Musk: Cyber ​​trucks will have excellent aerodynamics


Editor’s note: This article is from “Tencent Technology”, proofreading: Jiao 晗, 36 氪 reprinted with permission.According to foreign media reports, although Tesla’s latest Cybertruck did not make its debut at the Los Angeles Auto Show in November, it is still the most talked about car recently.Last weekend, Tesla CEO Elon Musk said on Twitter that Cyber ​​trucks could have incredible aerodynamics.Despite the boxy body of the Cyber ​​truck, Musk said that as long as there is “extreme hard work,” the pickup truck may have a drag coefficient of only 0.30.Musk said, “With extreme effort, Cyber ​​trucks may reach a drag coefficient of 0.30, which is incredible for a truck. We need to adjust many small details.” In contrast, when the Dodge RamsWhen the latest generation of Ram 1500 pickup was released, FCA claimed that it was the most aerodynamic half-ton pickup with a drag coefficient as low as 0.357.Vehicles equipped with active grille shutters, removable front windshields and a reduced-speed air suspension system all help reduce unnecessary air resistance.In support of his claim, Musk mentioned that cyber trucks can achieve laminar flow, in which case air flow can move substantially undisturbed on the surface of the object, thereby reducing drag.Tesla pickup’s smooth underbody also helps make that possible.In contrast, the bottom of conventional trucks is usually extremely irregular, and steering components, axles, drive shafts, frame rails, and countless other components can generate unwanted air resistance during driving.Musk also said that the hard edges of Cyber ​​trucks help improve aerodynamic performance.Intentionally directing the air flow around the wheel is another trick that reduces drag.Cyberpick’s covered cargo holds should also help improve aerodynamic performance.Musk stated on Twitter that “(The shape of the cyber truck) is conducive to achieving a low drag coefficient. How to smooth the air flow at the edge of the car body and guide the air flow around the wheel is like an invisible sculpture. Tesla is great for manufacturingAerodynamic cars are no stranger. Even if it looks like Lego bricks, there is no reason why Cyber ​​trucks do not have shocking aerodynamic characteristics. Tesla Model 3 electric car has a drag coefficient of 0.23. Model X is consideredIs the least resistance of all SUVs at present. YouTube users have posted an interesting video about the aerodynamic performance of cyber trucks. They run some cyber truck models through some computational fluid dynamics software to get a rough idea of ​​how air is inThe test results were surprising when flowing around the vehicle body. When driving at 140 km / h, the video publisher estimated that the drag coefficient of this car is about 0.30, which is consistent with Tesla’s statement. The body is as smooth as possibleIt is essential to improve the efficiency and performance of the vehicle. It is said that the single mileage of a cyber truck can exceed 500 miles, 0 to 60 mph in less than 3 seconds. This pickup can also tow objects weighing 6 tons. At present, Tesla has not commented on the aerodynamic performance of Cyber ​​trucks.
