailer doors. All latching mechanisms have been tested in
snow and ice conditions.
Q: How long does a TrailerTail® installation take?
The TrailerTail® is designed to require 2 people 2 hours to install. Installation time will drop in large fleet roll-outs.
Q: How do I purchase TrailerTail® technology for my fleet?
A: TrailerTail® is available from your local trailer dealership, OEM installed
and from ATDynamics directly. For more information click here or request a quote. |
