Fuel/Energy Economy

Fuel Economy

The objective of this test is to provide accurate comparable fuel consumption data on transit buses produced by different manufacturers. This test bears no relation to the calculations done by the Environmental Protection Agency. The results of this test will not represent actual "in service" fuel economy but will provide comparative data (read full test procedure).

The test is performed using a large-roll chassis dynamometer.

Energy Economy (Battery Electric Buses)

The objective of this test is to provide accurate comparable energy consumption data on battery electric transit buses produced by different manufacturers. This energy economy test bears no relation to the calculations done by the Environmental Protection Agency (EPA) to determine levels for the Corporate Average Fuel Economy (CAFE) Program. EPA's calculations are based on tests conducted under laboratory conditions intended to simulate city and highway driving. This energy economy test, as designated here, is a measurement of the energy consumed by a vehicle traveling a specified test operating profile, under specified operating conditions that are typical of transit bus operation. The results of this test will not represent actual mileage, but will provide data that can be used by FTA Grantees to compare buses tested using this procedure (read full test procedure).

The test is performed using a large-roll chassis dynamometer.
