1. A method of automatically generating a simulation model for evaluating performance characteristics of an automotive propulsion system that includes a plurality of subsystems, the method comprising: capturing automotive propulsion information from a first simulation environment indicative of an existing simulation model characteristic of an associated automotive propulsion system, the system including a plurality of automotive subsystems and at least one level; converting the automotive propulsion information from a first format to a second format; storing the automotive propulsion information in the second format in at least one file; selecting a plurality of subsystems for inclusion into a second simulation model, the plurality of subsystems being characterized in the at one least file; converting the automotive propulsion information from the second format to at least a portion of a third format; building the second simulation model in a second simulation environment from the information; and analyzing performance characteristics of the constructed simulation model, thereby enabling determination of a desired form of the automotive propulsion system.
