Drag Coefficient – Engineering ToolBox, Tesla Model S – Wikipedia, Drag Coefficient – Engineering ToolBox, 11/2/2020 · Tesla Model S’ Drag Coefficient The drag coefficient number of Tesla Model S is 0.24. At the same time, its frontal area is 25.2 square feet (2012 Model S). This results in a mere 77 pounds of drag force exerted on Tesla Model S.
The measured drag coefficient Cd and Strouhal number St of the single cylinder are presented in the figure 4, for Reynolds numbers between 2.0 × 10 4 and 5.5 × 10 5. Also presented are the measured drag coefficients by Güven et al. [ 7 ], for a smooth cylinder and a cylinder with a surface roughness of k/D = 1.59 × 10 ? 3.
The company initially claimed a drag coefficient of Cd=0.24, lower than any other production car when released. Independent measurement by Car and Driver in May 2014 bore out Tesla’ s claim by exactly confirming a drag coefficient of Cd=0.24. As of 2019, Tesla specifies Cd=0.23 for the Model S .
6/29/2015 · As impressive as the Model S’s drag coefficient of 0.24 has been until now, it seems that Audi has been able to achieve an even better figure of 0.23 Cd with the all-new Audi A4 sedan: Model S Model 3, The drag coefficient is a function of several parameters like shape of the body, Reynolds Number for the flow, Froude number, Mach Number and Roughness of the Surface. The characteristic frontal area – A – depends on the body. Objects drag coefficients are mostly results of experiments.
