A modern rain simulation system has been incorporated into the circuit for testing all aspects of performance and tire usage, setting the track apart from other circuits.
Portimão Circuit is one of the few circuits within Europe to have this advanced system, which operates by means of an asphalt watering system controlled automatically by a modern software system that allows varying amounts of water to be injected onto the track. The paddock also has a system that allows you to create a wet zone, which becomes a 1,000-metre straight where you can also specify the quantity of water required.
With this system, the track is equipped to respond to the requirements of teams testing cars, motorbikes or tires. This system allows different levels of water to be used according to the instructions of each client. It also means that different track areas can be irrigated independently using varying amounts of water in each sector.
