As a popular bumper sticker on semi-trucks reads, without trucking America stops. This applies to the logistical transportation industry around the world. There is no easier way to get goods from point A to B. Governments around the world have started to force the commercial vehicle industry towards improved efficiency due to the rising concerns over fossil fuels.

Both the US EPA and the State of California have approved ARC as an official testing site for measuring aerodynamic targets, ensuring that government mandates are being met. The advantage of the ARC scale model rolling road wind tunnel is that accurate testing can be done at the lowest cost compared to previous governmentally approved methods. In fact, previous methods are at best +/- 1% accurate on fuel economy improvements, while ARC's tunnel can produce +/- 0.25% accuracy. 


ARC solution packages offer the following:

  • Fleet Efficiency Analysis
  • SmartWay Verified Aerodynamic Testing
  • SmartWay Test Report Documentation and Writing
