The wheels turn on the rollers, the car stands still and is additionally cooled. A cylindrical test room, which allows you to measure a lot of important parameters in the laboratory, is not uncommon. However, if you need to “squeeze” a car with four times supercharged 16-cylinder with an output of at least 1600 hp and 1600 Nm, you need a special machine. This is what the French carmaker shows.

The testing machine is able to test speeds up to 480 km / h. Although this is an incredible number, it is only slightly higher than the limited maximum speed of chiron, ie 440 km / h. However, even at lower speeds, the forces are enormous.
–
After all, at a speed of 420 km / h, chiron tires turn more than 50 times per second, which can exert a force of about 4,000 G. At these speeds, the air valve weighs up to 55 kg, says Bugatti.

To ensure that the car remains securely attached at all times, it must be secured with 20 high-strength bolts that attach to specially designed adapter plates on the monocoque.

Each board is then tied to the other thick chains crossing and anchored to the hall floor. The chains must withstand a force of up to 24 tons to keep the car in constant contact with the rollers.

The powerful fan in the test hall, meanwhile, can supply up to 300,000 cubic meters of air per hour to simulate realistic airflows above the car and supply the engine and cooling systems with the required airflow.

“This means that we can guarantee free and above all safe operation even at full load and maximum speed,” said Gericke. “We can also reproduce the tests at any time of the year and regardless of the weather. This helps us in our constant search for technical excellence. “
