1. A system for evaluating an engine to determine the driveability of a vehicle incorporating the engine without mounting the engine in the vehicle, the system comprising:

  • running condition simulating means for generating a load of the engine corresponding to running conditions of the vehicle and for imposing the load on the engine while the engine is operated on a test bed;

    operating parameter detecting means for detecting engine operating parameters including a speed and an output torque of the engine when the load is imposed on the engine by the running condition simulating means;

    driveability data generating means for generating, based on the detected operating parameters, driveability data corresponding to at least one driveability condition of the vehicle, wherein the at least one driveability condition would be directly perceived by at least one human sense of a vehicle operator in operating a vehicle with the engine mounted therein; and

    sense-data generating means for converting the driveability data into stimuli which can be directly perceived by the at least one human sense in a manner corresponding to the direct perception of the driveability condition by the at least one human sense during operation of a vehicle equipped with the engine.
