Testing for Improved Truck and Bus Fuel Economy

The TMC/SAE Type I and Type II tests were developed jointly toy the SAE and the American Trucking Associations' Maintenance Council (TMC) with sponsorship from the Voluntary Truck and Bus Fuel Economy Program. The tests allow truck and bus operators and others to evaluate products and designs for fuel economy using a drive cycle of their own choosing. To encourage the use of this procedure and provide unbiased information to the industry, the Voluntary Program has begun a series of “New Energy Concepts Tests” to evaluate products and ideas.
