When it comes to motorsport, people may first think of the Formula 1 Grand Prix, which is more difficult to control than a fighter jet and the costly event, and may think of all kinds of strange corners and the WRC World Rally Championship that flies on the dirt road, but in terms of operational difficulty and race difficulty, Dakar is the most difficult pure in motor sports. In this event, not only the winner is the hero, just like the marathon, it is not easy to complete the entire course.
"How? Still dreaming of a driver? The sound of Peng Cannon rang out from behind me, interrupting my thoughts as I watched the Dakar report.
"Not really, just care about the game, Dakar is no better than other games, can finish the game is a hero," I did not look back, casually replied.
"Is it so dangerous? Isn't it just an off-road rally? ”
"In the past, there were always cars buried in the desert from time to time, and people who were not rescued in time were gone, but this year because of the war in nearby countries, it was safer to take a detour."
"Is it so exciting?" I remember there used to be a Chinese how many times did I go to the race and became famous? ”
In fact, the biggest highlight of this year's Dakar is not the detour or the situation in the Middle East in 10 years and 9 battles, but Audi's use of the new energy model RS Q e-tron to participate in the world's toughest and most difficult off-road rally event. The slightly more complex name of the vehicle is clearly the product of Audi's multi-division cooperation, RS is Audi's high-performance division, Q represents the car belongs to the SUV sequence, and e-tron indicates that this model uses an electric motor as the power unit. Perhaps considering the hardships of the event, or perhaps not too assured about the endurance, this time the RS Q e-tron did not directly use the form of pure electric to participate, but used the situation of extender electric mix.
Of course, in order to cope with the severe test of Dakar, Audi is also quite careful when building the RS Q e-tron. Friends who have watched desert cross-country races may know that it is very easy to fly on the desert at high speed, although the driver will try to avoid such a situation, but many times the phenomenon of taking off is inevitable, then the balance of the car becomes particularly critical, coupled with the complexity of the road conditions of the event, the forward grille hitting the air intake design is obviously not very practical. The RS Q e-tron uses a mid-range extender (engine) setting, and the position of the power battery is close to the front axle to achieve perfect balance.
After solving the layout problem, another thing worth The Audi has to worry about is the heat dissipation problem. Although the RS Q e-tron is a racing car, it still uses the same single-stage reducer as on civilian new energy models, and the electric motor is simply not equipped with a gearbox. This means that when the vehicle is faster, the faster the motor rotor speed, the higher the temperature of the motor naturally, coupled with the harsh arena environment, the heat dissipation problem is indeed very important. To this end, Audi has developed a special cooling system suitable for high-heat and high-pressure environments, one of which is called NOVEC' non-energized coolant is the key to the whole system, but in fact, this is not a breakthrough in materials science, this Chinese coolant called fluoride has been used in the fire extinguishing device of electronic equipment and the cooling device of large servers, but the cost is high.
So when we look back at the performance of the Audi RS Q e-tron, we find that although we all say that we can finish in Dakar is already a hero, but now Audi is not just trying to finish, the champion of four stages, and the cumulative 14 stage podium results, shows the good strength of the Audi RS Q e-tron. Coupled with the fact that audi RS Q e-tron cars collect up to 50GB of relevant data every day, I believe that after compiling and optimizing these data, the RS Q e-tron can play a better role in the next event.
"You should be talking about Lu Ningjun, the first Chinese to participate in Dakar, participated in Dakar 7 times, and when he first went in 2003, CCTV broadcast it all."
"Do you remember that clearly?"
"Well, the first live shot is that the desert is trapped in a car, and the people of the whole country watch him dig sand..."
"Hahaha, didn't old Lu regret dying?"
"But how people say that they are also the people who open up this road, although many Of the Chinese drivers behind him have achieved better results than him, he is the most memorable"
Write at the end:
Perhaps a group of new energy manufacturers look at the Audi RS Q e-tron to participate in the Dakar Rally, just like we saw Lu Ningjun participate in the Dakar is the same mood, although the results are not ideal, but it represents countless possibilities in the future. When new energy models can achieve good results in the world's most environmentally demanding events, it is of great positive significance for the promotion of the entire new energy vehicle. We also look forward to Chinese new energy vehicle companies showing their technical style in such a race.
