Designed for the toughest loads
The cooling system in the Audi RS Q e-tron is designed for maximum loads. “We last secured the thermals in Morocco in November,” says Sebastian Fröber. “Carlos Sainz traversed the soft sand of a dried-up riverbed with deliberately taped cooling air intakes in a lengthy test. All systems worked flawlessly.”
Despite all the power losses evident in the cooling requirements of power units, Audi has built a rally prototype with high efficiency. In the world of motorsport, this vehicle is a milestone for long-distance driving with its electric power transmission and energy converter. The TFSI engine, which runs on around 200 kilowatts of power, is extremely efficient when operating between 4,500 and 6,000 rpm. Its specific consumption is well below 200 grams per kilowatt hour. As a result, Mattias Ekström/Emil Bergkvist, Stéphane Peterhansel/Edouard Boulanger and Carlos Sainz/Lucas Cruz in the Audi RS Q e-tron not only hurry through the desert at the Dakar Rally at a good temperature, but also particularly efficiently.
