Decades of inertia dynamometer testing in multiple regions have led to a myriad of fixture design philosophies and methodologies, with substantial effects on the test results. In addition, in the current landscape of the automotive manufacturing industry, vehicles are designed in one location, manufactured at another location(s), and sold all over the world with significant differences in environmental conditions during their life cycles. Efforts to reproduce vehicle-level conditions and environmental factors in the laboratory setting lead to redundancy, conflicting results, or high-variability in test results of the same test program.
