An engine virtual test environment system may include at least one memory and at least one processor configured to perform a virtual engine test and generate a virtual engine to which a physics-based model and a data-driven model are applied to replace an engine. The at least one memory may be configured to store a physics-based model representing the actual structure of an engine by any one of simulation, phenomenological relationship expression, physical characteristic change of constituent elements, a combust model, an ECU model, and an engine model, and a data-driven model representing the actual operation of the engine by any one of a test model, a mathematical model, modeling, engine DoE techniques, mathematical and statistical techniques, a driving range.
