A transit bus fuel economy testing procedure, developed and verified by proving ground tests, will enable the motor coach industry to evaluate vehicle modifications and components without lengthy revenue service operations. This procedure is based on the proposed SAE recommended practice for type 11 fuel economy testing of heavy-duty vehicles. The procedure was used to evaluate the fuel economy effects of turbocharged diesel engines, air conditioning, axle ratios, diesel fuels, bus weights and oil additives. Verification testing was conducted in July 1980 as a joint effort of the government, the SAE and elements of the transit industry. For the covering abstract see IRRD transit industry.
