According to foreign media reports, the newly released cybertruck, although not appearing at the Los Angeles Auto Show in November, is still the most talked about car in the near future. Last weekend, Elon Musk, Tesla's chief executive, tweeted that the Saibo truck could have incredible aerodynamic performance. Despite the boxy body of the Saibo truck, musk said that as long as there is "extreme effort", the resistance coefficient of the pickup may only be 0.30. "It's incredible for a truck to have a drag coefficient of 0.30 as long as you work extremely hard," Musk said. We need to adjust a lot of small details. " In contrast, when the latest generation ram 1500 pickup truck of Dodge Ram was released, FCA claimed that it was the most aerodynamic half ton pickup truck with a drag coefficient as low as 0.357. The vehicle is equipped with active grille louvers, movable windshields and a speed reducing air suspension system to help reduce unnecessary air drag. In support of his claim, musk mentioned that the Saibo truck can realize laminar flow, in which case the air flow can move on the surface of the object without interference, thus reducing resistance. The smooth underbody of the Tesla pickup also helps. In contrast, the bottom of traditional truck is usually very irregular, steering parts, axles, transmission shafts, frame guide rails and numerous other parts will produce unnecessary air resistance during driving. Musk also said the various hard edges of the Saibo truck helped improve aerodynamics. Deliberately guiding the air around the wheels is another technique that can reduce drag. The cabins of the SEB pickup should also help improve aerodynamics. In twitter, musk said the overall shape of the [cybertruck] is conducive to low drag coefficients. How to smooth the air flow around the car body edge and guide the air flow around the wheel is very important, just like an invisible sculpture. Tesla is no stranger to making aerodynamic cars. Even if it looks like Lego building blocks, there's no reason for the Saibo truck not to have shocking aerodynamic characteristics. The drag coefficient of Tesla Model 3 electric car is 0.23. And is considered to be the least resistance of all. At present, YouTube users have released an interesting video about the aerodynamic performance of the Saibo truck. They ran a cybertruck model with some computational fluid dynamics software to get a rough idea of how air flows around the car, and the results were surprising. At 140 km / h, the video publisher estimates that the drag coefficient of the car is about 0.30, which is consistent with Tesla's statement. A smooth body is essential to improve the efficiency and performance of the vehicle. It is said that the single endurance mileage of the Saibo truck can exceed 500 miles, and the time from 0 to 60 miles is less than 3 seconds. The pickup can also tow objects weighing six tons. Tesla has yet to comment on the aerodynamic performance of the Saibo truck.
