All assembled car parts undergo real torture: the doors get closed 30,000 times, seat cushions and back rests get brushed 20,000 times and each control button gets pressed 5,000 times. These are some examples of the most severe tests that a car has to pass before its future owner takes possession.
Most of these tests are carried out when the model is still a prototype. Others are performed on all production cars, immediately before they leave the factory. The goal is to guarantee the quality and reliability of the parts, as well as of the car as a whole. 55,000 safety tests are performed each year on a car including driving 30,000 km with gravel impacts and having 2,500 L of water poured on the car in 10 minutes. Testers drive 2 million kilometers every year, testing all models of cars before they reach the dealership.
