How fuel-efficient is a bus?

Transit buses are a LITTLE more fuel-efficient, but not as much as many people might think. A car (24.2 MPG) with the national-average of 1.5 passengers gets 36.3 PPMG (Passenger Miles per Gallon). A transit bus (3.3 MPG) with a national average load (9.1 passengers) gets 30 PPMG.

A diesel engine requires less fuel to produce the same output as a gas engine. A conventional gas engine operates via a spark ignition system, which burns more fuel than a diesel engine's combustion system. As a result, diesel buses are more fuel-efficient per gallon and burn less fuel while idling.

The United States. In general, most American transit systems expect their buses to have a useful life of 12 years and 250,000 miles. This time frame is due to the fact that, after their buses have been around for 12 years, they are eligible to receive replacement bus funding from the federal government.
