Test Procedure
The test procedure was based on TMC Fuel Economy Test Procedure – Type IV, RP 1109B.
  • One test consisted of three valid test runs.
  • One test run consisted of one complete test route, which was divided in two segments, the midpoint being situated at 173 miles from the start.
  • Trailers and drivers paired with tractors in the first test segment were consequently switched to the other tractors during the following test segment.
  • Fuel consumption was accurately measured by weighing portable tanks before and after each run. Two portable tanks were used for each vehicle, one for each test segment of the run. The test vehicles were also instrumented with flowmeters and onboard computers for obtaining supplementary data.
  • By utilizing weight measurements and portable tanks, PIT Group exceeds TMC IV testing standards. Gravimetric measurement compensates for temperature variances which effect volume, but not volume.
  • The total fuel consumed by the tractors when pulling each semi-trailer and being driven by each driver was calculated. The results of the complete test were expressed as fuel efficiency in miles per US gallon (MPG) and as a fuel savings percentage.
