“Like most carriers we take fuel economy seriously and we believe this test will help validate the decisions we make about our equipment,” said Gerry Mead, senior vice president of maintenance at U.S. Xpress. “Using a proven process and a certified and highly experienced team from PIT Group will provide solid test results on fuel economy. We look forward to the results.”

For the U.S. Xpress evaluations, PIT Group has identified a 60-mile test course on highways and local roads.

To represent typical fleet operations, U.S. Xpress fleet will pull trailers with loads of equal weight.

An in-cab observer provided by PIT Group will accompany U.S. Xpress drivers operating the test vehicles. U.S. Xpress will also provide fuel, technicians and maintenance facilities for the event, including a mobile service truck if required.

PIT Group In-Service Fuel Testing utilizes TMC Fuel Consumption Test Procedure – Type III (RP 1103A).

The industry standard test compares the fuel consumption of one component of a combination vehicle to the same component in another combination vehicle. PIT Group uses an ISO- 17025 certified process conducted by engineers dedicated solely to providing accurate unbiased test results on fuel saving technologies.

“We are very pleased that U.S. Xpress counts on our expertise to select the best vehicle specs for its fleet. Having so many vehicle and component manufacturers that decided to take part in our first U.S. In-Service Fuel Testing, shows the value of independent testing for both fleet and suppliers” said Yves Provencher, director of the PIT Group. “The real-world data about the fuel consumption of a variety of powertrain combinations that we are collecting will be very valuable to PIT Group Members as they make specification decisions and to suppliers as they design and develop new technologies.”

As an added value for PIT Group members, results will only be available to members and U.S. Xpress.
