The bus components are first described in terms of how they are modeled. Then a variation of each component is performed and the resulting fuel economy and performance are presented as sensitivities and tradeoffs. The comparison of test track relative fuel consumption to simulated relative fuel consumption was accomplished with six of the nine simulations agreeing within the plus and equal 1% band of the test results as specified in the SAE Type II J1321 test procedure.138
