The giant unit allows you to create the conditions of any climate zone, and the temperature can be changed at a speed of up to 10 ° C per hour. Only seven hours is enough to transfer from the hot (+ 40 ° С) tropics to the ice tundra (-30 ° С). Moreover, make the test car race at a speed of up to 300 km / h … without moving.
That, however, is not all. In the pipe, special lamps imitate the scorching southern sun, nozzles create tropical rain, and a snowstorm can burst from the hose. It is not surprising that a 140-meter device consumes 15 megawatts of energy - it would be enough for a town of 3000 inhabitants!
The novelty was subjected to severe tests not for the sake of measuring the Cx coefficient - Mercedes has its own pipe, but to make sure of the capabilities and catch the weaknesses of the Termatika, which is responsible for the microclimate in the cabin. Its volume is no less than 4.5 mz, moreover, it is separated from the environment not only by blank walls, but by a windshield of 1.5 m2 and a transparent hatch - another 1.2 m2. In general, heat evaporates easily - will there be enough 10 kW allocated for heating to create a comfortable temperature? By the way, such thermal power is just enough to heat the cottage, but it does not blow a hurricane wind at -20 °!
The R320CDI diesel engine has such a high efficiency that the interior does not have enough coolant heat, and the designers had to add a 1.7-kilowatt electric heater. If there wasn’t such an “assistant,” a driver who wanted to warm himself would freeze the motor.
