What is a proving ground and what types of testing are conducted there?

A proving ground is a dedicated vehicle test facility with specialized road surfaces and tracks for vehicle validation. Common features include: High-speed oval for maximum speed and stability, handling track for dynamics evaluation, durability surfaces (Belgian blocks, potholes, washboard), off-road courses, grades and hills, noise evaluation roads, and climate chambers. Proving grounds enable controlled, repeatable testing under varied conditions year-round, supporting development, validation, and benchmarking activities.
