Utmost precision in design and construction was imperative for the testing grounds used for the technical development of passenger cars produced in the Shanghai Volkswagen plant. This sophisticated research facility comprised a high-speed circular track of approximately 4.7km length, a handling course, an endurance course and an alternating course, a driving dynamics platform and a braking test track. A special drainage system, precisely fitting to research requirements, stretches over the whole compound, spanning 2kn approximately.
